Drivability wise, it takes lots of work to get a standalone to match the stock setup. For a race car, you may not worry about the drivability as you are (or better be) under WOT most of the time.
As long as you get good drivability, good AFR and ignition under all conditions with top-notch reliability, it really makes no difference which system you use.
People that do not know the Motronic sell it short. Lots of people claim to know the Motronic. If the end user wants full access, today there is only one option, and it's a standalone system. But who knows, things might change!
Brian, theedge - Nice system. I was thinking of installing a MS on my supercharged 914, the price was very reasonable. I ended up installing a 944 Motronic system with a wasted spark setup. Talk about a project! Old technology, meats new (actually not so new) technology, all Porsche.

Hey Brian! As John knows, I'm tinkering with mine so I can't wait to hear your thoughts on the turbo. It's likely to be my next purchase anyhow...
As far as MS... glad to hear you got it down! Dad and I are having trouble getting MS running on is 911. I think we need a seperate map or control for a 7th injector. You might recall it's a 3.8 big bore with a supercharger. It's using a pickup from an Electromotive twin plug unit. 3.0 had a crank trigger, this motor is based on it, so the timing should be correct. We think it's fuel. Can you could look at a fuel map and see what's up?

The purpose is two fold – it allows you to start barking just a tad later but the main benefit is to use the brakes to rotate the car. No, not like fast and furious, it’s a controlled action that helps the car to turn into the apex.
From a technical stand point not only is this used to rotate the car but it also fills out the friction circle. That’s a whole other thread….

What kinda troubles? Lack of fuel/running lean?

I would have stayed with Motronic, but I wanted a bigger challenge so I went with the MS. Its kept me out of trouble and boredom for many hours so far
