PFC and 3bar MAP sensor
Hi,
I have a PFC with a base map currently. I have my car booked in to have some 1000cc primary and 1600cc secondaries (along with other fuel upgrades) and also to install a GM 3bar MAP sensor.
Now, my tuner is saying that my base map will not need to be changed for these mods, but I was under the impression that the 3bar MAP sensor will "shift" my maps. Am I talking bollocks?
Thanks
Martin

you gotta install it right and change the settings for it to read right or you'll blow up your engine fast!

B // MAP SENSOR VOLTS // Greeen/Yellow
C // 5V // Brown/White

well I installed a new 3 bar map sensor.... if you weren't to change the settings using dataloggit, would it cause the car to idle all over the place...run for alittle while then completely shut off?
I don't even know if my dataloggit is working, the light comes on and i plug it to my laptop so I can change the PIM settings, but it wont read the current map that's in the car, plus if i change the settings, hit update and and what not, everything is still the same...is there any specific way to make sure your dataloggit is working, or any specific order you need to do things to get it to work?

What happens to the P side of the map when we install the 3bar map?
Do we need to rescale it? If i put the 6270 and 0 on option to and click option 2 without changing the Map reference would the car still run same as before?
Thanks

The 41800 number is for the old Datalogit software that was specific to the FD. Divide that number by 6.66 and you will get the value for the current Universal FC-Edit software. So instead of 41800 you would use 6276. There are a couple different values floating around that people are using for the GM sensor.
