Matt , the Ignitech coils seem to work the same as the RGV / RS250 coils.
Its a matter of matching the output circuit of the DCDC converter to the reactive impedance of the coil.
Ignitech have chosen one pairing , Honda another.

The perfect and obvious answer. Thanks.

Very helpful quick guide, there is some 2000 pages here, interesting indeed, but i'm looking for exhaust pipe discussion, the more physical the better. Do you have any suggestion? Thanks.

This thread is like a good show and tell dinner party where people put something on the table to share, ideas, talk, and laughter with friends.

Enjoying whats on the table is good and sharing makes it better.

Andreas please tell us something about your project.

Just for update, cleaned dyno roller and tyres. No slip on the way up. 2nd issue is I was watching the bike tachometer rather than the dyno one as I usually do. Not sure why, maybe just got scared as it was whipping up go 11,000. Actually that was a real 10,000 so a few more revs and my peak was recovered and drops. Don't want to go crazy over revving a big engine. (7mm stroked RZ350 with 72mm CPI barrels).

Happy enough tickle under 100hp at 9800 with the air box back on. Fine for a road bike in a diminutive 250 chassis.

100 rwhp street legal RZ250 look alike sleeper, very impressive.......

[F5 Dave]

Well looks more like an RGV250. . .

100 hp RGV250 is very impressive, I am both impressed and jealous as..... any pictures?

See what I mean about the old tyres

this is where the story got to with the Ecotrons 2S EFI system on my F4 Suzuki/NSR 110cc Bucket.

People have asked what am I doing with my new EFI system and why is it taking a bit of time? Should be easy to swap over, Right!, because EFI is EFI.

And I find it easiest to explain that I had written an EFI story using a foreign language (Ecotrons). Which as it turns out, does not work that well for high performance 2S's. So to change the ending of the story I need to use a different language, like the open source (Speeduino).

But to change the ending I first have to re write the original story in the new Speeduino language so that it reads the same as it did with the old Ecotrons one. When I have done that, then I should be able to change the ending to a more interesting one. Learning and getting proficient with any new languages takes time.

Boy, can I confirm! I spend most of my time between people whose language was conceived by seasoned sadists. I'm not doing too bad with German, but not a day goes by that I don't think how wonderful English is by comparison. You guys don't know how lucky you are.
Back on topic: you describe perfectly what it takes to switch from one programming language to an other. Initially the switch won't even improve the quality of the program; that can only come after utilizing the plus-points of the new language.
