5 speed swap having problems

[DropTopStang88]

Car is shaking and idleizing very high don't understand need help

 

[Wicked One]

Did you change the computer? Do you have a tune for the 5.0?


There are a few variables that need to be seen by the puter. # of cylinders, firing order, injector pulse, tps settings ETC................

Need as much info as possible before we can pinpoint your problem.

What was done after the motor swap, what year........

You get the point.

Thanks.

I didn't change the computer no its 2002 v6 I got a 2003 tranny spec stage 2 clutch and flywheel. That's what I know so far but I have a tuner from sct I had the computer tuned b4 with the auto

 

[DropTopStang88]

I don't have the tune for a 5.0 though

 

[Wicked One]

Theres your problem.

You need to upgrade the puter to a 5.0. All the parameters are set to the old motor. I will do some research and see what I can find to help you out.

Good luck, I will see what I can find for you.

Thanks man I appreciate the help

 

[Wicked One]

That's what we do here at NYM. We help out all we can.

I think its the flywheel I was looking at reviews for my flywheel there's somthing about a weight or something

 

[Wicked One]

The weight would not cause an idle surge. That is controlled by the tps (throttle positioning sensor). If your flywheel threw a weight it would shake the motor, not cause running problems.

The tps controls idle measures and also WOT for the puter.

 

[Chevy_Guy]

TPS doesn't control anything. It tells the ECU where the throttle is. IAC controls the idle.

 

[NYstang]

Theres your problem.

You need to upgrade the puter to a 5.0. .

what? its a V6

 

[1980rustang]

^i saw that too no where in the thread it said he did a swap or it had a v8 swapped in

 

[Wicked One]

OOPS My fault. I thought he did a motor swap

This is tranny issue. sorry.

and correct the IAC controls idle, but you need to make sure that the tps is set correctly or the iac will be doing nothing but adjusting for the wrong curve.

 

[Gingerbreadman]

if u bought a new flywheel,not sure,u should have counter weights that u either put on or are already on,,i know the later 5.0 had a 50oz imbalance and early have 25,,so check that,doing a swap to 5spd shouldnt do anything to your idle and engine performance,,check and set tps,check iac,if still nothin,,check vaccum

Ok so should I get a 5.0 computer or a 99-04 computer I'm going crazy here with this car can someone take a look at it

no and no.


first- did you have your car TUNED for the 5 speed, or are you on the tune you had made when you had an automatic? if thats the case, you need to get a new tune, as the computer is still trying to control the tranny. I would recommend VMPtuning.

 

[DropTopStang88]

Yea it was tuned for a auto I got the sct tuner can I use that to tune it when the new tune and if not where can I get the tune from vmp tuning

 

[NYstang]

you can use the tuner, but you need a whole new tune, since its not the ecu's job towork the tranny now.
