This is a odd one.
This 16 camaro has a procharger and we broke the baro out of the stock MAF. Standard procedure for FI gen 5 stuff. Well this one is still updating the baro. You can see in the last group in this screen shot that the baro voltage remains steady at 3.86 (it should, it is open in the atmosphere) but the baro reading climbs to 108 in boost before snapping down to 100 after the pull.
On some Gen 4 cars setting SuperCharger fitted to yes will fix this but I haven't been able to find anything to work in Gen 5 stuff. Anyone got any tips? P ratio and SD tuning is not going to work out right unless I can get the baro to stick to ATM pressure.
