if you are getting a SES light and the code pops up as TPS then find someone with a VQ35 with a running motor. Swap throttle bodies and if it starts up and runs you found your issue. It could be wiring, or a bad throttle body.

 

Ok. That's going to be a pain, I don't know that many people with the same car that would be willing for me to use parts if they're car...any one want to help in that's in s. Florida. My car is at Olympic Motorsports in margate.

 

i'm sure there are plenty of people. You can find a TB for sale on the forum normally around $80. less if its local.

 

yeah. i cant find any on the forum right now. should the open loop fueling on the utech be on or off? i remembr we tried to scale the injectors and it didnt let us. i am wondering if that was the problem. the screen said that it was "for later use only" or something. and didnt allow us to adjust them.. any advice?

 

sounds like a huge pain in the *** your having!!!

sounds like whoever sold you that kit ripped you off...

try going to junkyard for a throttle body

 

there are guys parting out entire engines in the marketplace...they have TB's. I've seen them.

As for the UTEC, you need to read and re-read the installation manual located on the link i sent you. It has all the information and if your tuner is half decent he should understand what it does if he reads the manual.

OPEN-LOOP fueling is for highly recommended for FI guys. You will max out the MAF tuning options around 4.5 PSI. You need to use the MAP sensor.

 

Correct me if I'm wrong, but I thought the MAF sensor was good for up to 7/8 psi of boost?

 

I have the map sensor. So the open loop should be on..,because it's not letting us scale injectors otherwse

 

Ok. It is the Tps. Now we have to get a new one.. On it's way.. And tune... I hope.
But, we need to bring to dealer for master reprogram??? Is there Ny way to do it our selves?

 

Ok. I replaced the Tps and te cr works now but when the utech is plugged in we do not have controll of the throttle. It just idles. We trod calibrating etc... Why is this so hard!
