Other EPIC timing info 61X stator/flywheel

[RenoJenkins]

I installed an EPIC on my square nose a couple weeks ago and like the results. (thanks Steve) Using the more aggressive curve supplied with the EPIC the power difference can be felt, not a mind blowing increase but definitely noticeable. Certainly better than my previous setup of advanced stator and stock CDI.

I had read on here that the timing needs to be adjusted when using a 61X stator/flywheel but never saw any numbers on how it needs to be adjusted, (maybe I just missed it though) so I figured I would post my results. With the stator aligned to the stock settings timing was 2 degrees lower than the programmed curve, which wasn’t too bad, at least it was in the conservative direction. I used the timing offset feature in the software to adjust and it worked perfect. Also, having the programming lead was a huge help since you can program a flat timing curve.

Should have taken a picture of my setup, between my custom ground timing pointer and cut up old flywheel cover it was pretty classy! ha ha

Thanks for being so specific. I think I've read just about all the Epic posts on this and other forums. It seems everybody tap danced around the 61X timing issue, you seem to be the first one to actually express it in degrees. I had set up a 61X stator with a jetinetics flywheel and advanced it 3 degrees at the stator to cut down on future timing confusion. The jetinetics f/w seems to require diff. timing. One other time I had bench tested an engine just cranking it with a starter -probably not a good test- and needed about 7 deg more advance for the (oem) 61X setup

Making the adjustment with the stator is probably the best way to go, like you say cut down on future confusion. Once i saw everything was working though i just wanted to hit the water! ha ha 2 degrees vs 3 with the jetnetics flywheel is pretty close, maybe just inconsistencies between stator alignment? Thanks for chiming in, I am curious to see what other peoples results have been.

Every one we have set up with a 61x stator was different and each had to be verified
and than adjusted with a flat timing curve, We set the stator on the mark and use the timing offset feature to get it right. no issues so far

If you are running an aggressive curve on a 61x stator I would for sure set it up with a dial indicator , pointer and flat curve, or risk disaster

dial indicator piston position calculator can be found here

I use 15 deg

be sure to use the latest flash for easier starting

Interesting they are all different, thanks for the info.

Dial indicator and flat curve is what i used, except i marked top dead center and used the timing advance knob on my light. Cool calculator on the website.
