Hey guys.
I got done my manual swap and left the auto harness and computer in the car. I started it and the car started up fine but the car idels a little rough which from what i have read is normal bc of the auto computer. Anyways the car is so rich when ideling. The wideband reads 10.0 and by the smell of the exhaust you can tell that its rich.
Anyone know the reason or a fix for this? Is this something that could be adjusted in the tune?? want to break the clutch in then take it down to ptuning to get tuned but dont want to waste my time taking it down there if its running like this.
Any help would be great!!
Thanks
Chris

 

I would just change to the Manual ECU to save the headaches. Congrats on getting everything done. P-tuning did a manual swap, so they can probably help you out.

 

^^
Thanks Bryan!
Ya I just messaged them so hopefully I can get some kind of info from them.
Im so burned out working on this thing!!! LOL I dont want to have to change out the harness and computer but if I have to I guess I will. Kinda to late to turn around now!! LOL

 

i didnt know you could run a manual with an auto ecu

 

Yeh man, i didnt even think that your car would work with the Auto Comp. You better be careful, because you windeband can only read to 10.0. you very well may be in the 9's for your AFR and that can be dangerous. How does the tune/afr's look under load/ while driving? Does the car feel quicker?

 

IDK yet havent road tested it yet. Will hopefully be doing that tomorow.

 

i have the auto ecu still in aswell.. chris when u find out what ptuning is let me know whats needed exactly to swap to the manual ecu? do we have to override something i think i read? i have no idea let me know pleaseeee

 

The immobilizer? Yea, you have to jump 2 points on the obd port if i remember correctly. Then turn the ignition on with your key and let it sit for like 15 minutes. I had the notes on my comp somewhere from a while back.

 

Im running my auto ecu and harness just fine Idle at about 14.5-15.3.

 

i didnt know there was a handful of people that actually swapped. Good job guys

 

Chad Julio knows how to program the ecu in the car whn you change them. Ask him. He did it with mines switching ecu on my car.

 

I'm running auto ecu too and it actually idles fine. I bought a manual ecu but didn't know how to trick the immobilizer so we just left the auto ecu. but if anyone knows how to trick the immobilizer let me know.

 

I attempted to take the car up the road and the damn thing felt like it couldld even get out of its own way and it was sputtering all over the place.
Well then disconnected the battery and thew in the stock injectors. The car started fine and seemed to idle better. Took the car up the road and it drove waaaayyy better. But it was still sputtering just a little bit. The wideband was still in the 10's but it did come up into the 11 and 12s a little bit.
Still have no idea where to go from here.

 

double and triple check every is connected around the motor, also make sure one of the grounds is going to the transmission.

 

Yup I checked my connections and I have the grond on the trans. I went ahead and dissconnected the F/IC and now instead of the car running rich now its running lean. Totally went the other direction!!
Toan is thinking its my o2 senser that could be doing this I am going to pick up another senser and see what happens I guess.

 

Well..
I went and got the o2 senser and replaced it. I was hopeing so much that it would be the problem.
NOPE! it wasnt the anserew!!! Nothing changed after changing the sensor out. I want to put my head through a wall right now I am so stumped right now and it sucks so bad!!!
What else could be causing this??!?!?!
Mabey MAF??
something else?
please anyone I really need help with this right now!!!

 

So right now you are saying you have your stock injectors in, and your FIC is not plugged in. You are running lean. Maybe put your 550's back in and that will be enough to drive it to somewhere to have it checked.

 

Ya mabey I have a trailor if I need it. Mabey I can take it to ptuning in the trailor or something

 

Yeah, I got my tahoe to pull it if you need it.

 

Thanks bryan. I have a truck to pull it but if I run into a problem ill keep you in mind thanks!!
But I dont really want to have to do that, it will be a last resort thing. I would like to try to fix it myself.
Anyone have any suggestions??
