ECT.c (+)

What the strange behaviour of ECT.c ? (ECT value nearly constant)
Because "throttle tip" is 10% ?

What the best value "throttle tip" for NA H22A ?

Thanks.

Post the calibration and the datalog so that it can be better examined.

If that was a datalog of a drive, and you started out dataloging with the engine fully warmed up, that is perfectly normal. The engine coolant thermostat is in place to maintain a constant engine temperature, and yours appears to be doing its job rather well.

Actually now that I look at your datalog again, its your IAT (intake air temperature) that is almost completely constant. That is a little unusual, but what's more unusual is the large variations in your coolant (ECT) temps. They should be more constant than that, unless you have a really small window of information selected.

Datalog and calibration

The problem is that your IAT compensation tables start at -40 and go to only 3 degrees F, and your ECT compensation tables start at -40 and only go as high as 19 degrees F. Open a new calibration and compare it to yours.

Thank you very much !

What about throttle tip value ? What you recommend in my case ?

Throttle tip in is somethign you will have to experiment with.
