- 2002 Civic D17A2
- Stage 2 Crower Cam, Fully Built Head, I/H/E
- K Pro S/N 13885
- ECU P/N - 37820-PND-A07 S/N - 2062-802775
- K Manager version, not updated, which ever came with the system
- Calibration - see attachment
- Datalog - see attachment

I just completely rebuilt my engine, fully built stage 2 head and all new OE pistons rods and so forth every where else. On initial start up, using the calibration that almost matches my mods and car, the engine is running rough see attachments for calibration and datalog. what i would like to know is it safe to let the engine run and reach operating temp the way its currently running....

I also an not running a second 02 sensor untill i get the car running well enough to bring it down the street and get the new cat welded in, until then no second 02 and im running and open down pipe...

It is running very rich. I would put a wideband on it and check mixture before running any more so that you don't wash down the bores.
