AFR WOT running issues

Hi,

Currently working on a TTS supercharged FN2 which had a poor tune with 300+ knock counts and only 259 BHP

I loaded the base supercharged calibration from the Flashpro database and tested and logged and instantly hit 306 BHP BUT AFR once over 30/40 % throttle, it will hit 10.14 AFR and stay there. It will not budge and of course there are recommended % adjustments on the fuel table which when even adjusted as requested, nothing will change and the same recommended % adjustments are present when tested and logged again.

If someone could help me out with this that would be great. I have attached the calibration and log.

The injector dead times are stock but you have 800cc injectors. I'd start there.
Then you need to tune the fuel tables. The lambda will respond to change but you look like a long way off - 50% or so.

I have tuned a lot of TTS kits - please contact me if you are interested on a e-tune. (its not free of charge)
