[Does anyone know anything about BTR Shift ramps?]

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.

[Does anyone know anything about BTR Shift ramps?]

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

How did you acheive full line pressure? 

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

[Does anyone know anything about BTR Shift ramps?]

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

[Does anyone know anything about BTR Shift ramps?]

Will do, thanks man✌️

[Does anyone know anything about BTR Shift ramps?]

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

[Does anyone know anything about BTR Shift ramps?]

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

[Does anyone have a stock BA Xr6t tune or strategy?]

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.

[Does anyone have a stock BA Xr6t tune or strategy?]

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

remembering a BTR will take a solid forever to change gears

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

Looking at the table from BeerTurbo, column 1 @ 100% throttle, you would multiply 2170 x 1st gear ratio which gives you the calculated engine RPM for the gearshift.

 

2170 x 2.39 = 5186rpm. Hope that helps.

Gear ratios are:

1st - 2.39:1
2nd - 1.45:1
3rd - 1.00:1
4th - 0.68:1

it does, thank you very much 

[4 Speed BTR Gear Changes]

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

is it 2.743 times xRPM ?

Looked at accelerator pump enrichment?

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

The values are a multiplication of gear ratio, not engine RPM. 3rd gear is 1:1 which matches engine RPM. Allow several hundred RPM for shift event to occur, especially in lower gears or an engine which revs quick. 

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 ☺️

[What would cause AFR to go lean at any throttle input?]

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

[1.25 Release Notes]

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

These cars do not have a fuel pressure sensor. You'll need to check it mechanically. 

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.

Did you set up the new map sensor with the correct slope and offset in the software?

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🤷‍♀️

[What would cause AFR to go lean at any throttle input?]

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

[What would cause AFR to go lean at any throttle input?]

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.

  

[What would cause AFR to go lean at any throttle input?]

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.

[What would cause AFR to go lean at any throttle input?]

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
