Well, in it's normal form, the Z's ecu switches from the 'Cold' fuel and timing tables when the oil temp breaks a barrier. It's around 80c I believe. It has hysteresis, so it doesn't switch BACK to the cold tables just because oil temp drops below that threshold unless the oil temp drops very very low.

That said, there is a point during warm up where the ECU interpolates as best it can between the COLD and MAIN tables until that threshold is broken. I don't know what that point where the interpolation begins is, however.


This is just info from the guys @ Uprev on the behavior of the stock ECU. It may not apply at all to a 'Race Rom' flashed ECU, I don't know.

My only point was, as long as it has come up to ~180 degrees, it's irrelevant to this discussion (as long as it isn't overheated of course).
