Hi,
just noticed this...
Does this mean your engine isn't in original condition, was tuned to 'nominal' 130 hp?

Is the camshaft you posted in the last posting installed?

A D-Jetronic system is 'composed' to run a specific engine with specific parts. The D-Jetronic-system isn't able to detect changes in the engine setup and can't run a modified engine.
You will have to 'compose' a new setup for your modified engine.

Exactly,

a modified engine means that your original components do not fit any more. D-Jetronic is an open loop control, not closed loop. Inside ECU there are various function blocks that are adapted to your original engine. One of them is filling curve of your engine. That reflects how much air is really suched into engine at which revs. It is never really 2.0 l, always less. It depends on air flow resistance in manifold and valves etc. You have changed this definitely with a sports cam. how yould the ECU know that?

yes the camshaft is installed.

I had heard that on the 912 E
he could pull out 135 hp

here i have 9.21:1 de RV
and the new came chaft

Then he can surely also tell you how to tune your ECU appropriately

hello volker.

you think it was possible to adjust the ECU ?

if not me I disassemble the engine and I put the original acc. I have a new one in a box.
