OK thanks. So do I set it up by driving the car with the laptop on data logging and seeing what the map sensor reads? No need to guess. Key on, Engine off, it should read atmospheric, and in most cases this should be 100kpa, 1 bar, 1000mbar....whatever units are in place. Get a mityvac or other known pressure source and apply pressure to the sensor to ensure what you're seeing at the ecu, is reflected on your known pressure source. Likewise for vac. Many ignore basic setup stages and just assume these things. It probably is correct, and probably bas been done....but always nice to know 100%. I've seen far too many bad ecu setups over the years, to wonder WTF whoever was there before was actually doing. And worse, charging people for it ! But given your table does only go to 120kpa, this will need extended for any usable boost. 9.85 @ 145mph
