I was wondering if someone could tell me how you ajust the a/f map in this ecm. I am used to more modern tuning setups where you ajust the a/f table of rpm/kpa to the target a/f and then tune the VE table to meet that target. I see no direct way of tuning the a/f that the O2 sensors are striving for when in closed loop, only pe, ae, temp and other adders or offsets. Do you just change the VE to get the target a/f that you want, keeping track of the a/f yourself? If so what happened when the O2 takes over, or do you just trick it into constant open loop operation. Any help will be appreciated.
