Ok as the title says I went N-at and now I am having problems. It is a self put together kit using some DSM parts because I am working to get the money for the other stuff. But I ran the car with no O2's and i studders when I rev and studders when I hit boost. It is also running very rich when I am at WOT. am when I idle the Wide band is all ove the place some times at rich some times at lean. It also some times does not idle at all. The O2s are no hooked up and when I ran the codes I got a bad 24 and a 26. I also fixed the idle a little bit by bolting down the ECU a little better. Any help would help alot.

 

The stock ECU needs input from the O2 sensors, otherwise it will run like crap. You could install one and jumper the input to the the second sensor input.

I have my O2s hooked back up tho.

 

how does it run now with the o2s hooked back up?

 

Would this not imply you have some loose wiring somewhere?

Runs exactly the same.

 

It ran the same when I tried to reground it tho.

 

Do you still have your map or mas? if its disconected or not pluged in it give the same symptoms your mentioning... - Bryan

 

reset the ecu sounds like a boost leak to me. btw you only need 1 o2 sensor just splice them together and make sure they are far away from the turbo it will melt and cause a fire ask how i know lol.

oh and what the hell are you regrounding?

 

The ECU I heard that could be a problem with bad idle

New problem. Sometimes when I am driving it will all the sudden just die and go way lean and then start going again. Only on low throttle tho.

Also the check engine and trac light come on some time and the car dies a little at idle. and the CEL and trac light go way when I get about around 2500rpms

 

Tried it and the car would not run at all. could not rev and it would not idle.

 

I am running no O2's and my car runs good. lol

 

You arnt running any 02s at all?

 

No O2's at all on a stock ecu with no piggy back lol.
