Turbo an F22 with automatic?

Exactly. The ECU tune is more complicated with an auto. Most ECU tuners I know of on this forum would rather not work with automatics. I don't know the details, but i know that much. I DO know of one or two boosted automatics on here, though... so it is certainly possible. blazen_accord is making about 400whp with a boosted H22 automatic.

Yeah blazen_accord was using a t3 t4 turbo before he upgrading turbo's. Last time I talk to him he was boosting 8psi and it jumps up to 12psi when v-tec kicks in. He can can probably really give you and your friend.

One headache of tuning an auto is tuning it for the auto upshift with full throttle runing since auto does not need to let off the gas to shift. There is a huge surge in power, rpm drop, injector/ignition timing, a/f ratio need to be set during those auto upshift and auto kickdown downshift. If they are not tune properly and just flooded with fuel runing rich you will lose a lot of power when it auto shift for you. Off course you can manually shift the auto but the TCU and ECU still does all the calculation.

One idea i thought would be cool is set the ecu to on only engage turbo when the tranny is in sports mode, cause i think the gears run longer then and that would be perfect for turbo (also kind of stealth lol). But yeah no doubt its easier to tune on manual. One thing though, aren't the gears shorter on a h22 auto trans? I know they're shorter with the manual, i could only imagine with auto. How does it feel with turbo?

Do you understand how a turbo works? You can't exactly disengage it...

Sport mode doesn't make the gears any longer, it just stays in gear. Autos keep the turbo under load, so the issue of falling out of boost as you shift isn't present... so gearing isn't as important.

I've heard that tuning an auto is difficult, but I've never done so myself. Tuning is very important when it comes to a turbo motor.

I wend over this a little while ago whe I was thinking of boosting my wagon.

You CAN use a chipped ECU, but not all the programs are going to participate... As fas as Ive heard (from the guy I was going to get to do the tuning) Crome was a no go ... I think he said we had to use Neptune and that he has used it with sucsess on a Prelude (auto turbo) No CEL nothing.

Il see if I can talk to him again to confirm which program was the one that works.
