    • Race Video: Stock E36 M3 vs. OE Tuning tuned E46 330i

      This video is from BimmerBoost member 3Fest who recently had his E46 330i tuned by OE Tuning. He tells us that some doubted his gains so he set up a run with a stock E36 M3 to prove the tune in the real world. The E36 M3 stock for stock is the faster car. Both cars are manual, E36 has a passenger. The video speaks for itself.

        Shorter gearing will give you more torque but for a shorter period. So, you will be faster up until the shift point at which the car with stock gearing will be accelerating faster since for example it can hit say 35 mph in 1st gear vs. 30 for the shorter geared car.

        If the car with shorter gearing could hit the same mph or had a higher rev limit to do so, it would be faster.

        Case in point, I went to 3.62 from 3.15 in my DCT, pretty large change. It helped my off the line and I was quicker through the 1/8 but at higher speeds where you spend more time in gear it became a liability and my car trapped a lower MPH. Make sense?
        Makes sense now. Thanks for the reply.

        Question regarding the rear gear change in the DCT - do you need to somehow "tell" the DCT logic box/ecu that you have a new ratio so it "knows" when it can safely downshift? For example [made up], in your case you would might now be able to go from 3rd to 2nd at 50, whereas before the logic would prevent the shift because you would be at too high of a speed to do so. I am assuming you need to reflash something to compensate for this, is that correct?

        Reason I ask is because I have been thinking of putting a 3.91 on my SMG M3 (e46), as I would like to be able to pass while crusing without a downshift. I have heard this is the cure - and I can see how that would work out. Also, down the line - I will be looking to get an AA supercharger (lowest level)... Does the diff swap make sense if I am going FI or would it be a traction nightmare based on your (or anyone else's) experiences?

        Yeah. Seriously, people just mouth off and really have no idea. I've noticed nobody on this forum really gets out of hand like that even if they do disagree. That forum is filled with HATE!

        It's not necessarily filled with hate, it's filled with idiots.

        Some guy actually told you to race a modified E36 M3 and then he would be impressed? As if impressing him was the goal? He should appreciate you showed a real world comparison, the video wasn't about beating anyone but showing the effect of your mods and an E36 M3 makes a good comparison.

        I can't believe they don't get it.

        I don't have any experience with driving fast cars, but I would think that shorter gearing is always welcomed in the acceleration department. Passing is even effortless on my slow 330.. I could only imagine an M3! I went from 2.93 to 3.38. YMMV when passing in 6th though so I am not too sure how that would feel..

        Yup that's true. They think I'm trying to make a statement about M3s even though I said repeatedly the M3 is obviously the better performance car. (i've had one, I should know!)

        With your powerband I'm not really sure but in my experience shorter gears hurt up top. It may be that these match your car really well.

        No, on previous cars like the SMG it would shift based on MPH which was pretty stupid. The DCT does it based on RPM. There was no need for a reflash.

        You will need a reflash for your E46 M3 to get it to work right in the auto modes. Do not get a shorter diff, traction nightmare. I'm probably going to go longer.

        Im surprised by the results. Please OP don't take this the wrong way. But, it sounds like the e36 m3 driver was shifting slow and/or slightly touching the rev-limiter.

        Yes I agree I was taken back by the results as well. I think without the diff, and a better driver the outcome would have been alittle different.
