j.mendoza Posted May 10, 2018 Report Share Posted May 10, 2018 I'm using a 3 bar MAP. I have hit the MAP limit today on 2nd and 3rd gear. When I tried to do a 2nd and 3rd gear pull, the MAP limit gets activated before around 4000 rpm. The boost table is set to 13.1 psi and the MAP limit mode is set to fuel%cut, 2D table, ECT axis setup. I can post the log file if needed. The log file is a big file 11MB. 94 mr2 WORKING.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2018 Report Share Posted May 10, 2018 It is not clear if you are asking a question or just making a statement? Your MAP limit is activating because your boost is reaching the value set in your MAP limit table. The MAP limit default control range is 10KPa if advanced mode is turned off so yours will start to limit at about 31.5Psi absolute. Note you have your boost target table set up with MAP on the axis, so that "13psi" is actually absolute. You will have a hard time targeting a boost level below atmosphere.

j.mendoza Posted May 10, 2018 Author Report Share Posted May 10, 2018 How should the boost target table be adjusted so that if I want to target 13 psi of boost on pump gas and 25 psi when using race fuel? Do I need a separate boost controller to hold the boost target desired? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 10, 2018 Report Share Posted May 10, 2018 I just changed my original post here. Im not sure if the ECU is actually doing any boost control in the screenshot above. Can you share your log file on google drive or onedrive etc. Quote Link to comment Share on other sites More sharing options...

j.mendoza Posted May 13, 2018 Author Report Share Posted May 13, 2018 Hi Adam, Have you had the chance to look at the log file? Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 13, 2018 Report Share Posted May 13, 2018 Yes, I just took a look. It appears that your boost control has not been set up correctly at all, the WG DC table is not even close and the boost target table is aiming for vacuum... I suggest you switch it back to open loop, then get the WG DC table tuned properly to achieve something close to the boost you want to run. You will need to fix your boost target table also. You can then switch back to closed loop and tune further if you wish but for most users open loop is easier and plenty good enough. Quote Link to comment Share on other sites More sharing options...
