Turteller og AFN

[ssrt]

Er det mulig å finne & koble signal fra t.d. en AFN til orginal turteller?

bruk w signalet på turtelleren... har du ikke så bytter du til en som har....

Ja, det er mulig. Her er oppskriften:

Hi,

I converted my T3 syncro (vanagon) to TDI (AFN code engine).
I tried to use the tacho output of the TDI ecu (pin 2/68), but factory tachometer of the T3 (gas engine) did not work.

I took the tacho out and examined, yes there are resistors (a voltage divider) on input signal.
The chip used in the tacho is SAK215, it is a frequency to current converter. I found the data sheet of SAK215 (googled it) and it says anything between -20 to +20 V is valid as an input signal.
As the TDI output signal is a 0-12V square wave, I just directly conected it to input pin of SAK215 (bypassing all the filters and resistors in tacho), and it worked.
It is accurate as expected!
