What Have You Done To Your Tdm Today?

[Catteeclan]

Started to investigate the feasibility of making an engine braking control device, by (hopefully) defeating the fuel cut on overrun which is coded into the ECU

 

I want to make it a universal fit device, not just for TDM's. Hopefully any bike with low side switched fuel injectors, and, 3 wire stator/generators can be catered for.

 

Step 1 has been to create a reliable digital RPM signal from one of the phases of the stator.. Not as easy as I thought it would be but I've got it to work today.

 

The idea is to make it easy to install, and negate all the difficulty created by different types of crank position and cam position sensors available on different bikes

 

The next hard bit is going to be to make it self learning. What it should be able to do is monitor the injection system and capture the injector opening times at each RPM at minimum load, and then when decelerating generate replacement injection signals, hopefully with a 3 stage control, of full engine braking (as standard), 'some' engine braking, and 'minimum' engine braking. The minimum setting ought to emulate a carburetted bike, and eliminate choppiness at small throttle openings.

 

 

Watch this space !

Clever stuff, maybe a bit of exhaust crackle off throttle too
