All sounds good, thanks for that. I'm not starting from scratch as the car is tuned prob 95% just trying to clean up drivability myself as it's obviously really expensive to keep paying a tuner for diminishing returns. The fuel tables are set up decent, as is the basic setup.. i think -

LTFT is a useful tool, but always ask yourself why it's correcting first (I.E is it being too aggressive? is it fighting with decel?). Also more importantly, manually smooth out your fuel map afterwards as it will make it ugly and lumpy after applying. -

Not at all, it's there for a reason. Both ST and LT fuel trims are there to be used. Think of a modern EFI stock car, they utilise both ST and LT as well. Of course you want to have the injector data, coolant temp, fuel temp, fuel density, baro, air temp tables all correctly defined with fuel trims against them so your LT and ST aren't working hard to meet the AFR targets. You'll also find that with bigger cams, you might need to target a bit richer than stoich as you'll find it will buckle. I'll send some screen shots of how I set things up (once Lenovo the pricks send back my laptop, been 3x weeks to replace a mobo under warranty). -
The MAP prediction setup looks complex to me, i don't understand any of the 4 pages really 🤷🏻♂️. I'll have to do some research Also, from your experience, should i be afraid of using the LTFT as a means to improve drivability over time?

If you're using an Elite, disable the transient fuel function and use the MAP prediction. It's light years ahead of the transient crap.
