Re: Help getting started NVRAM tuning

that is for people that dont have nvrams and want to edit stock memcals the slow and original way with offline edits and in a chip programmer.

Re: P10 and P12 Primary CPUs

You mean the E40, right? Its usually address 14 I think, but the hard part is getting the PCB out to locate the flash chip. I dont know how to do that. The slave sounds right, I don't have a reference right now. That zip has all the 68k and ppc variants that were sold to the automotive market for pc...

Re: P10 and P12 Primary CPUs

Yhey are iterations so we never got to know the exact cpu type. We've only observed that they changed around about 2000 and can run some options with less alignment to avoid crashes. There is a file MPC500_M68300_CD_ZIP.zip (yes exactly like that) that you can get from NXP here https://www.nxp.com/p...

Re: Coding my own aftermarket ECU

C compiles to machine language (usually, in the context of MCUs) so you get a higher level language without an abstraction layer in an OS.

Re: Coding my own aftermarket ECU

Hmm thats interesting. I thought arduino was all C on bare metal. A quick google found me this https://forum.arduino.cc/t/is-it-possible-to-use-mbed-os-instead-of-arduinocore-mbed/1162356/ and also a few notes that say mbed goes end of life mid 2026. So I think you may have 3 opions. mbed, arduino c...

Re: Coding my own aftermarket ECU

It can only be a race condition if you have things running in parallel, eg one in the main thread on the main CPU and code in an interrupt handler that can interrupt the main loop and run something else. Or an MCU with 2 cores and you have code running in both. Since its bare metal there is no opera...

Re: Help getting started NVRAM tuning

yes you have to use 12p bin and therefore 12p xdf and adx on the NVRAM. Its the latest factory operating system for that computer, so does everything the other and older ones can and has more features and fewer or no bugs. Those other ones do not support realtime or high speed ALDL communications an...

Re: Help getting started NVRAM tuning

the xdf is the definition for the bin. bin without xdf will have nothing to change in tunerpro. load the xdf and then tunerpro what is where and how to interpret the data. thats why it has to match. you can download a bin, edit then upload. and you can use realtime and edit and have the changes go t...

Re: Help getting started NVRAM tuning

the bin file is the data that goes on the nvram. includes operating system and calibration. you have one on there by default, but you need a starting point in tunerpro that matches it. there are different ways to start but if you dont have a bin loaded all the tables look blank. and if you load it w...
