Hondata

Hi Guys , I have a problem with a GM 3 map sensor , when I started to tune the car , I took the MSD 3 bar map scaler but when in decel I always had a check engine light , so I switch for a Motec scaler , my AFR with the MSD scaler was around 14 at idle in open loop , with the Motec scaler it is now around 11.5 , even if I<m removing -30% no change in my AFR , it is stuck at 11.5 , does somebody can help me with that .

Thank you

its reading wrong vaccum. scalar and offset are wrong. gm 3 bars have a few different versions floating around. throw it in the trash and get a hondata 4bar.
