9653 Decel fuel cut resume table
Just switched one of my cars over to SD in preparation for having my tuner go through it. I've been driving it around to work out any potential bugs for him and this car has a light weight clutch/flywheel and has never wanted to catch idle with the A/C on, occasional stall with the A/C off, but if you decel until fuel cut turns off it has no issues. I've done a few things for anti-stall prevention in the tune like bumping timing below target idle and adjusting IAC steps, but it hates the A/C on. I have another car in a similar situation, I'd like to get both to at least cruise without having to play footloose on the pedals when coming to a stop and I've solved this in some of my standalone cars by enabling fuel cut resume at a higher RPM. I went looking for this table and found what was labeled as the 9653 definition, but after flashing in some changes I've solved the stall issue, but created an issue where the car will not go into boost at all. I'm assuming this isn't the correct definition or it's controlling more than just fuel cut resume for some reason, but was hoping someone can confirm/deny this is correct. I did flash back to the original tune to verify it's something in the tune and not a coincidental mechanical issue and it definitely is the tune. Whatever its controlling seems to be fuel related as I logged timing and it's not effected. The car sounds like it's trying to go into the launch control map as you reach boost. I don't have a permanent wideband installed in this car so I can't currently see what AFR's are doing which is why I just logged timing to see if it was pulling it way down and it's not. This is the current definition I have and I dont seem to see any others listed for a 9653 rom, thanks

Back to confirm that is definitely not correct address. I tried to take my other car for a spin to see what it would do since it has a wideband installed. I was much more aggressive with my adjustments since it has a twin disc and a bunch of other lightweight rotational parts and it was undriveable. It's definitely a fuel modifier it's changing, AFR's in the low 9's to mid 8's at idle. If anyone has the correct table that would be awesome

I think @CDrinkH2O is still active, maybe he can help us. I need a file with these tables for the USDM IX so I can relate to the happiness these folks are showing in these old threads
