Does a throttle bodie setup still need an afm?

You mention resolution Ben. Do you do your mapping on an engine bench against a constant load dyno? If so, then the more expensive high res ecu's make sense..If you'd see how most of the cars end up being mapped, then usually the less they have to play with, the less they can ruin.

Don't agree that the MS is inferior to the rest..even the older versions performed better then carbs (which would still run almost every engine out there). Newer versions get higher resolution, no worse then eg DTA. The VEMS is basically the same thing..open source architecture develloped by amateurs. Just that a couple of people started producing the thing more seriously reducing the geek factor.

Whatever ECU you choose, I think that the performance achieved is about 90% mapping vs 10% ecu capability. If you are just guestimating on a dynojet, then interpolation works just fine.
