Hi all,

I've got a 76 REPU with a supercharged GSL-SE 6 port, and last year I picked up a mostly stock 94 FD.

So... my name is Matt and I live in Northern Colorado.

My first car was a Silver 1978 1st gen RX7 which was *atomic*. It was air-born at least twice, carried 7 people at least three times, and put up with far more from me than any car ever should have... made a believer out of me.

Since then I've had two more 1st Gen's, parted out an RX2 (4 dr), still own the REPU, a Suzuki RE-5 rotary motorcycle, and recently got the 3rd Gen.

Right now I'm making an FD computer diagnostic fixture and engine simulator so I can program and verify everything on my AEM EMS before ever putting it in the car. It's working nicely so far, and I can post pictures of it if requested. I'm also trying to use it to model the operation of the stock ecu, but any interesting results there are still a long way off.

Gotta love the rotaries,
Matt

He was an 11 second sled, so you know I killed him.

Actually, I've only been to the track twice and my best run so far is a 14.090 @ 102.49 (and 5800ft elev)

Well Will, I checked some of your posts, and I'm in Fort Collins (like you), want to run E-85 in my 7 (like you), and recently am into engine management systems (like you). We should get together sometime. - Go Rams!

Yea anytime, there are actually a few of us rotary guys around town. There's even a Maxton Roller Skate just down the street from me. We occasionally meet up BBQ, make a mountain run, and break rotary parts :/

Post your ECU fixture if you don't mind. I may know a thing or two about circuits if you ever need anything.

White FD is the way to go. Welcome to the site.

Your R&D into engine management is definitely interesting and worth sharing. Post up your progress and pictures in the Engine Management section.

I look forward to it.

Thanks for the Welcomes everyone!

I had to look up what a "Maxton Roller Skate" was... I used to see these all the time when I was a kid, but haven't seen one in years! I had no idea they were made in Colorado or had rotaries - too cool!!

Here's the current state of the fixture...

Dave's calling it "Frankenstein", so the name is starting to stick.

The lower cable/board can be plugged between any ECU and the stock harness. It has selectable monitor LED's for almost every ECU output (including injectors and igniters). It also has a communication board for talking to the stock ECU (thank you Enervation!) and tapping switches for inserting a wideband or different MAP sensor.

When not in the car, you can plug in the top board for simulation. The simulator has input pots for TPS, MAP, O2, IAT, CT, etc. and input switches for gear selection, brakes, starter, etc. It also has a programmable microcontroller for generating the G+ and NE+ crank angle signals with a single pot allowing you to set the RPM.

I set it up with the AEM, but now I'm updating it for the stock ECU so it won't throw codes and runs the CAS correctly. Once these updates are complete I'll post it in the Engine Management Forum.

Wish me luck!

Thanks,
mma
