Good luck and I am sure you will have a lot of people anxious to hear about your discoveries and results.
Are you aware of the manner in which it is said that Mazsport modified the Microtech? That info may help you along.

 

I didn't really look into it. My understanding is the Microtech has complete control of fuel and timing and the stock PCM controls the rest. Is that correct?

It should be pretty much it. I don't remember if you can tune the ignition split as well with the microtech. That's a key feature for a rotary pcm.

 

We first have to distinguish whether you plan on using an unmolested Microtech or plan on using an Interceptor-X. Scott made some internal changes, from what my partner MazdaManiac has told me, and rewired the Microtech so as to turn it into the "Interceptor-X". Once we establish which unit you will be using we can move the conversation forward a bit.

 

Yes, you can tune the split, however, only by RPM and not load which was a little unfortunate as I like giving it less split at vacuum/low boost levels.

It is the Interceptor-X as it has the Mazsport badging and such. I just refer to it as the Microtech because you use the same software and its pretty much the same as far as I can tell. To be honest, I thought the only thing involved in the Interceptor-X was the patch harness that wired into the stock PCM.

It is my understanding, and I am sure MM will correct me if I am wrong, that Mazsport internally changed the injector staging or something. I do remember MM being a bit frustrated in his tuning of Phil's (Phil's 8) and Tommy's (T-Diddy) cars, although his outcome with Tommy's car was much better than Phil's car. Tommy is turbo'd and Phil is supercharged.

 

That might be the Aux output (sequential+Aux) for secondary injectors that the unit came with as default. Which basically is a fuel table that ONLY controls the secondary injectors. Supposedly to make the car transition smoother.

However, I disabled this and set it back to sequential so the staging now works as Microtech designed it as I didn't think having 2 separate fuel tables controlling primaries and secondaries was the correct way to go about it.

I'm not sure if this is what MM was referring to though.

You may be correct about that and I am sure that once he has a chance, MM will jump in and clear up any errors I may have made. I have to log-off in a minute and hit the road for a couple hours so I will catch ya in a bit.......

Both you guys are tuners. I am just the idiot in BHR who tries to turn the team's ideas into reality.

 

and what does that have to to with the omp?

was that not the point and what you laid down the law about?

how did this turn into tuning camp?

maybe start a thread on how to tune with a microtech lt-10.

My car ran well using the AP to control the idle, OMP volumes, and the CELs created by the Int-X. The Int-X controls the fuel & timing. The reason for my ECU setup is that I have a top mount T4 turbo kit which doesn't allow for proper MAF mounting. It was designed to work with a MAP based system.

The temp problems can somewhat be overcome by wiring a GM Air Temp sensor into the Int-X and registering the charge temps with it. The only way to overcome the OMP is to reflash or to remove it and premix. The injector staging is different with the Int-X but it sounds like you have that worked out.

It seems like you know what your goal is so keep up the good work. There is more than one way to skin a cat.

 

Indeed. I prefer the compressed air method like McDonald's uses on their chickens.

 

What makes the S1/S2 OMP different from the S5-S8 RX-7 OMP's? AFAIK, the MoTeC's could run the RX-7 Electronic OMP's.

 

If you read back, i believe it stated that you can change omp using voltage on RX7 but RX8 OMP is controlled by a stepper motor and is untunable using this method.

Just info gathered from this thread

 

The wird is that he went back to RX7Club with his tail between his legs ... you will probably be the same with that pre-RX8/Renesis mentality

The MoTeC can run the S1 Renesis MOP too, it still has nothing much in common with the earlier version
