Our car has both the elements of a difficult tuning process: #1 Unfriendly ECU and #2 Hot-running engine. If you have tried tuning this car yourself, you would know that you can only make so many runs (street or dyno) before you need to let it cool off again. Cooling and avoiding knock is very important in terms of safety and reliability in your tuning. If these guys take them 2 weeks more to tune it right, I wouldn't complain as long as they get it right.

Everyone give Scott some patience and breathing room. Tuning is a long process, if you understand what he went through to get the turbo folks up and running, you'd understand why he is so intent on doing the N/A right.
I can attest to the time it takes as we have been working on my megasquirt rx8, and RG's megasquirt 1st gen, getting driving maps tuned in is truly a art. Given Mazsports history, I'm sure Scott will have nice product in the near future.

The real advantages of the interceptor is the packaging (the nice box, harness) and the code to read the stock ignition tirgger wheel. I'm sure there are some other minor features, but those are the only real differences between a microtech unit of the street and the interceptor unit.
And I don't mean to make it sound like those changes are by any means insignificant, believe me, the bitch it is to get the harness working and the proper code written.

Microtech are very good like that.

Actually the Microtech Simon installed on his customers car doe's have the code for reading the trigger wheel & also comes with the harness adaptor. We aussies have some great rotary people :D
I was in his workshop last weekend talking to him about it. The 18kw at the wheels is nice but more importantly there are some very good under the curve gains and some great improvements down low!

does the microtech address the drive by wire issue? i doubt it
i know of two rx8's in the US with LT8's installed...they are both coverted to cable throttle, have a fuel return line added, etc etc etc...
way too much chopping up for my interest...and they always have a MIL

From my megaquirt work, the DBW is not really an issue, I'm not messing with it, and I believe the microtech just lets the stock ECU control the DBW as I do.
How Microtech got the code written for the stock trigger wheel is a interesting story I am piecing together. Here is what I know so far:
Pettit Racing, who also works will Microtech, does some engine building for some of the rotary open wheel race car series (Cam told me the name I just can't remember now). As I understand it, Pettit was working on a building about 100 renesis engines for these little open wheel cars, and got with Microtech to write the code that would allow the microtech to read the ignition wheel.
So, somewhere in this Mazsport I believe must have contacted Microtech for aftermarket rx8 applications, and started working to take the microtech to the next level for a street car.
So from what I can tell, the genesis of the microtech being about to control our cars came from Pettits work, as it gave Microtech a reason to devote the resources to write the code, afterall, microtech was going to sell 100+ units for this series.
These "Pettit cars" don't use the DBW, as I don't believe the microtech can control it and its cheaper and easier to just build a cable throttle for the engines.
Again, this is what I have pieced together from a couple of sources, but seems to make sense.
Now, you may be asking, why isn't Pettit using the Microtech for there supercharger system? Mainly because they want a simple pretuned, plug and play system as they are focusing on cost and the user who wants it to "just work" and doesn't care about tuning it himself. Personally, I think that you shouldn't be supercharging your car if you don't know how to tune and maintain it, but hey thats me.
As I understand it, you could buy the Pettit S/C hardware without management and simply buy a mazsport unit. I've I had the money, thats what I would do. You can contact Pettit about purchasing the hardware.

The trigger wheel code would have been no big deal for Microtech. They do custom ecu's all of the time.
I dont think there is an engine around that Dom at microtech couldnt configure an ecu to run.
90% of rotaries in Australia are running Microtech's. Its only natural that they would do something for the RX-8

From my discussions with Simon the microtech being used here in Aus on his cars is very similiar to the interceptor X in how it is used. No need to install cable throttle or anything like that. Lets the stock ecu handle most things while it looks after fuel, timing/ignition etc and a few other things but I cannot remember all he said. A bit too technical for me. It's my first rotary :D

It's very easy to keep the stock drive by wire. You leave the stock ecu hooked up to the car. You just disconnect the stock ignition system and fuel injectors from the stock ecu and let them be controlled by the new ecu. It is literally just cutting a few wires and adding in an ecu. No piggyback, no fooling, nothing. All works just fine. There is nothing hard about it at all. I am at a point now that I can tell anyone which wires to tap into if they want to try this. I will at some point do a diy writeup on this after I have the Megasquirt project completely done. It doesn't matter if it is Megasquirt, Microtec, etc. It's all the same wires.
