we were out tuning last night and all was well with the FAST until we stopped for about 2 hours. we got back in the car and after about 10 min or driving the FAST ve table stopped reading boost. the little green ball just fell to the bottom of the grid and sat there only moving up and down with RPM not with boost. the MAP readings on the dash were good but not the dash in the VE window. so below 2000rpm before the wideband correction would kick in the car went all stupid lean. above 2000 the O2 was only having to correct small amounts under boost. it looks like the ECU was still following the proper tune but the FAST was not showing it. the green indicators just slides back and forth on the very bottom. anyone have any ideas?
