Track forum general chit chat.

Warranty depends on the dealership you go to and the technicians you know
Around here there’s a few you have to request that “get it” with track cars because they track too

If you can schlep two sets of wheels/tires to the track (drive the to track on the RS4s), then go full send on the RS4s. Explore limits of adhesion at lower speeds if the traction has dropped off but predictability is still there. IF they chunk, then swap for the RE-71Rs.

I ran Toyos RA-1s and then NT01s in the Jurassic period. Fast lap was when they corded. Every time. That was a nice perk as you did not worry about running them to the cords.

This is probably what is going to happen. My te37 street wheels are on Continental extreme contact sports. If the rs4 decide to retire early, I'll swap in the street wheels for later sessions if I am up for it.

I think dparm and a few others definitely spoke about the lower limits to hone the skills at the edge of the friction circle. I dig that too. 👍

Do aftermarket brakes or suspension void a warranty?

No, but the dealerships probably won't want to try diagnosing problems related to those parts, let alone fixing them.

I kinda figured so. And that makes sense. I think it would be nice to utilize for the power train more than anything lol

ppl,
I need volunteer testers with E92 M3 DCT with Aim connected on the CAN bus

Post this on the Discord too.

///Mobbin do you know if that MaxxECU guy knows if the same byte address works for 6MT transmission temp? or if not, what the byte address is?

Derbo, sorry to say but I highly doubt the 6MT temp ID/byte is the same value as DCT. DCT has a ton of stuff you can read off it and my guess is all that stuff is custom to the TCU for the DCT and provided to the CAN bus by the TCU. 6MT likely has no TCU I'd imagine? Also, based on my limited research MaxxECU also seems to specialize in DCT in particular and provides the ability to have a completely custom independent DCT controller, impressive stuff. Perhaps one day one of us will integrate their controller/setup.

I would ask that folks not go bothering the MaxxECU folks again, at least not right away, they were extremely generous with their time between rhyary and I and I'd hate if we burdened them further besides interest in their products of course.

One tip they gave us is that it's quite easy to snoop the CAN bus and figure this stuff out on your own, just need to find someone that is familiar with doing that and has the equipment for it.

Sorry I can't help more on this one!

I suspected it wouldn't be the same. From the conversations I had with dparm and looking up the bmw technical training pdfs, it looks like the DCT Module handles temps and the mss60 actual handles the temp for 6mt cars.

Oh well! I am curious what tools are needed to read canbus signals. Might be another rabbit hole to dig my brain into.

derbo here is another tip that came from Maxxecu (with some of my thoughts thrown in). Get setup to snoop the CAN bus, I think CAN is likely on obdii even so shouldn't be that hard. Run BMW Tools INPA, likely have the ability to read the 6MT temp in INPA, start the "snoop" of the bus, read the 6MT temp (go to the place in INPA that shows it), stop the snoop. Then you'll have a log of bus activity that you can read through, the car is always going to be sending lots of traffic on the bus, but at least some of what is in the log will be requests for the 6MT temp CAN ID/byte. Could even take another log when you are not reading 6MT temp and compare the two to see what is different and determine which read is the temp.

Hope this helps!

Thanks rhyary ///Mobbin !

Reminds me of packet capturing for network devices for work The information looks similar to packets in networking OSI layers. Should be cool/fun to do if it doesn't require too much money haha. I

yep, exactly like Ethernet/TCPIP with one big distinction. For me anyway.

One is a way to make money
The other is a way to spend money.

I will let you guess which is which.

Haha.

Well, knowing the temps of the transmission might be a good thing to save money too. I might have to read up on this and see what hardware is needed.

I need volunteers to test a new PT6-test2 profile

I have some front used DTC-70 pads for sale if anyone is interested. Ran for 1 day each, and at least 1 day left on both sets (I have 2 sets). Fitment is for the Brembo caliper and pad size is intended for stock rotors but can be used on larger rotors.

$50 a set please

I need to check my dtc 70 part numbers. I have the GTS kit front and rear with 365's up front

If these fit I'm a buyer.

[Tommysalami]

I have $150 in Hawk certificates that have to be used by January 31st if anyone's interested at buying them from me for a big discount

Felt good to be at the track again for the first time since beginning of October but I got a nice reminder to always check the work done by shops and never trust when they say a strange sound is normal after installing aftermarket parts…

My student yesterday had MCS 1ways installed with 18x10 wheels and 275 RT660 tires since the last time I saw him. Since I am well accustomed to these cars I asked if they made the provisions to fit the front wheels. He said they did and I took him at his word, but when he started driving I heard a strange spring sound (like one perch was rotating and the other was not when turning the wheel) only coming from the left front which the shop told him was normal. I brought him back in and pulled the wheel. The left front tire had spun the locking perch until it bottomed out, all of the while carving through the tire.

Luckily I happened to have 5mm spacers in my bag, and the tire carving hadn’t gotten too bad. Spooky stuff though.

[Bimmer Barney]

Someone will undoubtedly disagree but thanks for posting this. I am a firm believer that you have to check all your stuff yourself, or by someone you trust 100%, every time. I learned this when racing motorcycles because on a bike there is little to no margin for error. Something goes wrong, you crash almost guaranteed. Cars have a much higher margin for error, but even still the results can be bad.

It's also why I am a mechanic and not a carpenter. Instant feedback when something isn't done right, can't cover up mistakes with caulk and paint.

[Move Over]

One of the last alignments I got I asked him to torque the SPL locking nuts to 140inlb, he said I don't have an inlb wrench but I have a well calibrated hand. This was at a very well known shop too.

I get it home (fortunately just towed), and they were all under torqued. Some even under 100inlb. Some to 65-70. I realize he didn't want to snap them, but if I didn't know any better, it could have been ugly!

Check your stuff, paint mark it, become (somewhat) self sustainable in track prep. Could save your weekend, your car or even your life. Especially in this day and age where quality work is very hard to come by. I'm baffled at some of the crap I see around here.
