ESE's works engine tuner

[teriks]

Ive been using engmod2t for a little while now and initially though there were limitations in what it could do but now realise that i'm the real limitation... there are so many ways to measure and input data and its extremely hard to know if you're doing it right...

Im guessing the only way to tell is test with a dyno and compare results, then alter the way data is entered until dyno results consistently equal sim results...

Are there many engmod2t users on KB? might be worth starting a thread asking/answering questions.

Here's another user being a limitation of the software. I would be very much interested in such a thread, although I might not have much to contribute with myself.

I'm sorry I couldn't resist, especially as our overseas guests may not get the humour...

The TZ750 is just a pair of 180 cranks joined in the middle, so it fires in pairs.
Makes the ignition just a 250/350 setup with a pair of double ended coils running dead spark,Yamaha always went for "easy".

Im happy to help people with EngMod 2T as long as its a question on the forum, too much time/effort in PMs for the info to go to one person.

No slight on you Frits at all re the Honda winning in 250GP the last year, I was just pointing out that the Aprilia was developed to the very edge with super clever ideas and implementation,
but the Scott Teams Honda wasnt that far off with only a little help from the factory in trick parts etc.

Thanks for the offer wobbly!
Although I think the stuff I'm dealing with is a bit off topic for this thread, 6.6cc glow ignition engines.
Ill just stick around absorbing all the good stuff, wont have much to contribute with re. your huge engines

Frits would know a thing or two about them MB40's thoug.

I agree with Wobbly (I usually do): there is no money in paper books on two-stroke technology (there is little money in paper books period, unless you happen to write Harry Potter stories). But you'll find a lot of present-day info in forums.
ESE's works engine tuner is a good example, and of the numerous other forums that are 'open to the public' I would recommend www.pit-lane.biz. It's French-based, but yours truly and Jan Thiel are allowed to write in English (and I post all my photos in Dutch without anyone noticing).
A good starting point would be here: http://www.pit-lane.biz/t117p246-gp1...es-aprilia-rsa.

My there is a lot of good stuff in there & the bonus that it is in english so us colonial offshoots on the other side of the world from Europe can understand it. Thank you so much for opening the portal to view this as we would never have looked in a French site (though I see a few old faces like Seb4lo).

Now that Rob has put a link to pit-lane.biz (my almost secret place for all things techo), I'd encourage anyone who loves race bikes to check it out. Its a French site so you'll need to use something like google translator (which can be amusing) although Jan, Frits and others do post in english, those clever Europeans tend to speak more than one language which does help. There's all kinds of super cool technical info on most racing classes plus pictures of just about everything. Enjoy!

We really are privileged to have so many of the pitlane contributors watching and contributing to this thread, with their input (and Wobblys of course) theres absolutely no reason 2 strokes wont return to dominate buckets.

Its an industry thing, and can only be done by those in the know, and that also have lots of experience ... don't you know ... Yeah Right ...

Ermmm, polished the ports and raised the primary compression .....

I managed only a brief look at the Pitlane thread with the interview but firstly amazing pics. I was always intrigued by the rear disk engine but more importantly the drive. Now after seeing it (The early version I realise the later is different). I guess it owes a fair bit to the Koing at least in conceptual design.EDIT I have had a longer look. Pure gold and I am only at pg 18 2 stroke institute my is that so familar?

I spend a while looking in the Kaaden thread again great pics.
I thought you might get a kick out of the Alfred Scott bit I postedhttp://www.kiwibiker.co.nz/forums/sh...post1130150906.
The story below it, is the interview with Kaaden himself he seemed real sincere to me with how it all happened.I realise you were quite scathing of his influence.
But in here he certainly to me seemed to atribute the designs to the right people.
I seen the DR Joe bit posted from a exert from one of my other inspirational figures. Phil Irving I didn't expect that bit of how the copy of MZ worked.

I am guessing MR 4 stroke hasn't read the Pitlane thread yet. The two stroke is not quite as dead as you have been Mislead to believe MR Ban

That pitlane thread is brilliant, its great to see some amazing minds still working on 2T technology. Makes you wonder how much other stuff is on the net in different languages that we might never find as english speakers.

I reckon if anyone bothered to collate all the info from here and pitlane you'd have a pretty comprehensive and up to date 2T manual.

I love 2 strokes especially the peaky, violent MX engine's of my youth. And my old gt50 of course the first bucket way back in 1987. I also like playing the villain 4 stroke guy. Gives you someone to focus all the energy towards. Lets see some action on the track. I'm a bit worried some 30hp 2 stroke will just smoke us all at the GP, but we will have to wait and see. Its great so many talented people are willing to share there expertise and knowledge. No that common in motor sport really. Especially the pinnacle class's of F4 and F5.
