Porsche 993 aircooled engine in a 914
Posted: Mon Sep 21, 2015 8:45 am
Hello forum,
this is my first project with a free programmable ecu!
I have a Porsche 914 with a 3.2ltr engine for more than 20 years.
Now the 3.6 twin spark 993 engine should go in.
The project is mainly based on the stock parts, as there is:
- 60-2 trigger on crankshaft stock
- TPS Bosch stock
- IAT stock
- CLT ... there is no c
But there is a zylinderhead temp sensor. May i use that instead? But temp may be more than 120deg (max to choose in software).
- 3 wire PWM idle valve stock
- 2 knock sensors for 3zyl left and 3zyl right stock
- MAP sensor in EMU integrated
- 2 x 6 Zyl block Opel Ignition coils
- oxygen sensor LSU 4.2
I will not use the air mass sensor and the hall sensor of ignition distributor, what gives the cam position.
Just leave away the distributor.
I think, there is no need to sequential ignition and fueling, is it right?
Is there something forgotten??
Best regards,
Olli
