Average WB AFR in 5800-6199 range for the all run in 100 TPS : 13.8 (2.557@6000)
No other run for this weekend
First, i dont anderstand how hptuner calc %INJ Duty only with msec INJ. Pulse Width Avg on Bank ??? (stock i'm with 26lbs, with A&A kit i'm with 60lbs, but HPT scanner dont know this !)
Second, i cant be able to min my 12.62 afr for 5400-5799rmp range, 12.62 with 1.51 PE... and 12.7 with 1.681 PE, look like i need change 60 injectors for bigger, or need upgrade fuel system (remember, it's a 2000 corvette, i have just put 255lbs legenfilter fuel pomp), or stop use E85 ! ???
What do you think about that ?
