Need help... Boost problems...
Hey guys.. I've been boosted for about 1 1/2 now.. My car has been tuned and i'm running a hondata S200b with a p28 ecu... The problem i'm having is when I start to go into boost my check engine light comes on and the car just hits a rev limiter like.. Soon as I let off the gas the light goes off and the car runs fine until it's under a load and it starts to go into boost... Can anyone point me into a direction to start looking for the problem.. Any help would be greatly appreciated...

Any chance that it could be a bad map sensor?? It's only when it starts to see boost it goes into limp mode..

MAP sensor? what amount of boost are you running? have you done anything to make the MAP happy under boost? or does the S200 cut the signal so the ECU never sees positive pressure? What code is it giving you? thats a good start!

Re: Need help... Boost problems... (2000psi)
I was told on the Hondata as long as you don't boost over 10psi that you don't need to do anything with the map sensor... I'm only boosting 8psi... Now i'm unable to boost anything.. lol... Could a bad O2 sensor cause the car to do this?? I'm running a hondata s200b w/p28 ecu.. Or I'm thinking a bad ecu or something happen to the EPROM chip... Dunno know yet.... I don't think i'm able to pull the code because the cel light doesn't stay on.. It goes off after I let off full throttle...

It sounds like the boost option isnt enabled. </TD></TR></TABLE>The car has been boosting and has been tuned before... This problem just started happening... A lot of ppl are saying it sounds like the hondata boost option isn't working... I call Hondata which was kinda worthless.. They told me that I would need to take it to my closest dealer to have it checked out.. I'm from Pittsburgh, PA and probably the closest Hondata dealer is Columbus which isn't bad "2 hrs" but it's not where I took it to get tuned "Payntechnologies" in Michigan.. I don't feel comfortable driving 5 hrs to have someone look at the hardware and say yep the hondata box is bad... I was hoping to send my Hondata/ecu somewhere and have it check out to see where the problem is but thats not looking like an option....
