Hondata

Wait this could be an issue as the vehicle is setup for map tuning only. No maf

Should I just flash a stock cal into it or unmarry the interface?

I noticed that my issue only happens in open loop when cold. First start / anymore thoughts? If you need a newlog let me know.

I’ll check if the intake manifold thermal gasket has a leak would be really strange that this just showed up there. I have checked all hoses and with the stock throttle body and it’s thermal gasket re-tightened not finding any leaks.

ok thanks will try it and let you know.

Will do, the factory o2 sensor has nit been removed or diabled. Just trying to get the wideband to report.
