i was helping a friend the other night tune on his car. we got the part and wot down pretty well, but it bucks and surges its *** off when leaving a stop light. some of that is the clutch, but alot of it is in the tune. its a turbo car with a big inch motor and a realtively small camshaft. i saw that there are 2 tables that have to deal with map corrections by tps voltage, but i didn't know which one or which way to adjust them to remedy the problem. i was looking in the transient fuel menus, but if anyone has a better idea i'm all ears.

 

ttt...

 

Your on the right track. Look at the AE vs TPS and the AE vs MAP Fueling tables. Watch your O2 reading when it happens and verify if it is going lean or rich then make the appropriate changes.

 

it seems like i keep loosing the tps... sometimes i get a reading, sometimes i dont. i'll replace it and then keep messing with those tables. thanks
