93 octane helps a bunch, Run two tanks before coming to a conclusion.was hoping maybe someone in this forum could possibly chime in:
I've had my JB4 in for I'd say approximately two months with the only modifications to the car being lowering springs, BMS intake filter, JB4, and Corsa Centerline exhaust. I initially felt the JB4 didnt provide me with the results I wanted, but on occasion I would get extremely noticable performance improvements which would get my head out of the mud. However, my question lies more in "why is my power gain intermittent and what can I do to fix it?" I thought at first it was temperature (sunny florida) but I've experienced these issues on cold nights when the car feels like its 'sluggish' and was feeling a lot more energetic the previous day in similar environment. What I want to ask though is #1: Is this something I should expect from a piggy back? My experience with performance tunes has been strictly that of either dyno tuning or using a canned tune and #2 I have read about 'torque limiters' on this vehicle and I dont exactly understand how that works. Is the vehicle cutting power due to the torque being created by the supporting mods and tune, and/or is the low(er) tread my rear tires are starting to get to possibly inviting a loss of traction that the transmission reacts to by killing some power?
Sorry for the rant, its just bothersome when I take the car out looking for a little spirited driving and try to bang through the gears and I dont even feel my head go back into my seat once.
Any advice is awesome!
hmm, keep trying to post. Your IAT def is high. I just looked at my log from the past 2 weeks, I never get over 175.I did respond to peoples questions, thanks. And for some reason it's not posting the logs (saved in CSV files) and I'm currently looking on how to convert them. It's not bitching, its genuine concern for a possible underlying problem. I'm simply addressing a problem that I observed was listed in an alternative thread that never had a resolution posted and was hoping maybe someone had a first hand experience with a similar problem. Stating the IAT's are ridiculously high seems like a valid statement, as the logs show 258 temp at WOT. Going to post logs as soon as I can figure out how to properly attach them, as it said they were and obviously they did not.
I will double check my firmware, I purchased the jb4 approximately 3 ish months ago and it could be my user error that I assumed it was the most updated firmware.If you have the phone app you can graph it and screen shot it and post it
Also our IAT temp is post turbo but pre intercooler... But your number look odd. Do you have the newest jb4 firmware (I think IAT was rescaled at one point)
