Is there any value in changing the DV on cars which do NOT have a remapped ECU?
I would say yes, or check it at the very least. It could be knackered and you just don't know until you get a map and realize something is wrong.
How do you guys rate the BF? Tempted buy one as Revo is just so far away! Can you load the standard map back on at any time then the remap back on as much as you want?
When you get the BF the device copies your existing map and downloads it to Superchips via the web/pc and the new map then gets downloaded back onto the BF a short time later. Meaning the device only holds your new map. However your old map is stored at Superchips I believe and you can request this at your pleasure. It would mean doing the whole process again though and a bit of a ball ache.
The REVO select has the ability to do what you are asking with ease but its a bit more money.
