turbo vafc hack
ok, i put in a set of 440 cc injectors and a did vafc hack to run the injectors. The car starts on the frist try but it idles about to 400 to 500 {which is very low} and when i give it gas it studder to pick. I can't even drive around the block. My setting are all the same on lo/hi and narrow /wide. I have the vafc2 with the black face and the TH-POINT is set at narr. 10% and the wide is 50%. what is the low and high here. Should i set it to 98% low and 99% high???like the older vafc...any help here...
1-2.5k -40% 3k -40% 4k -35% 5k -35% 6k -35% 7k -35% 8k -35% 9k- 35% |

It appears that you maybe to lean. Fiddle with the Narrow low cam and give it a little bit more juice. Set 1000 RPM at about -35% and add more to bring up your idle. 10% and 50% on TH-POINT may also be your problem. Try bringing it up to 72 lo and 73 hi. That is where honda ECU go to close loop. Goodluck...

ive also noticed with mine that sometimes while driving on and off the gas there is a hesitation or a jerk if you want to call it that. im pretty sure this is normal for all AFC hacks.
what are your other settings at? Sensor type, car select... those settings? they make a difference too. |

sivik, change your spark plugs..... also OBD1 ownzzz. Never had that hesitation problem ever since I converted.

i change my plugs like once a month... use NGK 1 step colder than stock. I've thought about converting, whats required other than the ECU? new turbos will smoke due to the seals setting and all the other crap inside burning out. it should go away after a day. if not then you might have an oil leak on the turbo exhaust side, but if its new i highly doubt that. |

OBD1 conversion harness from boomslang ($75 shipped). Get a P28 manual ECU. It so much of a difference man. |

if you've never done it before, i'd also recomend changing your plug wires... not too expensive, you prolly need them, and they help on the acceleration stuttering problem a bit also

If you are still smoke white smoke, check your oil return line. If it is pinched, it will back flow to the turbine outlet side and through your exhaust system........
