Hey, since there aren't any competent tuners in my country, is there anyone that can tune over the net? Recommendations?

 

E-tuning requires a significant amount of data to do it properly and an inside and out knowledge of both the engine and ecu being tuned. The problem I think you will face is the fact that very few people know both the MS3 Pro and rotary engines.

Also, I have never really trusted e-tuning even though many people have had great success with it. The reason I think this is true is because many people who use e-tuning are using newer cars that have much more sophisticated controls in place for things that like to break our engines like knock. So when they log a run, the ecu will handle any problems and the tuner can look at this data to eliminate it...when we have these problems our engine self destruct.

Personally I would suggest taking the time to learn to tune yourself. Take baby steps, read tuning books/notes, read the forums (esp. the Power FC section). It is invaluable knowledge that you will be very glad you have the next time you change up your setup and realize you don't have to find/pay/trust someone to tune your car.

 

This book is a great place to start, one of the authors is one of the people involved with the Megasquirt.

 

I tune one car via emails one time and it was a lot of time involve at the end the owner of the car was very happy with the results on the car but it was a lot of time and headache for me.

 

Thanks everybody for your time and suggestions!

 

I can't even imagine how time consuming tuning over emails would take. As one must work very carefully tuning a rotary, small changes need to be made and if the tuner isn't in the car, they must be very conservative. It could take hundreds of emails to get a car tuned. And that's assuming the datalogs are of reasonable quality.

Live tuning via Remote Desktop on a dyno session would be easier, though not ideal. As long as the car is perfect mechanically and all the sensors are reading correctly, and the Internet connection is fast and stable. Still not something I'd consider.

 

Just tuning for power via email isn't terrible. Tuning for drivability is.

 

I'd have to agree with all the above. The RX7 is a less than ideal platform for e-mail tuning. I can see why the question was asked, due to the fact that in recent years it has become the trend in many communities. Now, the difference between those cars and the rx7 is generally, they are more modern OBD2 flash tunable cars. That also have more advanced telemetry/datalogging capabilities from the OEM. The other truth is, these cars have higher knock thresholds. The final generality here being that most of these e-mail tuned cars are running cookie cutter setups in widely proliferated cars. So in short rare car+unique engine+unique tuning requirements=email tuning unfriendly, not impossible mind you, just a PITA. I'm jealous of your MS3 pro and of course, best of luck on your endeavors.
