ZEELTRONIC PDCIS-Y62T TUNING

[BupBup]

Trying to get my Zeeltronic ignition dialed in for my ski, but have never tuned anything. I’ve had issues with getting max rpms out of the engine, and would like to have a little more power at the top end compared to what it’s at now. If someone is willing to walk me through the zeel program and let me know what I need to do, I’d appreciate it. Don’t really want to send it off to get it programmed, and I’m perfectly capable of doing it myself. Have the cable and a computer to do it, just need some guidance. Thanks

Engine Setup:
-701 61x case with porting
-ADA girdled head with 40cc domes running 91 pump gas
-84mm bore with Wiseco pistons
-single 46mm Mikuni
-Riva Red pipe
-61x electronics
-MSD coil
-lightened stock flywheel
-9/15 skat impeller with 12 vane 144mm pump

Just run the Wax V3 curve.

There’s a few things to consider when it comes to finding the most peak power. If your exhaust port is low it will feel like the power goes flat as the ski accelerates, especially with a low pitched impeller.. The zeel ignitions advantage is being able to advance timing a lot at low rpm for better response. At peak running rpm the timing advance should be a little less than stock for pump gas. This setting can vary depending on the head design and squish velocity. Fuel quality and carb tune are the limiting factors. You can advance the timing a little more with the carbs top screw set rich of peak rpm. Otherwise more high rpm advance will melt a piston.
