gsr ecu? 9k red line hmm... sounds like a TypeR. Prolly ctr. Very nice ecu. Is it obd-2a or is it more then likely obd-2b. LMK I'm very interested if it's obd-2a. Also for you people that didn't know the jdm ctr computer acts like an obd-1 ecu. So it doesn't read crank sensor or secondary o2 sensor, etc. ANyways g/l if it's not obd-2a.
