Since I have Bank 1 really dialed in, I moved my wideband over to bank 2 and started logging.
Closed loop looked very good...much like bank 1, which was no shock.
However, open loop WOT fueling was a good bit richer than bank 2.
I tune bank 1 for 0.87 Lambda, which is 12.4 AFR using E7 fuel.
Bank 2 was running around 0.83 Lambda, which is 11.9 AFR.
I wasn't shocked at the difference, but I did find that any changes to the Bank 2 VE table did nothing.
I enabled Bank 2 before I even started, but it appears the switch doesn't work in the tune.
Is there anything HP Tuners can do to get this working? I leaned Bank 1 by 1% to bring Bank 2 to around 0.84, but I really want to get them both at 0.87.
I suspect some of my Bank 2 ST KNK is the car being slightly to rich.
