That's my problem too. The M5 is my daily driver and I can't afford to be down a couple of days with no car. I was hoping there was a Southern California site so I can just have it flashed locally. Other than, I would do this mod in a heartbeat!

Just shipped out my ECU to ESS. Wish me luck for a new and updated BEAST. Roman is great to work with!

PS Roman, I forgot to ask, please include the Sport Mode memory in the programming! That's a great feature! :)

When you disable the SAI fault codes with your latest software, does it in turn disable the SAI pump alltogether? Looking for software with catalytic converter efficiency/conversion codes disabled (catless exhaust). At the same time, disabling ALL SAI pump error faults. SAI rail @ bank1/bank2 will be subsequently deleted with blockoff plates at cyl. heads, as well as removal of SAI pump.

Got anything up my alley Roman?

I've got exhaust and stainless tubing/bends shipping my way now. I will have my setup complete in 2 weeks. I'll be in contact, thanks for the response!
