Holley has an injector driver box.
Might think of using a GM ecm, thru that injector driver box.
The syclones were a 2 bar MAP system, and the computer code is hac'd.
I'm running 55s on a lil 231 (SEFI, thou), and have an injector time at =
idle about 3.1 msec.
Depending on the wiring in the ecms you might not be able to share =
sensors between the two. Might be worth putting an ecm bench together =
to really study what you have.

Hi,
I'm new to the list. My project is a 73 elcamino with a destroked 400 =
small block (377).I'm going to use a D1 ATI supercharger with an =
intercooler and EFI.
At this point a have purchased a pair of used accel 74022A ECM's. My =
plan is to somehow combine these two so a can have eight peak/hold =
drivers. I don't feel good about using 8 50 lb high impedance injectors =
with the simultaneous double fire that this unit is set up for. The on =
time at idle would be far less than 1.5 ms.
Does any one have access to a schematic for them or know where to get =
them?
Accel is no help at all.
My concern is how far back into the board do I need to grab the =
control signal to turn on the new drivers as well as whether the =
controller can turn on 4 drivers instead of two with out problem. =
=20
Looking forward =
to talking to everyone
