All fueling maps of this combination on the same post [screenshot for posterity]?
Of course, hadn't been on my laptop...
This strategy is for
91 oct, keep in mind this is on a car with a vertical FMIC, no fans, at 6000 feet ambient and often being driven/tested very hard at 7500 plus feet (about 10,200 max) and 7500 rpm at 22-29 psi. My biggest issue up here is the deformation of boost hoses at high AITs for long duration after heat soaking the car while sitting, i consider this fueling conservative. For race gas you can run way less fuel, with meth injection you don't need to think about afrs ever really in regards to the tune, just hoses prey meth nozzle. With nitrous you don't need to worry about afrs just fuel. This is a daily driver who knows what I might get for fuel and no frills or power adders/helps sort of system that works extremely well. With even something like c16 this would still be a monster file as you wouldn't see knock. i have tested this with q16 and e85 but run out of fuel on the corn, going to re-vist e85 tuning this summer when its easier to buy. If i ran meth injection I would basically always run a race style strategy.

I try and dump a little fuel on hammer down with the
lamfa, nothing much, we are talking race gas short run afrs here just to start the process of cooling the charge before boost starts ramping the line pressures. On my BT car if I punch it bellow boost threshold it does indeed just
dump useless fuel but not enough to
stop building tq/boost. just punishes me a little for driving lazy. Above boost threshold its dumping it down to
optimal tq afr before krl or bts can have a say as it is able to jump immediately back into boost.
On boost krl is being used with tonys kr map, it is pretty broad and works well with basically any setup since load is load. I have krl running high 11s in
the 0 row for no knock and this has been fantastic, this is the
theoretical peak power afr for a 2.7t under boost. I quickly drop through the range and settle at 8 cfs to 11.1 afr which is where the f
lame front and tq are all but dropping away and this
stops detonation. Since setting this up my car has never logged more than 8-9 cf and only for a short duration, it always recovers very quickly and gets out of det and just rides the line pulling hard and clean with minimal knock that cannot be avoided with 91 but settling in around 3-4 cfs and a nice powerful afr.
Then for when I just cant seem to run out of road which is sort of rare or i am abusing the car with brake boosting and the like I have BTS coming on late (
assuming my/your maf stuff and calc ect/load is right, if it is scaled low you will not have the safety net at all especially with no real egts, too high and it defeats the purpose and robs power) to cool it all down, sort of like the egt trigger. I have no cats and high end components/turbo/manifold so I let it get hot. It dumps the afr below the usable flame speed range and just wastes fuel for the sole purpose of shutting down power without literally shutting down the engine like with other interventions like throttle cut. I max my normal fuel system around 7.5:1 afr so there is decent head room here for me.
whew... long but hopefully helpful, bold and italics are meant to be helpful for points to focus on and not to seem pretentious.
Adapting any of these or all of them to another car is really easy, just base it all off your boost profile, hot side components like cats and your fuel / fuel system.
