Just received and installed my JB4. Wow, what a difference. I thought that it would be more of a small felt power bump and pleasantly surprised at how much it changed. Had a couple questions regarding map choice. First, my car is a stock PP AB and plan on doing no serious mods as it is leased. Second, I run 93 always and have been E30 for the past 5K with no issues. I did not order the BMS cable when I ordered the unit. I take it that is needed to make any changes and Map 1 is default (duh). I would like to know if I should/can run Map 2 without any other changes. I got a CEL on the third WOT adaption run which turned out to be low fueling @ around 5K RPM. Cleared through VCDS and has not come back. It makes sense as it has been hot as balls recently with about a million percent humidity. I think the ECU was trying to fuel dump because of the high IAT and EGTs and simply ran out of fuel or that E30 caused a lean issue. Most times it would pop a CEL off idle and under a 30-40% load, so not worried about the eToH. I would like to run Map 6 after I learn more and have the chance to run some logs. It obviously won't make much sense to do alot when it heatsoaks as soon as I start driving. This drives my Map 2 question, safe to run without anything else? I know it may be blind advice without logging, but just need some direction. Sorry for the newb q's, I have read quite a bit so far and have a steep learning curve. TIA.
