Coupling flash tunes with JB4
Which tune is this? The blue graph has a huge torque spike .

And yes your right the torque is in NM for some reason idk but it’s easy to convert to lbs w some math however the hp is awhp and my tuner at the time didn’t have the best fans for the dyno at that specific moment so ik I’m making more horsepower when my car is outside so the hp Is a little id say underrated cause my quarter mile times suggest my engine is making more jam w the tune as I got 11.5 w dragy I promise I will post my drag slips or dragy once I get good tires
need a new set of R888’s or ps4 but since winter is coming and this car is my daily ima get them on Michelin winter pilot sports on soon but prior to that ima get the new sets on and do the slips/quarter mile timing so I get a better time and results aiming for 11.4 flat 😈93+ octane only, w the cpc adjusted for no speed limit and the tcu tune for crisp on point shifts, using motul for my transmission fluid, OEM caused issues w gear 1 shifting to gear 2 after like 45k of tuned driving, but it went away after I did a transmission flush and oil change for me even tho I got the car at 0km Ive been the only owner, the oem tranny fluid goes bad v quick if your tuned or jb4 as its taking a beating from the extra power, replace every 55k for optimal health
my tuner knows what’s good w these cars he was a master tech at Mercedes for a long long time he knows his ****, I was on a eurocharged tune prior from my current tune and I didn’t like it, too many burbles, bad economy, **** I had burbles even on reduced/eco a little excessive for me 😂 but I still have love for eurocharged don’t get it twisted they are better then amr or most of the generic brands but not my taste tbh I can post my dyno sheet from the eurocharged tune as well if y’all want let me know !

I wonder what type of numbers you can do once your car has the intercooler upgrade from Wagner, also dyno your car dude I wanna see the power your making w the stacking and how the power curve flows w the stacking, would love to see the bell curve and the dips and how the jb4 supplements on maps other then 0 w the tune !!!! Just watch out for knock and you should be good hopefullyLast edited by 19’43s; Sep 26, 2020 at 04:47 PM.
What happened to that thread? I see AMR liked a comment in here today, maybe they had it removed?

Lest anyone think I figured that out from the above quoted posts, no, I saw the original posts before they were deleted. A lot of us did. Enough that it's not going away simply because AMR tried to hide it.

I have never seen such fast shifts and such a hard 2nd gear pull... I'm rarely even hitting close to 20psi, but I do plan on only switching this on when someone wants the smoke

Using JB4 logs, once of my logs recorded a 3.2 0-60, not going to say that's completely accurate but mid 3s for 0-60 seems like what it's hitting consistently, need to dragy this up soon.
