Rb25Det Neo, Nistune And A/c

[Alexey Ufa]

Hello!

First sorry for my English!

I've already broke my mind with A/C idle and drive...

With RB25DET NEO when I push my A/C on, the AAC valve opens more (also additional valve starts pulsing vaccum), the MAF voltage become higher too, but injection time remains near... The A/C compressor and fan are working, all the systems exept fuel (of course additional) work great!

So, my idle with A/C rise just a lot (only about 50-70 RPMs higher) and the AFR is too high - about 16-17.

Also when I start driving, there a lack of power and AFR is about 18-20 (till about 3000 RPMs, after car goes much better). And when I push A/C off, the car goes great and AFR is 14-15 on slow motion.

What can be wrong? Why there isn't enought fuel with A/C? And how can I add some fuel with A/C on?

Thank's!
