HFS2 kit photo of HFS3 board (black). serial number is 100981


Yes mazda uses skyactiv engines with direct injection in mx-5 from 2015, (longer in other models, I think from 2012/2013 mazda 3/6...) :

I will try to connect hfs2 to skyactiv ecu. I was afraid of damage the mx-5 ecu with hfs3 circuit board with not correct "A" and "B" section adjusted for DI.

So I will try to connect green "USER" harness red cable to skyactiv ecu 1st injector output position 1DP(red) and green cable to position 1DO(white).
"A" section CUST solder link, PWM cut link
"B" section x2.5 solder link, x1.0 cut link, am I right?

I really need the serial number of the controller, it is on the button left of the circuit board.

Without it, I cannot identify at the stage of the Di development we were at. It is not easy to help you.
