2004 honda civic EX, only modification is cold air intake tune is stock.

ECU was bench tested by hondata a few months ago and tested good.

S/N on the ECU is 05004244

My D17 wont rev above 3000RPM. I don't think this is a ECU issue... but cannot figure out why. No CEL. Sorry the file is 20 minutes long. If anyone sees any issues as to why please comment. Thank You. Eric

I hope this is the Cal data you need (I feel computer illiterate)

Hopefully this is what you need.

Voltage on connector A pin 6, it does change if you press the throttle.

Yes wires are moved per the set up on the website

I have verified the there is good continuity from the O2 sensor to the ECU as well as voltage from the O2 sensor. Car obviously runs poor as the A/F does not ...
