as the above. it seems my bin has realatively small values for AE/TPS/MAP. earlier this summer before the WB02 install they were stupid rich. 2.5X stock! i falsely assumed the "stumble" was due to inrush of air into comustion chamber on hard accelleration. well i find out i am invoking a 8.8/1 or so A/F in ae and mostly in ae/map. the innovate actually shows a double spike rich first being tps and second the map. now i am thinking if my bpw width is referenced to cid/injector size/fuel pressure(11.5 lbs) and may have no bearing on the AE usec? is this so? i thought i saw that posted? that would suggest 90 lbs injectors with AE tables based on stock 65 lbs may be the problem. is this a possibility?. obviously i will drop AE another 5% accross the board and log some more.

 

Correct, BPW constant has no affect on AE. If the WB is still showing the 8.8:1 AFR during AE I would pull a lot more then 5%. Maybe even cut the AE in half.

The 8.8:1 AFR is absolutely at the limits of the sensor. The AE may even be richer then that.
