DE-t b13 issue's
92 b13, JWT 370cc, t25

Recently installed the turbo to my DE. The ecu is tuned for 3bar fuel and it runs boggish under 3k. Recently hooked up afc it runs alot better but when I get on it rpm idle jumps up to 3k plus. Also smokes when downshift or in neutral at a stop. Can anyone guide me on how to tune the neoafc. No wideband gauge also

What color smoke are you talking - White, Blue, Black ???

White smoke. It's from to much fuel I'm guessing

get a wideband

White smoke would be coolant leaking into combustion chamber - possible head gasket.

Have you done a compression or block test?

Does it bog all the time under 3k or only when cold?

What MAF?

Verified no leaking between MAF - Turbo - I/C - TB - I/M ?

Compression test no. Need to though. And yea like everytime! And when it's cold it'll die out tel it's warm. & stock maf but the ecu is tuned for stock maf. I just don't understand mostly why when I get on it the idle jumps up from anywhere to 2k and up.

And when it's good the idle jumps from 1k to 2k then drops but I think the idle screw will fix it

That's what's next a wideband! I'm lookin for one to buy I'm sure that it will help alot

The idle jumping could be O2 - but the white smoke, well that's never good. Check to make sure your coolant level is not dropping either.
