low impedance injector characteristics screen

Hello

I am trying to configurate my low impedance injectors in Tuner Studio, but I dont find the way to introduce PWM current limit, PWM time treshold and injector PWM period values, my screen gets these values in gray and I dont find the way to activate them.

Am I doing something wrong? Thanks in advance

Microsquirts can't do PWM current limiting. You can drive 1 Lo-Z injector per driver, or up to 4 Hi-Z injectors per driver. Take a look at the Introduction to the V3 MicroSquirt® EFI controller; scroll down to point #4.

If you need to control more than 2 Lo-Z injectors, you'll need something like jbperf's Peak and Hold Board.

Ooopsss.... sorry for the mistake :oops:

I was using the "Tuning Software for MS-IIâ„¢ v3.7" page for my config and forgot Microsquirt specific guide

Really sorry, thanks for your help
