How I saved $500 on an eRod Right now they have a $500 rebate on the automatic version of the eRod, but not the manual version that I needed. So I ordered the automatic version, changed it to manual, and set the reluctor tooth count to the 12T I need.
The automatic is 40T and the manual is 17T, but my TKO is 12T, so I was going to have to edit it to get it close to right anyway (I suppose 17T might have worked for decel fuel cutoff, don't know).
This wasn't entirely intentional on my part, but it worked out in the end. I wasn't even sure HPTuners could read and write it (which it can - a good product but with no real support).
In the flash there two almost identical settings in the HPTuners UI for output shaft tooth count and one is set to 36 and the other to 40. When I asked them what the difference between these two settings in their own UI were, the answer was "The online help sentence is the only information we provide". OK. So I don't know why there are two, but I'll set them both to 12T for me.
So far as I can tell there are no other difference in the calibration, but I can't prove it yet...
(BTW, I get that buying an eRod is not the most cost effective way to get an LS3, that wasn't my point)

Yes, from what I've learned:
GM automatics: 40 teeth per revolution
GM manuals: 17 teeth per revolution
Tremec TKO: 12 teeth per revolution
On the 4L80E you can see the reluctor if you pop out the sensor. It's a square-tooth "gear" with 40 teeth on it.
Why the one table has "36" I have no idea.

yeah I have had issues that the HP tuners service couldnt help with like that. they dont know anything about the "hardware" aka the actual sensors and car parts, they just know the software side. but they are damn good at that and pretty helpful too.
