I may have one sitting in my shop...I pulled one out of my car since I went carbed, my car is an 89 re that originally had a 305, but when i pulled out the ECM it had writing on it (appers to have come from JY) I think it say the year...86 or 87 v8 on it...your welcome to it...

if your ECU is from an RS, then it was a TBI car, so it is a different computer than his 5.7 TPI would use.

yes, if its for tpi cars. ill grab it when im down for the dyno. but yea if its for an rs then it work work with mine.

Thanks

are you driving the car in question down?

If so we can try plugging mine in.

BigBoi4Lyph · Posted: Mon Dec 08, 2008 7:35 pm Post subject:

yes i will be driving it down.

yea that would be sweet too. i just dont have a scan tool i can actually bring with me. so maybe one of you guys have one that can read live data.

but yea that would be sweet.

thanks for the offer!

We've got plenty of stuff we can read data with. I have a cable here... didn't want to connect to Dewey's car, but it's the same design I've built 4 other times that work. Plus Dewey and Schultzy each have a cable I built somewhere. We can read with Tunerpro or Moates old school data logger.

I have an Auto-X-Ray also.

sweet! that sounds great. yea i have to figure out why i cant read live data. and then go for their on "what i think" is a rough idle, and possibly a little under powered. but i could be crazy so im sure i can get some good input from you guys.

thanks

Without a wideband you're kinda shootin in the dark on the lack of power.

BigBoi4Lyph · Posted: Tue Dec 09, 2008 10:01 am Post subject:

a wideband so i can read my mixture more accuratly?

the dyno should help tell me if im underpowered to huh?

and i just found a 350 pcm with prom all stock on tgo guys shipping to tommorw for 45 in all. woo! haha

i dont have any tunning equiptment yet. i need to but nothing i have on my car should nessasarily "need" a tune. but i could be wrong? full exhaust, bosch type 3 injectors 22# deleted air,air condition, and EGR, k&n and air foil.

what do you think?

aaron_sK · Posted: Tue Dec 09, 2008 12:41 pm Post subject:

Is deleted EGR throwing a code?

BigBoi4Lyph · Posted: Tue Dec 09, 2008 2:06 pm Post subject:

no suprisingly. since day one its been deleted and no codes and no egr code history when i first bought the car either.

thats why im going to try and different pcm and prom becuase maybe mine has been programed or something. who knows.

haha.

but yea no cel for egr ever.

Twilightoptics · Posted: Tue Dec 09, 2008 2:47 pm Post subject:

Lots of times the EGR wont throw a code as long as you have the noid connected. You should turn it off with the chip though.

BigBoi4Lyph · Posted: Tue Dec 09, 2008 3:20 pm Post subject:

noid?

im assuming your not talking about injector noid lights haha.

nothing is hooked up for egr the egr itself is removed, the solinoid is gone, egr temp sensor unplugged everything just wires left hanging out.

humm now you have me thinking. maybe im transposing my old 90 formula and this iroc haha.

i think the 90 had an egr temp sensor.

i dont know anyways everything for the egr is gone and disconnected.

so this noid thing you mentioned? whats that?

No mine did have an egr temp sensor.

Noid = Solenoid

EGR solenoid. It's what switches the vacuum on and off.

BigBoi4Lyph · Posted: Tue Dec 09, 2008 5:26 pm Post subject:

yea the egr solinoid is gone.

so maybe the prom already has the egr disabled?
