You need that wire connected to the sender in the fuel tank. The fans I will cover shortly.

This is JUST the injectors that are in the picture above.

Where can I find that? if it is E40?

What wire size do I need?

Is the wire size mentioned in those schematics? and is het metric?

Like:
2540
RD/WH
0.5

Thanks AJ,

There is E38 stamped into the metal casing of the ECM.

I think I understand most of it above. I'll have to check in the garage tomorrow.

Any idea where to get new connector pins for the ECM connector? I don't have any wire in C1#1 park/neutral signal...

Great job on the photoshop!

No Photoshop here. I get messed up in the version I have and it never comes out right.

I learned something today. I started thinking about this and it made sense so I checked in my notes. You are correct.

2006 = E38

05 was an E40

Two questions allready, just by looking.
- The RD/WH alt wire comming from the alternator is thinner (0.5mm2) than the alt wire in the American Auto Wire classic update kit. This one is stock color brown, 1mm2 thick and has 13 strands. Orginally it is not fused and it goes to the ignition switch. Could this one be useable if fused correctly? if not I have many options for voltage sensing in the AAW update kit.

- In you schematics you show circuit 439 and 1439?
I need to put ignition voltage on both? ECM pins C1#19 (MM6) and C1#47 and does C1#59 Ingintion relay control has anything to do with these? I havn't seen it on the schematics jet...?

Thanks

Can't I just turn off that sensor using HP Tuners?

CalEditor

iTrader: (1)

Yes you can turn off the DTC's, but not the sensor input.

The Fuel Level Sensor does just a tad bit more than give information for the EVAP System.
Why did an OBD1 car have a Fuel Level Input?

I have several pages to go yet

Ok, but does the stock 1971 camaro fuel level guage sender give the same voltage/resistance output? I don't know anything about OBD1 car stuff, or for that matter OBD2 stuff either really... I'm just trying to figure it out. In any case, if the pcm is looking for a certain resistance from the fuel sender, could I use an appropriate resistor in that circuit instead? To fool the computer into thinking the tank was full? I don't want to run the evap system either.
I was under the impression that I could remove certain things (evap, 2nd O2 sensors, vats, skip shift solenoid, reverse lock out solenoid, fuel level sender)((that I rememberanyway)) and then disable them using a tuner program, and that that would work. If you are saying that that will only stop codes from coming up and that the car will run in limp mode, then I need to rethink this entire thing.

The ECM Needs to see the Fuel Level Change at Fill UP to reset. I will look over my notes, but if I remember correctly when testing if we had the Fuel Tank Level set to full the ECM DID NOT Reset certain parameters at key cycle. We did this with a resistor so the ECM read full all the time.

Now I need to do the Trans. That is great because I have that very setup right next to me.

pjtimmer

WOW! GREAT STUFF!!! I will lock myself up in the garage tonight!


- Another question about the fuel level signal the ECM needs:
What is the normal resistance at full? and what is the normal resistance at empty?

I have a two wire in tank fuel level sender that reads 0 Ohm @ empty to 90 Ohm @ full for the Autometer gauge. Would that work?


- Another question:
I do NOT have the fan speed control module from the corvette unfortunadly. Besides that I have a dual 18"> 16" fan setup from a Lincoln Continental.
Is there another way to use the fan speed controle wire from the ECM to run my dual fan setup? I prefer: low speed single fan and high speed dual fan.
Is this possible to make?


THANKS

How is the RUN/CRANK relay in the circuit above ever going to be tripped? Another way of asking the question is what is driving the Starter Enable Relay Control signal from the ECM to ever go low? Normally this would be handled by the ECM after receiving instructions over the CANBUS from the BCM. Without the BCM, how would it work? I'm not trying to be critical. I'm just asking for clarification in case I missed something.

No crank run relay any more and the starter hmmmmm.
I guess I need to look at the Cal file and see what needs to be switched over.
