Did My TBS

[BrunDog]

800 miles, used the el cheapo Motion Pro economy tuner.

My only complaint is the marks are waaaaaaaay off. In other words, using a ruler, with the engine running, from the top of the Hg pool to 25 cm of Hg, the tuner reads a tad over 22 cmHg. Oops!

Knowing this, I marked off the point to tune to. Conveniently, #3 was right at it. #1 was 10 mmHg high, #2 and #4 lower than #3.

Checked the idle, got 'em lined up with intermediate revs, easy peazy.

I did notice that at higher engine speeds they vary again, but of course the engine is unloaded in this case.

I am going to test ride it and see if it reduces those little vibbys at 4.2k.

The only problem I see with this is making sure my kids don't mess with the tuner and turn it over!! :nono: :nuke: :scare2:

Oh, and also, that new switch I added for the radiator fan was readily put to use. I did the TBS outside in 95 deg heat with the switch on and the bike never left 2 bars!

Sweeet (IMO)!!

So do you wire the switch into the ground side or hot side to make the fan work?

ECU side of solenoid, ties it to GND. No high power switching going on here - the native relay does it as always.

The +12V side of the solenoid is automatically powered through the ignition switch. When the ECU wants to turn the fan on, it grounds the solenoid. My switch does the same thing. Beauty is that the switch cannot force the fan on without the ignition being on, and a low power switch can be used.
