Any tried this before? I know the whole speedo thing is the biggie but it would just throw a code correct? The speedo would still operate with the VSS direct. I ask this because I wana use the SE ign tuner for 04-06. I know the plugs are different but that's not too hard to overcome.
I've looked at using the 04-06 DTT TC88A module on my '00 because it has some data logging functions.
Apart from the speedo and TSM/TSSM data bus issues, there is no reason it shouldn't work.

I spoke to Chris Schroeder about this a few years back, and he assured me that it can be done. He referred me to Dan Theyer, who I also spoke to. He can make up a harness adaptor if required. I wanted to use the TC88A on the dyno to datalog, build the ignition maps, and then flash them into the earlier TC88.
I didn't do this in the end, and never thought to ask if any codes would be thrown. We didn't get any 04-06 Twin Cams with carbs over here.
All of the official imports were EFI by that time.
I don't believe I would need an adaptor as I believe the plugs are the same, just need repinned. Also this would allow the removal of the cam position sensor.
Older had 2 12 pin connections and the newer has 1 12 pin connections. Repin what you need and it works.
Joe, straight forward and there shouldn't be any codes to throw. I'll get to the 99 Wiring later today.

Looking closer the only thing that won't work is the CEL.
Speedo and TSM will work fine.
Anyone have any 04-06 ign modules laying around doing nothing?
Does this look right? The CEL and tach would be a no go.

Checked it a few times, and all looks correct.
I'm sure there would be a way to derive a useable Tach' signal from the coil drive.
