Microtech, anyone got a story?
Hey I'll be getting a Microtech very soon for my GTU, it will be the commander and chief of my 89 J-spec (damn good looker). I have seen it in action on a number of different rotary applications, including a couple of 12.50 second first gens running stock turbo II engines.
I was basicly wondering how hard it is to get tuned in to what you want it to do (basicaly run smooth with minimal gas consumption). Any stories of it being really hard to tune? Or is it a pretty easy job to get done.
I will keep you all informed on how it goes, I am going to do a tutorial on the whole installation.

Relisys190 recently installed a Microtech on his NA RX-7, so you may want to send him PM for information. Thread here:

Running Smooth:
The current LT8 and LT12 are really intended more for a turbocharged engine, and my concerns about this are voiced in the above thread. However, I'm sure that the Microtech computers will still work OK on an NA. It is just going to be difficult for the engine to run smoothly on such a coarse EMS. Hopefully the new S models will have adjustable load bands to take care of the NA issue, and the new 32x32 map will greatly improve smoothness.
Fuel Consumption:
A decent engine tuner can make a standalone EMS produce better fuel consumption than stock, assuming the rest of the engine is somewhat stock. Once you add big turbos, porting, etc., fuel consumption is going to get worse. I wouldn't worry much about the lack of closed loop control on the Microtech, as most people who own an EMS with this function don't even use it on their sportscar. As usual, the trick here is to have somebody smart tune the car rather than trying so save some money by tuning it according to what you read on the internet, which usually results in a blown engine.
Hard to Tune:
Anything is hard to tune if you don't know how to tune. Just keep in mind that there is more to tuning than plugging in some specific air-fuel ratio. The "little things" are really difficult to tune, such as acceleration enrichment, temperature compensation, fuel injector phasing, etc. You really need a professional to tune the EMS, at least for the initial tuning. No, you can't just download an EMS map off the internet and expect the car to run correctly.
