Update - posted my latest maps, so linking from the Rennlist thread... tuned for US 93 octane gas (though far from the limit, I have a WBO2 sensor but no knock sensor and haven't run on a dyno, just s ...

US-spec 931, but here's my ignition map (from the Megasquirts experts thread):

LOL

Yeah, Don and EBS are great to work with, I've been using them for a long time for various bits...

Yeah, they do that; I was shocked when mine did the same!

My EFI 931 is now so reliable my wife loves to drive it without me!!! Fun to drive, easy to start, drives reminiscent of (though obviously ...

Yup, that's a quick easy answer there. Start at the coil, verify you have power there (should be 6V with ignition on, 12 while cranking), then go through the wiring for the pickup lead from the distri ...

Super-secret work job!

Ford I mean Chrysler nee FCA maybe Stellantis who the hell knows next Proving Grounds are out there (Stellantis laid off 400 engineers while we were there, was a bit of a ba ...

Man, I was just in Lake Havasu for a couple of weeks... fighting with transaxle issues... if only I'd have known these guys were in town...

Well, it's easier to pull a spark plug wire and see if you have spark there, than to pull a fuel injector and look at that. So definitely check spark first.

Seems like you should be able to order the bearing directly by that part number, not to have to worry about using a car parts supplier...

Duh, sorry - the firewall grounding is the same as used for mounting the ignition coil.

LOL! Well there's your problem right there!

There should be a ground strap from one of the intake studs to the body at the firewall, and obviously from the battery to the body. Presumably the one y ...

We run the racecar down at 5" at the sills up front(not including the pinch weld), 5.25" at the rear, by class rules... though I guess we could go even lower now that we've changed classes. ...

Doesn't sound like enough rear camber; from the book, seems like you want to be more like 1.5 degrees. Similarly, too much front camber, book says 0.25-0.5 degrees. Add that to nose up, instead of nos ...

Amusingly enough - if we kept using the distributor, not going crank-fire with an EFI system, it would be ITB legal too. But that would negate much of the advantage IMO, and more to the point ITB is a ...

Honestly I think one of the most time-consuming things when I converted my Turbo was making the wiring. Lots of time invested there, particularly to do it both right and well, IMO actually more comple ...
