going single i think with a 40r what is the better one keep in mind i will not be tuneing it i will have that done.

 

Great idea. Too many people try to tune it themselves and end up ruining their engine. Just ask your tuner which EMS he likes, and buy that one. Better yet, ask your tuner if he can put together a package deal. Regardless, you do not want to bring your tuner an EMS that he has never seen, and then expect him to tune the engine well, and in a timely manner. I don't think that you want your new engine to be the guinea pig for your tuner's experimentation with a new EMS.

 

good reply i will ask him

 

Dont' know about microtech because I've never been in their section, but PFC has very big section and people who use it....so, more forum support.

Yet, I've been told that Microtech is better for rotary cauze people who make it designed it for using with their rotary engine!

 

Both Microtech and AEM were designed on/for a rotary, the thing is more people know windows than Dos or Linux, yet windows is nothing to sneeze at but might not as efficient in waht it does as Linux...

Power FC had been around for a long time so people can give you a lot of help since a bunch have "Been there done that"
The other two are a bit more adventerous, but both seem to have had an insurgance of tuners that are learning how to run them well, and possibly better than the PFC... the question remains, can you find one near you. Best place to ask might be AEM & Microtech... since they certify tuners on their system, they know where you should go...
