Dashlogic reading boost?
#2
Drifting
A zr1 map sensor, part number 12592525. Also tuner needs to know the conversion to use in the tune for proper function and boost reading.
And there's a formula and pid in the dashlogic that needs to be set as well IIRC.

Zr1 map sensor is one way. Any map sensor that can read boost. I use a DTE 2.5 bar sensor. Zr1 sensor is only plug and play for certain years so you may need a different one. If you don't want to mess with the tune then get any map sensor and just wire it to the dashlogic and setup the PID.

At this point, I think this needs to be a sticky
For an LS3 car the LS9/ZR1 MAP sensor is the way to go. It's plug & play. Just need to change the calibration values in your tune file.
For LS2 or LS7 cars, I don't think it's a direct fit. May need to modify the manifold and/or get a wiring adaptor.
Like Unreal said, you can also run a standalone MAP sensor and plug it directly into the DashLogic's 0-5 volt inputs. To me, that's more work and more complication, though. The LS9 MAP sensor is a much better solution.

DPE or DSX offer plug and play maps for ls7/ls2 if you wanted to do that.
If you don't have access to HP tuners or the tuner wants to charge to swap those values then the standalone is easy IMO. Not as easy and just plugging in a DSX or LS9 sensor but I rather spend 30 minutes wiring a map sensor to the dash logic than pay $100+ to have someone adjust the tune if that is what it took to get the other options working.

I'm not getting something here. If the car is boosted, wouldn't you already need at least a 2 bar map sensor to tune it properly? Then wouldn't the gauge read off that? I know my aero force gauge reads fine from the obd running the map sensor that came with the eforce.

I changed mine on both my C6 FI builds because 1) I wanted to be able to log boost, and 2) I wanted my effective injector flow rates to be accurate when in boost.
I don't think it makes a major difference to WOT fueling, but I like my stuff to be as accurate and consistent as possible.

No. Most boosted c6s are just using the maf. If it was a speed density tune then yes, you would need a map sensor that is accurate but if you are just using maf for boost then no need.

Agreed, I wouldn't do it otherwise and I've always had a map to read boost as I want it accurate but many just tune around it. Hell, most of the tunes I see don't even have the correct injector data in them, let alone worry about something like this. Just adjust the PE map until WOT is good and call it a day.
