  • TMS Bluefin Stage 2 issues

    went to another rolling road day today, i posted this awhile back but didn't have as much info as i do now.

    this is my RR printout, only getting 253bhp. boost suddenly drops off at 4200rpm

    the RR controller said it was running lean at .9 AFR and .73 AFR.

    any ideas what this can be?

      Eh^? Standard is 240

      Stage 2 should be 270.

      The main problem is the boost drop off and retard.

            Actuator perhaps?

            Have you any logs from the ECU to see what the ECU is observing i.e. closing throttle etc.

            The AFR metrics provided won't really tell much unless you have a graph showing them and where the two lambda figure were observed.

                  Would a weak actuator cause a boost drop like that so sudden, can feel it and hear it in the exhaust note.

                    That would be my next step, should let you know what is happening i.e. the ECU perhaps closing the throttle for example.

                      Can a bluefin do this or is it a tec 2 job?

                        Tech2 or ******* would do the job nicely, Bluefin can data log but its not great if I am honest.

                          well i've fitted a forge FMIC and been out on the road doing some data logging.


                          heres a graph of my inlet temp and boost pressure. does this look right for a stage 2?

                            Looks like throttle closing to me. Was the fuelling read in lambda or afr as .9 lambda is lean but 9afr is rich.

                              it was done via a probe in the exhaust?
