Crane Hi6M ignition
 

Has anyone had any experience with this crane ignition system? On the CraneCams web site it looks like the Hot Ticket when compared to others. Multiple ign curves, adj. rev limit and more. Ironman.

I have one on my 555 Merlin and think it is great. So far 80 hrs and it has been very dependable. I'm using it wit ha Thunderbolt IV distributor, but with the Merc module disconnected running the HI6M advance curve.

I just bought 2 of them. They aren't installed yet - sure look like the ticket though.

Bobl, did you modify your distributors like they recommend in the tech sheet?

I had 2 on my formula running built Hp 500's, best ignition out there. Never a glitch. The rev limiter worked perfectly when I scatered a drive. I did not use any advance curves and had the distributor locked at 36 degrees. Below 2000 rpm the multiple spark function actually ranges +/-20 degrees so it would fire the cylinders at 14 degrees without requiring an advance. Just remember, timing light will be useless below 3000 rpm. I used their coil too and had to use an MSD tach adaptor for my tachs to work.

Where can I order one from at a reasonable price? Thanks, The Ironman.

They are great!!! Summit Racing was the best pricing I could find. Use their first 3 digits to indentify Carne products and add the Crane number for princing. they stock it.

Cignificant, yes I used the pattern they included and changed the phasing. I've done 2 of them and they work perfectly.

So is this just a plug and play install or do you need the tach adapter when using a VDO tach? Is there any real performance gain or does not loading up the plugs at idle enhance the overall performance?

What distibutor mods does Crane recommend?

Ironman, the best price I found was Doug Herbert Performance. He has to special order them, but I got mine in less than a week. Their phone number is listed here..

Tim, that spec sheet is for the auotmotive unit (HI-6). The spec sheet for the HI-6M is at..

The rotor phasing of the Merc distributor has to be changed. Looks easy enough. I've decided to use Mallory distributors, so I won't have to worry about it..

One more question will my stock tach still work? And thanks to all who responded I have decided to use the Crane over the jacobs or msd. The Ironman.
