D-Jetronic Porsche 914 2.0L ECU, Bosch 0280000052

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.

Everything is possible. I am sure the guy who sells such sport cam shafts can exactly tell you how to tune the ECU and is not a simple Sell and Forget guy. In 912 you should re-tune carburettor with nozzles, in D-Jetronic you change some resistors. No problem for him. Just ask for the tuning manual.

Hello

there, I have a big doubt !!

it's at Oratech

I will dismantle the engine in early November and return the original ACC

Hi Lux Pierre,

max. Cam you can run with D-Jet is 262° WebCam with max. CR of 8.8:1 but not easy to adopt the D-Jet.
276° Schleicher would work much better.
If you don't want to spend a year or more to tweak your system, convert it back to stock!

Porsche 912 is L-Jetronic and the AFM can handle a slightly different cam better.

Best Regards,
Frank
