Just updating this, I'm in the final stages of trying to fire up the car. Fidling around with the Megasquirt, it cranks but doesn't start. Will be rewiring it once I get all my 4 conductor dual shielded cable for the CAS signal as it might be all from that. Once she's up and running and had some time to tune it a bit on the street, she will be up on the dyno and getting some hard copy results.

Just wanted to update this, that I got the car fired up on saturday, and will have a Dyno/ Tunning Session on May 5th.
Also I just got a new throttle braket laser cut out of 11 guage SS to go the properway. The Supplied Throttle bracket, the cable would need to go down digging into the engine, and the cable would have to be routed to behind the intake Manifold, having to make you make a new Accelerator Cable that is longer and the way that it attaches onto it is a very weird design. My Design, allows you to keep both stock cable, and same way of attachment. To hold the cable in, all you'll be needing is a spare Alternator bracket.
I have already contacted Jimmy owner of Fuji Racing concerning this and have sent him my CAD files so that hopefully the next people that want to order this kit for a rotary engine would have a proper braket.

oo im excited to see ur dyno, although a dyno sheet for ITBs dont really do it justice. the rx8 stock intake was actually designed very well but ITBs are something i just reallyreally wanna do, alot more than a turbo...for now

I actually didn't dyno till today, had to switch spots with a guy, but all in all she went pretty good, she pulls pretty nice and hard, and sounds lovely. The dyno number are way lower than they should be, dyno really isn't tuned properly. I'll post up the graph but not the HP number ... i'll rebook some dyno time here locally, at the good dyno place and I'll post my results from there. But you can look at the curves of the graphs

Like this its a better comparison to my old holley. You can tell that after 5252 rpm ... much more torque than before resulting in more ponies

its this on a 12a or 13b? my ITBS had a pretty differnt looking dyno graph.
the torque would be the really flat line and should be around 150 ftlbs if its a 13b.
In the future I would like to make my own much straighter manifold and put the injectors in the stock ports located on the engine.
My thought is you could get more airflow this way as the ports wont have to flow air and fuel.

the units on that graph are weird! like at 22.4 seconds, isnt 17afr lean?
really though looks like the fuel curve is ok, but it could be leaned out some

Black is AFR,
Red is HP
Dark Blue is TQ
Light Blue is Speed
So i think you're looking at the wrong things, but yes it does need to be leaned out a bit more in the lower RPM range, dipping into 11 isn't where it should be, but I had a couple of things, Fuel Pressure problems, that I think I tracked down to just a loose AN fitting on the fuel filter, and the other one is at that low range its like a crossover section. I'll post the new results once i get on the more accurate dyno here locally.
