ok so i hooked my vafc up today n after we worked some kinks out we got the car to run right. Well i drove around for awhile 3 hours and it was fine and then as i was getting on the interstate i accelerated and the car threw a check engine light and would no longer accelerate after 5k and it was shuddering and popping real bad what would cause this ?? i returned the setting back to normal and its still doing the same thing. i cant check the light tonight but any idea what could cause this??

 

1) why are u running a vafc on a 4g63
2) how is this an event?

 

damn i meant for it to go in tech talk shit.
but i dont have a 4g63 nemore i have a 99 civic ex c
can i get a mod to move it im tired and frustrated and just clicked the wrong section sorry for the troubles though.

 

wat motor?

 

What year civic?

It could be in limp mode or you really messed something up.

Hopefully you didn't tune it yourself and thought it was ok.

 

Which generation VAFC is this? Are you running the AFC "hack", meaning... are you turboed? If not, do the easiest way out first.
1. "initialize" it to go back on default.
2. check make sure you are on "4-up arrow"
3. select "6 in, 6 out"

Also, what size injectors are you using?

 

everything is stock no turbo its a d16y8. im thinking its in limp mode imma reset the ecu today and see what happens

 

Then the quickest way to fix it is to go back on "default". Then you should try what I just recommended. Also, again, which version VAFC is this?

 

sorry im not sure what version it is its silver blue screen so im guessin v.1

 

probably a code 13 if you bypassed the map sensor, that will throw it in limp mode....



Edit- maybe not code 13 if you're no boosted....
