Permanently disabling auto start/stop
I would consider the GAP tool, but I can't justify paying over $500 to solve this one annoyance. I really have no other foreseeable needs that I would use the tool for and if it is VIN locked I couldn't use it to help others. @stevemfr if you want to sell a "one file only" version for $100 I'd probably be willing to do that, although I am also concerned that future OTA updates could change or invalidate a back-end CCF change (not likely, but possible).
I have moved on to looking at the CAN bus. It seems like this might be the best way to fix it. A small custom PCB with a tiny MCU and a CAN transceiver chip (like a MCP2562FD) that plugs into the ODB port and just sends the off command at car startup. That seems like "a better way to push the button"

It would be a hard pass for me on any future vehicle purchase on a vehicle that has had CCF coding done to it. Past owners monkeying around with "Custom Programing" is one of the key reasons to get a PPI done on a vehicle before purchase.
You sure a PPI will pickup CCF modifications? I highly doubt it's part of the standard PPI checks.
Chasing Amy, the finger cuffs scene. You will never know..
You'll need to tell the person doing the PPI to compare the "as built" file to the CCF in the vehicle...

BTW, the IIDTool is not VIN locked for normal diagnostics; only special programming functions and functions surrounding lifting or lowering the EAS are VIN locked.
I can understand your position - though I am willing to bet that you'd find numerous uses for the IIDTool especially over time. I hope you can understand our position too: getting to where we are now required quite an investment and we can not afford to sell the IIDTool for less. It's actually only comparable to diagnostic systems costing 5 + times as much.
Yes, your product is very reasonable for all that it does and I have nothing but respect for the investment and energy required to bring physical product and software to market, especially to support a niche community like JLR. IIDTool is in a totally different league. I design embedded systems and software (for rockets not cars) and would never consider creating a "consumer" product given the effort, support, and investments required to productize it and satisfy Joe Public. That said, since you guys are already in the business you might consider creating a super low cost "single use" device that does not require the same iOS/Android app investment or technical support -- like a small ODB dongle that shuts off auto-start/stop on power-up. I bet a lot of people would pay $100 for that but would never buy the full version of GAP IID. It would be opening up a new market with little overlap of the existing market, assuming you can get the volumes you need and the margin economics to work. Food for thought.
This forum is hostile. So far, as a group, we've managed to run off The Insider, that guy in Houston that manages a Land Rover dealership who was extremely helpful, the guy from Plumb, and a couple others that I can't think of right now.
This is really not personal @Mojave. Please don't take it that way. It's really a group thing.
