Re: Driver board group buy closed.

Hi David,

I would like to confirm the order of one combo board as defined on the
website. To fill in the question marks, I'd like 8 active hi coil drivers,
and 8 injector drivers. I'm not sure whether I need active high or low. Do
you know what the traditional GM TPI is? That is what I intend to start
with. I'm hoping that the development will mature sufficiently to allow me
to hook it up to my LS1 (which I'm putting in a 64 Impala SS). The LS1 has
all the injectors wired to 12volts, the PCM applies a ground on the other
side of the injector to fire it. Is this active low? I'm guessing that it
is. It the TPI is different, then I need to be able to change the
configuration of the board at some point. But......, for now I need to be
able to work with TPI. I hope you know if they are active high or active
low.

On the ignition side, the LS1 uses coil packs (8 of them) that appear to
include the driver. There is power and ground running to each coil, and a
control signal. So........., I will be trying to understand what logic
levels I need to drive them. I will have the engine running soon on an
engine stand so will measure that signal with a scope.

thanks for your help!
