Scaling 3bar map reference

[xracerx972]

So with the stock PFC map reference for an Apexi 3bar sensor, Im pretty much maxing out my load reference. If anyone else is running high boost on a 3 bar, whats your reference table look like? I could use some ideas for a starting point on rescaling so Im not hitting the p20 cells... Stock, the PIM is 20000 for the 20 row. I just logged 26354 in the 20 row without even taking the car to redline (on a flat road)..

the apexi map sensor is not a 3 bar map, its something more like 2.7 or so as it maxes out around 24psi give or take.
guess the question here is how much boost are you running to max out the scaling?
are you maxing out the sensor voltage (pim volts)?

Id have to look at the log again for the pim volts, but after converting the kgcm2 to psi, it looks like it might be time for a 5 bar sensor (23-24 ish). Im running off wastegate pressure and havent even got to adding a boost controller yet. #3barfail

Any suggestions for a 5 bar sensor?

After checking the log again, I logged 23 psi at 4.6v.. So adding a booster controller will be a bit too much for the 3 bar..

aem 5bar is a nice unit...readily available from most vendors.
