Hi everyone id like to start off by saying the program is wonderful and super user friendly if you’ve done some dabbling in tuning before.
I’m Happy and can’t wait to continuously learn the more capabilities it has to offer.

As the title says. I’ve got a Turbo M54B30 with the Ms45.1 ecu in it. The car is strictly a drift missile and slowly being built up for it.

I’ve recently installed bigger injectors and that got me biting the bullet on the tuner.

I have followed mswixi guide to the fullest of my capabilities without adjust any tables without understanding the steps from the correctly.

If someone could help me tune out the car it would be greatly appreciated.

The car starts and runs. But dosnt idle nice at all nor does my A/F Gauge like what’s going on it goes either direction way to much and the gauge reads “ - - - “
If someone could help or point me in the right directions that would be great. I’d honestly love to fully do it alone but I’ll leave it to your professionals ;)
