MAP Info Needed

[pontiacgp]

I have what they used call the 1.0, it's only good to 650 hp so I had to remove some stickers on the GP. I am using the MSD 85551 now but I also have the MSD E curve that I might drop in since that can be used with or without the box. The E Curve sets up the same way with it holding back the timing so if the box ever died, like MSD boxes have a habit of doing, I would just have to change a few wires and settings on the dials in the distributor and I'd be on my way

What model of the FAST EFI do you have? Which distributor?

the Fast 2.0 which is rated to 1200 hp has this..." Electronic Fuel Pressure Measurement • Nitrous Timing Retard • Electronic Timing Control "

if I get the 2.0 I can put the stickers back on the GP and even add more...

Pages 21-22 refer to the MAP reading vs. LOAD%.... how's your load?

To answer your original question, they are 2 separate systems that can't be combined, unless you upgrade.

In regards to the eCurve, I would think the Pro Billet and 6AL_2 would provide a more stable curve than a module. Your dreams of having an onboard backup system seem optimistic. I have seen racecars run a backup ignition, but I've never experienced a box failure. I thought I had one once, sent my box back, and they replaced a resistor, but the real problem was the rear float being set incorrectly.
