ESE's works engine tuner

[Yow Ling]

I'd love to try one for size, perhaps when I'm down for the BoB. If you south islanders are still talking to me after I win the race.

Its a pretty long race for a go kart bike

[F5 Dave]

And for this old man too. But will make victory all the sweeter

Lozza, shocks are sorted ( I hope, I've ordered some off Walter, yss ). Yes a new pipe would be good just need time to sit down and build one. Wobbly will help. Barrel, well the original will do ( for now ) with some work. Remember it's not too far off the original ( older pre 1972, 33 HP engine ) cylinder so there is a lot more to be had. But I do want to cast a new " special " one, you know " spirit of the era " and all that, teach them to not recognize EFI as sporting.
After talking to Walter it is interesting as to how many others are ( in my class ) using supposed illegal suspension parts, the difference was I told everyone what I was up to.
Also got a young rider for the F9 this year so no more problems with an old slow operator.
It's a real shame, I'm going to have to find all my old carburetor stuff, you know, needles and jets and things and all that messy fuel every time I change it. I am leaving the variable valve in though.

The rolling green hills that your race on can probably handle more HP than the goat tracks we ride on. The orginal cylinder is good enough, you don't need a new cylinder................so that free's you up to make a F9 dry clutch for me 50hp would be easy, then the brake problems will start Big advantage of a new cylinder would be a nicasil coating and no liner
Needles and jets I could get you close with a 36mm Mikuni but I would still try proper pipe first. I'll email you my 400 pipe specs.

[Flettner]

Thank you Lozza, I would appreciate that. Just rung Walter, he said shocks should be here tomorrow or perhaps Monday, can't wait! Yes the clutch on the F9 is a bit on the small side. I use plates out of a 97 KX 125 (I think) and stiff springs. Clutch actuation is by a lever arm now as the plastic spiral thing is just rubbish, is now and was also in 1973.
Dry clutch? I assume for road use?

Well got the old girl hooked up again but just could not get the Beast to start, plenty of fuel going back to the tank so I guess the pumps working and there is spark and some small amount of fuel blowing out the Ball Valve inlet, wouldn't fire even with a puff of either, so flooded maybe???

This and some other things puzzle me, and when I find the answer I will post it in the EFI thread.



Puzzle number 1, why does injector 2 show some activity first and not injector 1.



The setup came with only injector 1 in the fuel calibration screen but I know where to find injector 2 (Val_Qstat2) and add it to the mix, but now, how to save it so I can see it in the calibration screen????



Because when I go looking for it to enter its capacity, I can see injector 1 (Val_Qstat) but I cant find number 2 (Val_Qstat2)???

Well I guess its par for the course when learning something new.

Keep in mind,, it´s EXTREMELY easy to flood an injected engine when first trying to map an EMS to start for 1st time.
As you often got throttle closed and haven´t got a clue how much fuel it needs.

I have setup a couple of racingmachines with haltech etc etc(4 stroke)
and what i learned to make it fire for the first time.
No fuel, open throttle a small amount.
then ramp up fuel from zero to when it ignites, try to get it to run with this throttleopening at first.

then when it´s steady at say 2000rpm with that very throttleopening.
Give it some throttle upwards and downwards and listen to engine, more or less fuel?
then try new areas, you will get a 'fingerprint' of what it needs.
shut engine off.
Fill in your values in complete map, let engine cool off, then start over.
actually, you might want to wait to the next day for a complete coldstart again.

And,, as a warning
You will spend hours and hours testing,mapping,fiddeling,swearing,testing,mapping ,fiddeling etc etc etc etc.....
But,, good luck!
It´s very fun and you´ll learn a lot!

Thanks SwePatrick .... I will have another go at starting it when I have plenty of time to just quietly play with it.

If you think it might be flooded just pull the plugs off the injectors and turn it. The 4-stroke Ecotron system tips in huge amounts of fuel at startup. There's a few variables that are dependant on start temp and then time after start but it's entirely possible that 15X the normal fuel amount is being injected at start and for around 5 seconds and then ramping down.

Good tip, thanks.

Yes I know where those variables are and I will have a play with them.

I think this is what has happened.

[TZ350]

Anyway I have found how to adjust injector 2



The first injector can be found under calibrations for fuel



The second injector is found under advanced calibration and you have to select it from the left side and add it to the right.



When its on the right side you select it, press OK and then you can change its value by double clicking it, editing then pressing enter to save.

Man, looking forward to this develop progressing. Keep it up TeeZee.
I've always been keen on a fuel injected bucket, so this and mikes project is very mouth watering.


North Island Series.
How about a side comp, battle of the teams (constructors championship)? ESE vs GPR vs Team Green vs team welly etc
Top two/three bikes home (points) from each team cumulated over the events.

I'll put a bottle of whiskey up (not Griff bootleg either)..

[Flettner]

TZ, are you in tomorrow? I'm up in Auckland so will visit. I'd like to have a look at ypur EFI GP if I may.

I'll bring my new cylinder for you to look at, a new concept, uniflow, but with a single piston. More port time / area than you can poke a stick through.

Keen to see that, I will be in at work 10-12ish what time are you expecting to be up this way? PM ed you my cell number.

Now you've made me curious....
