Default EJ205 Cam and Crank Pulleys

Hi all,

I'm currently setting up a Link G4X on a Version 8 WRX with an EJ257 (instead of the factory fitted EJ205). I'm unable to start the car and I suspect that I have the cam and crank triggers setup incorrectly in the ECU. I was wondering if anyone has any details of both the cam and crank pulleys in terms of the number of pulses I should expect to receive per engine revolution. Any information regarding the voltage pulses I should expect to see from the respective sensors (I think they are hall effect reluctor sensors) would be very helpful also.

I have run the EJ257 on the (reflashed) standard ECU so I'm confident that the triggering system is the same as that of the EJ205.

Please feel free to let me know if you have any questions.

Cheers,

VFR22B
