Angry Why cant i change PWM values in tunerstudio?

hi all,

iv just put in my 440cc injectors, they are low impedence injectors and i have the board modded for them.

I came to change the valuves of the PMW like the threashhold etc and for some reson on tunerstudio they are grayed out and i can find no way at all of changing them.

Can anyone advise?

ms version? software?

i grabbed jbperf's peak and hold driver for low resistance injectors because ms1 with hires code can't do PWM.

I installed Vipers MSII for him. I think it's a bug as it does the same thing on my car. All the PWM stuff is greyed out.

I've posted on MSExtra about it, I think it might be a bug....

With dropping resistors you effectively have high impedance injectors, so yeah don't worry

You don't mention your firmware version, but I'm assuming it's one of the MS1 HR's. HR does not support peak and hold. The work around is adding resistors, as you've already done.

looks like MS-II so it's shouldn't do that, probably a random setting or a firmware glitch. What firmware?

Jean of JBPerf fame figured it out.

Despite running batch injection he has 'additional drivers' selected under the sequential options tab.

Still runs as normal, (so you can return to batch/semi-sequential in software - find dead times etc ), but with sequential you can't use peak and hold injectors, so the option is greyed out.
