I got a H22a witha MUGEN chipped p28 with a VAFC2 dyno tuned
everything was fine and dandy with the idle at start was 700-800 rpms
everything was good till today my car was all warmed up and its sitting at 1500 rpms at idle

ive had no problem with the idle for a week now since i got the ecu in i even tried unplugging it anyone else have a mugen chipped p28 with there h22s?

 

Is it the ebay chip?

 

nope

 

Was it dyno tuned when you put the VAFC in? Who did the dyno tuning? I would ask them what it might be.

I have a VAFC in the mail. I was going to put it on my lude with a harness so I can take it off if I dont like it. I'm interested to hear what went wrong

 

Check engine light?

my best bet is FITV

 

well heres the wierd thing
i put in the p28 ecu 4 months ago and same thing happened 4 days after the car started to idle really high round 1500

now that i got it back in with the VAFC2 its doign the same thing like i said 4 days after

its not that big of a deal i just wanna know why

 

That is wierd. I'm sorry I cannot offer any advice to your problem, but I am curious. I just recieved a VAFC2 in the mail today. I have been debating putting it in my car. Do you like the VAFC2? Noticeable differance?

 

i used it for my turbo im converting to hondata uberdata or crome soon
lota people are against it but with big injectors, fpr, and walboro pump you should be safe runnin 6psi

depending on your mods you will notice slight differences

 

check your coolant. sometimes the fast idle valve gets stuck when there is no coolant in the valve

 

im going to tune it with crome on friday hopefully it will be fixed then
