I thought I didn’t take any pictures at all since it was just myself and Toma that day. Pretty hectic since it’s more than just a re-tune. The change is from Uberdata to Hondata S200 with a 3bar map sensor.
A lot of things can go wrong and I don’t like just good enough. A lot of folks I don’t get how they are willing to spend dyno time on fixing the car. With that in mind I also bring tools or things that I think I may need. I treat this as if I am going to a race.
Nothing ends the day when you find out your missing that one little part or that part failed…. That over preparedness paid off as gave Toma pointed out – “Your the only guy I know that brings their own extension cord”. A bit over prepared but we used it to power the fan
It was pretty painless until we turned on the O2 sensor to close loop and then things just went crazy.
Things I have ruled out:
- New MAP sensor – also tested before
- Hondata –> Reload new B18B / RS map
- Tested and did a street tune before
- Ran a base run – ECU seems to respond
- Apexi – could be set improperly
- Good thing Rage2 wasn’t busy when I called so the settings are ok
In the end we found a tiny exhaust leak right underneath the turbo down pipe flange.
So, we stopped at 240whp with the O2 Sensor in open loop until I fix the leak.
