Hi guys. i been trying and trying to tune and adjust my vafc right but just cant get it running right maybe you guys can help me. everytime i give it some gas the check engine light keeps turning on. the codes are 3 and 7.

here is what i got maybe this will you you guys helping me adjust it;

jdm b16a motor
intake
ctr cam shafts
type r headers 2 1/4 in exhuast with text pipe
stock p30 ecu.

motor is mainly stock.

 

get rid of the vafc and get ecu tune, hondata, crome. to name a few.

 

Like dude above me said, its not the ideal way to tune a car, but you just need to use a wideband and adjust the a/f ratios accordingly. You do not need to change vtec engagement points

 

so i can just run it stock without the vafc? and go another route? how would you get the ecu tuned? getting it chipped?

 

for a ecu tune get a p72 ecu i belive with a chip and have it tunned by a tunner that is qualified to tune it. or just find a reputable tuner and just ask him what you really need. each tuner has thier own tuning method.

 

You need to get your ecu chipped, and get crome. Or purchase hondata, then find yourself a knowledgable tuner. To tune it for ya, but get some more mods done first.

 

thanks for the advice guys. maybe ill go a different route. what do you guys think would be a good street setup? im not really trying to go all out.

 

i really dont think you would need a tune for that kind of set up...if u had good headwork, big(ger) cams, injectors you would really need a tune but with that kind of set up you should be running fine...especially with the p30 ecu

CEL #3 is ur MAP sensor and #7 is ur TPS sensor have u reset ur ecu? and then tried running it and seeing if the CEL's come back up?

 

Based on those particular codes I wonder if the MAP and TPS connectors or switched, certainly wouldn't be the first time its happened.
