Default Tuning VAFC

Hi. I have a 1994 civic dx d15b7 running a rhb5 8psi with 450s and a vafc. I set the wide and narrow throttle all the way across at -35. When I run the car I am getting alot of blue smoke and the air/fuel gauge is reading rich all the time. Does anyone know what I should set my VAfc at. Wich settings should I use all the time? Is anyone using the same engine and turbo that can tell me your settings? Thanks..

Did you try leaning it out a little?

You're not going to get a "perfect" tune with that AFC and you're not going to just use somebody elses settings and get anywhere near good results.
I'm not going to suggest leaning it out because I don't want to be resposible for your motor if it blows so it's all on you.

Blue smoke is bad (oil). Never depend on your shitty narrowband A/F guage either.

Get a wideband or take it to someone who can help you tune it with a wideband.

Read the FAQ too.
