I see that Turbo XS recommends 0 psi for use as the MAP threshhold value for open loop fuel control. What do you use? What turboxs recommends makes sense, but is setting it to 1psi (for example) give you better drivability and/or transition between ECU closed loop control and the UTEC open loop control?

 

Bueller?? Bueller? anyone out there????

I am curious as to what pressure(or vaccum) you set the MAP threshhold on your UTEC. even though turboxs recommends 0 psi, i can see some advantages to letting the stock ECu still handle things up to 1 or maybe 2 psi.

any thoughts?

 

i have mine set at 3 and 20, for your car i was thinking 2 or 3 for the lower numbers

after doing research on it, most people have 2 to 3 with no problems...


are you running the wastegate springs to control the boost?? i dont think we ever talked about that??

 

We usually set the threshold at 1psi, and 2500rpm. I like to have full control over fuel as soon as the boost kicks in. With additional road and dyno tuning, there is zero hesitation, and no sensation as to when the UTEC actually kicks in. It's seamless to the driver.
