Default JB4 Map 1 Log for 2019 G20 330ix - 09-20-2020, 10:27 AM

Did two pulls one in 3rd gear and one in 4th gear. Trying to see if everything fine.

I see throttle dropping while pedal is 100 in some instances and find it odd. I have an MST Intake but I never logged the car before installing the CAI so I'm not sure if the intake is causing this. Someone on the forum suggested the ECU may have been flashed prior to my purchase of the car.

Throttle drops happen in my car too, even when it was stock (Map 0). Do you notice it while driving?

I don't really notice it at all no, it is a smooth pull to me. l almost want to ignore it since it only happens when trying to WOT which is rare in real-world applications. I've logged it cruising and the throttle is consistent.

Do a pull in map 0 from 3rd and 4th gear man

Your DME is commanding boost of 20psi

That’s not a stock tune you’re running

Your timing drops to 0 are a concern

Check out Vipin’s logs

None of them show a DMEBT of over 16 psi

His logs have concerning timing drops too but not nearly to the same level as yours.

Can anyone comment on these logs? Each log has a pull from 3rd and a pull from 4th.

Running 93 octane and MST Intake.

You definitely have an aftermarket tune thats too hot

Same rationale as before

Your stock boost targets are well in excess of what a standard 330 would have and your timing retardation is really extreme
