Greetings, As indiciated by the topic I've got a '00 Si with the GReddy Kit (and the FMIC kit as well) and the CEL comes on when it sees boost. Obviously this is the "P1106: Barometric Pressure (BARO) Sensor Circuit Range/Performance" code that everyone hates. Problem is, the stupid blue box (the FMU, not an e-Manage) is supposed to lie to the ECU about that and it's not. I think. Any one else experience this problem, I hate having to reset the CEL and granny the car to the inspection place every year. It's been doing this for quite some time now (a month or so after the kit when on, 20k miles or so, but I don't drive the car primarly so it never bothered me.) The car runs well, no black smoke out the tail pipe, no weird idles, and good power under boost. To top it off it still does 25mpg or so. Also, if anyone has a scanned copy of the GReddy manual for this kit that shows the wiring to the ECU, it'd be appreiciated since I can't seem to fnd my copy of it. I'm going back to dig for it in the file cabinet from hell. Also, the replys of "throw out the FMU and get a e-Manage, Hondata, Uberdata, AEM EMS, Motec 800, etc..." are not what I'm looking for. This is a bolt on kit, and it's supposed to work. I am going to re-check my wiring on the ECU, as that is most likely my culprit, but I'd like to see if anyone else has experienced this problem. I found a post somewhere on the 'net that someone had the same issue with the GReddy kit, but the site is defunct now. Any help would be appreciated. Thanks in advance.
