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

Gt2560rMiata

Nope vacuum line is all hooked up to the MS3 properly

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?

Rev sent me a tune with a VE table 20 points lower in the low KPA area up to 2k rpm. This had no effect still running super rich 9:1 plenty of white smoke out the tail pipe

What exactly are you doing with table switching?

Gt2560rMiata

Im not using table switching.

Do you happen to have IdleVE switched to on and trying to change the normal VE table?

Gt2560rMiata

iTrader: (-2)

IdleVe is off

Ben

iTrader: (33)

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

Reverant

iTrader: (10)

They are not active per the data log?

Ben

iTrader: (33)

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

Tryed different tune making sure table switching was off. Had no effect.

Ben

iTrader: (33)

What had no effect?

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

Gt2560rMiata

iTrader: (-2)

Turning of table switching, which wasn't active but enabled. Ive cut reqfuel in half, also tried uping it 50% either way it wants to run poorly at 9:1

Stuck injector?
