Hi Richard

I have wired up the map switching and did a test to confirm the ECU is switching maps - everything is checking out ok.

I am going to start tuning for WI tomorrow, with the failsafe signal triggering a compensation table for fueling as well as ignition, with a separate 5th injector 'fueling' map to control the HFS-6.

How will the PWM input work? I currently have it wired up as a 5th injector and fed that into the IDC wire on the HFS-6. Based on my understanding, the HFS-6 trigger point is 42% and gradually increases, as per the graph on the manual. Or is there an alternative means of control ala System 2C/D?

Wish me luck!

Cheers
Dennis

PS Photos of the install and tune to come shortly , if everything holds together...

As for the water injection table, I'm intending to tune it directly as an injector, much like the older 2D(?) system with the HSV. The default IDC trigger is 42%, can I set this down to 0 so I work it directly? Or is there a base IDC I must have before the WI will trigger?

Thanks!
