Is MSD's boost timing master compatible with a VAFC hack setup? Does the MSD system override the stock ECU timing settings? I'm just trying to make sure everything i'm doing will work in harmony. THanks

Well I don't know the wiring part of it, but I can tell you this I just got my car back it's a level ten auto with a ls/vtec supercharged setup I have the VAFC running the VTEC and fuel settings and my mechanic just hooked up the MSD 6 BTM and the MSD HVC COIL, and YES everything is working fine with it. And yes they are compatible in my setup, but should be in yours also. Good luck.

Awesome. do you need an external coil or any other ignition components to make the BTM work?

I ran 12.7s with my turbo ITR with that setup, I ran approximately 1/4 to 1/2 degree retard with the hack setup at 10 Psig. It is definitely a touchy setup and I never really got it running right. The VAFC setup advances timing so much that the BTM never has a chance to really pull timing before it's too late...I also use an external coil and MSD cap
