  • Quick video on how easy it is to swap out a 40 year old technology HEI distributor for a new one that you can tune with a smartphone. No weights, no springs, no vacuum can. no extra wiring. Built in rev limiter and kill switch that you can operate with your phone.

Seems with the computerized module a knock sensor setup would be a good addition - also, do you make this for small block ford as well? I have a forded HEI and love it and this seems like the next step.

    Stumbling block..? If your engine is old and has no visible timing marks, users may struggle to find and set that mark on the distributor body prior to removal. However, the rest of the process and the product looks ace. Going to your website now. Well done.

  • @DumbCarGuy
    @DumbCarGuy ปีที่แล้ว +1

    Makes me wonder if you can use this dizzy in any 90's ford 302/351w EFI after you do the full egr delete where your timing is a bit screwed up afterwards with possible pinging and such. The huge issue is that the eec keeps advancing the timing because of the lack of egr signal. Any thoughts on this? Have you heard about what I'm talking about? Hopefully I will get a response.

    • @thisisyourcaptainspeaking2259
      @thisisyourcaptainspeaking2259 ปีที่แล้ว

      Why not run full egr or a blocked (plugged passages) egr valve?
      My later gm obd 1 cycles the egr during deceleration and measures map pressure to confirm egr operation. An egr delete (or blocked passage) generates an egr code.
      Also, is your tranny a 4-speed auto with lockup torque converter? Cruising in 4th you need lockup working, else too much heat is going into the fluid from converter slip.

    You set your max advance at 34 degrees but when you ran your rpm up above your 3000 rpm "all in" mark your timing was way above 34 degrees and climbing still as you went past 3000. Is it adding 34 degrees to your initial 10 making your max advance 44?

    • @Tschida2004
      @Tschida2004 3 ปีที่แล้ว +1

      Reads the RPM signal and determines from your table where it needs to be @ WOT. Same as mechanical advance adds it with more engine RPM. This works the exact same was as an OEM Distributor it is just a lot easier to tune your timing. No more springs weights or vacuum canisters.

    I have a 1990 Lincoln Town with the Windsor V8. Looking for tune-up advice, how to get the best fuel efficiency. upgrading does sound like less maintenance but questioning ROI Return On Investment? btw the car has sat for 8 years and running well on warm days. but if I don't let it warm up 20* F or colder and try to drive off after 10 min it seems rough until it gets to operating temp. also after 45 to 1hr idle to op temp. it will kill the motor most of the time when I change gears R or D. I haven't noticed during warmer days dying during gear change but I have only had it for three weeks.

    Could it be possible that I went a tooth too far when I inserted my HEI Progression distributor? It seems to idle too high. I know other components can effect this but I am starting from scratch on a sbc chevy 350 with a Holley 4150 Carb. I've set the carb up the way many of the TH-cam videos said to. On a cold start up, do I just rev the engine up to 1200 rpm and turn the distributor until the timing mark hits 10 degrees BTDC? Or do I need the let the engine warm up to a certain temp before I line up the 10 degrees BTDC?
