Yea those are the stock tables. My setup is still stock from the TB on so they work well. I suppose it'd make more sense to change them if you had a different IM, hondata style gasket, or displaced the IAT sensor.

Re: How to tune IAT and ECT
What is you had a nice gas pedal compressor Or stuck feller gauges on the throttle body cam and held the motor at a steady spot in the map lets say 1500 and 634 mbar. So now your motor is at a steady state and the iac is not interfering with things. Then you let it cool full then you started it up and watched you afrs and ect. Then tune to whatever you want. I agree iat should be close to universal. But I think this idea will work good with ect enrichment.
I don’t know? LOL this is all not moving. Do this on a cold day and a hot day for iat
Do you have a big variation from cold to hot days or something?
