Hello everyone,

I recently stated that the racechip gts black was having troubles in Map 7. So i went back down to map 1 and every three days went up maps, then i tested map 6 for a week straight and it was perfect. No pull timing feeling, ran good numbers. So i figured hmm maybe it's used to it now tried map 7 again today, and instead of my car actually stopping at 127mph now it pauses at 115 and the entire acceleration feels jittery. So if you own a racechip map 7 is a gimmick. Not sure why but definitely does not work in that mode.

Youre gonna get the “i ran map 7 no problem” responses but thats only a few data points. It looks like your particular car/fuel combo doesnt like map 7. It happens but i think the 100-200 on map 6 vs map 7 was only a couple tenths slower and 60-130 a few tenths (when map 7 actually worked and didnt start chewing the motor). I would either stop messing with map 7 (if i couldnt keep it in my pants ��) or ask race chip to send a logger or a US replacement unit or mapping for 91 octane on map 7 (which will prob be equal to map 6 now so whats the point right?). You may also need to re gap your spark plugs which will help with a tune also. I suspect you would have the same issue with jb4 or even possibly a tune. Thats my 2c for what its worth (probably not much lol).

It goes a long way forsure, I'm going to contact them tomorrow and see what can happen. Also will check out those spark plugs out- map 6 is good but i was looking to be in the high 7 second 60-130 range honestly. Really wish there was a real tune out

60-130 in the 7s is crazy fast for a 6 banger. Just to put that into perspective that what my friends huracan does, as did my R8 v10 plus. Youre gonna need a tune for sure lol. I still think map 6 can safely do low 8s your DA was over 2000. For plug and play thats a really solid result.

Exactly 😂😂. Yeah i know though I'm impressed with the 1 second lost in the 60-130 as is. By the way i was wondering if you ran an o2 simulator with downpipes would that run well? So it doesn't have a CEL in theory

I always do 200 cell cats when i do headers. Im leaving stock headers on my m3 tho.

Have seen numerous under 8 second 100-200kph (62-124mph) runs on Youtube stock M3/4 Comp. Seem to recall 7.7 was the best. Other cars compared to it weren't even close--RS5, C63S AMG, Alpha Q, 911/911S. Very impressed with this part of power band as it's the most usable for road driving--conditions permitting, of course.

We are talking 60-130 tho. Usually add 1 sec or more

Why settle for race chip ? Wait for a proper tune when it is available, if you are already going to void the mechanical portion of your warranty.

Why not , it's advertised as safe and tune won't be out for another year atleast

Theres nothing wrong with doing both if you have the mod bug. Plus ive seen plenty of issues with flashes too. And stock.

They/you definitely need to log what's going on here. Thanks for putting in the effort to do this
