Ive got the AFM/MAF equipped 8v Gti which I think is the Digi - I take it this is the more modern setup of the 2? Mine is a E Reg Gti?
-
Sounds like you've got the Digifant equipped car.
There's no contest - the K-Jet is a simple (read stupid) mechanical system, whereas the Digifant is proper EFi, lacking only a lambda feedback loop to be 'proper'.
-
Digifant is the better system.

mines got lambda feedback :tongue: :tongue:

Mines got lambda feedback too - my nose and the overpowering smell of running rich :cry:
-
new lambda probe :wink: :wink:
did that one last month :angry:
just as a foot note , Kjet isn't EFi it is a silly injection system that works on fuel pressure to open the injectors
full of problems and "my" opinion is it is crud !!!!
digi is much better (when it is set right)

K-Jet is still a good system and only really has problems if dirt gets into it.

So has mine, but I can't get it to work dammit. So the ECU is constantly in 'get ya home' mode. Very expensive to run like this.

I like my k-jet system because its simple. I don't think you should write off an injection system as "rubbish" just because its old fashioned. This is a bit of a silly example, but its like saying a Ford Focus Zetec engine is MUCH better than a 1960's Ford Mustang V8. What I mean is, newer technology will always be better than old, but that doesn't have any reflection on the original.
I'll probably at some point go down the ABF route, but I won't look back at my K-Jet days and say "what a sh!t engine!". The 16v KR engine came from a really interesting point in motoring history where engines became fuel injected, getting rid of carbs/chokes and all that hassle, but were just before the point of everything going ECU crazy. Its a cracking engine peeps!
Oh and PS... When you 8v digi boys are overtaken by a 16v running K-Jet, you can console yourself that your injection system is far superior. LOL!

Uless the 8V digi is running a G thingy blower! :tongue:

i have a 8v kjet better that that other sh*t, i think,well thats just me a i think its faster

8v K-Jets are fast. Partly due to their revvy setup, but also because they tend to weigh less than most Mk2's as they were pre big bumper, pre electric windows etc. etc.

K-Jet ran right on into big bumper models, so the above isn't quite true.

8v K-Jet??? There was 8v K-Jets from the factory post 1989, with big bumpers? In the UK?
I don't dout you, but I'll be shocked if thats true.

Not sure if that is right, I remember Digi coming in around the 87/88 with small bumpers, I have never seen a big bumper K-jet, big bumper models were launched in 1990.

8v k-jet stopped in 87, 16v k-jet carried on right till end of mk2 production.

I often compare apples and bananas and am surprised at how different they are.

We're talking about the injection system here, not the motor. The KR motor is a very good motor, but is runs a painfully simple injection system. With the variety of injection systems available today it's possible to get more power out of a KR motor with a different method of injection. Installing the ABF Digifant 3.2 system on a KR might create some interesting results.
Yes there were Digifant systems available with lambda in Golf2s but only on the continent on catalytic converter equipped cars..... I'm running such a system on the Syncro at the moment. I was due to nail an ABF in to the car soon, but as I have a Megasquirt system lying around I'm tempted to replace the Digifant II system with Megasquirt on the 8V I'm running with at the moment - it'll be interesting to see what difference we can pull out of the motor just by changing the injection system. Might prove a point or two, or disprove some things which would be just as interesting.

toyotec did some experimentation on his, though it was a 2.0 8v. the results were very good and well documented on clubgti :)

Linky?

motec FTW :)

motec FTW :)
ssssssoooooooo expensave !!!
but it is fooooooking good , we use it on our sidecar , but the ECU is the dash and when i rolled the outfit , it got smashed :cry:
try webcon , their stuff is great quality

Hehe... I did say it was a silly example, but you know what I meant. :smiley:
