Lol, he asks money for this shit?
I would never pay him but on the other hand, maybe we should and then spread all the info for free to make him pay for his greedyness

But you have a job 1 car. So if it's only possible for job 2, he can't. What a douchebag, selling Forscan codes. If it's not only Forscan, I can understand he is charging money. Maybe he still does something with the turn signal wire. If so, don't let him play with that. Keep your wires original.

supposedly everything he does is software only. the person who originally told me about him mentioned that the guy says amber DRLs do not work on 2024 Job 1

Than I need a new list of codes to try again. Maybe I missed something..

i will be doing some looking when i get home. according to the spreadsheet, over 60 nybbles are not mapped to anything documented. also, yes, "nybble" is a real measure of data, it refers to one hexadecimal value, where "byte" refers to two hexadecimal values. "F" is a nybble. "FF" is a byte

here's a tip: the last two digits per address of as-built data is a checksum, and is a byte. so if the checksums match, there is likely no difference between the contents of the address, as a byte can have 256 different values

Yeah, this is exactly what I found out when I was documenting all lines between NA and EU. I just looked at the checksum to find out if there are differences or not. Same checksum, no difference in the numbers of that adress. Saved me a lot of time.

yeah, that works correctly because the that 300kmh one is based on the 180mph speedometer, which is used on the Dark Horse, VSS style 3

Oh, didn't know the Dark Horse has a higher top speed on the speedo, well I'm keeping it like on this setting too then haha.

this is pretty dead in the water, now. turns out, the GTD has a special version of the instrument cluster programming that replaces the Dark Horse's 180mph speedometer for the 220mph one. no clue why they didnt just fix up the already existing one. if someone braver than me wants to buy an FDRS license and program their IPC with SR3V-14C026-AC (GTD IPC software version), let me know how it goes. i wont dare try unless i buy a second IPC module in case i end up bricking one

The GTD that I compared mine with has the Dark Horse speedo of 180mph.
That's why I was happy to share this news with you. Turned out you already had the 180mph on your Dark Horse.

VSS Style 3

The GTD on this video has 220mph so this one is programmed to VSS Style 4 which is broken you said.

Also this GTD has the amber lights, so we need the VIN of this particular vehicle.
