I've had the SC for about 20k miles and now the bearings are starting to fail. The car is burning oil about a half quart in the past 3 days. and I just got a CEL.... prob for an O2 sensor. I used a half tank in 86 miles and I can smell raw gasoline in the muffler after I turn off the car.

I want to go back to stock for now. Does anyone know how I can get the ECU back to stock?

Thanks,

Why don't you just take the car back to the dealership? Is it out of warranty already?

 

he has an nst pully, it would be voided anyway.

 

Ahhh I c in his sig now. Hmmmm. I'm of no help so....bump.

 

i think garage1217 knows how. i think all he requires is a donation or something because he put alot of work into figuring it out.

 

yeah, here you go

Bah I will just give it to the masses now as a few have donated which added up to 50% of what I had to pay to get the info... I appriciate those who donated for all the crap I had to go through to get this document.

You have to get an ecu of the same year and tranny type.

How to make the new ecu work is at the very very bottom of this page. You do not have to have any special tools other than a wire to link two obd2 pins together. It is under "Engine ECU replacement" Worked like a charm for me

Thanks so much for the info..... This may seem like a dumb question, but where is the DLC3? and also....

do I have to put the stock sized injectors back in?

Thanks,

Yes put back oem injectors / also that pinout photo is of the obd2 port under the dash by the door on the drivers side. It is blue in color.

 

Even if you remove the SC and get a new ecu -if you are burning oil and the primary cat is shot, it will take more cash to get the car back to health. Have you done a compression check yet?

 

If the main cat is gone, I have a spare I can sell "whole header assembly with cat with less than 1K miles.

 

how much?

 

My thoughts exactly. Compression check!

 

wow you had to pay for that? how much?

i found a free TSB site some time ago.
