Bank 1 & bank 2 lean after airflow & feet forward changes on whipple build

[MichaelGardinier]

I have been dialing in drivability on my 426, 2.9 whipple build. One of the main things I have been dialing in is the transition into boost and also staying out of boost when it's not desired. To do this I have scaled my large throttle tables under feet forward control, the cars feels damn near NA until I really lean into the pedal now and drives so smooth and goes into boost with a factory like feel.

For the Throttle Body Model I simply added 28ish percent from top to bottom as that roughly the difference from the stock TB to the 102mm I run.

However sense doing this I often get a "bank 1 and 2 lean" my assumption is because I have more air entering the car and the pedal not reflecting it? I would honestly rather turn the codes off then go back to the old tables, but wanted Input from others. Anything else to check out?

Sensed MAP on or off?

[MichaelGardinier]

Off

[spoolboy]

Off

Turn it on.

Turn it on.

Not a good idea on the NGC3. Unlike the GPEC, in my experience no matter what you do, you will exceed a hard coded airflow limit based on actual Map readings if you leave it enabled. The result is a completely dead gas pedal, car coasting in limp mode half way through a pull. Have to decelerate under 20mph or key off/key on to reset it. Not a fun time.

Thank you for correcting me on that.

What conditions have led to this? Is this something you only see in boosted applications? I only ask because I have Sensed MAP enabled on my '06 JGC SRT-8 that uses NGC3 CAN, and haven't had any issues with it. But it is an N/A 426 application.
