1 week until ours gets finalized. The beauty is that you will be able to buy it ready to go.
As for the RX-7 version, we hope to become a Ludwig customer.
The OMP function is something we're working on. Currently it's in a stock operation mode. The originally intended market is street cars but I'm pushing for a "track" mode. I'm getting what I want it's just taking time. The developer has already produced a "chip" that has the OMP feedback loop deleted. Leaves the pump operational but eliminates limp mode. This is something that should be incorporated for the "track" mode final product.
The 6PI and VDI functions are not only retained but are tuneable. You can reset those parameters at your desire. The AWS system is also user defineable. The underlying use for this in a street application is as an aux output. Since the AWS system is not that desireable you can use the output to control something else if desired. For "track" mode we're looking at using the AWS at WOT the same as the others are using the BAC valve. Introducing more air into the plenum than the throttle body can move by itself. The BAC function is NOT user programmable.
Of note for the street user is that the system will support AFM removal turning the system into a speed density type system. It also supports optional injector configurations up to 720/720. More injector than you'll need for an NA car but simple turbo swaps become possible.
The interface is strictly Palm OS. You need a Palm or something compatible. Since I had no prior Palm experience I was skeptical but it turns out to be pretty handy. Palms are available for a song on Ebay (mine was actually given to me by a friend). In addition you'll need a synch cable for your particular Palm that connects it to a standard serial port.

Good reminder...I found - at the wheels (in DynoJets)
8hp at the peak
8ft/lbs at the peak
As much as 11.1whp and 11.7 ft/lbs in some spots
Raised the whole curve up almost 4hp and 4ft/lbs
Extended my 'core' hp curve (as defined by me of over 130whp) from the 6000 to 6800 range to 5400 to 7200
Extended my 'core' tq curve (as defined by me of over 120ft/lbs) from the 4700 to 5300 range to 4400 to 6000
We also were strapped for time so we only really focused on nailing the A/F and ignition timing over 4500RPM.
Andy, I have been talking a bit to Kelly about you new ECU. Sounds very impressive. (Just what everyone in the NEDiv needs, you to get faster. 
) The comparison you make above was to a stock ECU? In a 1.8 with ITA built engine? Was the comparison back to back (ie, dyno runs on same day/same conditions except for the ECU)? I know dyno results are sensitive, but I was wondering if you would be willing to post any showing the comparison you describe. Just a thought.
I am going to try to get up to NHIS at some point this season. I have family in NH so it would make a nice week combining a visit with a race or two. I'll look for you if I do. If you get down to Summit for a MARRS race, look for yellow # 5 Ita Miata.
Thanks, Bill

No. It was with a 'flashed' OBD-1 ECU. Basically the same effect as pulling fuel pressure out. Baseline numbers with stock ECU were more peaky and about 5 hp/5 ft/lbs below what you see as the '2nd' baseline above.
Yes. .020 over balanced and blueprinted bottom end. Boig header and proper port match. Kelly did my latest cylinder head, did the porting, the valve job and shaved it to grab the half point compression bump.
No stock ECU runs that day but the programmable to flashed is applicable. I am confident that you would raise the HP and TQ curves up a full 10 each from the stock box.
Bring your Miata and come to Lime Rock and have your family meet you there!!!!

This solution will sell for about $2500. Ain't the cheapest but ain't the most expensive. Puts the effort and solution Chris has into persective. I love my system, and there is more to do but Chris really knocked it out of the park!
of course i wish it was $500, but that doesn't sound like a bad deal at all for a plug and play solution.
I think of it this way, a pro motor might net you roughly 10hp over a nice crate and cost you $6000. this will get you about the same benefit for less than 1/2 the cost. sounds good to me.
