That's a very nice write up and it answers my questions.  It has enough inputs that it can handle
Satellite TV and still go fast. :D

They took a well proven platform and tailored it for the Buicks so they did not re-invent the wheel but they customized it specifically for our cars and added enuf features to make it run out of the box without having to import a trained monkey to tune it after each race.

The best thing is that it was brought to market by two really nice guys that have always bent backwards to help people.

Eric has an excellent support forum for his products and Bobs. The support for this ECU will be second to none...compare d to the alternative.

Jason did you verify timing ignition timing?

Steve - until people stop tuning off knock threshold they are still going to break stuff.

All I know, is that if one is running 25+ psi of boost and the fuel hiccups, one has a very expensive mess left under the hood.

I don't know exactly what you mean by knock threshhold as I have always run a couple of percent more fuel at a minimum than what testing showed I could run without detonation as I have found it makes minimal difference in performance to be a little rich.

I also know that fuel quality varies as do ambient conditions and I like to stay away from all the possible lines that I can think of.  Having a management system that tries to save the engine seems like commonsense to me if something goes wrong.

Having the ability to monitor fuel pressure and alert me early is better than finding out that the pump is going away too late.

I distinguish between warnings and tuning.

Steve - Iím talking about the guys that keep turning it up until it knocks, and dialing it back some. Where they could have snuck up on it and found that itís perfectly happy with less timing than they are trying to feed it.

This ecu can do all of what you want and then some.

Swapping in a new fuel pump once a year is cheap insurance against losing a set of head gaskets...but I'm prolly making to much sense.

With the exception that some pumps may die two weeks after you buy one, you are making good sense!

Door 1. You can change your fuel pump once a year. It's about a 2 beer job and hundred bucks for a new fuel pump. Door 2. Or, you can go WFO with a pump going weak...and learn how to pull your engine and swap head gaskets and spend a crapload of money. Door 3. You can also leave the engine in, and lean over the fenders to change them and blow your back out.
