I have one, but it's not the digital version. Evidently I bought mine about a year before this version came out :/ For what it's worth I like mine, it works but has no adjustment to it

Do they make the non digital style still?

I was looking at the Davis Unified Ignition Dyna-Modules 000222 also

The reviews for that one are great.

 

[Streetbu]

No. Mine has got to be at least 15 years old...

 

[TURNA]

Wow at least it lasted!!

I've been looking at the very same items. I'm tired of the cheaply made unreliable modules of today.
Maybe I missed it, but I'd like to see a Davis HEI tune up kit. like some of the other kits offered.

I have a accel one works great. Had it for around 10 years or so.

I think it is hard to beat a GM 4 pin module with a HEI ignition. I have put a bunch of ignitions on oscilloscopes and seen the patterns and outputs.
These include MSD, Jacobs. OEM's and others

That's why it still works great, it's old. The junk made today fails quickly. At least that's been my recent experience.

Mine also lasted 15 years, same thing no rev limiter but looked similar. I didn't put heat sink compound on it the last time, probably what killed it. I like Ignitor 3 module, it does start quicker and run better but have killed two of them.
