A stand alone is a programable aftermarket management system.
Ie;Haltech,Hestec,GEMS,VEMS,Speed Pro asf.
..and before you shrug away from it...trust me when i say that install is MUCH easier than most would think.
As far as pollution legislation in deutschland tho...i for one would check that first.
But if it´s ok to perform such a modification..just do it.
The difference in behaviour as well a power isn´t on the same map as what can be had of the KE-jetronic.
To give you an idea..
I was around when the K systems were all we had to work with-back in the 80s.
Around here..laws permit us to modify cars a little more than the average european country,and...yeah well..i just happend to have an old Porsche 931 around that i used as daily transport.
Prob was..it was a damn slug...i mean..it couldnt move out of its own way.
So..
Hoisted the engine out of there and rebuilt it.
Used commonly available CHEAP forged Mahles for the VW type 1 engine.
Swaped the stock turbo for a K27 series instead and remade the entire intake system.
Because i´m a hardhead..i insisted on keeping the K-jet unit that was already on the car to show the younger generation that it CAN be done with a simple piggy back ad on fueler for the extra fuel needed due to the rather large turbo of choice.
Yep.
Did work.
After a LOT of headaches and a LOT of hard work.
None the less...we calculated that the K-jet housing by itself cost us around 50 horsepower at full bost(2 bars)
Just to give you an idea.
Now..i know how the K as well as the KE-unit is built.
From scratch up.
I know how to modify them for performance,and i´m here to tell you...
It simply isn´t cost effective.
Don´t get me wrong..
For the "small" mod guy...it´ll perform perfectly well,but when you want to increase power by for instance 30 hp or so...it just isn´t worth the hazzle to dive into it to make it perform these days.
Take a look at the VEMS unit for instance.
It´ll even within reason program itself...
