Title: Logging MAP sensor raw voltage output Post by: Scrampa on May 14, 2022, 11:27:51 AM Hello all.
I have a water/meth setup I'm going to be installing on my '01 S4. It uses MAP, MAF, or Injector duty cycle for activation of the WMI pump. I will be tapping into the MAP signal wire to feed into the Water/Meth controller, but first want to log output voltage of the MAP sensor during a few pulls so the controller can be better calibrated for activation and flow rate. Using the M box file. Is there an address that can be logged for this? I can't seem to find anything directly relating in my me7logger ecu file. It has crossed my mind to adjust the factor of pvdks_w, but am unsure of where to start to determine the proper value if it's a viable option. Maybe a nudge in the right direction would help.

If in ME7 for some reason load actual be bigger than spec. It will close TB and MAP will read very high boost, wmi pump will work but at TB 30% that is really bad Title: Re: Logging MAP sensor raw voltage output Post by: Scrampa on May 15, 2022, 06:13:43 AM Don't put wmi on MAP signal If in ME7 for some reason load actual be bigger than spec.

BlackT - is that due to the MAP being pre TB (a MAP reading manifold source would be OK)?

Put secomd MAP in manifold or use MAF signal Title: Re: Logging MAP sensor raw voltage output Post by: Scrampa on May 15, 2022, 06:07:59 PM Yes Put secomd MAP in manifold or use MAF signal Great.
