Welcome to the forum. KE jetronic is slighty better on fuel but the difference is not noticeable, I'd stick with what you have.

Is it a 4 cyl, or a 2.6?

Quite a bit more electronics on the KE = more things to go wrong! Main air/fuel metering unit is exactly the same. Its the warm up, fast idle and fine mixture control/lambda sensor bits that are different. You don't get a marked increase in efficiency till you move to the electronically controlled individual injection and integrated [distributor-less] ignition systems of the later models = even more things to go wrong! Welcome to the forum.

Many thanks for your quick responce, the engine is 230 8v

ok.. so it seems that i wont feel the difference ?

Mr grober ! you said individual injection,,, is it applicable ??
because i saw many systems on the internet but i know that i will have a mapping problem ! right ?

 

[grober]

Its a major operation to change the injection system from standard. Aftermarket systems can be bought but as you said they need to be set up [ mapped ]on an engine dynamometer and are frequently designed for competition use to extract more power from an engine rather than help idling economy and general smooth throttle response over a wide range of engine speeds. Carat 3.6 amg's advice is good and he tunes these engines! The Bosch K/KE jetronic are really quite efficient and very reliable if looked after and clean fuel is used.
