Check engine light... which friggin code it is?
First off, no I'm not retarded. Not today anyways. I know how to check ecu codes just fine. Here's what I posted on H-T (I hate that place but I am desperate right now)
"So I am running a chipped P28 with uberdata. Last night everything was fine, no check engine lights, had my LM-1 outputting to my ecu for datalogging. I come back this morning and I get an error code... except I'm not sure which. There are 2 long blinks followed by a very short one, it's so quick that the bulb doesn't even have time to light up all the way. So I'm thinking code 2, code 20, maybe code 21. I have checked all those out. It's not my O2 sensor, I have closed loop disabled and tried disabling the heater and leaving it on. What the heck could be causing the check engine light?"
Someone suggested code 21 but I have no vtec and all related sensors are disabled. I am kind of confused why the third blink is so damn short. Like a fraction of a second. Anybody have any ideas?

Well I'd have to see for sure but from what your describing, 2 long blinks and 1 short, would be a code 21. That also stands for Vtec spool solenoid valve. I'm not sure why it's throwing that code if your not running a Vtec basemap.

How long are the long blinks supposed to be? I was thinking it could be code 2... with some crazy nanosecond light after it for some reason. But there is nothing wrong with my O2 sensor. My stock one is still installed and was working fine last night. I tried disabling O2 heater (which I shouldn't even have to do) and no luck. arghhhhhhhh!!!!!111111111111
Any input is appreciated.
