What ECM should I choose?

[JoakimMD]

As the topic says: What ECM should I choose?

My requirements are:

-Petrol
-V8 (3,6 L if it matters)
-One output per injector
-One output per spark plug
-Able to control turbo wastegate
-Ofcause tuneable with EFILive!

Thanks in advance!

Maybe I should explain more... It´s an Audi 3,6 L V8 from 1990 that I will see if I can get to run with some kind of GM ECM. Why GM? I have EFILive and I can buy the ECM very cheap. Will get away with a one tenth of the price of an aftermarket ECM, e.g. Bosch Motorsport.

Ofcause there will be some work with a new wiring harness, fit new senders and sensors, spark plug module etc to match the new ECM.

So a new GM ECM for $150-200 and a new EFILive license. Can´t get any cheaper! :)

As long as I get a suitable ECM I will get it to run. Just a matter of time and patience. I see this as a challenge.

Any ideas?

Thanks, Joakim

I've heard of people making the LS1 PCM & Harness work with FORD motors...

I am trying to do somethieng simualr but with a kawasaki jet ski its a 1500cc sc 4 cylinder motor. the problem is there are no tunable ecms available. soooooo . :doh2:

I vote for the 0411 PCM as GAMEOVER said.

EFIconnection makes a 24x crank reluctor that mounts on the crank pulley for SBC/LT1, but it could probably be adapted...

You might have to get creative with the cam reluctor.

But, it appears he is looking for "Coil Near Plug" for a V-6. That is going to be the difficult part.

I've been working with a company that is developing what will be a relatively low cost system that will allow 411-type ECMs to be use to control virtually any popular US V8 engine. The problem with systems like the one from EFI Connection is that the parts are very expensive. That's not meant as a slam, the expense is a result of the production costs. But if you can eliminate some specialized parts, system cost is reduced. I'll have more details when testing is completed.

[JoakimMD]

Thanks for your input!

Why not use the E38/E67 ECM? Doesn´t they support COP and VE table for forced induction? 58 crank wheel sounds nice. More Bosch like that would be easier to find for an Audi engine i suppose.

Took a look at the LSx 0411 ECM also. That would be my other choice. Also COP and with custom OS support forced induction.

Although the GM ECM's are nice, in your case I would be looking at an aftermarket ECM, sure not cheap, but I think for all the issues you will have with the crank/cam signals and different sensors (or adapting GM sensors to the Audi engine) you might be better off not using a GM ECM.

[JoakimMD]

GMPX: I do not agree with you. Fiting sensors is the smallest issue. Cam signal is no problem. Will use the location where the distributer was. Building a wiring harness, no problem. Have build a number of them erlier but stand alone for Duramax. Same, same but different

The only thing I am concerned with is the crank wheel/signal. Since I have numerous contact with people that can CNC manufacture that for me I don´t think that will be a problem either.

Where is your problem solving spirit?? I think you post was a bit negative. :) This is a side project that has no time line. The car is stripped down to pices and will take at least a year until I trow in the engine

The thing I would like to know is what stock ECM that fits in my project. I have already explained why.. Have the tuning software and can buy ECMs cheap.

Anyone else that can comment my post?

Is this a dummy distributor based system with crank/cam signals within? This would be a universal approach as all early popular V8 engines have provision to turn a distributor.

Have heard of a few people trying this by running the crank signal out of the distributor...well what can one say ? :shock: PCM thinks distributor is drunk. :) But why not give it a shot!

Looks like you could select from either a 0411 or an E38 or an E67. :)

[JoakimMD]

Ok, thanks everyone!

More questions...

I have an engine on its way home. Its an Audi S6 4,2 liter V8. So soon will I start to get this together. :)

What ist the different between the ECMs? The 0411, is that the E40?? If not which one is that?

The Virtual VE in E38/E67, is that much work to get right? I´m just aming for 150-200 kPa of boost

The 0411 is an LS1-style PCM-- the E40 is an ECM (no powertrain control functions) and was first used in 2005 on Corvette. It's also used in Trailblazer SS. Virtual VE tables aren't that bad, but personally, I'd use a 411-type PCM and a custom operating system.

Also when choosing a PCM/ECM keep in mind that 2005 and earlier systems used a 24-tooth reluctor ring, 2006 and later a 58-tooth reluctor ring.

Ditto what dfe1 said. VVE is a walk in the park if you put the effort in. Though you should probably start with an OS for an engine that is as close as possible to your engine displacement. Some will no doubt disagree with me on this, but having been there...:)

I wouldn't call it a dummy distributor as it's fully functional. We have a few engines operating with this system but have a few bugs to work out so installation is easy, even for novices.
