Well the issue is that the Ignitech is as confused as you are.
The Honda function cant work at all without a TPS as that is like a woman going to work without shoes.
Read the truth table its based on.
Initially we have RPM below 9500 and TPS below 75% - in this case nothing happens ie fuel flows no matter what.
In the second column we have a tick in the box giving anything below 9500 and 75% TPS initiates power to the solenoid ie no fuel
Also in this column is the second, lower box with no tick. So - above 9500 and above 75% there is no power to the solenoid ie fuel flows.
Moving to the 3rd column - top box is a tick as well as the lower box.Thus no matter what TPS, above 12500 the solenoid is activated ie no fuel.
What is there to not get - apart from the fact not wearing cool new shoes is a criminal act.

I'm fucked.
Lock me up.

All of a sudden I have lost my train of thought.


Re the Gear encoder Honda and Aprilia used a different setting for each gear to allow for the cooling effect of the airflow at higher speed? is that right?
I think i can remember Frits or Jan saying they eventually went to GPS or was that only re the ignitio curves or both.
i remember posting a suzuki GN gear encoder a long long while back

No doubt the 122/123 is a tricky engine to get some dcent HP out of. The standard pipe wors well if you do 2 things 1) cut 30-35mm from the belly 2) roll or machine a insert to take the stinger dia down to 23mm. That gives a peak close to 12,000 they do not like any more than 8deg after peak otherwise it kills the over rev. If you really want to have fun install a 115mm rod.

Thanks.

Peak close to 12000? I am really making a pike for a stock, 28 carb Aprilia :/..... my ideia is get the peak at about 10000 / 10300 so would rev well to 11500 as the stock ignition seems to not let the bike go further. But for these RPM's I would think about 960/950 tot lenght, or the aprilia gases are cold, or the stock stinguer is very big and does not alow the pipe to heat much inside.

Is there someone here who have any good clue that can post?

This is really a stock or little tuned aprilia pipe.

Thanks

My understanding of the gear encoder was that it related simply to the acceleration rate in the lower gears.
The engine can withstand a heap more advance whilst spinning up real fast, but in 4th 5th 6th the rate slows due to aero and
deto sets in with too much advance wound in.
The cooling effect may have some relevance but not as marked as the accel rate I believe.

Still dont understand why anyone would wear shoes like that whilst in bed.
But then I dont even wear them at all, not having any feet on the ground.

Ahh, so the lower row is Above 75% & the upper row is Below 75%?

That is confusing. But now I look at the 2D map with TPS ticked it is consistent.


Actually I'd assumed that because the TPS wasn't ticked it was greyed out.

So I need to get the TPS fitted before I continue seems to be the answer. Silly me.

However
Currently the PJ flows whenever it feels like it. if I created a special chart like below.

1. Below 1200rpm solenoid off for easy starting. But then turns on closing PJ
2. Starts flowing after say 8000.
3. Turns off just after peak for some of those Pennies from Heaven I'm chasing.

Will this make sense until I have a TPS sorted out?

[wobbly]

No sense at all.
If you want to fool the ECU into following the truth table without a TPS fitted then feed the 5V ref out directly back into the TPS pin.
Then the ECU will think you have full throttle all the time.
Set the TPS to max mV at 100%.
Set the table to have TPS at 101 and 102 and it will do what you want thinking you ride like Lorenzo.

[F5 Dave]

Ahh, I've just been reading up on TPS setup, thanks that makes sense. Thanks.
I have a TPS but have to sort out a reliable setup with space avail (no chance of fitting an RS/RGV one + people want a zillion for them these days).

So the Ignitech will think I'm cool? Awesome.

Cable splitter and a remote wheel with the TPS is the easiest way, shirley?

[F5 Dave]

Have all the bits and bearings to remote it under seat. Just need to machine and assemble and make a lever arrangement and spring.

[Grumph]

Didn't I read somewhere that when people using customer RS250's needed a tps they ran a 3rd carb with one fitted....tucked the carb away somewhere out of the way. Quick and dirty but would work.

[F5 Dave]

I'm not made of money for flash carbs esp not spare ones.i have the $30 tps, just been lots of other things to be done. Which is why I should stop tapping here and head down to garage

[husaberg]

I'll bite what is the 30 dollar TPS.is it off a car?
I had a look in my carb box i guess the NSR was a remote one or mine are off a 21 rather than a 28 or what ever.

OH edit Later it was like a car set up off the spindle


I actually had a quick look at the PWK not sure how it works.....

must google exploded diagrams.

oh look at this KTM ran the PWK shorty with solenoid PJ but with a greater downdraft

but still the SX is twice as much as the YZ.re KTM It may be hard to see in this picture but it measured right around 28* on the SX.

Pretty sure Wob mentioned something about mods to the pick up as well as the PJ inlet earlier?

[F5 Dave]

Interesting about SX carb. Either way tps is where shock on NF4.
