Sounds like you may have a vacume leak. Does the idle bounce up and down alot? then settle out and run rough?

Guessing that since you are not mentioning AFR or wide band that you just assuming slapping a map on the car and assuming that it runs right?

check ur vaccum lines etc... when converting to single there is a heap of vaccum outlets of the throttle body that need to be blocked up

Welcome to tuning. Get a wide band, search the forum here and the Datalogit forum and you have everything you need. The short-cut is doing it the right way.

I don't think tuning is an issue, it got to be a vacuum leak or something is not plug in right. This happen to me and it turns out to be the TPS, check the commander for the TPS.

it has nothing to do with the tuning, the motor just isnt running right, somethings not hooked up.

Speaking of being a dummy.. I did that the other day too.

I was trying to tune the idle.. and then i looked at my datalogit.. and it took me a good 2 minutes to notice the P row wasn't moving when i revved...

Stupid map sensor
