Driving an F10 and have been reading up on the ECU Tunes out there. Looks like the top 2 are JB4 and TMC. Read that JB4 have a couple of maps including a stock map which you can switch back to anytime, and I thought is great. Then I also read some great reviews on the TMC tune, but does it have different maps or just one tuning map. Which one is more stable, I heard that piggybacks can cause CELs and need a host of related mods to get it going? Can I plug a piggyback on without no mods at all. I am terribly divided on choice now. Which one should I also for.
Any advices will be highly appreciated.
