Hello everyone I tuned a 2015 si last night and after dyno tuning on the road calibration I was getting a check engine light for p0102 low maf input and then all the vsa lights were coming on.

I haven't had this issue before and the customer left his car at my shop so I can fix it

I tuned the car with the speed density map if that helps any, car runs great I just don't know why it's now throwing maf codes and vsa codes

I haven't had any issues with any other cars doing this but this is the first speed density map I've tuned on

Any help would be appreciated thankyou

There's a disable for P0101/2 in the software.

is shutting off the vsa monitor helpful at all. I shut mine off thinking it was shutting off traction control with 2 step at 2900rpm and 2895rpm restart and when i let off clutch the traction control kicked back on and cut power to my wheels. is the vsa for the traction control? Thanks again for any help given. Trying to learn tuning so any help is appreciated

That's the error for the module.

Error for the module? If I turned off vsa in the software to disabled vsa. Why would it still flash on when losing traction on a launch and cut power to retain traction if it is disabled all together. I still have to shut traction control off via the button on the dashboard?

See how it says an error number next to it. You disabled that error, not the module.

ok so how do you in the software disbale traction controll?

You don't. VSA is a separate module.
