New programmable ignition in design - TZ125 and 250

[DonTZ125]

This is still vapourware at this point, but I have a few thoughts about what I want to do, and I'd appreciate any comments or suggestions on what you'd like to see.

Planned Features:

Plug 'n' play with 4DP / 4TW / 5KE and 4JT
• No cutting, splicing or crimping
• Compatible with 'extra' pins etc on Kit and 5KE4 harnesses
• Ignitions for earlier models will be available with mating connectors where possible

o Connectors identified for 3YL, 3TC, 3LC
o Customer input needed to confirm lead lengths
o Compatible with AC-CDI charging coils on earlier models

• On-board Bluetooth
• Tuning software useable with PC, laptop, or smartphone


Ignition:
• 12 x 12 3D map, fully interpolating, TPS vs RPM
• Input switch to swap between Map1 and Map2
• 3-position Map1 adjust (points inside the curve; ie 13,500 point on 5KE WGP map)
• Offset right cylinder timing vs left
• Retard on knock; adjustable threshold
• 50% spark cut ("4-stroking") on closed throttle [ndwedwe]
• Override PJ to reduce knock (if cut) [dand]

Auxiliary Systems:
• Power Jet Solenoid

o On/off or modulating, 8-point curve vs RPM
o Input switch to change PJ maps

• YPVS

o Cleaning cycle at power-up
o Guillotine-type - open / shut at adjustable RPM (9000 per ’02 5KE3)
o 5KE4 barrel-type modulating YPVS - 10-point curve vs RPM

• Shift Light at adjustable RPM
• Quick Shift with adjustable spark cut time
• Launch Control with adjustable launch limit

o Prevents engine from revving past set point while clutch is pulled
o Allows rider to hold throttle wide open, concentrate solely on clutch

External Components:
• TPS – bolt-on, in design
• Shift Light – bolt-on to standard instrument bracket
• Quick Shifter
• Switch Cluster - compatible with YEC 0-7 Selector
• Launch Switch
• SD Card Logger - in design
• Knock sensor, mounting adaptor and processor module

Thoughts? Comments, rude or otherwise?

Sounds awesome!
How about a gear position indicator..?

Keep us all posted on your progress, this is great stuff.

Thanks for the kind words.

A GPI would probably be a stand-alone unit; I *might* be able to come up with a sensor to fit insde the transmission ...

Sounds like you've got it all covered and a hell of a task ahead.
The zeel had a feature with the tps where if you chopped the throttle hard (end of a straight) it would only fire every 3rd revolution. The rev counter would drop to zero.
As soon as you cracked the throttle it was back to normal. I recall it giving me a little confidence on my road bikes that you weren't going to lock up after a long straight.

If it was easy, anyone could do it - and there wouldn't be any money in it!

Spark cutting on overrun - yeah, I remember an article about the old RZ500s, and how they had a bad habit of that - it called them "the whispering death". This will need a bit of thought ...
