FiTech EFI system

If you record to the handheld you can only see the logged info if you download it to a spreadsheet. All the functions recorded by the second are there to look at. No guessing. Did you record any info to the handheld? Sorry if Im stating the obvious here

It needs to work if FiTech puts out and update.

I would try and hook the handheld to another computer and see what happens.
