That crank, after polishing and rebalancing, is supporting over 400HP in several applications right now.
The MEFI 5A supports variable camshaft timing, multiple event sequential fuel injection, multiple event sequential ignition timing, fully interactive acceleration/deceleration enrichment/enleanment routines and many, MANY more highly sophisticated technologies. The problem with MEFI 5A has not been with the controller, it's been with the calibration software. We have that resolved.
I have produced hundreds of engines using the Electromotive HPX. I know they guys at Electromotive well - they are great people and they produce an outstanding product. When I began the ECOtec project I fully expected to be doing it with the Electromotive system and the ONLY reason I'm not using it is that the MEFI 5A, as pertains to the ECOtec at least, is a FAR better controller. The fact that it also happens to costs a lot less was just icing on the cake. If there was a better controller on the market for this application, I would be using it.
We certainly will need to change and/or modify a lot of stuff to catch up with the 'big boys', but the crank and the controller are actually a couple of the items that are good to go.
