I was autotuning my turbo miata and the autotuner was maxing out the fuel on the upper cells at 255.I updated the required fuel, deadtimes and everything for my 640cc flowforce injectors which is why i was autotuning in the first place.
I was thinking maybe it's my fuel pump but i hear it prime and when i change the required fuel to a higher number and rescale the ve table it seems to be better and have a normal amount of fuel. You can roast my VE Table too but its a little wonky because I have an open downpipe with the wideband at the end so i have to manually lean out some lower rpm spots since the wideband thinks im lean when it touches the atmospheric air.

Don't run an open downpipe so your wideband reports the correct AFR so autotune can work properly?

Didn't open tune, turn on incorporate AFR target

Edit: didn't notice open downpipe detail.

main reason i have open downpipe is PO had a shitty side dump exhaust that was all welded as one piece so I'm getting an exhaust made. It'll still be a week or so though.

I suspect you will be able to tune fuel correctly once the exhaust exit is a bit further from the O2 sensor, would recommend holding off on tuning until then, will lead to you using way too much fuel everywhere

set your VE multiplier to fixed instead of baro or setup your baro sensor if you have one.
