Great stuff! It gives me hope that someday I'll be able to dissassemble my SIM2K ecus. Still a long way to go though! I'm still way better in winols

Hardest part is getting the ball moving. Then it slowly falls into place

nice bro thanks for information

[@GHIDRAuto]

For sure man.

Sounds good

[@scottlecky1988]

I'm guessing the 3600 value at 9:00 in the vid is one hour (60sec x 60)

[@GHIDRAuto]

That’s interesting. Likely! Thank you.

[@Stack28x3]

Genial genial... Thanks

[@poet99999]

@4:20 if thats the isuzu, its because there are two speed sensors. A primary and a backup But if you found the speed PID, think you could adjust for different gearing?

[@poet99999]

Nm... You answer at 7:30

[@GHIDRAuto]

I would like too agree with your logic about the 2 speed sensors, however both speed 1, and speed 2 are unquestionably being written by the same value. If you are who I think you are. I Dug through our 06 wiring diagrams, and unfortunately the speed sensor is wired directly to the Speedo. The 07 dpf trucks and newer are communicating speed via canbus, so their speed could be manipulated via the 3600 value, or the 1.6xxx value. I could attempt too read the Speedo’s processor if it has one. Take yours apart and see if it has a micro processsor or just a chip? Might find a potentiometer or a resister could do the trick

[@poet99999]

@@GHIDRAuto yeah its me, idk i remeber looking up the VSS stuff a while back but kinda came to a road block, then lost interest. But if its a hall effect VSS, then it will be algorithm based... Probably

[@GHIDRAuto]

Copy. Well, if it has a processor, maybe I’ll try to read it.

[@stevensgarage6451]

I want to adjust my cruise control tables. Have you found them or is it tied to the injection quantity like speed limiter

[@GHIDRAuto]

I’m not actually a tuner. This is my first time, so I don’t have any knowledge of how the cruise control tables work. However in the 4 denso ecus I have looked at. Isuzu, Nissan, and Suzuki. I have been able too find the sensors, or switches by finding their dtcs “ckt hi, ckt low” and then tracking down the inputs from there. So I guess make some assumptions on what could be your cruise control tables, label every ram address’s(or rather functions that handle them) associated with the cruise control, ckt hi lo dtcs, obviously also brake pedal. and then start tracking them too eachother

lol just making this shit up anyways man. somebody should hire my just so I stop making these videos 🤣. but in all honesty I have nothing but clues, not proficiency at all.
