Default MS1: idle after hot restart fixed!

I found a workaround for the hot-idle issue (couldn't get the MAT correction work right, sensor is in the IC cold-side end tank), I cranked the fuel in the idle cells way up so that it idles correct after a hot-start (110 - 120F MAT), then use EGO with a wide range (20%) to correct it.
This way I get good (14:1) idle under normal conditions and stable idle after hot-restart.
EGO alone with "normal" VE took too long to up the fuel after hot-restart
because of the warm-up time of the Wideband O2 but starting out rich and use EGO to lean-out under normal conditions works pretty well.

I'll have to try this. Thanks a lot! It should work the same on pnp right? When I start my car hot it barely wants to idle until it "figures" itself out again.
Can you post a picture of your ego controls?

Nothing special in the EGO settings, I just increased the authority from 10% to 20%.
I increased the VE in the idle area from around 43 to around 50.
