Ok, here's what's in the next intermediate/preliminary version. There is still some clean-up work to do, but the bulk of the work is done.

Spark control +5/-10 degrees. Full time (like an ITC), once you are above 1000 RPM.
Setting points 2000,2500,3000,.......8000
This will work on Supra's also, with a different wiring change.

Part Throttle AF tracking using the wideband. I'm still tweaking it, but it works pretty darn well. I unplug my O2 sensors, and let this do the work. I set idle at 14.0, cruise at 14.7, and lean cruise at 16.0......

Selectable VE tables, the standard default (my GN) is still in there, but you can select #2, which is my 3S table.... You can still upload to it, if you want, that part is the same.

Config page is now all text labels for configuration, no more cryptic code numbers......

The "hold the button for 10 sec to get to the settings and config pages" stuff is gone.

Now, I don't have the XDF, or ADS files ready, but the 4.60 files still work ok for now...

I need to mail out the wiring to those guys that PM'd me the addresses. I will get the files posted real quick here.

Here is what you guys need to do. (in this order)

Update to the new version, and get it running well in the standard configuration. Be sure all your connections are good, or just solder everything.

Get the software configured for direct spark control (Set vehicle select to 2)
set the Spark advance tables for 0 at every point (both WOT and AUX)

Then add the wire to the harness. I am sending the wire and an extra 8-pin plug. If you already have a boost control harness, just add the wire. If not, insert the wire into the 8-pin plug, pin3.

The White wire is currently tapping the CAS crankshaft signal. This signal needs to be spliced. The wire is cut and the sensor signal feeds the white wire, the ECU side gets connected to the new (gray) wire. There were a couple guys using the TACH signal. This will not work, you must use the CAS signal.

OK.......................?
