S200 boost problems

I installed my s200 and am running a base map until i have it tunned. My problem is if im WOT for about 3 seconds the fuel is cut and the check engine light goes on and the s200 light turns off. I only have this problem at WOT. If i run at 85% throttle its fine. both times the boost is about 5 PSI so i am not hitting the boost cut. Anyone have any ideas?

There could be several reasons for this to happen. Did you burn the program yourself?

Yes i burnt the programs myself. My setup is similar to a d16z6 greddy turbo so i had tryed using the greddy tune that came with the rom editor, and i also tryed creating a new map with the wizard. They both ran good with no boost and in boost it was hessitation a bit, seemed like to much fuel, but both gave me this problem when it was WOT. I am also using the romulator right now, but that shouldnt make a difference.

Maybe there is something wrong with the program you burned. Something that you might have missed. How much is the boost? You can e-mail me the bin file and I'll check if you forgot to check some stuff.

Please include what you installed in the car.

First you gotta know what error code you are getting. In the Hondalogger there is an error code tab which you can read when a CEL is reported.

You could possibly be running way too rich or way too lean. My Hunch is very very rich...

Get the error code first. Looks like there is nothing wrong with the basemap except the fuel and ignition values.

It does not show any error codes when this happens. Did you look at the datalogging errors on the recording i send you? Is it normal to have that many errors?

The error code won't show during playback. You have to ask somebody to take a look at the error tab while it is actually happening.

If there is really no error code then you could be running in a tuning problem. That is my only guess. The reason the CEL turns on I think is that the engine temporily shutdown but since you are moving it jumpstarts itself.

I think i figuered out what was wrong. I had build a 1.2ghz computer into the dash of my car with an lcd display on the dash so i wouldnt have to always bring a laptop with me for tunning and datalogging, and i had put the hondata box next to the motherboard. There must have been some interference or something because i moved the hondata box somewhere else and it works fine now. It still shuts down sometimes past 5psi but i think this is just a tunning problem. I held the wastegate open so there was no boost and everything worked good. Thanks for the help QUICKSILVER.
