😮не может быть! Вчера всё работало. 😂
Great video shows exactly how you can manipulate fueling 👍
If the Germans could make it more complicated they would.
Yay
Thanx for all good info here in south africa cant evan find seal for kjet system any places that ship internationally
Hi recently on my MK2 16v I noticed that the plug that was in the WUR was actually for the thermotime switch for the cold start system (2 pin brown plug). I’ve been trying to diagnose why my car has been running rich (failing mot on emssions too) could this possibly be why? Ignition timing done, new spark plugs, new injectors and a good clean of the intake system has already been completed 😎 I did find the wires that I believe are for the WUR so I’ve ordered a new 2 pin plug to give them a go.
It could well be yes if it's running too rich
@@GreyGooseRestorationsthank you!!
Does the car feel slower due to the sensor ? I’m having symptoms and getting code 000222 , can anyone help ?
Thanks awesome video doing my pump now...
Does this work on the motronic dpr as well?
Yes same part so works the same
@@GreyGooseRestorations thanks for sharing the knowledge of this system!
Yes
Do these also work on the 8V engine with K-Jet? any change needed for the hats? thanks for the video!
Yes, same principle applies if the engine has air shrouding, just block the air feed pipe
This is so GOOD !
Thanks for this!! I'm just finishing the rebuild of my 1.9l 16v PL engine with KE-jetronic. Wondering wether I should increase the fuel pressure or not. It has some mild cams, 4-2-1 header and the head is slightly ported. Would you increase the fuel flow in this case?
For KE units fuel pressure I fine in upper area of the factory settings, just a touch more fuel flow via the DPR and balancing is all that's needed
@@GreyGooseRestorations Thanks! So, 62ml in 30 seconds like you are showing here would be a good place to be?
@kristerantonsen yes 120cc/min is minimum required
Hi what was your symptoms? Did you have a check engine light? I have a 2008 mk5 gti EPS light comes on when engine is at full temp and randomly stalls? Thanks.
Do you soda blast the iron fuel distributors to clean the rust off the outside?
i bought a rebuild fuel distributor but when i installed it i notice there was little to no fuel flow to the injectors. when i press down on the plunger no increase of flow either. i did notice that if i unscrew one of the side plugs and leak gas out i get flow to all top ports and flow increases when i push down the plunger. would adjusting this screw help me with this problem?
Which car is it for? As pushing down won't flow fuel unless it's a Mercedes for example, the plate need to lift up
@@GreyGooseRestorations thanks for the response, and its a 84 190e Mercedes with the 2.3.
@Go_Jonn I wouldn't adjust that DPR screw until that issue is sorted, I'd check the system and differential pressures are correct.
@@GreyGooseRestorations alright cool, thanks
How did you get the throttle body out so you can uncrew the saitans bolt?
Im 99% sure I left it on
@GreyGooseRestorations how did you get to that difficult bolt on the manifold without removing the throttle body? I have been struggling with both for 6 hours.
Brilliant video thank you for taking the time to make it
No problems, it's helped a lot of people so thats a win for me
The vacuum chamber below wants manifold vacuum or ported vacuum ? The screw in the bottom will affect cold start control pressure and wot enrichment ?
The vacuum chamber needs manifold vacuum (after the throttle body) the allen key behind the brass cover will have an effect on all workings eg cold, warm both with and without vaccuum applied depending how well the wur is or how it's been set previously
@@GreyGooseRestorations Thank you for responding , I appreciate it . K jet is a brilliant system but it’s a bit a bit confusing I’ll admit . I’ve one more question if you’re up for it . You might laugh at this but I’m running a Mercedes 450 SLC with a rear mounted turbo . I’ve got great warm performance but if I shut it off for even five minutes it starts up chugging and blowing black smoke / stalling . I have an afr ratio sensor / guage installed which has been helpful . I’ve set up the warm mixture with the ( tap the steel cylinder into the wur housing ) method because I didn’t know any better . I’m wondering if my screw at the bottom is adjusted too far out possibly . Thank you for your time . I’ll have to send a few pics / vids of this beast I’ve created , you’ll no doubt get a kick out of it ..
@helmutswetglanz2590 oo that sounds cool, contact me via my Facebook page and i can help
@@GreyGooseRestorations what is your fb profile name ?
That's one sad PPR o-ring
Yea, not much left of it
Hello. Is there an initial setting for the air flap arm, as it changes with adjustment of the co mixture screw?… I assume, so therefore can affect where the main fuel pin will sit at rest? I’m having issues with idle co and pick up on 16v golf. Thanks
once the air plate is set correctly then the CO adjusts the height of the smaller arm but doesn't have any effect on the rest point of the air plate
@@GreyGooseRestorations thanks very much, my plate seems to be too high so I’m going to try adjusting
Any idea where I can get a filtering gauze
Which one in particular?
Have ever rebuild a CIS with a metal diaphragm? I have tried to do so for my 924 Porsche but failed. Any suggestions?
Yes, most of the ones I rebuild are the metal diaphragm types. They are the most common to be fair
Good job sir
My connecting air shaft between injector holes was completely blocked by carbon. Found out when replacing the head
Hi mr Goose, i have a Ke jetronic on my audi 80 and it keeps searching for its revs at idles by about 400rpm up and down. Have vacuum tested and all good so mechanic thinks fueling. Any ideas? Thanks
Hi, You're doing a great job on your channel! Could you describe the issues with the KE-Jetronic system? I'm having a problem with the engine running unevenly at idle.
I made a rookie mistake and made both the adjustment you describe and the adjustable pin method. Is there a base setting on your modification that I should target on my WUR?
Unfortunately, it's hard to have a base setting as there are too many variables with where the fuel cell sits, the heating element pin site and the spring rates on both the springs and how well the vacuum diaphragms are working
I still have a KR engine in my garage, thinking about putting a little turbo on it, just to see how that performs with a stock Kjetronic 😂(maybe with stronger conrods and a thicker headgasket) i have no idea hoe it will turn out but I am looking forward to it 😂
Yeah it should be fun 😁
Not sure what your source is that states the filters were added to protect the debris during the assembly of the engine? My experience with German manufacturers is they had a very high quality and they were not be concerned about debris in their factories. Their concern was rather contamination in the gasoline and during engine maintenance. Unless you have Bosch documentation that states removal of these filters is OK, then you a doing a disservice to your viewers.
It stated in the vw service schedules that dealers had in the late 80s early 90s, out of say 10 units I only find one or two that still have these fitted albeit heavily clogged.
Where can I obtain the Warm up regulator bolt that has the filter?
Hi, contact me via my Facebook page and I can make one and take payment
Not sure why in all my research into K-Jet I've never stumbled across your content. It is excellent, really informative and helps to validate all the reading I've done. I've rebuilt the metering head and WUR (16v variety) on my Mk1, and got it running pretty well. When you are doing your volume tests, are you running your rig with a 'warm' WUR, and what position do you have the air metering plate? Haynes manual for the Mk1 doesn't give per injector volume figures, just says to run until you get 100ml and the others should be within a certain % tolerance. Do you know if there are specified per minute volumes published for the Mk1? Sorry, few questions in there! Keep up the great work.
Hi, I use a power supply to simulate a warm environment. Minimum fuel is 120cc/min per injector with the plate lifted 25mm from rest and 20cc/min with the plate at 2mm lift Ideally you want zero imbalance across the number of injectors
@@GreyGooseRestorations brilliant, thanks for the reply, time for some tinkering I think!
Audio sounds like a horror game XD. On a side note please look after your pulmonary systems yall, it takes too many hard workers too soon.
Hi would the shim modification work on a mk1 golf gti ? And do you need fuel pressure gauge, (havent got one to see p.s I) and how many shims would you recommend without using fuel gauge ,is it best to a pressure gauge? And also would the W.U.R modification work looks slighty different , awesome videos thanks for any help 👍
You ideally need a set of pressure guages to see whats its going first before upping the pressure. The WUR modification in principle is the same with lowering the control pressure
Ok thanks for your help😃 👍
I think the car will be amazing. Your mechanical knowledge is almost unbelievable, you will make it work and can't wait to see the results!! My mk2 still in paint hopefully not to much longer🤙
Thanks 👍 hopefully yours will be ready soon, paint is the hardest part
Some times increasing spark , like putting in colder plugs or boosting up the coil to get a bigger cold burn can increase cylinder head temperature as the fuel entering the head does help cool it , So be careful when not sticking to manufacturer specs
Nice! Great work. Where can I buy one of those rain trays? Thanks
If you contact dubstock he can supply good used ones, get the hard plastic type like the one i have
I have the same fault on my mk5 golf 2.0 FSI is it located in the same place? Thanks
Most likely in the same area
Meaning the use of both 276 and 288 will work perfectly well ??
288 is getting way to high for Kjet to work as the overlap casues air to back up in turn pushing the air plate down which will lead to poor running and starting
So happy I found your channel. I've had a 1.6td out of a mk2 jetta in my rabbit pickup (caddy to you guys) for the last 6 years and it burnt a valve but I'm in the process of swapping in another one and I'm stoked to have these videos so i can properly tune the fuel now. Cheers from Washington State!
Ace, hopefully it helps
This is going to be such a cool car, can’t wait to see it done and on the road
Thanks 👍
that engine won’t work very well in the mk2 i think if you put it in my mk1 cabrio it will lol great build mate
😅 thanks
Hi mate, any chance you could explain setting up the distributor for a first time start up? Ive got no set points or markings on my distributor and struggling to get a position to fire the engine up.
With the engine at TDC the distributor should fit with the connector on the bottom then the rotor arm should line up with the notch thats on the distributor housing
@@GreyGooseRestorationsI have finally got it running but think the timing is out, doesnt seem to rev past 2-3k and the spark plugs are black after a few minutes of running. My gearbox inspection plug is stuck so thats my next job!
Hola, le escribo desde España. Enhorabuena por su canal, en estos días es dificil encontrar mecanicos entendidos en esta inyección K-jetronic y los mecánicos aficionados nos encontramos con grandes problemas para mantener vivos nuestros coches clásicos. Le expongo mi problema, soy propietario de un Mercedes W123 230E de 1982 y últimamente está dando problemas para arrancar en caliente después de haberlo dejado parado durante 45/60 minutos, arranca pero no mantiene el ralentí y se para. Hace poco lo cambié la bomba de gasolina, acumulador de presión, filtro de gasolina, inyectores, válvula de aire adicional y todos los tubos de caucho y el coche funcionaba perfectamente, pero hace un par de días empezó con este problema de arranque en caliente, aunque después de dar arranque varias veces y mantener el acelerador pisado a fondo al cabo de un par de minutos se estabiliza el ralentí y de nuevo funciona como si nada pasase. Usted me podría indicar alguna posible causa de este fallo ó como buscar el diagnóstico? Le estaría inmensamente agradecido, y le repito la enhorabuena. Saludos desde España. Fernando Alonso.
Hey can i make this whole setup on a 70HP JR engine too? How strong can it be?
I bought the k-jetronic manual at emanualsonline - survey asked why I chose them - because Grey Goose told me to! :)
Thank you for the video, can you please give me the part number for the Mercedes fuel injector?
Bosch number is 0437502047
Hello, one question: which manufacturer did you get the sensor from to install it in your car?
Genuine Bosch part from TPS
Nice sound!!!!🔥
Its addictive
