Ditto. This was a real head scratcher, and some closure would be most welcome!

From my experience you should listen to Edelbrock about the wiring, especially about grounds where you can get ground loop gremlins working. You know now that MarkH is their guru for the E-Street...

Bob,
I think what you're saying is that you're going to work with Edelbrock (now that you have the right point of contact and he's back in the saddle this week); and that your ignition is now a new...

Bob,
JL350's advice is good on every point, very thorough and informative with a logical, systematic approach. One thing that he mentions in point 3, On my SBF balancer there are three or four...

Bob,
I just re-read your thread. You mentioned up in post #14 that your AFR is reading 20.94 and 17.92 at different throttle positions. Ideal is 14.7 air to fuel, so your numbers are getting into...

Hey Bob, I checked with Jeff at Edelbrock and he tells me that the FPR on the E-Street is mechanical, no vacuum connection so that idea is a bust! Sorry, thought it might be easy, but no joy....

Bob, I did look at the E-Street installation info and their HP fuel supply system kit includes a stand alone bypass regulator, HP in, HP to EFI, return to tank diaphragm operated for load reference. ...

Bob,
If the plugs are fowling in six to ten miles, what is your coolant temperature at that point? I'm asking because on initial startup your fuel map is biased by a cold start curve which mimics...

Bob,
After I posted on your thread on the Edelbrock E-Street forum I saw that Mark H, one of the moderators and an Edelbrock EFI Techie, advised on 10/2 that he had your contact information and...

Now that's a great idea if it's something that works for Bob. It may be fouling the plugs before it can "learn" the baseline. Bob, call Jeff Robbins at Edelbrock, and see what he says about this...

Jerry, not to argue with you, but the fuel map looks at rpm, MAP, and then assigns fuel flow which on the E Street is then going to be trimmed in a feedback loop using the wide band O2 readings. If...

I think the thin air approach may well be part of the answer, but MAP is Manifold Absolute Pressure, which accounts for altitude vs Gauge Pressure. That's one of the benefits of EFI over a carb -...

Welcome to CHR!!

I looked through the instructions for the Edelbrock E Street system and it requires 50-60psi on the fuel feed, so that means you had to have installed their fuel supply system if...
