TOM Questions and General Upgrade
I know you guys are busy and probably get tons of questions...but I have a few if you don't mind. I have been thinking of purchasing a Fisker for a few years off and on and I got the bug again recently. I am currently looking at a few candidates. I have some questions regarding TOM and upgrades:
1) I understand the 520 is the better choice of software to use. How do I determine which software a potential car has? Assuming they are all updated, how easy is it to revert back? Is that a software change I can do or do I have to take it to a shop?
2) Where is PwrSource with respect to the battery upgrades?
3) Any other upgrades available regarding inverters and such.
4) Lastly, I found a very cheap Karma that is in fantastic condition with only 10K miles. However, it is showing a P0A27 and P0A29 code. Apparently, not drivable. Is this something that is potentially an easy fix or should I steer clear? If purchased, what price would you say is reasonable for this "problem" car?
I'm a fairly handy guy with respect to cars. I've done all my own work on my BMW i3. Purchasing a "project" is not a problem as I like to tinker. Assuming it's not a "Brick".
Thanks for any answers/ insight you may have.
