I am currently running titan motorsports protune and curious if anyone has logged AFR on the different maps? I understand stock is 14.6ish but am seeing anywhere from 12.9-14.6 at WOT given whatever map setting I am (downpipe plus bolt ons 93 vs 100 octane). Do the JB4 and Titan protune piggybacks change target AFR or is 14s still the target? Any JB4 users on e40 reporting richer AFR? I am trying to keep my car healthy and not use to seeing such high numbers lol. Any help would be appreciated!

I have the JB4 and notice that my AFR remains at about 14-15 but I see spikes to 25, it then settles back to 14-15

edit: I think itā€™s normalbetween shifts. I think fuel supply cuts off temporarily from each gear

Yes correct itā€™s normal to jump high between shifts or when you let off the gas. Are you on pump or a mix of e?

Not to hijack, but are you running the protune on a 21? Any idea what the power is like? I just installed it and seat of pants says map 3 is a solid improvement from stock, but I donā€™t know for sure the 21 is even mapped right.

This is on a 21 and I felt the same way lol. Iā€™ve been wanting to dyno. I was able to hit 11.9 at 121 but my stock tires spun bad (map 7). Seems like people get better gains on the 2020s and I was expecting a bigger improvement but was expecting more.
