But I believe that the WOT maps are not 02 sensor driven and only based on the original fuel maps + or - a little "global" adaptation.... I think that this is the situation. On OBD1, WOT was based solely on 02 sensor readings. Worse comes to worse, I will reset to original maps every week. Also I will run the car on the dyno every week after the injectors to see if there really is a measurable amount of adaptation.
I ran the car on the dyno and as AA expected... I was lean... for a turbo at 14-13:1. Actually a little scary. I want to get the mixture down a little.
My boost sensitive fuel regulator is not adding enough pressure. I have considered going to a BEGI adjustable boost regulator but i want to try the injectors. I think that I would be reaching the maximum of the fuel pressure and the fuel pump with me now running 8 psi.
Somebody has to experiment. :^)
The guys at AA says that they are now almost ready to offer a turbo for the OBD2. (Their previous systems were OBD2 to OBD1 conversion) I think either they or Jim C finally cracked the adaptation problem.
