ms doesn't run this very well at all. I did a temp-compensated alpha-n setup on a 20 valve using ms. I've never been a huge fan of MS, as you probably know. The project interested me though, as it was different than most other things I usually tune.

MS doesn't have very good flyback protection at ALL. The VVT coil was enough to cause reboots. Trigger issues were all over the place. I think there was some conditioning we did to fix that because there apparently is no internal VR conditioning. I got acceptable drivability and performance out of it. The throttle response was unreal, but ITBs generally produce this quite well. MS doesn't allow you access to the temp compensation corrections, so temp compensation sort of sucked in the winter. There wasn't much I could do outside of trying my luck on someone's half-assed code from the forum to unlock this. I didn't want to go that route.

All in all, it delievered on the cost, but man was it problematic!
