Idle issue on Vems.

[Billman]

set the lower left position all to 12 and let VEMS idle ignition control sort the rest. See that your fuel is also the same at this region and then let the EGO correction do minor corrections. Also check that the MAT enrichment is correct in this region.

Thank you Billman

do you believe Pop and me didn't set patch for Air Temp Sensor
So we used wrong MAT (21-22)

We will learn to set idel again

[Billman]

What iat sensor do you use?

[popdemonic]

we're currently sticking with stock I5 IAT sensor Billman since it requires some grinding job at least on the 1,8T IAT housing to fit it back to stock place.
personally,i don't know how sensitive the 1,8T IAT sensor is but from what i had a look on logs with stock IAT sensor.i'd say it's not that bad as well.

[Billman]

1.8t is much better.

You need to remove an SMD from inside VEMS for that.
