LR4 IID Tool Updates

Been almost 10 years since I had an LR3 with an IID tool. My current LR4 shows a laundry list of updates, but unsure if installing them is safe, or necessary. I do have a reoccurring issue with my fuel pressure reg, which is an LR KB article and takes an flash to fix (unless its actually the fpr). Has anyone done all the updates? There is no chance that I can use the tool to flash specific LR updates, correct?

Thanks.

Generally you shouldn’t update a module unless there is a known fix in the software to fix a problem. Updating a high mileage TCM can burn up the solenoids in the valve body.

I would definitely do the PCM update since that will likely fix your P0089-64 fault

appreciate the response, do you mean do PCM through the dealer?
