[DeTomaso] final verduct on self-tuning fuel injection

Tue Oct 4 15:08:23 EDT 2011

This is with the new Electromotive system.
I was completely happy with the old Haltech system for many years.

I should note that the Pantera has been running a little over a week. Goes
like stink.

The Electromotive system in my GT40 is also working well. OK, as many people
know, I did have issues with a defective harness in the beginning, but once
that was tracked down and replaced, no problem.

Several people have driven and ridden in the GT40 and nobody that I can
think of wasn't impressed.
So I consider it 100%.

The Pantera will probably take me another two weekends. Unfortunately, I
still work for a living...
  :-)

I might even do a dyno, but I've found my 'seat of the pants' methodology in
conjunction with a wideband O2 sensor works pretty well. It's cheaper, but
it just takes longer.

FWIW,
Kirby
