[Shotimes] Re: LPM program for D4U1

[John J. Weidenbenner]

I'm not interested in bypassing Ted B., but rather hear peoples experiences
with various changes so I can pick the best mods for my application. That
does a couple things; educates me on what can be done, and should reduce the
development iterations. Ted B. will get the job reprogramming the chip.

I'm curious about the line pressure comments. Are there enough mechanical
variations from one atx to the next to cause the programming to be unique
for a particular atx, i.e. spring forces and piston friction.

The tuner you mentioned, is that hardware/software as in SC Tuner/LPM/etc.,
or some guy programming for you?
