K4Tuning Posted July 15, 2022 Report Share Posted July 15, 2022 Hey all I have an evo 9 with G4X plug and play ecu. Getting things set up nicely and will soon be tuning on the dyno. Setting up my fail safes. Whats the most simple best way to set up a failsafe map using my fuel pressure sensor in the case that fuel pressure isnt where it needs to be, or if fuel pressure drops it has a limiter or a cut so it doesnt run into a lean condition? I would also like to set up a similar fail safe map using my oil pressure sensor. I feel like both of these maps would be similar in set up correct? If so what should i use to best set up my maps, MAP vs RPM or something that works better? Let me know what you guys are doing thanks!!

essb00 Posted July 15, 2022 Report Share Posted July 15, 2022 1. Use the RPM limit - 3D table (with differential fuel pressure in one axis). 2. Use GP RPM Limit for oil pressure. Samples below: K4Tuning 1 Quote Link to comment Share on other sites More sharing options...

Use GP RPM Limit for oil pressure. Samples below: 60 kPa oil pressure is about 8.7psi.. (I use psi..) My Idle Oil pressure is at ~200 - 260kPa. So unless I am reading it wrong you letting your engine rev to 9000rpm with only 8.7psi.... I have Oil Pressure / rpm table. ( limiting rpm) Fuel pressure / MGP, since I have a rasing rate regulator (turbo) (limiting rpm) Lambda / MAP ( removing timing) Here are my tables.

I think i have the info needed to create a few good maps now! Quote Link to comment Share on other sites More sharing options...
essb00 Posted July 15, 2022 Report Share Posted July 15, 2022 @remski2 As I mentioned, those were samples (I just made those quick, as my tune files are on the other laptop). I surely got the tables setup differently in the actual tune file in use. Quote Link to comment Share on other sites More sharing options...
