I'm thinking about building myself a digital advavance for my 77 308 gt4. I have a single twin distributor with 2 coils to be driven by 2 MSD6A and will lock the mechanical advance. The target will be: - points driven (by now!) - retarded startup - pc programmable advance curve - 2 advance curves in car switch driven - rev limiter - may be single point switched I think it will work as a digital advance for any setup (stock too). is anybody interested and available to support, especially for advance curves suggestion, testing and pc interface ? Bye, Alessandro.

More than happy to help if I can, I have the Black Stalion ECU and various curves, some good and some not so
I have been working tonight .... Here is the hardware: i will use a different controller, and may be throw away 2$ and put 2 mosfet in output so it will stright drive sock setup (without MSD or whatelse). Doesn't anybody will help for testing ? ( i don't have anymore a test bench ) I'm not in business and will share the project on the forum, mostly deliver as open source. Thanks a lot for the answers, i'm very happy to see and use tested advance curves ... Regards, Alessandro. Image Unavailable, Please Login
alessandro, good job. always nice to see someone take on thier own projects. it looks as though you know your way around a circut board. if so we mondi owners have a severe need for an updated fuse/relay board. up for some hard work?
Well, my real occupation is real time software design. I also partecipated to a european research project (those one used to spend administration money) to develope a common engine control platform involving many manufacturer (BMW, Mercedes, Iveco ...). Really don't know what are you talking about, will you pay ? j/k course. Alessandro.
WOW! cool, not to highjack your thread buuuut. we mondial owners have a bad need for a new board to handle the amps and relays, fuses and wiring. right now we suffer with melted boxs, fires and blown fuses. the mylar stacked circut boards they used are horrid. a goo 'ol solid state board and connections would be great. this has been attempted many times in the past but never seems to move beyond conceptual design. i think we may have a loaner board floating out there for reverse engineering. cost has always been an issue for manufacturing from what we've heard. one day, one day the dream will live...
On my USA carb 308, with 8.8:1 compression: I trial and errored my way to 15 btdc static, 32 btdc all-in at 3000 rpm. This is not very aggressive in my opinion, and there is no need at all for starting with retarded timing. This was done by substituting springs and stops after converting to perluxes fired out of one of the two distributors. The difference in way the car runs and drives, especially around town, is phenomenal. Half of the benefit from Perlux, half of the benefit from coordinated advance curves, and half of the improvement from the aggressive timing curve. It is definitely synergystic. I use Chevron Supreme, but I bet even regular gas would work because of the small open chamber. There is no hint of detonation. If you are going to use MSD's, I would just use MSD timing computers. And always use an MSD 6T, not a 6A. The 6T is a much better product, for a little more money, and is forward compatible. The 6A is stagnant. Jay
If you don't hear it, it doesn't mean it never happens. One of the main goal of the research project i partecipated was to design a new kind of sensor to detect it listening at motor vibration. You could have a torque loss in the range 2500-4500 and should feel it climbing mountain using high shift. But will i have to install 2 of them ? Too late, ordered MSD6A last week and i am waiting for it from USA. Reading from MDS site, i decided that MSD6T do behave as a 6A but is "more stressable". May be i was wrong. Alessandro
Hi Alessandro, I think you should add some NVRam so that a PC interface can be used to store new curves without re-programming the PIC. I can help with the PC end (using .NET since it is already on every Windows PC). My time is somewhat limited between now and mid October, then available again after Nov 11. I assume you will provide a serial interface for the PC connection? Gerrit
The hardware board is ready for pond, but GT4 has gone ! Yesterday installed MSD and discovered there is no oil pressure. It was a fraud from a friend since sixty years. Any good lawyer out there ? Bye.
