""Please don't treat me like a fool""

Ross, I would never do that, and anyone that would is the fool.

remember you're the one that described to me the importance of relays, and changed my thinking about that aspect of electrics. My GT40 has 10 of them now when only 4 were originally planned.

"" but your'e a bit scary when you make
"please don't tell me" statements after questions in other threads.""

Sorry, not my intent, just wanted to let people know I'm already aware of the hydraulic e-brake problems.

""The problem is if you compare maps from similar engines and
you expect them to be the same, you may have ignored things like:
injector sizing,overall trim capability, fuel/gas pressure,exhaust system etc etc.""

I "think" I understand that there are going to be differences, I was just wondering how the different settings are arrived at.

I'm looking for a detailed description of the methods of arriving at any given optimum setting.

For instance with the problem I'm having, how do I determine if it's a rich or lean condition? Does a wide band O2 react fast enough to tell if it's rich or lean? Is it better to do a data "snapshot" and look at it afterwards? Or can you see something like that in real time?

Is the base map going to correct a transitory throttle increase stumble? Or is that better addressed by an "accelerator pump" type setting?

One thing for sure, there are way too many variables with programmable EFI to allow a hit or miss approach.
