Optispark Rule Rule Update

[Billy Nees]

The way I'm reading it, if your combo has a crank sensor AND a cam sensor then you can use a crank trigger. That's an awful lot of combos.

Billy , Maybe we should order a couple of the S/S hi zoot kits to get a discount.
Let's see ..got my credit card out , looking for a bolt on kit for a 1.9 Ford ....

Do what James did...find out if you can run one,or just put it on and see if they make you remove it.

I wouldn't run out and buy parts yet. There might be a clarification in the works......

Thats interesting. All optispark distributors have a cam sensor in them. The only time it's used is to run sequential injection and that is difficult to set up. You don't need it for batch injection. How do they intend to police this? This wasn't a well thought out rule change, as usual.

SECTION 11A: STOCK, ELECTRICAL:8, DISTRIBUTOR (Page 12)
(12/16/2021)
Any battery-operated, stock-type ignition permitted. Crank trigger systems
prohibited unless originally OEM equipped with crank/cam sensor (removed-distributorless
ignition). Distributorless ignition must retain OEM number of coils. See General
Regulations 8:3

Ya know, I've gotta laugh but under this vague rule wouldn't a distributor cap and a set of points qualify for a crank trigger?

Jon, don't give them new ideas...the next thing would be NHRA issuing EFI software packages limiting and controlling the performance of the car.
