So who here runs full standalone fuel/spark management?

[superboost]

AEM on the Mustang. Full standalone that give 2 step, TC, N2O control, boost control, etc.
Haltechs on the FDs, except for one really built FD - that uses Motec and is controlled through an on-board touchscreen.

PC3Rs (A/F & T) on the bikes.

I was thinking of doing the onboard touchscreen thing. How well does that work?
