Hi All,

Just wondering, what sort of crank / cam signals do the RWD Northstar engines have (pre 2007 E67 versions)? I know the earlier ones had twin crank sensors, but I would be certain this has changed on the E67 based ones.
Retrofitting those earlier ones that have the stupid Siemens PCM would be an interesting project, especially when the Shelby 4.0L Northstar uses an LS1 PCM :shock: (See this Ebay Motors Item number: 230237506492)
Also, anyone know how well a 4L60E might bolt up to one?

Thanks,
Ross

I have the same thoughts on these engines. Interesting...:)

There has been a little talk of running early model Northstar's on a 0411 pcm of late.

But a E67 sounds like fun to.

You don't happen to have a 0411 pcm tune file for a Northstar do you Ross?

I think you might find the 4L60E will bolt up well, I would be very surprised if it was a no go.

The N* IIRC has the V6/FWD trans bolt pattern. So you would need a S10 or other narrow trans housing.

But the nice thing is after 95 or so, all the 4L60E's had removable bells....

I know I personally have thought of a 0411 swap in them, but they have so much headgasket issues, and so darn pricey to fix, i would rather toss in an 0411 PCM and a LS4......

The issue really is running the engine is easy, but running the FDC (Fuel Data Center) and other high tech electronics is unknown territory.....

Yes, but it's quite different to the LS1, looks like custom Shelby. Interestingly though they must have run a 2bar OS on those maybe? And for the life of me I have never been able to find out what crank pattern they had!


The N* IIRC has the V6/FWD trans bolt pattern. So you would need a S10 or other narrow trans housing.

I just recall on Wiki there is something that says the RWD versions of the N* (I like that!) was modified greatly for RWD. From that I assume they were modified to bolt right up to a RWD trans.

I would think that wouldn't be too hard, the catch, the crank/cam sensor res.You could fab up a crank pulley with the correct reluctor wheel and run the CKP sensor from there.

I don't know what the N* cam reluctor/tone wheel looks like, I bet it's different...
could possibly add the correct tone wheel to one of the cam sprockets.

Electronic Ignition (EI) System Description

http://i224.photobucket.com/albums/dd25/AJxtcman/Ignition%20systems/EI.gif


The Ignition Control System for this Powertrain controls fuel combustion by providing a spark to ignite the compressed air/fuel mixture in each cylinder at the correct time. The ignition control system has several advantages over a mechanical distributor ignition system.


No moving parts to wear out.

No mechanical load on the engine.

Elimination of mechanical timing adjustments.

Located for easier service and improved reliability.

Improved high engine speed performance.


The Ignition Control System consists of the following components:


Two crankshaft position sensors (A and B).

Crankshaft reluctor ring.

Camshaft position sensor.

Ignition control module.

4 separate ignition coils.

Eight spark plug wires and conduit.

Eight spark plugs.

Knock sensor.

Powertrain Control Module (PCM).



System Operation
The Ignition Control System does not use a conventional distributor or a single ignition coil. In this ignition system, both ends of each of the four ignition coils are connected to a spark plug. Each coil is connected with spark plugs on companion cylinders, i.e., on top dead center at the same time (1-4, 2-5, 6-7, and 3-8). One cylinder is on its compression stroke when the other one is on its exhaust stroke.

When the coil discharges, both plugs fire at the same time by using the engine block to complete the electrical circuit. The cylinder on the compression stroke is called the event cylinder and the one on the exhaust stroke is the waste cylinder. The two cylinders share the energy available from the ignition coil to fire both spark plugs. This method of ignition is called waste spark ignition.

Since the polarity of the ignition coil primary and secondary windings does not change, one spark plug always fires with a forward current (center electrode to ground electrode) and its companion plug fires with a reverse current (ground electrode to center electrode). This is different from a conventional distributor ignition system that fires all the plugs with the same forward current flow.

It is possible for one spark plug to fire even though a plug wire from the same coil may be disconnected from its companion spark plug. The disconnected plug wire acts as one plate of a capacitor and the engine block acts as the other plate. These two capacitor plates are charged as a spark first jumps across the gap of the connected spark plug. The plates are then discharged as the energy is dissipated as the spark continues. Voltage requirements are very high with an open spark plug or wire. The ignition coil may have enough reserve energy to fire the connected plug at idle, but possibly not under some engine load conditions. A more noticeable misfire may be evident under load; both spark plugs may then not fire.

Crankshaft Position Sensors and Reluctor Ring
The two crankshaft sensors are located on the front bank (BANK 2) of the engine block between cylinders 4 and 6. Crankshaft position A sensor is located in the upper crankcase and crankshaft position B sensor is located in the lower crankcase. Both sensors extend into the crankcase and are sealed to the engine block with O-rings. The crankshaft position sensors are not adjustable.

The magnetic crankshaft position sensors operate similar to the pickup coil in a distributor. When a piece of steel (called a reluctor) is repeatedly moved over the sensor, a voltage will be created by the sensor that appears to go On-Off-On-Off-On-Off. This On-Off signal is also similar to the signal that a set of breaker points in a distributor would generate as the distributor shaft turned and the points opened and closed.

The reluctor ring is cast onto the crankshaft between the #3 and #4 main bearing journals. The reluctor ring has 24 evenly spaced notches or air gaps and an additional 8 unevenly spaced notches for a total of 32.

As the crankshaft makes one complete revolution, both the A and B sensors will produce 32 On-Off pulses per revolution. In addition, the A sensor is positioned 27 degrees of crankshaft revolution before the B sensor. This creates a unique pattern of On-Off pulses sent to the ignition control module so that it can recognize crankshaft position.

Camshaft Sensor
The camshaft position sensor is located on the rear cylinder bank (BANK 1) in front of the exhaust camshaft. The camshaft position sensor extends into the rear cylinder head and is sealed with an O-ring. The camshaft position sensor is not adjustable.

As the rear cylinder bank exhaust camshaft turns, a steel pin on its drive sprocket passes over the magnetic camshaft position sensor. This creates an On-Off-On-Off signal sent to the ignition control module similar to the crankshaft position sensors. The camshaft position sensor produces one On-Off pulse for every one revolution of the camshaft or every two revolutions of the crankshaft. This allows the ignition control module to recognize camshaft position.

Ignition Control Module
The Ignition Control (IC) module is located on top of the rear camshaft cover. The IC module performs several functions:


It monitors the On-Off pulses produced by the two crankshaft and one camshaft position sensors.

It creates a 4X and 24X reference signal (4X REF HI and 24X Crank) sent to the PCM for ignition control.

It creates a camshaft reference signal (CAM HI) sent to the PCM for fuel injection control.

It provides a ground reference (REF LO, CAM LO) to the PCM.

It provides a means for the PCM to control spark advance (BYPASS and IGNITION CONTROL) called IGNITION CONTROL MODE.

It provides a limited means of controlling spark advance without PCM input called MODULE MODE.

The IC module is not repairable. When a module is replaced the remaining components must be transferred to the new module.


Ignition Coils
Four separate coils are mounted to the module assembly. Each coil provides the spark for two spark plugs simultaneously (wasted spark ignition). Each coil can be replaced separately.


Base Ignition Timing
The base ignition timing is determined by the relationship of the crankshaft position sensors to the reluctor ring. This relationship is not adjustable and results in a base ignition timing of 10 degrees BTDC.

IC Module Mode
There are two modes of ignition system operation: PCM mode and Ignition Control Module (IC Module) mode. In IC Module mode, the ignition system operates independently from the PCM. The ignition control module maintains a base ignition timing of 10 degrees BTDC and is able to change this ignition timing slightly with increased engine speed. IC Module mode is in effect whenever an ignition control fault is detected while the engine is running and it will have a noticeable effect on driveability. In PCM mode, the PCM controls the ignition timing. The PCM calculates the desired ignition timing based on information it receives from the input sensors.

PCM Timing Mode
The Powertrain Control Module (PCM) controls spark advance and fuel injection for all driving conditions. The PCM monitors input signals from the following components as part of its ignition control function to determine the required ignition timing:


Ignition Control Module (IC Module).

Engine Coolant Temperature (ECT) sensor.

Manifold Absolute Pressure (MAP) sensor.

Transaxle Range (TR) switch.

Throttle Position (TP) sensor.

Vehicle Speed Sensor (VSS).

Knock Sensor (KS).


http://i224.photobucket.com/albums/dd25/AJxtcman/Ignition%20systems/CRANKSENSORS.gif



The crankshaft reluctor ring has 24 evenly spaced notches plus 8 additional notches (shaded) used for synchronization.

As the crankshaft rotates, the notches pass the position sensors and create a voltage pulse signal in the sensor that is an input for the ignition control module (ICM).

Because of the physical location of the 2 crankshaft position sensors, the signal of B lags the signal of A by 27 degrees of crankshaft revolution.

To synchronize the ignition, the ICM first counts the number of B pulses between every 2 A pulses. There can be 0, 1, or 2 B pulses between A pulses.

When the ICM sees 0 B pulses between A pulses , it starts counting B pulses between A pulses. When the ICM counts exactly 4, it synchronizes the ignition on the very next A pulse. If the ICM counts over 4 (jumps from 3 to 5), it waits for another B pulse between A pulse to start counting again.

This process allows the ignition to synchronize and fire the first spark plug within 180 degrees (1/2 engine revolution).

The camshaft position (CMP) sensor provides the ICM with cylinder #1 firing order information, which the PCM uses for sequential fuel injection.

Using 3 sensors allows the ICM to maintain ignition synchronization even if one of the 3 sensors fails.

All FWD 1996 to 1999 Northstars either Oldsmobile or Cadillac run a Delco PCM with a SERV. NO. 16214848

All 1999 RWD run a Delphi PCM & SERV. NO. 9354896
Lyndon has the software to tune


In 2000 they repositioned the crank sensors and redesigned the notches on the crank. So the block and PCM have to match at this time

All 2000 to 2003 run the same PCM. It is the SIEMENS. They had several SERV. NO. but they all supersede to one number. The PCM in my hand is a 12562481 and I know it is not the latest and greatest number.

All 2004 and 2005 FWD used a Serv. NO. 12587465 PCM. I think the is a E22, but it is not GMLAN. This has Transmission functions

The Shelby setup use all the stock GM sensors. They added one more. It is a Rough Road Sensor. It as a G sensor mounted Verticaly.

The 99 uses the stock crank and cam sensors. It used the stock coils.
The 2001 the Shelby Series II used the later style engine with 8 coils and the newer cranks sensors. This car was just a prototype, so I can't get my hands on the Cal ID. :secret:

Thanks CalEditor. The one you show as 2004 & 2005, does that do trans as well? I have a couple of those, one black, one not, but the same service number.
I also have a Siemens TCM that was supposedly from the same vehicle, but I was under the impression the 2004-2005 engine computer does trans as well. Why else would it need 2 x CPU's!

Ross,

TC (John), has packaged his software and customized it for a number of vendors.

Jet Performance Products have purchased gas and diesel rights to the software. In doing so, the original unlimited version of TC was taken from the market. A limited number of original TC customers are still supported via John directly.

Westers Garage (Lyndon Wester) has a version of the TC software customized for his customer bases. Westers has also supported a scan tool (PCM Scan) to work with the TC OBD2 interface. I would imagine this is what you see.....Correct Tom?

Flash Chips (Ed Wright) may have a version of the TC software as well. Don't know much about this or if this information is correct. I have seen a version of the flash utility in the flashchips colours...:)

The Only other Tuning Software I know of is the Real Time Roadrunner software supported via Craig Moates, God bless his mortal emulation soul.....LOL..Yep once you tune realtime it hurts to go back.

MxScan (James Brimson) supports the Monodax forum and the MxScan scan tool software. I earn for the day that further developments in this software are made public as the GUI layout looks interesting.

Until then, I will enjoy the use of EFILive.....:devil_2:

The 2004 and 2005 have Trans functions. It uses the the same block, crank, and crank sensors as the 2000 to 2003.
The 2006+ uses one crank sensor monted under the intake manifold.
The 2006+ run a E67 and a TCM. The 2004 and 2005 is not an E67. I can not find any ID markings, but I think it is a E22. It looks similar to the E22 used in the 2004 XLR. The XLR uses GMLAN/CAN and a TCM. The Sevice #'s are different between the two. I have a whole lot of XLR info, but the files are too big to send you.

September 5th, 2008, 06:39 AM
Well, I can tell you for sure, you don't wanna know WHERE it is.... We won't go into what it is....


What is a "crack sensor"?

IIRC the module gets crank/cam sensor inputs but still waits for EST signal from the PCM telling it the delay (+ or -) on when to actually trigger the flyback.

So the sensor inputs might need to be tweaked if the N* and LS1 use different crank triggers. should be quite easy really.

2000-2001 Cadillac Controllers - A communication error may occur at the end of the reprogram in the TIS software. If you receive this error once the progress bar goes to 100% you will not be able to reprogram this controller.
all 2000 to 2003 FWD Northstar PCM's interchange


1999-2003 Corvettes & Cadillacs - GM Requires that a Star Adapter be used during reprogramming the PCM in-vehicle. The controller can be reflashed Off-Board without any problems. Check any TSB's on the vehicle to be sure it requires the adapter.

The 2000 to 2003 could not be programmed in the car until the MDI came around. Some times the MDI will fail on the first attempt, but goes through on the second. If you use the MDI and the J45211 it works ok the first time.
The issue with doing it in the car is 80% with the PKIII system. If you unplug it the program goes through

So the LS1 pcm can control a N*?

s10mods come on now :doh2:

The LS1 PCM was used on a 99 Northstar FWD engine in a RWD application from the factory. This was a very small run of a car.

The 2000 Northstar is very different from the 99 engine. The Crank sensors are different and the reluctor ring is cut different. The 2000+ are COP also

In 2006 they redesigned the FWD engine again and uses a single crank sensor, the cam sensor is moved to the intake cam from the exhaust and it uses a E67 ECM

93 to 99 engines are similar 93 to 95 are SD and have no MAF. You can adapt and 93 to 99 to run on the 99 LS1 program and PCM
