Default MS3 Starts/Runs rough, Rich as $%#$ nothing helps

95 NA
Stock engine / Injectors
MSLabs MS3Basic 1.2.3 Firmware
Innovate MTXL Wideband
GM IAT

Car runs great on stock ECU, Starting the car on the MS3, It starts but runs very rough (like its on 3 cylinders) insanely rich 8:1 - 9:1 Changes to VE table or Required fuel seem to have no effect.

Checked ignition timing last time I tried to get it running right, set MS to 10deg fixed then used a timing light and the crank pulley read 10deg so this isn't a timing issue I don't think

Maybe there is a setting im missing or something, I'm pretty fed up at this point lol

Here is a data log, MSQ and a Composite log of cam signal for you guys to check out

and its tapped to the vacuum source correctly and no leaks? cause that's the 1st symptom of super richness: map reading too high.

is this a fresh install or did it all of a sudden start doing this?

According to your tune you are, and your VE1 and VE3 tables are pretty different.

Not active, but enabled, and the values in VE3 are extremely low. Makes me think that VE3 was being adjusted instead of VE1.

What had no effect?

Did you reduce the values in fuel table VE1 and or reduce ReqFuel?
