what exactly is a fields vafc? is it as good as an apexi? will it work on a d16y8 vtec motor with 450's?

Sinner

First off. Its not that good. I own one and use it. You cant really use dsm 450's because it wont go below -30 unlike most that will go -50. The only reason I'm using it is because I got it dirt cheap and brand new. I'm using ford probe injectors which are smaller. In other words. You wont be able do tune it as good as most. It also doesnt have high and low throttle which I really wish I had. ... dont get it unless you get it stupid cheap or free.

I ran 450cc dsm injectors with fields v-afc at -30 across board it ran pretty rich but it worked never threw CEL my cars 90 ls integra odb0. If you do a search on fields v-afc Theirs alot of info on it. But it will run 450cc injectors. It will be rich but it will run them.

maybe I didnt say it correctly. I did work with 450cc's just ran stupid rich.

is there anything i can do to lean it out any further? bigger resistors, or do i just have to go with smaller injectors? anyb ideas guys? thanx

I read on HT that a GM 3-BAR MAP sensor would lean it out to like 40% then you can add fuel as needed with the fields, but maybe someone here needs to provide better information.Also it said you can get the map sensor off a 88 model firebird/trans-am

what about a resitor with more resistance. less voltage to injectors equals less fuel right?

Sinner

no I dont think that is correct. They are silnoids. They open and close. giving them resistance will not help. you need to slow them down.
