Na,  the brakes are bad enough (not sufficient) so I am not comfortable with that idea.  Brad will see what he can do.  And we will see where we get with him coding around it.

If all else fails then I will roll back to the last meth tune that did not have the issue and call it good.  I liked the power of rev3, in a dragrace rev3 made some easy kills out in PIR..  but as soon as we went rev3 the tq errors came on strong and make daily driving very much un-enjoyable.

finger crossed,  Brad has been amazing,  and has tunes on stronger rigs so i am very hopeful.

added a new log... check out timestamp 359+ .. it is slow roll into a farm road in 1st gear.  i floor it and it does some super sketchy power management.  it stop all power *hard* and a little scary then goes nutz
Hopefully no one looks through my download history and sees i downloaded a file with the words "big, log, and tranny"  LOL!!

Oh I have soooo much fun in restaurants with this topic when the gang hangs out::
"Yeah I banged the tranny real hard .. started slipping so i changed out the lube .."
"I should have been doing meth YEARS ago. Im going back to the dealer right after lunch!"
"I ran that b*tch HARD when she got tired i feed her more meth and got back on it .."

The looks I get .. priceless ..

Just pull out the abs fuse and call it a day lol

SBS and I spoke briefly about this when trying to fight our TQ15 demons, I believe before he was alky injected.

For science, I gave it a go, and yeah it works 100% on my 2012 nonPP.  Instrument cluster lights up like a Christmas tree and the DIC freaks out telling me all the errors, but Advancetrak is beaten.

I don't condone this as a full time solution, but if you want 0 intervention from Advancetrak for say, track use, I'd say give it a shot.

Yea, does your rear wheels still get power? Which fuse was it?

Yes my rear wheels still had power.  It is the #9 ABS Pump fuse in the box near the battery. 

The only immediate downside was all the indicator lights and warnings.  Still had all normal drivability, with the obvious lack of any ABS function whatsoever.

Nothing a little electrical tape can't hide!

I have rolled back to rev22 (meth rev2) and am retesting.  I am waiting to hear back from Brad who is hideously (and understandably) busy.

I may propose we start making much smaller edits to this tune versus the large jump we made in rev23 (meth rev3)

That's crazy yours is failing I've ran 100% meth before with no issues ran it for over a year now. They do state that it's possible to run 100 % meth but they highly don't recommend it I wish alky was cheaper but you gotta pay to play right! Hope all goes well man!

turns out is is a issue with fueling/tune and the plastic lines.  I was not getting proper fuel enrichment at specific conditions.  we have tuned past that.  now i am getting some power variations but i am pretty convinced its the shitty plastic lines from SNOW.

sigh... I will need to replace the lines with braided steel,  and replace the pump for 4an connectors .. about 70% the kit cost.  my fault for not doing enough research and buying a noT buying A polskifacet KIT ;)

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

I have decided to turn off the meth for now.  It is too cold and I am wondering if the issue is the meth not vaporizing..  at 375ml maybe I am getting wet in the cylinder but not enough to misfire.  Weather in Oregon is moist as hell and cold so I am betting the meth is wasted a bunch as is .. bummed out.

It should be noted the lines and fittings from Snow are inevitable for a catastrophic event,failures waiting to happen.  Z

Yeah we are now in prime boost lovers weather for the next many months.  Challenge is traction is limited now, but makes AWD just that much more fun and a big reason why I bought the SHO!!  I was noticing Sat on the way home from the range that I was cruising on the freeway @ 77* IAT2  Even sitting idling at a the 3rd light in 1/4mile I was just reaching 100*.  I will not have the other benefits you have with Meth, but totally feel the change in performance from the cold air.

Air gets denser which helps for sure! Requires more fuel though for the same reasons... I suspect as usual we will start seeing posts about hesitations under WOT popping up here soon...

Meth in the winter helps offset that...
