I’ve just had a fun few hours preparing the Capo for its MOT (annual inspection) and one of the issues I wanted to get around to sorting was the slightly high tick-over.
For quite a few months now the idle has been 1,500 – 1,550 when warm – not enough to be troublesome, but noticeable. Problem is ….. I’ve plain forgot to do anything about it once the ignition was turned off! So today I dusted off the cable and charged the old ASUS notebook and plugged in.
Thankfully it was just as I hoped, the TPS (Throttle Position Sensor) was not at zero with a closed throttle. It was reading 1%. A tap on the ‘TPS Reset’ had it reading 0% and the idle was fine once again. So, the question is, have I got a TPS on its way out, or was it simply the fact that I hadn’t done a reset in 18 months ( 20K+ miles), something I used to do at every service. I’m hoping it’s the latter and will endevour to make sure I hook up TuneECU during all future services. Funny really that a tool I used to hook up on an almost weekly basis slowly slid to the dark recesses of the workshop over time.
Sometimes a particular feature of a piece of technology can drive you nuts – that itch you can’t scratch! Here’s my particular niggle with the Capo dashboard ……
Just imagine, it’s a nice day and you’re all suited-and-booted, ready to tear up the countryside on the Capo. You’ve pushed the ‘Set’ button on the dashboard to display the trip meter and all is fine and dandy in the world, later you pull over for a break and when you restart the bike – the dashboard has switched back to odometer! I know it’s not exactly the end of the world, but it is annoying. Why couldn’t Aprilia just code the damn thing to display on start-up what it showed at shut-down, many other bikes seem to do it.
So as part of the long running Mk2 dashboard project, the feature has now been incorporated!
With a little bit more code and a couple of extra wires, the dashboard now knows what was displayed (odometer or trip) at key-off. Then it simply electronically replaces a winter-gloved podgy finger and prods the ‘Set’ line to the old microcontroller a second after the board finishes its POST (power-on-self-test) routine. It also now reads the voltage from the fuel level sensor in the fuel tank, so that if the trip meter is displayed at key-off AND the fuel level changes from less than 15% to greater than 90% (approx. <5l to >20l refuel) at the next key-on, the trip meter will be reset automatically. If you don’t want the reset to go ahead, you simply make sure the dashboard is displaying the odometer before switching the bike off, now the reset is ignored.
Of course all this is well and good on the workbench, but in real day-to-day use – will it scratch that itch? Hmm, time and a few miles under the Capo’s belt will determine that answer……. maybe I’ll just end up with a nasty little rash! 😕
