A. Shouldn't matter. Just stay on the clear connector. The pin numbers are molded into the plastic and iirc, cast into the aluminum case too.
I was planning to do it without disconnecting the connector as discussed earlier. The numbers would be on the hidden faces because the connector is still together..

As with Phantom, I can't be 100% how Perf/SGS will affect low-1. The intent is to shift into "D" and the SGS enable signal will force the 2nd gear clutch to engage at 0 mph. If you want to experiment with shifting, feel free. You won't be able to break anything at the torque and speeds we're discussing.
I have since found this out. The instructions to another tuner (dhp) show tables for the following:
(D - normal) 1->2, 2->1, 2->3, 3->2, 3->4, 4->3
(3 & 2 - normal) 1->2, 2->1, 2->3, 3->2
(D - performance) 1->2, 2->1, 2->3, 3->2, 3->4, 4->3
(3 & 2 - performance) 1->2, 2->1, 2->3, 3->2
3 & 2 is for the 3 and 2 shift lever positions. There is no table for the 1 position.
There were other tables for normal detent activation, performance detent activation, cruise control, and hot transmission temperature.
HPT probably just affects the Drive table, or affects the Drive and 3 & 2 tables equally.

Binary files are the ASE spec. and def work with HPT and TinyTuner as well as TunerCats and iirc EFILive. I'd be amazed if most other products wouldn't recognize .bin. As for "different" formats, They're developed by encrypting a standard .bin in a proprietary manner. There may well be different tables as Phantom states. There are a number of tables revealed in TT that I haven't found explanations for. That being the case, I'm in no way prepared to say Phantom is wrong. I can say that adding a dashboard switch grounding pin 21 WILL work(with the appropriate logic field set to 1). And you'll have the benefit of knowing that clutch 2 is locked when you throw it.
I keep learning more about this. But I am not going to be able to do anything in time for the upcoming snow. I read that you can send a .bin file to the PCM with HPT, but that you can't make a .bin file from the PCM with HPT. Is this true?
I read that TinyTuner operates on the .bin file, but that it can't either read the PCM or upload to it. So how is it used?

What BackInBlack is referring to is a whole interceptor circuit between the PCM and transmission and I completely believe Phantom when he says that won't work.
Oh! That! I already deduced that. It would throw the PCM into tranny limp mode.

If you're asking for my assessment of the three methods, I'd have to say that adding a pin, wire, switch, and changing one firmware logic state along with zeroing a single row of values is the simplest and least intrusive way to accomplish Second Gear Start on an 02 Bonnie. Would Phantom's method work? It might.
Since I already built the switch panel, I am going to stick with that.
[QUOTE}Check Craigslist for Performance shops and tuners in your area. BTW, do you know what product your mechanic was using?[/QUOTE]
He had the dhp. He now has a small GM device that can do nothing but download updates from GM and install them, and a similar one for Ford.
I hear that the dhp is discontinued. Is that right?
