Safc Neo guru.. quik questions

[BoostinByeU]

So on my screen I have a couple of questions about some items i dont know about.
What is the KPA readings it almost corresponds with my boost gauge.

2nd question? my car was tuned not by me. but the Corrections shows 0.0 at normal but during WOT -1.2 - -1.8 really it veries ..is it the fuel its pulling?

kpa is manifold pressure but reading in kpa as opposed to psig

you dont need any correction during normal driving, the ecu will make adjustments +/- 30% while in closed loop

at wot if it is -1.2% it is reducing the map voltage signal to the ecu by 1.2 %

[never2muchboost]

if you dont know how to convert kpa to psig the formula is kpa x 0.145=psi

Thanx, and I love N2MB products!! i got friends with a3's and ms3's sportingyour wot boxes. Getting the boost box after my clutch.

This is only true if you are running the corresponding injectors to the PCM...i.e. S1 with Stock 04/05/S1, S2 with S2/S3, DSP/SCP with rescale for aftermarket injectors. If your running say 750's with the stock PCM, zeroing in your fuel trims makes the car cruise much better.

if hes pulling 1.2% you think he has 750's?
