Hi, I’m having problems with my L67 supercharged Buick/Holden commodore. While trying to sort the over fuelling/hot starting problems I have developed an error code for ‘MAP limit reached’ which cuts in at 3000rpm, the MAP sensor is showing 190 kpa, map limit is 200 and cut is 10 before so not surprising but the supercharger pulley is only good for 10psi so I’m fairly confident that (unless u have my kpa/boost psi conversion wrong) some thing is a miss with the map sensor reading I have tried switching from my Link 3 bar to a GM 3 bar sensor and carrying out all the necessary calibrations but the same pressure shows, So fairly sure it’s not the sensor itself. Once warm, restarting the engine is nearly impossible as it floods itself, I’m guessing due too the high/inaccurate Map reading? any ideas? Is this a possible Ecu setting issue that I may have inadvertently changed since it ran correctly or more likely a wiring issue? I shall upload a log shortly, if anyone has a L67 base map I could compare also that would be great! Cheers, Jim Log 2019-02-10 8;32;24 pm.llg
