Zeeltronic setup for a TZR125 4DL

[Louis]

Hi guys,

Trying to get some answers on a problem I have with the Zeel, Perhaps someone knows.

I connected the Zeel like it should, programmed a static angular of 80 degrees select tricker - and + on the pickup and programmed a flat 18 degrees line (till 10.000rpm)
She starts perfectly, and has a steady 18 degrees at idle (oem markings at idel are 18 degrees)
But ones you let the rpm rise and she is getting to its first set point (18 degrees from the set 18 degrees flat line)
She jumps somewhere on the flywheel, Witch is not right as it needs to be a steady 18 degrees

Have tried different setups, switch wires on the pickup but can't let it work as it should
(however I can let it work correct, but not on the way it should)

The 80 degrees should be right as I have found 80,5 when reading out the Oem CDI.
Borut helps me with this but it seems to be a problem.

So my question is, does someone has had the same problem with his TZR125 or DT125R?

Cheers
Louis

I've not had a chance to check mine yet Louis. I did order another one for my TDR250, and found one will work on both, and the later one will only work on the TDR but not 125. I wonder if that's the issue, he's changed the spec slightly and now it won't work with the 125 engine?

Hi Louis

I think it might be reading of the rear edge of the lobe low rpm and as you increase rpm it will read if the front edge of the lobe. I had that on my rz350 unit pdci10t or pcdi10t not sure but it is a 10t unit you need to set the unit to read a certain way its for after market flywheels.

Hello Martin,
That is good info, so you have a new unit that will run on a TDR250 but not on the TZR125 that is strange.

I have good contact with Borut, but he does not know what the problem is.
He tells me that he did not change anything at his unit.


Will try to investigate this further

Hello Edd,

That is absolutely correct what you tell, and till now the only way to get it firing correct.

I need to do the following.

1) Change the pickup wires (switch them)
2) program a 30 degrees static angular
3) turn my baseplate 10 degrees (max)
4) Program the pickup to use only the + pulse

Then she fires correctly

But you can imagine that that is not how it suppose to work.
Perhaps its something small I don't know.

Problem solved.....

After spending again a couple off hours measuring and trying different setup's
The solution was very simple, but not logical.

The problem was solved by setting 2 pulses per rev in stead off the logical 1 pulse per rev (as it is a single cylinder)

Now set on two pulses per rev the 18 degrees is spot on also on the high revs. (when a 18 degrees flat line is programmed)

Will inform Borut about this, hope it helps other Zeel users with there 125's

I wonder if it's to do with the long lug? glad you've sorted it eitherway Wish I had a spare few hours to double check mine!

Hi Louis

Interesting I would never have even thought of that.

Some info from Zeeltronic.

Hello Louis,
 Just tested what you did and you are right CDI has software bug.
 We made hardware and software upgrade in October 2017 and it looks like all PCDI-10VT are with that bug.
 I'm not sure why you are first who discovered that......

Solving the problem by setting it on two pulse per rev is not the solution.
It helps to get the ignition timing right, but your set rpm's are half what you programmed (That part I was forgotten)

Think Zeel will update his site with more info soon

just wondering how long before they offer you a job Louis 
seriousley excelent work Louis

[Martin77]

Maybe that explains why one of my pcdi10VT's works on both the TDR250 and TZR125 engines, whereas the newer one only works on the TDR... (purchased before and after the upgrade). I never bothered Borut with it as I just used them on which ever bike it worked on.

 I know that on the twin cylinder 350 PV & LC350 cheap skate Yamaha have been using a single coil 2 fire @ TDC & BDC ( ie 2 firing pulses per cylinder 4 pulses for 1 revolution of the crank ) So are Yamaha using this set up for single cylinder bikes? - If so it sounds like planned obsolescence i e firing @ TDC & BDC should make the coil burn out twice as fast !  Have Yamaha been bought out by Shimano who are bar stewards for planned obsolescence ""£$% !

[Martin77]

You've misunderstood Jim, on the parallel twins it fires twice per revolution... think about it...
