Hello everyone,

I'm working on 9 sand buggys (purpose rental). The PCM is a P11. Engine 2.2 ecotec(from i suppose a chevrolet cavalier 2004)
Purchased all the licences needed to tune the 9 of them. Using a Flashscan V2.

My question/trouble is the following :

1 - I have set up the ON and OFF temp for the electrical fan... low speed ON : 92, low speed OFF : 90. That works perfectly.
But... there is always a but... some times, cars stopped, the fan goes on at 88... Why?

2 - There is still one O2 sensor, but i cant see anywhere in the mapping if in closed loop or not? is it possible?

I know it's old stuff and surely very easy tuning for you guys, but some help would be much appreciated...

Thanks

Steven
