24x Reluctor Wheel 58x PCM Programming Fix?

I'm looking to install a nicely built LS2 into my 07 Z06. The issue is the LS2 has a 24x reluctor wheel and my PCM is obviously looking for a 58x wheel signal. I was planning on using the LINGENFELTER converter box but it now sounds like they are on hold pending more testing!

Sooooo, I don't really want to pull the crank to get a 58x wheel pressed in so I'm wondering if anyone has had any luck at getting the the PCM programming to make the change there? I'm assuming this may not be possible or Lingenfelter wouldn't have made the module.

I'm still curious to see if anyone has found a way to get into that programming area or has found another way around this issue.

Thanks,

-John

Re: 24x Reluctor Wheel 58x PCM Programming Fix?

That cannot be done via the software in the E38 PCM C6 LS7/LS3 as the hardware logic is designed for the 58 tooth signal and as it is there is no software tables for signal difference in the 2 types

LS2 used the E40 PCM which had different internal hardware

And unless there is another model their website says that converter is the other way around in allowing 58 tooth reluctor signal being used and converting to support the older PCM expecting 24 tooth signal

Says :

The Lingenfelter TRG-002 module allows Gen IV GM V8 engines with the 58x crankshaft trigger or reluctor wheel and the 4x camshaft timing gear

to be installed in earlier vehicles designed to accept the 24x crankshaft trigger wheel and the 1x camshaft trigger wheel without having to take the engine apart to change the cam timing gear or the crankshaft reluctor wheel.

They do make a 24x to 58x but it's on hold as of right now pending further testing as I understand it.
