I have Link G4X Fury that I want to run on my SBC V8 and I'm trying to get my head around these things and it might sound kind of silly but I cant really find the info I need.
I have 2 distributor´s one is a fancy MSD 8394 digital E-curve "ready-to-run" dizzy with adjustable timing curve, rev-limit and such. That came with the car/engine with a MSD blaster coil and a holley carb.
The other one is a GM Vortec distributor, which has a cam sensor and is non-adjustable or has locked timing.
Iam thinking I could simplify the setup plus save some money using the vortec dizzy and the MSD coil using the G4X Fury so I can use less outputs compared to doing a coil-on-plug type setup taking all the limitations in consideration off course.
But how does this actually work?
I read you connect one ign. wire to the coil and then I guess the cam sensor like normal and a crank sensor(Also using a Vortec-style setup) but do I also need a igniter module in this case or is that it?
Which MSD coil is it you want to use? If Inductive (like a conventional Blaster 2 or Blaster 3) then you will need an igniter. If it's a smart coil (like this one):
Then you can wire it directly. And if someday in the future, you want to use one per cylinder, you can just buy 7 more and wire them up.
You configure the ECU to use one ignition output (the same one for every cylinder), and use the distributor to send the spark to the correct cylinder. You will need to "clock" the distributor so that your complete range of timing is supported. So check with a timing light with the timing at max retard and turn the distributor until this just stops firing then back it off a bit. Then check with more advanced timing to make sure you can still achieve that (ie, you weren't turning the distributor the opposite way).
As David said, under LINK's description for "Ignition Adjustments", here - https://dealers.linkecu.com/G4X-FuryX - there shouldn't be a problem.
With the distrutor, as David also said, the rotor to distributor cap relationship is going to alter as the timing alters, this means that you need to "phase" the rotor to the cap so the two are together as much as possible - if an overlap isn't passible through the full range, I'd suggest biasing it so the gap is greater at the low rpm side, where there is less load on the ignition, this is a good guide to what I mean - https://www.youtube.com/watch?v=aWMlNwGW0tM - but with electronics controlling the timing, and a fixed shaft, you don't need the adjustable rotor as you can simply rotate the dissy body to maximise the overlap.
The coil is a conventional Blaster 2 coil, which would mean it needs an igniter but I think I just buy an smart coil like a AEM coil instead.
Or is there a simple igniter for this type of stuff, lot of the MSD ignition boxes have some adjustment build in but I want the ECU to do everything.
Looking at the vortec distributor it doesnt have much if any adjustment in it, the body have a little but considering its made for a factory electronic ignition setup it properly is correct? or I will find out shortly :D
Thanks guys.
