AJPTurbo Meth Tune.

Subscribed, as AdvanceTrac is not wanting to cooperate with my vehicle either.  We should dedicate a thread to this very issue, as I understand it's effecting multiple people.

Curious though... as I know there are non-pp SHOs in the 11's... how they are getting around the traction control issue... even with it dumbed down...

I am wondering if a stiffer suspension setup would keep the car more level thus keeping the weight over the front tires....

By the time I buy new shocks and lowering springs, it would be the same price as coilovers....

Not sure which one is better...

Stiffer might help, least in the rear to keep it from fully squatting and unloading the nose?  From my reading one of our biggest issues is wheel hop.  Combat that is probably goal #1, I just do not know what causes it in our cars.  suspension design/flex, low profile tires, both?  Then it is about weight transfer and tires that can stay hooked (new wheels with DR's?)

Some way to "recalibrate" the ECU/TCU to get the car launching in full awd rather than it rolling in the rear on demand might help too?

Coilovers are definitely better IF the roads around you are NOT terrible.  We do get some pretty decent winters here in the DMV area, but normally the roads are not as bad as in say, Boston or Detroit.  Those conditions may exceed the available adjustability in the coilovers.

As far as ECU tuning, I believe the 13+ (FoMoCo can correct me on this) do go 100% RWD on hard launches, just long enough to get going, then back to normal FWD/AWD logic.

I reached out to Jason at PImods.com  and he informed me he is unaware of any way to alter the stability control system using IDS.

I don't know if that is because of potential legal implications, or a 'there's no way to do it', but, that's where I wound up with that avenue.

The various OBD gauges I've used say 90% and the OEM gauge agrees.

That would explain why Brad said the 13+ tend not to have traction issues off the line as bad...

Just a quick update... purely datapoints...

Livernois Motorsports Final Remote Alky Tune 0 - 90 mph = 8.7 seconds

AJPTurbo Work in Progress Remote Alky Tune  0 - 90 mph = 7.8 seconds (Assuming the wallace 1/8 mile calculator is right.. put me dangerously close to 11.9 in the 1/4... taken with a grain of salt as the internet lies.. according to Abraham Lincoln)

Neither of those were a brake boosted launch.. just an old man hitting the gas style..

It's a nice lie to live in

I think we should have a head to head showdown, meth vs E50

Every change he makes to yours (spark and boost) he makes to mine.

The last log I saw looked like we were about the same settings...15 psi and high 26 spark.

Your calculator data is pretty exciting.

The calc is from Wallace Racing, I don't take much stalk in it...

I agree!! E50 vs Meth would be a good one I think... although, curious how much your throttle is closing to keep fuel pressure?

That makes a big difference in volumetric efficiency thus more power... you can actually see the STFT going rich when the throttle closes with meth spraying...

I think the 2013+ handle E much better...

I dont think that's the case. you just have to tune to DI E85 strengths...which is scary to most because of its much different behavior when directly injected...It does not like being pig rich.

Look closely at my most recent log, pay close attention to lambse. We're not done yet but I am pleased with the changes. I think we've delayed enrichment further since I posted that one.

I'm still running a bit more spark than your meth tune....IAT compensations are back to stock, K&N heater is back on. The corn doesn't care it just does more work. It works better with hotter temps.

I just compared one of Tophers logs, he starts with 13 degrees lower ambient but by the end of the multi my IAT2 is actually a couple degrees cooler.

You mind emailing me your log? Unless it's posted here and I can't see it on Tapatalk...

interesting logs FoMoCoSHO.... your resolution is terrible, but might be all the DMR's you are logging...

I am thinking we should meet somewhere in the middle... between OHIO and VA... somewhere in PA with a 1/4 track to have a show down... it would be fun I think! Plus... I know there is a tuner that lives out that way.. maybe badger him into joining us.. lol...

Between you and I, he has probably developed close to 100 different tunes...

I don't do meth but I am anxious to see if that dude from PA can wake up my Continental!  Carry on, meth guys!!
