I've got all the hardware bugs resolved and have finished up the majority of the ROM code. Once I get the application updated it'll be all set for use in some cars.

The retard amount is good to know. Have you by chance found any information on what the sensor's output is? I realize it's piezo etc, reason I am asking is that I was considering running 'stereo' KS's, one on each rotor housing.

Ok everyone, I've been told we need one more guinea pig for the prelim trial. Who's in? I've got parts waiting to build this thing, so someone else needs to message SonicRat and get on board with this!

I've got the next batch of boards on order which will be going out to some testers in various locations. I swear, I really need to stop adding in new features, it's holding up everything, lol.
This project has kind of ballooned quite a bit from what I had first expected to do. I was first just planning on doing the basic things, similar to what RTEK does -- fuel, ignition, transition, and leave it at that. But, as I've gone on and stumbled across the routines in the ECU i've added in new functions for those as well, such as: idle speed control, air/water temp timing correction, cranking fuel maps, secondary injection fuel differential, afm removal, etc. It's taken me a lot longer to get where I wanted to be, but the result is a lot more control over everything.

I currently have 4 S4 TII ECU's on hand, so I'm good there. It'll just be a matter of bug fixing/adding features into the code for the S4 TII group now. The board should fit the S4 NA as well, but I've not yet worked on their ROM -- although once the TII one is finished up, the S4 NA will be extremely easy as many routines are very similar.

WARNING DUMB QUESTION AHEAD: Forgive me if I have missed any posts on this: is it possible that the datalogging etc could be accessed via iPhone or a tablet, or ???

I forget if I asked it via PM or on here, but I believe NO was the answer. SonicRat had no intention of creating an interface for phones. You could always emulate the palm on an Rtek if that's what you're looking for.

I don't feel like paying the $99 to be able to publish Apple programs, and I don't believe their bluetooth stack supports serial anyway -- so it'd have to be a custom fab job done with either the microphone or a some other cable job. Android would be fairly straightforward to do, but I doubt I would have the time for it.

For S4 or S5? I don't believe at this point I would really have any use for a S4 chipped ROM, as I've already far surpassed what most of those chips do with the S4. The S5, I have currently done no work at all on, although I do have the stock N374 EPROM from one.
The "list" of S4 features so far:
There's a lot more left to do as well...
The "list" of S4 features so far:
- Adjustable Ignition Tables (20x20)
- MAP Based Ignition Tables
- Adjustable Fuel Correction Table (20x20)
- Adjustable Injection Staging RPM
- Adjustable Injection Staging Percentage
- Cranking Fuel Map
- Water Timing Correction
- Air Timing Correction
- Boost Cut Limit
- De-Flood Proceedure
- AWS Disabled
- AFM Removal
There's a lot more left to do as well...

I have an N333 on the way, once I test it and make sure it works in stock form I'll be sending it on. I can shoot you the two unmolested N374's I have as well. Will PM you when it's all ready to go.
Dumb question (yeah I'm full of 'em): is it possible to run 4 individual ignition coils with this setup? The stock trailing ignition uses a 5v rise/drop to determine which coil to fire, is it possible to add a daughterboard etc to do this and thus eliminate the stock amplifier module? Or is this getting way out in left field?

I may have the same PROMS at home, I can probably desolder them and make a dump for you.
Also, if you throw me some protocol documentation, I will give a shot at making an android app
