Hi All,
As said on another thread, I had an excellent test session this morning at Boyndie drome Kart track - dry, cold, windy but the sun was shining and I was driving the car for the first time since Loton last September - 11 months ago!
Getting back to the sequential/COP settings and getting it working better; Well, I trawled the 'net on anything I could find regarding injection timing and it's relation to engine speed and load.
With this very sketchily-gathered info, along with playing with light loads/revs in the garage and monitoring lambda I've compiled a 14x20 injection angle map;
On track, it worked great - and doing a back-to-back run with the old batch/wasted-fire setup I couldn't feel any discernable difference. From what I've read, it's likely to only make much difference at low loads/low revs but more to do with economy/efficiency than any power gains.... My injectors are maxing out at only 60% duty so the theory says that I may see an improvement, but doing the maths, by around 5500rpm it shouldn't matter any more.
The proof is in the pudding, and only another trip to the dyno will tell for sure, but its certainly seems to be running very well.
Something else I fiddled with was the "Engine start fuelling" map as I usually had to hold the throtle open for a couple of minutes once started, before it would idle on it's own. I reduced the numbers massively (based on trawling the start maps of all the other DTA maps I could lay my hands on) - and this morning on first start from 10 degrees cold it ran all the way up to temp from start without touching the throttle and without faltering/stuttering so a real win! For info, here's the map I ended up with;
