I measured my set of Bosch injectors sourced from a Ford Thunderbird
Supercoupe (the supercharged 6-cyl motor). The flow rating is 295cc which
should be perfect for making a little bit over 200hp at a slightly raised
fuel pressure. Duty cycle should be about 85%. The average resistance came
to 14.9 ohms.

Yeah, the G60 ECU can work with this level of resistance just fine. However,
it still needs to be reprogrammed since the injector flows more. This will
cost me about $75 per batch of chips. I'm anticipating the need for two
rounds.

Ah, yes. The TEC-II will be installed in my high-strung 323GTX. With high
compresion ratio (9.5:1) and up to 14lbs of boost, I need all the control I
can get. I might just trade the unit in for a TEC-III, though. There are lot
more nifty features in that system. The biggest shortcoming in the version
that I've got is that there is only one auxillary output. That will be used
for boost control, of course. But, then there's other stuff that I'd like to
play with like water injection, etc.

Well, you've got a customer right here if/when you get that thing together.
Wideband O2 is the only way to fly. Come think of it, wasn't I just
corresponding with one of you gurus about manufacture of neato electronic
gizmos? There is definitely a Scirocco-l lister that can help you with this,
Dan. I just have to figure out who it was... Allyn, could you pitch in with
this? But, damn... who else was I rapping with?..
