100% MPS - How to Set Threshold & Gain
 

I have a modified 997.1 Turbo. I’ve been successfully injecting based on 100% IDC. I’m getting some tuning revisions and would like to switch to injecting by 100% MPS. After I do the soldering, are the THRES and GAIN pots the appropriate trimmers to shape the flow by voltage (boost)? If so,

THRES – Do the 7:00 (full left) and 5:00 (full right) settings correspond with 0V and 5V or 0.5V and 4.5V (as I understand that’s typical for MAP sensors)?

GAIN – Does this modify the slope (after threshold) of the slope provided by (0.5V @ 0% flow) & (4.5V @ 100% flow)? If so, is 11:00 (one left of center) +40% slope and 1:00 (one right of center) -5% slope.

If threshold is set at 2.5V, then 0% flow will start from here?

Thanks,

Steve

If THRES is set to 2.5V, the system will start from 25% idc. No flow at 0%
