Joejr915 Posted June 27, 2013 Report Share Posted June 27, 2013 What do you guys prefer pvl on stock ignition and why? For drags also what size motor are you running them on? Quote Link to comment Share on other sites More sharing options...
J-Madd Posted June 27, 2013 Report Share Posted June 27, 2013 Stock ignition on any size motor. Less of a headache. WHen a pvl starts acting up, you have 4 different components to test, and they may be bad even if they test good. WIth OEM it's easier to swap out parts. The pvl curve is also more flat, unless you get the programmable one. MOst of the guys that went to the pvl bandwagon a few years ago are back running OEM.

m671054 Posted June 27, 2013 Report Share Posted June 27, 2013 Still on the pvl wagon here. Cheaper than stock and run fine for my use. have one on a 493 cub and one on my 610 cheetah. i like the simplicity. Quote Link to comment Share on other sites More sharing options...

fappy'97 Posted June 27, 2013 Report Share Posted June 27, 2013 Also curious... Quote Link to comment Share on other sites More sharing options...
Joejr915 Posted June 27, 2013 Author Report Share Posted June 27, 2013 For those people drag racing did you have to regear when going from pvl to stock or viseversa. Or did you leave the gearing alone Quote Link to comment Share on other sites More sharing options...

SlowerThanYou Posted June 27, 2013 Report Share Posted June 27, 2013 We have 2 different ignitions mounted for testing this next time out. One is a stock cdi & the other is a Dyna. They will both be run with the stock curve & same advance in the plate. I'm curious about the results, good or bad. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted June 28, 2013 Report Share Posted June 28, 2013 Do you mean the dyna "stock" curve or the real one. Good scientific test vs the 2. Please post results. Quote Link to comment Share on other sites More sharing options...

The stock curve programed into the Dyna. Just wanted to add. Normally, I would like to get 3 or 4 runs of data from a test session like this. We will probably only have time for 2 runs with each cdi with the stock curve & the same advance in the plate. I already know then benefits/performance of using a Dyna ignition & using custom timing curves, along with the launch limiter. That's why we aren't spending much time with the test. So, take it for what's worth good or bad. This test will be more about Dyna's claims of better performance just from it being a better cdi/better or hotter spark. 1 Quote Link to comment Share on other sites More sharing options...
Joejr915 Posted June 29, 2013 Author Report Share Posted June 29, 2013 What do you set our timing on your 10 dmx for 300 and what for 1/4mile Quote Link to comment Share on other sites More sharing options...

That's what I was wondering also. Quote Link to comment Share on other sites More sharing options...
SlowerThanYou Posted June 29, 2013 Report Share Posted June 29, 2013 What do you set our timing on your 10 dmx for 300 and what for 1/4mile We are still a little lost on the DMX. It has only been to the track twice. We have never had very good results with the stock timing curves & additional timing in the plate with the cub motor. We started very conservative with the timing, using our cub gas timing curves. We start with 17*-20* of base timing. It slopes up to the highest timing between 22*-25* & we hold that for a set RPM range. Then we start pulling timing out to 8*-12* around our peak HP rpm. We found the cub timing was not enough for the DMX & started adding more timing. This will probably all change, because we think the stator was our problem. Anyway, the plan is to run the stock timing curve with +7 in the plate. This will be the setting for 2 runs with the stock CDI & 2 runs with the Dyna CDI. Then go back to our custom timing curve & use the launch limiter. So, I guess you could say we are doing 3 different test. We have only ran 300' the 2 times out. We hope to run 1/4 mile in the late fall. Note: The above test plan is subject to change, LOL! Quote Link to comment Share on other sites More sharing options...
