Yup. I'll download, upload and then edit your post with the URL ;)


OK

[Tordne]

TTT - Link updated.

[TAQuickness]

thanks buddy

[Doc]

Awesome, it's been raining alot here lately;)

[TAQuickness]

same here. I've got almost all my new gadgets hooked up now.

[Tordne]

I can't decide whether to wire to FlashScan or to the EGR system :help2:

[redhardsupra]

example of what can you achieve with FP logging:

[ringram]

Nice one dude. A convert to efilive too by the looks :D

[TAQuickness]

Great write up Marcin!

I was looking over the files you sent Friday and was close to asking for a lot of the explainations you provided in the blog.

Good luck on your thesis. I'll try to hold off on the tarded questions while I apply your findings to my tune.

[jsttry]

Just following this guide with a few alterations (didn't get the harness, was provided with a 3 wire hand made version). All has gone well. Yet to test it out, that is tomorrow job.

Am worried as the sensor is a lot longer than the bung out of my Aeromotive regulator so don't want to wind it in too far and damage the reg. Also assume I'm going to have to go find some tape to seal it up like was on the original bung.

[TAQuickness]

I don't think you want to use tape on the fuel system. I believe liquid sealant is what you want to use.

Got pic of your install?

[jsttry]

Was thinking of doing pics but my PCM isn't in the factory location so didn't worry too much, and it was dark :) Will pull the camera out this afternoon after work and take a few.

[jsttry]

got the sender mounted yesterday and went to plug it in. As soon as you plug it in and go to turn the key on the PCM throws a error code saying the TP Sensor is low voltage. Tried to start the car and it ran like a pig.

Have followed the guide and connected to EGR. Have enabled EGR in the tune and confirmed I get 5V to the plug. PCM is a 1999+ in a Holden Commodore.

Has anyone else successfully connected using the EGR method in a Holden Commodore?

[Tordne]

I have.. Did it some weeks back.

[jsttry]

Andrew, can you send me some contact details so I can have a chat?

Have checked and am using the correct pins as described in the tutorial but as soon as I plug into the FP sensor I get a DTC error code thrown relating to low voltage on the TP (Throttle Position) sensor.

Did you tap in on the blue connector or the red? Should be Blue, unless your PCM is different from the 99's here in the US.

[jsttry]

Yep, all 3 wires were tapped into the blue connector

[Doc]

Hello all,
I am just about done with my FPSU project. I am using an Autometer 2246 just like in the tutorial. I am using the EGR connection right by the oil cap on the passengers side (fbody). I got the wrong autometer pig tail connector for the sending unit. I did notice that it (the sending unit) is exactly like an ECT sensor plug. I have an extra ECT sensor pigtail but I don't have the sending unit's pinout. All the tutorial says is
Red = 5vdc
Black = grnd
ppl = 0-5v sig

This is fine if you have the orignal autometer connector. If anybody can help tonight it would be great. I am loading up the trailer for the track tommorrow and would love to have some track FP data to log.
TIA

[Tordne]

The the pins facing towards you:
Red is top left
Black is top right
Purple is center bottom

[TAQuickness]

Thanks Tordne. I was just scratching my head trying to figure out what I could do to help the Doc.

[Tordne]

I sent a couple of pics as well :)

[Doc]

Update: Works good, lasts longtime!

[Tordne]

Did it change the IFR angle for you as well?

[jsttry]

Am going to be flying out to Sydney shortly but I'll have to catch up with you next week Tordne to sort it out.

[Tordne]

Cool mate, have a safe trip.

[joecar]

Have fun in Sydney... :cheers:

[redhardsupra]

the link up top is dead, please fix it

[Tordne]

The tutorial is actually included in the installed software. But I'll update the link as well.

[BowlingSS]

Has anyone installed this sender and checked their fuel pressure? Does it have to be this exact sender? I was thinking about adding this to my car.

Thanks,
Bill
:cheers: :cheers:

[Doc]

I have and it works as advertised. I suppose you could use any 0-5vdc pressure sensor with the proper range. The autometer isn't expensive though.

It is like $140 at summit for the harness and sensor.

[Doc]

Don't bother with the pigtail. Just goto your dealer and get a 98 ECT sensor pigtail. You don't need the length of the autometer harness- well you should'nt if you are planning on using the existing EGR wiring.

I was not sure if I just wanted to wire straight to EFILive or go thru EGR wiring. It looks like the EGR might be the best way. My car is a 2001 without EGR.:beer:
What do you think Doc?

Bill

[Doc]

Yeah Bill, I was thinking of that when I left off last- 2001 no egr.(Busy putting in my motor right now) No worries. You can still run the wires from the pcm it'self. The EGR option is the easiest to take advantage of a power supply and voltmeter on a system that is not used on your car.

I agree! The EGR for the 5V supply works great and data feed for the EGR volts set to a custom PID is beautiful!

Is the wiring harness already wired for the EGR or will I need the pins and wiring? What size pins are in the PCM connector? I have not looked at the PCM yet.
Thanks.
Bill

[BowlingSS]

Just got the sender and harness in. My wires are different collors than what is in the tutorial. I have a purple and a black and gray. The purple should be the 0-5vdc signal. I assume the black is ground and the gray is +5vdc. Does that sound right?

Thanks,
Bill
:cheers:

[BowlingSS]

I got this wired up to my EGR PCM pins. Thanks DOC for your help and PCM pins. It is working great now. My Fuel Pressure is running about 60 at idle.

Thanks everyone for the help.

[oztracktuning]

Anyone does this with Australian cars?

[VT LS1 NZ]

Anyone does this with Australian cars?

I have it working fine on mine.
Just had to add the wires & enable .

[ntae]

Anyone does this with Australian cars?


yes

[oztracktuning]

In Australian cars are the wires there already or do the connectors with wires need to be put in ie. are they vacant.

[VT LS1 NZ]

You have to add the wires for the EGR output to be used.So yes they are vacant.
I got a couple of PCM plugs from a Automotive Dismantler to obtain the wires.

I've had no issues using this method.

[ntae]

All the holdens with LS1's i have done, i make up a harness & plug it in to the egr pins on the pcm ,turn on the egr (B1301) load the cal pids and start loging

The auto meter sender looking at the plug is wired

earth pin A .......power 5 volt pin B

............output pin C

[oztracktuning]

Thanks for that info Geoff

Im just waiting on some more pins. But when i checked my pcm harness one of the pins i thought that was for EGR was used. What are the pins again?

It works great. It saves buying another gauge.
Bill

[oztracktuning]

I just logged mine at the track with 155 dry shot of Nitrous. The FP went down slowly as rpms build to as low as 39psi :), it drops smoothly under any load. My car would have a bit over 600rwhp with a shot that size.

[Whippled2dr]

I just picked up the 2246 sensor and a TPS sensor pigtail and was wondering if I have the pins labeled correctly for the sensor in the below pic. Thanks

http://i3.photobucket.com/albums/y73/99bluetahoe/Fuel_pressure_sensor.jpg

[ntae]

yes that,s right

[Whippled2dr]

Cool, thanks.

[Superado]

thanks for the write up...
my efilive v1 should arrive today and I have this mod installed and ready to log...

[TAQuickness]

Welcome to the forum Superado.

[Superado]

thanks for the welcome!
i spoke too soon, however...
both the egr & the sender have different color wires than the wiring instructions...

sender has black, grey & blue

egr has brown, red, grey, purple & white

any suggestions?

thanks,
al

2000 Chevrolet Silverado

also edited post above...forgot the purple egr wire...

[Superado]

I have just found the egr harness info for the truck...thanks to cablebandit

from the gm dvd info on the egr harness,
brown 0-5
grey +5vdc
purple gnd

the pin config. of my sender...
http://shed51.com/sensors.htm
which is the same as the AutoMeter fp sender's configuration:
http://i172.photobucket.com/albums/w39/Superado/atm2246-po.jpg

and the pic of my sender pigtail below,

http://i172.photobucket.com/albums/w39/Superado/gpi-1.jpg

we have come up with this...
sender/pigtail to egr harness

Blk (gnd) to purple (gnd)

Grey (+5vdc)to grey (+5vdc)

Blue (0-5) to brown (0-5)

[TAQuickness]

Good find. Sorry I wasn't able to get back to you sooner.

[Superado]

Good find. Sorry I wasn't able to get back to you sooner.
thanks for the reply yesterday...
you must've replied as soon as I walked out the door to go to dinner last night...

[Superado]

OK...someone on LS1TECH caught this before you guys...

I was looking at the plug end of the pigtail the same as the sender's pin out, which is incorrect because it is actually a mirror of the sender...

The CORRECT connections are:
sender/pigtail to egr harness

Grey (gnd) to purple (gnd)

Blk (+5vdc)to grey (+5vdc)

Blue (0-5 signal) to brown (0-5 signal)

[Superado]

it works!
and logs!

[Superado]

question...
now that I have the egr reading fp...how do I turn off the SES light due to egr?
thanks

[TAQuickness]

Set P0400 - P0405 to "Not Reported" and "NO MIL"

[Superado]

Thanks!

[TAQuickness]

de nada

[voda1]

I'm having problem sourcing the -4an female to 1/8 npt female adapter fitting mention in the tutorial. Any help appreciated.

got mine from the local Hydraulic Supply

http://www.hydraulic-supply.com/html/rrlocal.htm

[mr.prick]

I used a regular NPT to flare adapter from my local hardware store.
No leaks.
IIRC it is 1/2" to 1/8"npt
6430

[voda1]

Everthing I come across in female 'an' is swivel.

Edit:

Found something but is of 2pc -
-4AN female to 1/8 npt male adapter -- Russel #614204 or Earl's #916104
1/8 npt female coupler -- Russel #661440 or Earl's #991001

Came across 1pc design:

[pullincrazy88]

way old post but im wondering if you can hook this up to work through the egr on my truck. it is a 2000 k-series and i am running the 411 pcm swap on cos3. would be using an AEM fp guage.

[mr.prick]

If you can log voltage through the EGR and you can get the slope & intercept to convert
voltage to FP, then yes.

[monzaaddict]

Can anyone see why this sensor wouldn't work instead of the autometer 2246.

(J.C. (240)P399AAC-1C PRESSURE TRANSDUCER O TO 100 PS1S) can be found on ebay for less than $60 and bolts directly to the schrader valve port without removing the valve - no need for adapters. Its advertised as being designed for measuring refrigerant pressure but the literature says it can be used with any non corrosive fluids.

Here are the specs
http://www.vikingcontrols.com/_documents/Product/125515.PDF

Do most people permanently install their sensor or remove it after they are finished logging fuel pressure?

[Tordne]

Looks like the 1/4 in. SAE one might be correct. From my reading this seems to be that same as -4an (though I wouldn't trust me on this entirely).

When I had my LS1 I had the sensor installed permanently. Remember, just because it's there doesn't mean you have to log it all the time if you don't want/need to.

[mr.prick]

They are designed for use in commercial refrigeration and air-conditioning applications.
:nixweiss:

I've had the AutoMeter sensor installed for a few years now and it still works. :hihi:
Honestly I don't look at the PID too much tho.

[69camaro5speed]

looking for a connector that fits the egr valve connector has any one seen or heard of one,after hooking up my fuel pressure gauge to my egr plug(sliping wires in connector and testing it)I was thinking it would be nice for when I do customer's car's to have a egr connector for quick hook ups (so i am not cutting there wires)any ideas

[ferocity02]

Just got mine hooked up to my '01 Silverado. I used grey for 5V, purple for ground and brown for 0-5V signal. The colors were different than what the tutorial says.

Idle pressure is about 52 psi and is within 0.5-1.0 psi of what my mechanical gauge says. Overall I'd say it works pretty well!
