    Curious on people's thoughts on how this looks.

    Looks like you need a little more fuel pretty much everywhere and you need to tune your AFRs very much below 3500rpm to protect your new motor. In about 600 rpm, you’re swinging from 12.5 - 15.5, this isn’t a great tune for your mods

      appreciate the feedback. a little surprised since randy did this tune. he's pretty on point.

        Just going by the data plot above. I have the same (with flap) mods, it’s not trivial to tune out the resonances. Here’s what my AFRs look like after DIY wideband tuning. Just data points from a couple WOT logs, no smoothing or anything to make the curves pretty

          I think I previously posted these files on M3forum but don't see my dyno graphs on this forum.

          Stock motor on 12-11-2014. Mileage: 155,530.

          Stock motor on 7-19-2019. This was my baseline. Mileage: 164,439.

            30 HP from headers and a tune is solid. Just picked up a set of Megans.

              Indeed. For ~$800, these motors can pick up ~11% more HP. On a dollar/HP basis, catless headers and a tune are probably the most cost-efficient mods for increasing power.

                Dyno day tomorrow. This build has taken me over a year and a half since my last dyno. Feels like forever.

                Here's what I did to prepare:

                New o2 sensors
                Full valve job
                ICV cleaned

                Crossing my fingers for good results and more power over the street tune we just did. Car feels really good, feels as fast or faster than my E90 M3 slicktop with lightweight wheels, intake, exhaust and E85 tune (cats still on it). Should be coldish too, 50-60F.

                  spec?

                    Hopped on the dyno for some tuning. 2005 with 167K or so on the clock. Every engine sensor, VANOS rebuild, Valve adjustment, fuel pump, filter and regulator over the past year or so. New OE coils and plugs and upstream O2s were the final touch.
                    • Turner CSL Style Intake with IAT in plenum
                    • Megan Racing Headers
                    • OEM Section 1 and 2
                    • SS Race Muffler
                    • Epic
                    • 93 Octane
                    • OEM 19’s and 3.62 gears
                    Weather was 28F and dry. So cold, we didn’t want to deal with fans adding air pressure at the intake.

                    SAE smoothing: 313hp @ 8,200; torque was 243 at 5,200

                    Driveability is as good or better than stock, even partial throttle.

                        Badly. Wasn't able to get any good charts because had a spark issue and the car misfired on the dyno. Went home and put in new coils and plugs, car runs super strong and smooth. HTE says the tune is done and no need to touch it up so I guess I have to schedule another hour of dyno time if we want meaningful numbers.

                        Honestly, I am pretty disappointed and this is why I told someone else in another thread to ALWAYS do coils and plugs before a dyno day/tune. I would like to go back but feel like HTE should continue tuning it. Anri said that perhaps HTE loaded up a full power tune and it's at 100%.

                        I also would like to Dragy the car and get 60-130 info + 1/4 mile trap speed to see where it's at.

                          Megan headers (swaintech coated)
                          BW race with straight section 2
                          Injen intake
                          Paul Claude tune

                          I’m really surprised, was expecting lower. This kicks me out of NASA TT4. This actually kind of screws me because I setup the car with ballast. Now I need to un-setup the car.

                          Probably can get more since the car was on the edge of overheating.

                            Nice! I was expecting a fireball to shoot out the exhaust

                            How many miles on the engine?

                              About 101k miles on the motor, not the original. 8k old plugs, sensors, and stuff. Only thing relatively new are the cam sensors.

                              It used with the Evolve tune and the Martyn ECU tool but I think the PCS tune eliminated that.
