Are there any one more then me out there running that setup?

You have any problems with jerking between 1000-2300rpm?

Have you problems with nailing? The 8mil elements nailed horribly in part load. I've got a soluton about this... What about nailing on the 7.5mm elements?
Yes, minimized it by adding a additional spring to the rack. Only have jerking in part-load condition. The coil has too lees spring tension at low IQs. Also using the new pump map helped to get rid of the jerking issue. There are still some oscillations left. First I will try to add a harder spring. If this will work I will set the brackets towards more fuel = more tension on same IQ.

I had nailing at midd rpm with 8mm mechpump and WOT. Not with 7,5mm mechpump and not with 7,5mm EDC. Use same drivegear with alittle more advance in higher rpm (grinded stopps) on all pumps.
Okay, so you are the guy that Baldur refers to. So i might need to send my pump to Dieselmeken again to put the spring in after i find one? I opened another EDC and i had to remove the rack to get the spring out.

EDIT: With 6mm pump i had no problems with jerking/oscillations. It seems that with 7,5/8mm the rack spring on low load is to weak and element is to effective.

Otherwise from the oscillations its a great pice of ECU.

I have not touched the engine/transmission.
I changed the rear flex disc to a bigger one, a stronger prop, longer ratio 210mm diff, poly bushed diff to subframe mounts, uprated trans mount different wheels and tyres. Something I did there eliminated the jerk, (it’s not reduced its eliminated) and the car is now infinitely nicer to drive.

Ohh ok. Never had that problem with 4 different pump. But this EDC one have oscillation on low racktravel. You can feel it and see it in the computer.

Adding tension to the rack spring and diminushing the tq control control help a lot... but in some pumps does not solve the matter at all.
I have a pretty much idea of why it does in mech pumps but the idea need to be tested and it takes time....

The problem is in part caused by the orientation of the rack inducing a feedback between vehicle acceleration and rack position. The rack is mounted longitudally and so sudden acceleration of the car pushes the rack back a bit reducing fuelling, and sudden deceleration pushes the rack forward. I noticed this when I had a mech pump in my car, if I was in neutral gear and braking hard the engine would hang at high RPM until I was done braking, then it would fall back to idle.

i was not talking about that ... its nothing related to that ... jerking people complain and i too have is part load driving and not cause of what u refer above, wich i do not refute.
Looks like people complain of dsl1 powered pumps too, and why is the driver induced oscilations... well i have no answear to that ...
For the mech pumps i have , and when i have complete control over it i'll post my conclusions , and solutions.
For the moment i can recomend to increase rack spring tension to 2 as much , and for those u can and know how to do it reduce tq control cut out to min.
I do hope toguether we can fight this problem with success.

The same mechanism also plays in the jerking. When the car accelerates and decelerates repeatively those motions feed into the rack.

Adding a additional spring to make the rack-tension higher did major success. I will add a harder one and see what happens...
Even with the pedal floored (no oscillation in the drivers wish) the engine is oscillating. In my opinion the rack can't get into home-position that fast it should. The coil wants to move the rack towards less fuel, but it gets stuck a little bit. After a little time the rack is moves towards less fuel, too and goes below the target point. The PID-loop governs the rack and coil towards the targetpoint and overshoots a little bit. Now the PID-loop gives less pw and the coil has less tension. And everything starts from new...

(09-02-2017, 08:12 AM)firen456 Have you measured your spring? I didn't have time so far to make a picture... I'm very busy this weekend
No and it was difficult to install. Im going to call meken on monday to discuss a heavier main spring and maybe send the pump to him again to install one over the winter.
Was on the track whole day today and the car have great power all up to 6600rpm were my limit is at the moment. The setup i have this summer with this EDC pump is the best so far. For the first time im very satisfied with the register and power.

So... Did just get off the phone with Göran "Dieselmeken". I will send him my pump and spring ive made and he will do some investigation and tests. We think we have a solution about the oscillation.

I wonder what causes this issue... Maybe he will find out what's going on there. The EDC-pumps seem to be weird in some cases... Where a 8mil element is running fine in a mech pump, the same element is nailing like hell in a EDC-pump for example. I'm interested if this oscillation-issue can be caused in a pump-bench, too... Whithout the engine running, there is no oscillation, only with the engine running it appears. And only at a certain enginespeed. The same thing about the nailing of the 8mil pump. But there is a solution to minimize it.

(09-04-2017, 07:50 AM)firen456 Ok, wonderful
One thing i think is doing it is the timing advance. More advance less rack and fuel. If timing is changed to quick then the pump tries to compensate and then it starts. Thats why every thing is okay when engine is off and no load to engine.
The original spring is to weak at a racktravel of 800-1100 in Baldur ECU and i guess that the solenoid have problem to compensate and start to oscillate. A harder spring seems to compensate this according to both yours and my live tests.
I did put in a harder spring and i have almost no oscillation now compare to before the spring.
About the nailing for you, try to retard the timing?

Done some more investigation and talk with Dieselmeken. We might be on a easy solution with racktravel and idle settings with Baldur ECU. So its possible in the future to get same racktravel (21mm) with EDC pump as with Mech pump thanks to the tip of firen456.

I have a spare EDC pump here on my second 606, which I would like to send to Goran for an upgrade, but it's a completely pointless exercise for me to do so if there is no proven solution available.
My other pump is mech603, and reconditioned to new locally but tuned with .964 elements - it is obviously quite good for it's intended function. Stock 606 turbo, so no need to go bezerk on it.
The spare engine I want to go DSL1 for my own reasons. If 7+mm elements cause the oscillation then I'll need some documented facts to support doing it.
When you have resolved the issue, please let us know.

11-02-2017, 04:27 PM #36Thought this could be useful for this thread. DieselpumpUK anti jerk setup. Could be worthwhile trying on the EDC pumps with larger elements.

That is for mechanical pumps only?

The kit has completely illuminated the jerk/bonanza. For £300 the kit is an absolute steal, the jerk thing can completely ruin any STD project.
(PS – for some reason 5 cyl cars/pumps are not prone to jerking – dunno why but that’s just how it is.)

11-22-2017, 08:42 AM #41OK – I have just been on the phone to DPUK and they have fitted an Anti Jerk kit to a costumer’s car that had it so bad it would even do it on the rolling road.

The DPUK solution is very similar and quite genius.
On old diesel engines that would jerk(rpms go up and down mostly at idle and low rpm) we used 90 weight gear oil instead of regular motor oil in the pump governor. The thick oil would dampen worn out governors and stop the hunting effect. Of course this is impossible in engines that use pumps lubricated from the engine oil circuit.

My 5 cylinder jerks (jerked...) quite a bit. Maybe it was due to the gearing setup (3.46 diff)

That's superb info, I suspected this would be the case - some cars with the jerk get worse as the engine heats up an I was thinking about somehow sealing the pump and running it in thicker oil.

Mine still hunts at idle - I'm looking fwd to see what difference the kit will make in this regard.
