We have used the Ignitech V 109 adjustable ignition system that comes with its software cables and stuff .
NICK is our 2 stroke expert here and he choose to be somekind of gendle when it comes to tickle with the timing advance after baseline set up , coz if you are crazy enough you could create a big hole in your pistons head really quick!
But yes even with the standart ignition map in the program the engine was much more lively ! And the costs are worth it .
That’s awesome, thankyou so much.
what coil did you use? And was there any dramas trying to get the program to recognise the factory denso crankshaft pickup sensor? I use a senior max evo with a dd2 barrel, I once had a rotax max crankshaft the we modified to advance the timing 10 degrees, and it made a big difference and gave me the bottom end back the you loose with a dd2 barrel, but the only problem with it was that it was still fixed and non adjustable
no dramas from the reading of the standard pick up sensor read from the program . we use the stock one . Nick had use Tobaki racing ignition coil . the red one with no problems , but ignitech makes ignition coil sets you can buy and use with this set up also
After searching different programmable cdi’s that can control my factory rotax evo electronic power valve I have come up with 3 options #1 RTD EMX-04 #2 ignitech SPARKER DCCDIP1 race #3 zeeltronic PDCI-12
I will update when I choose and purchase a programmable cdi
The new power valve on the evo works a treat, the Dellorto ecu/cdi unit makes sure that it’s opened and closed at the exact rpm’s, it uses a electromagnetic solenoid (part number 7.22448.08) and a one-way check valve to control the pressure, with these cdi’s I’ll be able to control the power valve still and be able to fine tune it to suit the tracks I race on
Yeah, I’m at a point now that I need squeeze some more out of the engine, a lot of people use iame kf1’s and rok gp’s but I don’t want to do down the route and I’ve proven that I don’t need one (I’ve won every feature race in the last 2 years) it’s a 2019 evo with a dd2 ss barrel with vforce v3 reed block, I do have a couple of barrels and I have ordered 2 of the new 2024 cylinders so I can have a play around with them. I’m thinking about trying a flattop piston with the head insert to suit it. a tad more compression and try different squish angles, we do race flat out the whole time so to much compression will sacrifice my top end.
We race on dirt ovals and I also believe that the intake/reed block area is too big on a rotax and I would like to possibly weld it all up and remachine it to fit a iame reed block or a kz reed block.
In Australia, we race on full size speedway tracks so mid range to top end is very important but also need toque to get good starts and out of the corners.
