Your indicator is in the dash cluster, right? Since the US cars have their overheat indicator next to the ashtray (and it's wired differently) that function doesn't work for us unless you do some re-wiring.

My recollection is that it would flash on excessive knock.

Hwl Flashing in power fc commander, in "sensor check"

I was thinking i've exceed the capacity of oem boost sensor, since pfc commander read more than 0.87 BAR (depends gear)

No, the oem boost sensor is good for 1.2 bar or so. You need to go to the sensor screen and see what is out of spec.

A lot of poeple switch to a GM map sensor during PFC install due to the stock map sensor giving unaccurate readings to the computer

rynberg

The stock MAP sensor does NOT give inaccurate readings. Where the hell did you come up with that idea?

Dave Newbern is right with the opinion the flashes shows the excessive Knockreadings.And Dave also in Europe the Indicator for Exhaust overheating is in the Lokation near of the ashtray.
