Hey Guys,

Searched but didn't find what i was looking for.

I'm going to be using my Utec to tune my APS TT kit. I have the Map Switch and Map Sensor for boost, what else do i need? What will the boost go up to without the Unichip boost control? What are the actuator springs set to? 8psi? I'm just asking because i have my Tune set up for Thursday and i don't wanna over boost my car. Any help would be greatly appreciated. Thank you.

 

The UTEC has a built in boost controller like the Unichip, so you can set it to run min boost at the beginning of the tuning session though the UTEC.

Other then that, you shouldn't need anything else, besides a little attention to the crank angle sensor. The Unichip uses a shielded cable going directly to the unit. What I did was cut the crank angle wire up near the Unichip and then I spliced it in to the crank angle wire going to the ECU. This keeps the shielded wire running to the crank angle, in case that is needed. If you don't want to keep the shielded cable you should be able to just switch the plugs at the crank angle sensor and remove the shielded one from the car.

 

the kit will only boost around 9.5 to 12 psi depending on which exhaust you have. i wouldnt worry too much..

 

The stock actuators will produce 6.5psi of boost pressure with a 2.5 inch exhaust system. once you add the boost control solenoid, you can raise it up from there.

If you are running a 3.5 downpipe, and 3 inch exhaust, you will see roughly 8psi base boost pressure.

Looks like you have everything else you need.

 

I went with a manual boost controller just so i can make sure i can control boost until i can get the Utec to control boost or an electronic boost controller

 

who is doing your tuning in Colorado?

Well we got the Utec to control boost! Had to switch the UNichip boost solenoid out for a Perrin 3 port. Works great!
