aftermarket ignition

[daveyoh]

anyone running any aftermarket/programmable ignition/powervalve controllers?

if so, what are they, and how well do they work?
thanks
dave

(almost finished mods to my race 3ma. will post pics/info when done)

Hello Dave,

I do use the Ignitech race on my 3ma and it works great.
(Me to building a 3ma race, only the building is not going as fast as a want too)


You have a lot off options, you can controle everything.
you can control the airjets if you want, or if you mounted a electronic powerjet can control that to.
shiftlicht but all so switch between two ignition curves etc etc.

Fotis has one too, if you like some details pm him. He can tell you a bit more than me.

i ended up ordering a zeeltronic unit with a quickshift and a switch for switching between the ignition maps.

it arrived in the post today and looks very good
just need to get my bike back together so i can install it now.

do you have any good maps that you wouldnt mind sharing louis? or any recommendations?

i figure i'll just start at the standard map and change one thing at a time and go slowly, and record everything that i do with it and i should get some (hopefully good) results eventually

Hello Dave,

I had 55 hp on rear wheel with this curve, with standart exhausts

It is almost a standart curve only its started a bit higher at 28 degrees.
Take your time and do it step by step
Can you controle the air jets to?

[daveyoh]

hi louis

here is a link to the features of the zeeltronic unit

http://www.zeeltronic.com/page/pdci-20V.php

it has power jet outputs, so i think i can control the airjets with that? (do you mean the VAJ system?)

is that the same curve the whole time?
with the zeeltronic one you can have different curves at different throttle openings

[louis]

Hello Dave,

I think you can use the power jet output for the airjets (yes i mean the VAJ system)

The curve you see is the max hp curve, i do not use the Tps sensor.
I'm not looking fore more power in mid range, I'm quite happy how she is running right now.
The ignitech can do it to, use differend curves at different throttle openings.

The ignitech i use can switch between two curves using a switch on the handle bars.

Eeknows has allot of experience withe ignitech and zeeltronic, perhaps you can pm him if you want to know fore sure.

Cheers

[daveyoh]

cool thanks louis.

yeah the zeeltronic has the switch for changing between curves too. i think that the zeeltronic and ignitech are pretty much the same haha.
i just bought the zeeltronic one because i liked their website better haha

[daveyoh]

The curve you see is the max hp curve, i do not use the Tps sensor.

hi louis.

does the tps only take care of the VAJ system and different curves at different rpm?
is it connected to the powervalve system at all?

[EEKNOWS]

On the 20V the Solenoid Output will handle the duty on the air solenoids.Which means you can open the solenoid anywhere between 0-100% at any rpm you wish. I have posted up the standard Yamaha settings here which would be a good place to start.
With the Zeeltronic you can also make them TPS and RPM dependent.
You should see something like this

[louis]

Hello dave,

As far as I know the tps sensor is only in use to controll the airjest and ignition map selection.
The powervalves are controlled by rpm.

Witch and When the airjest are opened, deepens on rpm and throttle position.
Witch Ignitionmap is used deepens, where your throttle position is at that moment

Nice to know is:
3ma1 base advance is 19 degrees
3ma3 base advance is 21 degrees

But i don't have experience with zeeltronic, Eeknows has allot off experience with zeeltronic and ignitech.
He has post this air jet setup:


Hopes this helps

thanks for the replies guys

do you know much about the wiring of the zeeltronic eeknows?
on my bike im not going to be using the powervalves. theyre just going to be open all the time.

on the wiring diagram i got with my zeeltronic, it shows the tps and powervalves are connected by wiring.
if i dont wire in the powervalve servo, will that alter how the tps is working?

cheers

WTF? Why would you not wire the servo up?
I wired up heaps of them it is a snack. You only need connect 5 wires to the servo.

Here's a quick overview.
You have ignition advance
You have power valve position(expressed in % open)

The throttle position sensor (TPS) links both advance and pv, so the pv opening and advance can have different parameters depending on the amount of throttle. That is all the TPS links advance and PV(and lean angle if you go to GP)

[daveyoh]

WTF? Why would you not wire the servo up?

i've had some fiddling done on my engine, and it ended up being that if i wanted to run the powervalves they would need to be machined down quite a bit, which would result in them being a lot weaker and easier to break. decided it would be safer and easier (and cheaper!) to just have them wired open. shouldnt really be down that low in the revs anyway :p

so if i dont connect the tps to the powervalves, it will still function properly for the ignition advance and vaj system, but not at all for the powervalves - which wont be functioning anyway?

but having said that, warwick doesnt run the VAJ system, and i can just run one ignition curve like louis, so i dont really need the tps anyway?

[Warwick]

Without a working powervalve I would think that that will be one peaky beast . Even stock the exhaust timing is pretty wild for a road bike. I guess you can always retro-refit the PV's with the necessary mods later if you need to though so you can just try it and see how it feels first I suppose.

[EEKNOWS]

Well if  you don't need pv's I wonder why they sell very expensive kits to convert your h*nda RS 125 to pv? Wonder why EVERY GP250 made since about 1988 or so has power valves? Here's what I have found every HP/ftlb of power and torque created in the mid range is carried through to top end.
A 3ma has YPVS style spool valves how the bloody hell are they going to break? Why not just buy some new valves?

The ignition will do whatever you program it to do.
