Hopefully i posted in the correct section....I have a '91 crx si with a dual cam zc swap. I am using the PM7 ecu. It is throwing code 11 and i can't find a code 11 anywhere. The only mention i've seen is that it is a nonexistent code. It is not a faulty ecu either i have tried a few different ecu's and i get the same 11 error code. I have only found two somewhat related cases....one being someone having a rev limit issue at 3,000 rpm and another case i seen is someone said they shift into reverse and the engine light comes on and runs like crap. I am wondering if it is something to do with the transmission or wiring with the drivetrain.....i was thinking and i have trouble with mine sometimes my car will "chug" or "buck" at exactly 3,000 rpm's and i never could figure it out, i've replaced so many parts and checked and re-checked everything i can think of, and now that i see two other cases of drivetrain related issues i am thinking it may be a wiring issue or something? Anyone have any ideas what the code 11 is or how to fix the "chug" at 3,000 rpms?? Thanks in advance.
