Yeah, that looks exactly like what I wanted to do when i was mocking up my supercharger but i stuck it in place of the A/C instead. I'm using the M-90 T-bird SC because i got it cheap! Your color scheme and details look first class!! Are you running a blow through system?

Actually, it was probably the lower rpm bins that looked rich but if it works well then I wouldn't change a thing. I guess Iv'e been pushing my AFRs a little to the leaner side and fattening the AEs but when it comes down to it, I am never satisfied that I have optimum AFRs so I think I am going to invest in some dyno time. By the way, thanks for posting that.

Wow! your AFRs look really rich to me. Your not having issues with black smoke and fouled plugs?

Yes, I had the same problem getting mine to work until I realized The ford EDIS fires the coils in this order: A,C,B.

Wow, that is interesting. I have been having the same problems and at first I thought it was a way too rich after start enrichment but when I datalogged it, it showed going way lean to 16, 17:1. It goes away after the ASE indicator is off. I think it might be a case of going so rich that the wideband thinks it is lean...

What do you have your o2 authority at? The reason I ask, is that if you have it set to say 10 and your ve table is slightly off from your o2 target, then you will feel a slight surge. If it is set to say 50, then the surge will feel substancially worse which should tell you where to fatten or lean your ve table. What I do is drive with the ve tuning table on and hit the F key when I feel the surge and fatten or lean that point till it evens out. I am a total noob to megasquirt but I think this method works well.

Yes, I got hung up on the filter capacitor on the positive coil wire. It's basically a condensor. Thanks anyway!

Try a local electronics supply store where you can buy wire by the foot including shielded two and three conductor wire

Pete, my issues arose when I had detonation under full boost, the Megalog viewer showed my ego running way too lean like 18:1 afr and pulse width was pegged at something like 10ms. I had my afr table set to 11:1 in that region and the VE table was @ 119%. I had the the the required fuel setting in the 'fuel settings, injector characteristics calculator box' set to 14.7:1. I'm thinkin GEEZ! I have 30 lb injectors and no reason to run that lean @ 8psi so after mulling it all over, I changed the required fuel setting to 11.5:1 and tried again. Now, I had no detonation and the datalogger showed ego afr in the correct region and pulse width @ 13 something ms. I did however, reduce the inj. open time to get it to idle good. I'm a newbee @ digital fi and am undergoing a huge learning curve on this. It could be that I have alot of my settings bass-ackwards but it seems to work for now. BTW, I totally respect your input and dont want to steer anyone in the wrong direction with this so please don't hesitate to correct me.

OK, I saw that I had a few people lookin but no replies so I asked my Grand National guru buddy the same question and he said YES you do need to set the required AFR box to your expected usage so it will adjust the injector pulse width accordingly. The part that confused me was the mega manual says to put in the AFR for the type of fuel you will be using and nothing about your target AFR usage. In my case it was 11.5:1 not 14.7:1 in case anybody is interested....

Should I set this required fuel AFR box to 14.7:1, or set it to my maximum expected AFR usage? I am using 30lb high impedence injectors and I noticed on Cygnus's msq posting, that he was using 45lb injectors and set his required fuel to something like 11.5:1. Is this the correct thing to do for boosted engines? I can't seem to find any info on this and the mega manual seems vague on this issue or maybe I really am a Dum-bass.

A question for you, I picked up a Dodge coil pack out of an intrepid for my EDIS conversion and it has three wires coming out of pin three on the connector. One is black ( i'm assuming it is ground) one is green and the other is bare. Do you know what the last two are for? or is this a really dumb question?
