Thought some of you may find this interesting as I get asked quite alot about the benefits of a programmable ignition Below are some dynographs of the same bike (350 YPVS F2) after several upgrades The first graph is of the bike before and after an ignitech was fitted, you can clearly see the gains to be had if it is set up correctly  The second graph below, is how the bike looks now compared to when it was tested in completely stock trim, the changes made to the bike include a set of pipes, rejetting, some porting work and the ignitech fitted  The owner recently rode the bike after it was finished and reported it was a significant improvement after the ignitech was fitted and rides really smoothly and nice now Hope you find that useful |

Ignitech's are the future

Blimey, looks good. I'm thinking of going down a similar route once my F2 is alive and run in. I don't want a mad power band so thinking of Allspeeds as opposed to real expansions, stage 1 porting (just a tidy up and slight mods), rejet and did think about an f1 ignition, but it looks like the Ignitech is a better option.
I saw a post mentioning Banshee coils, is this a proven mod? I put a set of modern coils on my a/c 350 and the different was amazing ( not banshee ones though).

yeah, modern coils make a good improvement, the coils called "banshee" are just a label really, no such thing exists TBH, just a modern pair of coils make a good improvement, the ones I stock and use have a smaller foot print than the orange ones people fit and fit on an LC, F1,F2 etc no problem

Hi, How much for a pair posted and I assume straight replacement to an F2?

you need to either make a loop loom up (easy 2 wires) and also need a couple of brackets to mount them on (which I am out of at the moment) but are easy to make, I'll try and sort a p[hoto out for you so you can see what I mean, I'll send you an email with price and details et

that's good sensible power delivery that do you get as much on a lc?

More gain than the zeel ?

Someone is going to need regular crank rebuilds I would think  |

what tune on barrels was it dave ?
i take it they are top end revs tsa pipes ?
great results mate
if you get one simular but with a midrange tune and pipes will you put 1 on top of the other please
just to compare lower down rev range and torque curve as well ?
thanks you .

not sure on make of pipes, looked nice though in stainless
I am looking to do a zeel vs ignitech at some point on the same bike, I am expecting identical results give or take, but will be interesting to compare them from start to finish, so ease of fit, ease of setting up, cost etc

Dave, am I missing something in the two graphs, as the baseline in the second graph is a lot lower BHP than in the first, which makes the power gains over the first look bigger. Can you put all three runs on one graph?
The ignitech looks like a good mod, what about if you want YPVS Control, are you stuck with going for a Zeel unit?
Its great to see what adding just one thing does to the power curve. Sorts out what is worth spending money on.
Keep up the good work and thanks for sharing your findings.

yeah I can do that, overlay the 3 graphs
The ignitech is controlling the powervalve as well as the ignition, that is where the gains have come from by being able to sync the 2 up and get the best map for both the PV opening etc and the timing of the ignition

Someone is going to need regular crank rebuilds I would think Mark, crank will be fine, unless its kept pinned there everytime its ridden ! My track bike went higher than that and was regularly up there and thus far has not had anything done to the crank |

Does the ignitech replace the standard cdi unit or not ?,
I am putting a ypvs in an lc and would like to use the 4lo loom, what does the ignitech system consist of.
Would I need the ypvs cdi & controller?
The 31k engine I bought has a 4lo stator fitted (movable backplate) will this work with ypvs electrics

Yes it replaces the cdi and power valve controller , generator is only used for charging battery so should be ok.

as "Horace" says, yes it will all work - after all he should know as that dyno graph is his bike !! |

He has always told me the zeel is easier and more accurate to set up compared to the ignitech. i will be watching this thread closely. I have made my ignitech plug and play. I was a little disapointed with the results it gave, but my bum dyno does feel the difference when i switch from one to the other. |

Hi Al, sorry I don't share any of my maps or settings as the way I set the ignitech's up is on a bike by bike basis and I use a different technique to what is specified by ignitech or done by most people, so unless I also give you how I time an engine up and the other stuff I do my maps will result in your engine blowing up most likely. Some people have nicked my maps and settings from bikes I've done without understanding that and knackered their engines !
Its taken me nearly 5 years of testing, playing and developing to get the iggy's to do what I want, and I am not prepared to publish that, sorry, the other thing is that squish, compression ratio, exhausts, reed blocks, inlet trac length, stator, flywheel etc all affect how I set the ignition up, so very few bikes have an identical map, I reckon if I looked at all of the maps I have, very few would be the same

Out of interest (assuming it's not a trade secret) how do you set the spark timing safely to ensure you don't over advance and hole the pistons? |

Hi Phil, I use the dyno to tell me where the limits are, too advanced and you lose power, too retarded and you lose power, once you have found the range for a given RPM then you can find the sweet spot at that given RPM |
