If I don't time it just right, nice little fireball pops down the exhaust).
Are you saying you corrected your lean spots in that same A:F table, or elsewhere?

Can i trouble you to post up a screenshot of your A:F tables please? (either current or the backfiring one). How bad was the backfire? I dont mind a little crackle and pop
Thankyou for your time and effort in researching and refining something for the community to use. Likewise for Baer.
I've got both maps loaded at the moment and although i tried to tell myself to like Baer's one more because it is an 'upgrade' over wstar's (by no means inferior) and it reduced some of the low rpm lag for him. On tip in it actually felt worse. For example, parking the car using my normal light taps of the gas pedal and feathering the clutch almost resulted in stalling. I am running an underdriven crank pulley so that might be a factor too. During normal driving, Baer's map for me was noticeably more jerky. I thought a map designed for 7AT would feel weird on a 6MT, and a map designed for 6MT would be better for my car.
One thing i would like to note is that SRM for me while using wstar's map works much better than it ever has on my car!! I always thought the SRM feature on my car was a bit off compared to the numerous test drives i had before buying this one. It works so well that i even get a smooth engine braking action when going down gears. With Baer's map, i got a lot of jerky shifts - mainly upshifts though. Downshifting was not much different from stock. I dont think it's a coincidence because when switch between maps on the fly, the effect is instantly noticeable.
Again, i'm not saying either map is superior/inferior. For my driving style and personal preferences, wstar's map is my choice. I didnt have a chance to test out both maps at higher rpm (4000+).
