shift ramps under transmission pressure. its 50/50 on results. firmer shifts but hanging gears/not changing up and weird sh*t happening. I'm still experimenting and trying to dial it in.

I know you can in the E series but I haven't heard anything good or bad on the BA-BF. never tried it though

on auF1512 changing a lot of the table to -500 globally increases line pressure buy not bleeding off as much pressure. you'll either love it or hate it, but its the quick and easy method

Took your advice puffwaggen and turned out great, I'm kicking myself for not trying sooner, Cheers!

Will do, thanks man✌️

IP? alright so high pressure is self explanatory then, what does low pressure area do? i doubt it’s for downshifts as they’re their own parameters cheers

I was wondering if anyone knows whats what with the BTR Shift ramps? I am aware of the S5 temperature correction table but want to know more about shift ramps, if its possible for it to crank the pressure when its at say half throttle or in sports mode. I believe table B is an offset of A and table B is sports/towing mode. full line pressure all the time on a daily is just annoying to have, chirping tires in a 50 zone is just stupid if im not trying to thrash it. If anyone can shed some info on it, ill pay for the time for you to walk me though it

I'd love a copy too, especially for the VCM2

A mate linked me to a site full of strategy's and catchcodes, and I am aware of the S5 mod. next on the list is find out what shift ramps even are, if I can dial in the box to firm up on boost that would be mint.

I’m chasing a stock xr6t tune for the btr maps and parameters to add to my current ecu, as i will be putting a turbo box in the na+t setup being a newly built box I want to do it properly with wearing it in I can work with just a catch code too, thanks in advance

I've got a shift kit on mine and doesn't wait around to change gears lol

it does, thank you very much

stupid question, say if first gear is 2.743 to one, how do i calculate it out? is it 2.743 times xRPM ?

makes no difference. i’ve even entered stupid numbers in it in hope it made a difference, and nothing.

hey mate sorry to bring up an old post, but how is the multiplication worked out? what is it multiplied by and with what? Thanks in advance ☺️

yes I'm reviving an old topic, Its been on the dyno, made 263kw and 795nm torque, its been tuned well, but even he couldn't get rid of the lean spot. is there something we are missing? it has a Turbosmart rising rate fuel reg, with gauge, and no drop in fuel pressure, and I threw in a new filter just because, didn't make a difference

I don't mean to be rude either, but I am wondering too...

I'll look into fuel pressure for sure. prob wont be the worst idea to do a fuel filter while at it, Golebys do a fuel reg + gauge kit thankfully. The MAF and MAP parameters that I've changed, am I in the ballpark? Thanks.

I've merged a BF XR6T MAF Map auF0045/6 & Speed density auF0060 auF0053 & auF0057 I've merged FG XR6T Speed density scalars to mine, such as auF0512, auF0511 and left the rest alone due to being the same values. Data-logging shows fuel pressure at 3.90, I'd imagine that's fine if using a 4 bar reg. Plugs are just over a year old, but you never know I suppose🤷‍♀️

it’s only ever started doing this since i’ve put the FG xr6t MAP sensor in and the injectors + reg

when it was NA the O2 sensor was cooked and ran rich all the time, only noticed the 0v output of the cooked one about 2 months ago. i’ve got a wideband bunged into the down pipe not wired into the ecu monitoring everything, and an OBD2 HUD showing me trims. idle in gear, stft is 0-1.5% ltft 0% cruising -10 to -15% stft -3.1 LTFT unplugged the O2 sensor, 11-12afr cruising, 15.8afr in gear idle, does spike lean for a split second then immediately goes rich.

brand new pre cat O2 sensor on the dump as the new one was cooked, unsure what the LTFT is at will report back on that, as reflashed this morning, dealing with a ETC fault at the moment 🤦‍♀️ i never got data when i bought the injectors, been dialling them in for a while. stft is pretty good, WOT on open loop is almost dead on compared to commanded lambda. i’m not a tuner and this is my first ever car to go this in depth with. barrage tuning had a play with the injectors also.

BF XR6 NA with a turbo on it, nearly stalls from leaning out from any throttle input (I've had outright stall twice) slight increase in throttle in idle or cruising does the same thing. tiniest amount of throttle or 'boot it' will have the same results. STFT in gear is within 5%. If I re-flash the PCM, It will be fine, but it will start to appear after a day or two and gets worse from there. Once it goes lean the computer riches up the AFR after about 0.5-1 second and its good from there. its worst at stop start driving. stock xr6t exhaust cat back, 100cell cat, bosch 540 pump, FG Turbo MAP sensor, bosch 0 280 158 040 injectors '1150cc' @ 4 bar, stock xr6t crossover and piping, 105lb valve springs, stock motor from there Any info would be appreciated, thanks
