You should contact Craig @ Accel tech line (248-380-2780) to make him aware of your situtation, He may give you some helpful information, but if nothing else at least they will be alerted of another issue.
Did you do your own install or have an EMIC dealer do it?
Have you contacted anyone associated with Accel about your problems?
I have been told that some systems with problems like ours have been corrected by switching from sequential to staggered batch.
The strange thing about this is i have also been told that the DFI system will ignore the cam sensor signal over 3000 rpm (staggered batch does not require cam sensor input) This seems like two contrasting statements to me,but i'm no electrical engineer either.
Good luck!

Hmmm one of these days I should try taking my lil hydraulic motor up to 7400 and see how the ignition does. Allen remember how you were talking smack about how the Gen7 was going in Gordon's car? 
I guess my FAST is not so bad after all. (I am running an FMS cam and still consider Allen a friend even if he is not running a FAST).

and your FAST will prob be fine. At the time,my customer and I decided on the Accel since it all hooked up to the factory sensor,while the FAST needed an EDIS box and crank trigger.I never could seem to tell any difference between staggered or seq. mode

The Gen 7 is going into my car as soon as it gets back from Sikora. The FMIC came in as well. This never ending project should be wrapping up in 2-3 weeks. Now placing bets on the Final #s
My car wont rev much above 6400-6500 rpm's So I dont think Ill have a problem.

had one of the first gen7 lt1 systems,beta test the ls1 system,and even testing a newer ecm and software as I speak...If thats not enuff I do R&D on the lt1 and ls1 cam line and valve train for Crane...so Dale is a good tuner KUDO's I posted here to help since I am a EMIC also,surely wasnt to measure who has the longer johnson... I was only offering help and try to rectify thier problems...Please by all means since hes such a large dealer for accel ,tell him to post up or was you meaning all along dfi as in f.a.s.t. dealer,because thats what it seems your pushing here?????? Whats Dale running lately just curious??sorry for getting off topic...

Thanks!
Thanks!
All the mechanical work is done, Now we have to wire in the E-Dist box and reconfigure the software set-up.
Wer'e heading up tp Pocono for the cup race today, Hopefully be done on Tues. then we'll see how this puppy works. We'll let you know!

so,we are having issues with the gen 7 at over 7000?thats just great.good job accell.i have a idea for accell,how about an instruction book for the kit?that would be a good start.but wait,that would mean that someone would have to know how to type!maybe thats whats taking them so long.good help is hard to find. 
i think i will just stop my rebuild untill this mess gets figured out.the cam i just had installed goes to 8000!another season shot to hell.

It does not missfire, it shuts off.
I have data logged this with the Gen 7 & with my Racepak data aquisition system, the tach signal actually disappears when this happens.
Personally i am sick & tired of doing R&D for Accel,
I will figure this out but its going to get a Fast E-dist to fix it.
Thanks for your input, God knows i could use it!

my car does the exact same thing as above, but ONLY when i have the stock tach wired back up spliced into the dfi harness to the cam and crank sensors... when i unhook it again it goes away.. so i have left it unhooked for now. i'd love to hear the root of it... i was eventually planning on trying 2 new sensors, soldering the connections and shielding the wires but i think i am reading here that that does not help

Like I said before this thread is not intended to be used to bash the Gen 7 system, we are receiving lots of assistance from Craig at Accel and Joe has been so helpful helping us troubleshoot things. No thread hi-jacking please

Your tach should be wired to pin 16 @ the ign.control box (spliced)
This is the tach output.

brracing. i am talking about my stock tack. i know the exact wire where i can get an aftermarket tach signal but it does not work like that on our cars.. the output from dfi is 8 cylinder and ours fires like a 4 cylinder or something. to that effect but thanks for the help. or do you know this and i am missing something?

Sorry, from your post it reads like you were wired into the cam/crank sensors, If you want to retain your stock tach (inaccurate) i'm sure you could reverse engineer a convertor box to double the sig into the factory tach so that it would read properly, maybe Harlan could build one for you
I personally would not use it for racing, seems to have a second or so delay before it comes even close to actual.
If you require any help with the wiring let me know.

This thing is huge though, i don't think i would want it in my daily driver either. Does the circuit for the shift light have continuous signal or only at set shift points? Possibly tie in there?
Now i'm curious, i'll see if i have a good scematic of the instrument cluster.

this is a new problem of mine
http://home.comcast.net/~deezuns/ignition.WMV
this is not the rev limiter or the two step its just random loss of spark (seems like) at random rpms.. it doenst always do it, but it did it 4 of 5 pulls on the dyno... and seems to do it about 50% of the time on the street.. but has yet to do it at all at the track (fingers crossed) it seems to be getting worse.
i have the dfi log if anyone would like to help out... craig at dfi got sent the log files and the vid link just a few minutes ago
