Red GTS1000 running MS Extra using cased MicroSquirt Day 8
Sat 27 Feb 2010 Filed in: MicroSquirt
Yet another attempt at a cold start, but for some reason I noticed the ASE Percentages is cutting out too quickly, so I increased cycles hugely in the ASE Taper dialog box. Didn't really seem to make much difference, but WUE is the key...this engine likes quite a bit of fuel on coldish 8ºC starts, but soon drops in richness requirements as the bike warms.

Red GTS1000 running MS Extra using cased MicroSquirt Day 7
Fri 26 Feb 2010 Filed in: MicroSquirt
Another day, another cold start, and still it doesn't run on after catching. At least the Priming and Cranking Pulses are doing their bit. I tweaked the WUE and ASE Percentages and it caught OK, so another day is needed to test these revised settings... Read More...
Red GTS1000 running MS Extra using cased MicroSquirt Day 6

Another attempt at a cold start...coolant temperature 8ºC...doubled the injection priming pulses (from 1ms to 2ms) and hit the button, quick fire on the button (that's an improvement) but it dies instantly. OK, so boost the WUE (Warm Up Enrichment) and mod the ASE (After Start ) Percentages, and hit the button again. Engine starts very quickly, on closed throttle, but dies again within a second...

Red GTS1000 running MS Extra using cased MicroSquirt Day 5
Wed 24 Feb 2010 Filed in: MicroSquirt
Another day and another cold start test, and it wouldn't fire, so I swapped back to the stock ECU and it fired straight up. I swapped the MicroSquirt in and with the revised settings it started straight away, but fast idle was about 800 higher than stock, and the conclusion is I need to look at my cranking pulse widths in more detail. The throttle response dropped off unexpectantly after a short time & then I realised I had run out of fuel... Read More...
Red GTS1000 running MS Extra using cased MicroSquirt Day 4
Tue 23 Feb 2010 Filed in: MicroSquirt
Since that last run day before yesterday, I have been reworking my VE tables and Ignition, looking at the Cranking and Warm Up Enrichment, After Start Taper and Percentages and today I uploaded the latest configuration. It started on the bike after further tweaks to the cranking and the fast idle was around 2200 and dropping gradually to 1100... Read More...

I hit the road at 15:30 and 2 hours later the 5K stumble was done and dusted. The engine revs cleanly from 1100-11000K and rips on the throttle. It was absolutely awesome...and I haven't even used the full capability of the MSExtra code... Read More...
Red GTS1000 running MS Extra using cased MicroSquirt Day 2

The throttle response up to 5000 rpm is very nice, but there is a sync issue after this. I am using the B&G adaptor loom, which has a signal diode on the crank trigger, but I was unable to swap it for a resistor, as I didn't have any. I just have to do some more work on the cold start settings and after start enrichments... Read More...
