Yes, there was a similar glitch on rev 2.2, but no big deal--pretty easy to figure out.
BTW, I'm currently tuning the same engine, we should stay in touch and compare notes! Are you on Discord as well? I created a M50TU sub channel under #hardware

Also, will you be creating a basetune for 202207 ?
Fixed. I'll add 202207 tunes in coming days. But using 202202 is fine, because there hasn't been changes in 202207 that would need addressing in tune side.

Hello everyone

As currently it is difficult to get some parts for some of boards, anyone has idea what i can use for VNLD5090TR-E replacement?

I'm not very good at such electronic stuff, but i found that there is single channel version (VNL5090N3TR-E), and i wanted to ask someone smarter if i can use two of them as a replacement.

hello! I'm attempting to add an oil temp sensor to the speeduino on the extra input channels, do you need to soder in an extra resistor (pull up) to the board to do this? or should it just work? have it all setup but it still seems to not be working right.

so i can say, it works good

got a question
installed pnp board to pre facelift m43b16, it has only two outputs for injectors, paired as it is in firmware, it works flawlessly right now
can i just rewire injectors to separate channels and just change "Injector Layout" to "Sequential"?

Hi, I'm going to assemble speeduino v0.4.3 rev.2.1 for a M40B18 e36 motronic 1.7. And I don't know what is the benefits to the hall crank sensor.

What is the most common "hall crank sensor" swap? Can I get it from other bmw and put in the same wire hardness?

Thank you very much!

Hall sensors are usually easier to get working without problems. But if the stock VR works fine, I would just go with it. Cherry hall sensor with adapter is common alternative.
