  • Do you guys know what code 2279 and 152c are?

    I’ve had that code come up several times now and I can’t find any info on it. It’s usually in the morning when I first start the car. Shortly after the first start it will start misfiring and run rough, then when I restart the car those codes pop up. Once cleared the misfires go away and I won’t get the codes for a few weeks. I want to say it happens every time I fill up with 93 + e85 blend but can’t say for sure. Any one else with those codes?

    • I have the same issue. Google search reveals Vacuum leak, PCV Valve or hose cracked or leaking which highly doubt. I really have no idea. I am really starting to think our cars don't like E85. When I run 93 octane only for a bit. All is well, till I put e30 in the tank, then CELs stream in along with rough idle and performance. Really strange.

      • E85 with the platform is hit and miss. Creates a lot more stress on the fuel system and to a lesser degree plugs. If it's causing issues just keep lowering the mixture until they stop.

        • What is the recommended spark plug and gaping for this platform? A tech from Weistec recommended the NGK SILZKBR8D8S Iridium Spark Plug and stated although for BMW works great on the C63s. Any thoughts? Should I just replace with OEM original plugs from Mercedes?

          • On the plugs OEM are fine but close the gap down to 0.020 - 0.022".

              • E85 Mixtures?

                Hey guys!

                New to forum. Recently purchased a 2016 c63s. Through a catback exhaust and k&n filters on and expecting the JB4 tuner soon. Curious what are the recommended tunes for E85 mixtures and what are the exact mixtures for what tune?

                Looks like there's a map for 30% E85?

                Is there map/tune to run full E85? Is that possible with stock fuel pumps/injectors?

                Comment


                • The most you can run is around a 30% mix, but fuel pressure can be an issue. I'd start with 20-30%, map2, and log to evaluate it.

                  • Hello.

                    Has anybody had an issue where installing Jb4 on 2019 C63 AMG caused active brake assists functions to be disabled/limited including active suspension faults?

                    Had new wheels, *********, and JB4 installed. I don't see how the first two could have anything to do with something electronic.

                    Any ideas?

                    • You can unplug OBDII and remove it off the CANbus all together for testing but don't see how it could be related. Seems more likely something was knocked loose during the wheel/exhaust work.

                        To confirm, JB4 had nothing to do with it.

                        Took it to Mercedes this morning is it was a fault clock spring.

                        I'll be shooting over logs to you after this Tuesday.

                        It's a 2019 C63 so it has the new 9 speed.

                          • Has anyone purchased and ran the WMI kit?

                            If so did you run the car and or put it on a dyno?

                            If so what were the results?

                              Terry, can you elaborate on this? What issues and at what ethanol %, which maps, etc.

                              When you say stress, are you referring to high fuel trims or are there specific mechanical components you have observed? I just like to know what to look for.

                              FWIW I personally have had great success with E85 on this platform. I run it every day on map 4, for a year. Usually at 25% mix. I have never had a error code or miss fire related. I did do a lot of data logging and Review of the logs when I 1st set it up to make sure there were no problems. I had noticed that when you get to 30% ethanol, the trims start getting really high and/or maxing out on.maps 4 and 5. I would not recommend going quite to 30% on thise maps based on my experience, that looked like the ragged edge of the fuel systems capability to deliver enough volume.

                                  The fuel pump just can't keep up on all models. E30 works great for some, on others even E20 causes a fuel pressure drop. So it just comes down to being case by case. In most cases E30 map2 for example will work fine.

                                    • Current Maps for GLC63

                                      It seems the maps have changed since they were first posted in this forum versus the instructions currently shown on the Burger Tuning website. Can someone please confirm what the current maps are? i don't want to put the car in "valet" map and accidentally pick a map that is expecting racing fuel or something.

                                              • Hi Guys, i'd like some feedback on this log.
                                                New jb4 install on 2018 GLC63s running a custom tune and bmc filters.
                                                Run is on pump98 fuel and octane booster here in Australia, feels strong. map1.
                                                seems pretty rich to me but looks ok?
                                                Want to run an e85 mix and try some other maps, thoughts?

                                                    • All, new to Mercedes and also new to Burger's JB4. Car is a 2017 MB C63s, installed the JB4 and CAI yesterday. (Previously installed Dinan tune on M3)

                                                      After going through the CAI/JB4 install instructions a couple of times, I can't see where the passenger (LHD) side MAP sensor off the factory air box goes. See image

                                                      I feel like I installed everything true to the instructions but something is missing.

                                                      Getting several error codes.

                                                      Thanks in advance.
