HP tuner for a 3.0L Gladiator eco-diesel...

[aevgladitorrubi]

Before going down a rabbit-hole-- I'd like to see if anyone out there has any experience tuning a 2021 Gladiator eco-diesel with an HP tuner? I'm not a techy guy, but want to know whether it's worth it? Live in the greater Chicago area.

AFAIK they do not advertise it as supported yet. 2021+ tunes are bench flashes.

For those of us that don't speak tech speak-- what does that mean?

Sorry, I will be mindful of those things next time—work habits.

If you’re referring to the bench flash part then: there are many ways to go about updating one’s ECU. The OEM will typically go through OBDII port in your car. Some tuning solution also work that way but they have to break some of the ECU security measures: for example, negotiating the proper session key to talk to the ECU given a seed. Basically, it’s like if you and I know a secret formula, but you’d come up with a random number, and we would both calculate the result of this number through the formula and use the result to encrypt the rest of our exchange.
Anyway, once broken once, many devices will pop up as they are now able to communicate with the ECU like a FCA-certified dongle and access to standardized interfaces (SAE J2534-1). Most Chinese clones are copies of tuning devices, so they're essentially copies of copies of the OEM. Hence the poor reliability and support.

Bench flash means the ECU is not connected to the car and an apparatus is attached to a few pins of the device either through the connectors (Usually CAN HI, LO, VCC, Ground, and sometimes others depending if something can be (ab)used to gain higher privilege to write a new firmware to the ECU. Sometimes this isn't possible even (usually in the earlier stage of the ECU reverse engineering), and the ECU itself has to be popped open and probes directly plugged to the motherboard of the ECU, targeting the EPROM or other chips.

This is just scratching the surface and probably creates more questions and answers. Sorry about that. I'm still researching all this myself purely out of curiosity because I hate all the secrecy around it and not understanding what's going on. I don't necessarily want to do anything with mine.
