To get full access to the MT09SP logs collected by the woolich logger I set about decoding the Woolich log file. That allowed me to do my own analysis of the bikes data and investigate behaviour that's otherwise impossible to look at. I expanded the log decoder functionality to include filtering and adjusting the log files in order to remove entries that I don't want used by the Woolich Autotun...

After playing with the absolute ETV limits in a recent video I was finally able to get out and do some rides to test the changes. The result was that the maximum ETV values did increase and I can now get higher throttle openings in 4th, 5th and 6th than I could before. In addition to that I decided to take the bike to the drag strip and see how I went. The mt09sp isn't really suited to it due t...

My original prototype o2 sensor delete failed due to neglect (I didn't use a conformal coating). While i'm waiting for PCB's to arrive i'm trying another prototype this time using an ne555 timer chip.

Performance on a recent ride resulted in me wanting to change the throttle mapping for 4th gear. While considering what changes I would make I decided to look further into what may be affecting or in this case limiting the peak performance. Exploring ETV limit and the MT09 Throttle maps

Another low quality video about how I wired up the zeitronix AFR tool to the MT09SP The wires supplied weren't ideal so I modified things a bit. I know that there are claims that the o2 sensor only works at low load and rpm. That may have been true when they were first introduced and when the amount of storage the ECU had for o2 learning was limited. But these days the storage for the learning ...

Halfway through 2023 a new ECU version was released for the MT09. In canada it became a recall version but for the rest of the world it wasn't always on offer. I wanted to do a back to back comparison of the 2 versions. Early 2023 versions are -11 and -21 Mid 2023 versions are -12 and -22 I set my bike back to the stock 21 part that it came with and did some logging of engine braking. Then I ha...

Finding ODB2 readers that are guaranteed to work on a modern bike isn't easy. Luckily I was able to find one that worked and an adapter cable too. FOXWELL NT301 www.aliexpress.com/item/32800615952.html 6 To 16 Pin Motorcycle OBD Adaptors www.aliexpress.com/item/1005003057542200.html

So at every 10,000km (according to the Periodic Maintenance schedule in the service manual) we're supposed to check the throttle body synchronisation. Determined to do my own services I obtained a synchroking mk4 in order to allow me to do the job. According to every youtube video I could find it's a relatively straightforward and simple process. Sadly that's not true and there is a lot that is...

After many attempts at developing an 02 sensor delete to trick the ecu into believing that a genuine 02 sensor was attached I finally went for a somewhat smart solution using an attiny10. In this video I talk my way through the steps I took including the mistakes and so far things appear to be working.

Faced with a persistent over revving on idle problem I set out to determine if it was the lack of o2 sensor causing the issue. Many hours with a soldering iron and 3d printer and I had a test box allowing me to vary what the ECU thinks it's seeing from the ECU. From experience we cannot take any setting at face value (Disable Closed Loop... i'm looking at you) so this was intended to answer the...

While making small changes to the ignition map I discovered that MT09 tuners should never unify their ignition maps. It turns out that the unification of the ignition maps was the cause of my ongoing over revving issue at idle.

Just a progress update. It's a big one. There's a lot covered. If you've go this far with me then you know how I can waffle on. But there's some content there 0:15 Easy settings backup and restore and autotune settings management. 4:00 Reassessing my approach to Autotune. Was I too cautious? 6:15 More log data investigations 7:15 Improving my log file filter 10:20 Log decoder update relating to...

I've generally been pretty accepting of the "quirks" present with the woolich software. I set out to upload my maps to mapshare and promptly encountered some some things that genuinely leave me scratching my head in wonder. The expression "Warts and all" applies somewhat to this video. As much as I like the product for what it does there are limits to it and it's not constrained to the software...

So Woolich wiped the Autotune settings again. Time to discard any trust I had there and engure I have a backup of my settings so I don't have to remember what they were every time Woolich decide to wipe them.
