And yeah publish away, most of it isn’t my work. Like 95% of it is comma ai‘s opendbc project.The UDS (also called ISO 14229) stuff isn’t that complicated but it does seem so when you see how much is going on with the network. $22 Requests and $23 requests are generally the same but $23 can...

https://1drv.ms/u/s!AhBoOw0Dk7RendhU-LO36pW5_TP1jALoad this in dbc file manager. This is what I’m currently messing with, there’s still a ton of incorrect values but I’ll also send you a log so can see what the data looks like. Tick interpret frames and overwrite frames. This file is sniffing...

Yeah, comma ai has the dbc files i started with, but dbc files are not public so people reverse engineer them.0x23 or $23 requests are through the UDS protocol. I think the easiest way to differentiate $23 from the 0x22 (or $22) requests is one is looking at a voltage normally ($22) and one...

This is what I see, but there are about a dozen CAN IDs related to speed. Some in kph, and some in rad/s.

What I meant was something that requires low post event data manipulation. Something like racechrono with full CAN-bus + OBDII logging synced to video + my racebox mini. Currently, I just use racechrono for video + lap timing (this is honestly all you really need). For data, I either log the...

Yeah it will give a lower resolution result when you shift the value instead of using the 2 bytes of data, but it's not a big issue if you don't need high resolution values.However, I mainly wanted to point this out since you described "saw-like" data. The "saw-like' data is a counter and...

I can send you the dbc file I’m working on, if you know how to work with them. Just quickly looking to see how yours compares, 0x415 for example. The first value is 16 bits, not 8 bits shifted 8 bits. My big issue with the CAN bus is I can’t find any engine data like spark, knock, fuel trims...

Deleted. Got impatient and answered before fully reading everything.Do you have a pic of the rashed up tires and/or the alignment number?

Yeah the problem is the old cars has HSCAN 1 and HSCAN 2 read through the 14 and 6 pins. Then had MSCAN on 3 and 11. Now HSCAN 1 is on diag 1 (14,6) and HSCAN 2,3,4 and MSCAN are on diag 2 (11,3). Connecting to both busses is fine, just messy. Do any of those CANcrocodile things (contactless CAN...

The CAN network changed (I think) for the 2020 model. If anyone has had luck, did you have to splice the CAN bus or is everything accessible through the OBD connecter.

I think you guys are mixing up weight distribution with aero balance.They only way suspension will alter your AERO balance is if there’s a change in ride height difference (front to back). Adding rake (larger drop at the front vs rear) will increase the weight over the front wheels and make...

The only thing suspension can do to alter aero (disregarding exposed suspension cars), is rake and underbody aero. Regardless, I doubt either would be significant on a stock car.

Also in case anyone is wondering, the pattern is the same on the backside of the bottom rotor

They were turned at Oreilly, but I’m not sure what they use. Im not planning on using these rotors o the track, it was more of a troubleshooting attempt.Is there any reason why this pattern could occur on both sides due to an issue with the caliper? It’s just a single piston floating caliper...

This is the result of bedding them. As you can see 1 of them is consistent and relatively uniform, but the other is not. And yes, I repeated the process and drove around for a week or so. The sounds were apparent before and after I replaced the pads/rotors.
