    Great data on the IATs. On track I think I'm usually 10-15 degrees hotter than ambient which I'd guess is closer to the track surface temps?
    That's it in my office haha. So we got climate control

    It might not matter in your case, but the CSL DME programming is expecting the IAT sensor to be in the factory position behind the radiator.

    Since your sensor is upstream, it could in some cases be predicting too low of an IAT causing knock and timing pulling when not at high speeds. It appears that putting it upstream into colder air perhaps counterintuitively puts you at higher risk of knock, thanks to the decompilation with from karter16.

    I have a friend who works at a refinery, and he said he can test my oil for me. So I got a UOA and a VOA for him to test, never done anything like that. I'm too much of a scatterbrain to usually do the Blackstone thing. This is the oil after the one dyno day and track weekend so curious as to how it will look as far as viscosity. Since the OE bearings don't have copper and lead idk how you can do analysis for wear.

    I also unfortunately went a little too crazy with the gold tape, but "racecar".

    I did try and validate IATs as well. When it is parked, disaster. It easily gets 50 degrees hotter than ambient. Untitled by Sam DaJam, on Flickr


    When moving though, it is a better story. It is within 4-5 degrees from Ambient. It cools down relatively quickly. I'll double check next time I'm on track what it is doing but I am very happy with this. Just the CSL bumper feeding the factory USDM duct shooting air into the evolve elbow thing, with the wheel well blocked off with tape.

    Ambient I am using the factory outdoor temp sensor.

    I installed my old tune I made in my E28, and I am back to enjoying driving that thing around more. So far the M3 has just been sitting in the garage until I know I am going on at least a 45 minute drive and then I pull it out. I want to redo the exhaust I think. It is pretty loud, I'd just been driving it so much I got used to it.

    That window breaking sucks! Not sure if applies to E46es but I'd clean the door/window seals as best you can to avoid tiny scratches in the new window from broken glass. BTDT on an old Japanese car with felt window seals.

    Yeah I was shaking the door pretty aggressively, gonna let the stiff springs and MCS shocks hopefully get the rest out.

    The rattle was prior to all this, but never really investigated that. I won't know if it's gone until I drive it. Waiting on those clips rn but need to drive the E28 anyway so just leaving the M3 in a buddys shop rn

    Oh and now I'm waiting on $50 in clips for doorcard and the door trim thing. Usually very good with clips and not breaking many, but man this time all just shattered. Very fun.

    I will never get all the glass out of that door. Pain. A local buddy delivered me a piece of untinted coupe glass.

    Vacuumed for probably 45 minutes. Another 30 minutes just removing the glass from the front rubber insulating piece. Just a pick, I had to use my phone camera and flashlight to see what I was doing. But anyways after that went to put glass in, realized both sides of the top window rubber seal had to be removed.

    I think the adjusting procedure is an absolute fiddlers fuck. I think it's okay now. Goes up evenly, seems to decent tension, goes under the seal everytime. Door doesn't take too much force to close.

    There is the slightest airgap at the bottom where the glass meets the B pillar, and the glass comes out of the door with it all the way up. I give up. It also doesn't park at the very bottom like it used too. Glass protrudes ever so slightly from the door when all the way down but I give up for now.

    As why the glass broke? There isn't a smoking gun. The window did rattle, checked the regulator nuts that are common to cause a rattle. Non were more than a 1/4 turn loose at most. Idk, whatever think it's at a point where I can leave it alone for now. Very glad I removed a spare window reg from the yard, and broke the glass to get it out there as everything was assembled so I knew how it went back together. It all fell into the door

    The Goodyear 3Rs are about 1 second faster than Falken RT660s and R7s are about a second faster than 3Rs. At least for me, probably 3 seconds in R7s considering I left some time on the table learning.
    Good to hear! I had similiar findings with R7s on my E28. Before it started cracking all unibody and strut housings in half 2-3 seconds

    I want to leave car as it is, start playing with rake and tire pressures before gripping it up more. I know a 43 is possible, but is a 42 possible? On Rs4s?

    Long term goal, break into into the 40.xx with 245 Hoosiers.

    No aero, 330whp, 245 Hoosier R7s.I believe 3300lbs. I'm sure MSRH has degraded lot since then. This is a 1:40.805​. But the 11 year old youtube video gives me something to chase

    Close call avoiding spin:
    Timestamped Link:




    1:44.70

    1:44.53


    1:44.66 Same pace but with much more understeer on the LF, tires degraded overall

    I cleaned the car for the track event.

    For the ducting, all I did was duct tape the wheel well opening for the brake duct shut. So that still isn't ideal but all I really had time for, so just did that. So it is getting air ducted from the csl inlet, into that factory airbox feed duct. That basically shoots it into the evolve opening, it just isn't insulated at all.


    I had new RS4s on the car, really was just excited to test the alignment changes. As well as test the new airbox and tune. Prior to this my PBs in both directions have been 46s, with the goal being to get the car into the 45s on a super 200 tire. I had no expectations of setting any PBs.

    On the first session on lap 3 dipped right into the 44. The first hot lap.

    Did it again until the ambient went up.

    The Epic tune has made the car so consistent. The mph is the same, for a session. It did decrease throughout the day as temps increased from 50s to 85. However, it was the same for the whole session relative to pace. It is also just way punchier, most notably the 3-4th shift. Just seems to have a lot of torque there at that rpm. The alignment greatly improved turn in and power down while complimenting the cars current balance. I think that was one of the biggest changes to it.


    The knockback was pretty bad, and my LF tire was getting noticeably worse. So I jacked it up and found the RF wheel bearing was bad. So later that night did some asking around and found some takeoff Core4 front wheel hubs with not too many races on them. They're just regular skf/fag wheel bearings with msi press in studs.

    I ran out of time to check the alignment after that it was midnight. I did find the issue with the LF though, I had been running this RS4s at 37 psi hot. It was overinflated and just destroying that center rib in diamonds edge under that combined loading. I am now targeting a much lower number and it seems to work better but the damage to the tire was done.

    The morning session was frustrating with traffic, and I really wanted to do a 43. Unfortunately I was staring at the laptimer. I gave up, and just started chasing some really good drivers in the instructor run group and

    I had to avoid a spin and tested the bumper mounting.

    Only problem with car Sunday was my drivers windows glass broke. I gave my student a ride along, when I went to get out of car and check tire pressures. Window shattered in the door. idk why yet.

    So drove home with no window. Made phone calls difficult with the bimmerworld exhaust lol. Drive with the elbows
