2014 SHO livernois 3 bar tune/tstat/downpipes

[ajpturbo]

It may depend on the dyno I dunno.....The particular model dynojet that I and Kyle were on was able to have the rollers linked mechanically. Apparently the belt and shaft are really heavy. I tried a run in 4th but ended up doing my runs in 3rd gear. I was not comfortable with the length of time the 4th gear pull took and 5th would've been out of the question.

My 4th gear pull took 17 seconds of WOT and my 3rd gear pull took 10 seconds..I think when you mechanically link the rollers then essentially one roller is dead weight in addition to the belt.

I've done pulls in 5th gear in my civic and mustang with less power and ripped through it in 5th gear...In the SHO on this dyno I couldn't believe how slow it pulled through the gear. Like I was towing something and doing WOT pulls.

Kyle, I have no idea what the software looks like for LMS but since they claim they can do things that other software can't do I'm guessing this will be easy for them...I don't mind helping the community even though this is proprietary information I'm about to give out that I've given a few popular tuners out there. So this is an AJP special freebie.

You need to set "pedal position to command kickdown in SST mode" to 1024

It's in the trans or trans shifting section, I can't remember

That's in SCT software. You will have to ask LMS if there is any such scalar, I don't know

It's not the RPM that caused it to downshift on you....When you nail the throttle in sport mode the throttle counts go up. Stock for that scalar is set to about 500 and when you exceed that it will command a downshift....When you set it to what I said, you effectively never hit the throttle counts  to command a downshift...If you were at 2000 rpm and roll on the throttle sometimes that keeps throttle counts low enough to not downshift.

But you have to be in SST not just S mode....So select S mode then tap a paddle to get it in manual mode...That's sst mode...If you change the scalar to what I said but only put it in S mode and floor it, it will still downshift

I love having it this way because when I go manual I can floor it and really feel the low end and midrange without getting a balls to the walls redline downshift

Thanks for the info, I'll have to ask LMS if they are able to do this.

SHO's have a really tall final drive and huge overall tire size. Matched up with the AWD turning two drums I can see that taking a bit.  As long as you get enough load/sample time that's all that matters.  Wonder what gear Torrie and LMS use for their stuff. 

 

[ajpturbo]

Yeah maybe relatively tall final drive but the transmission makes up for that and the large tires. Because looking at my log I hit 90mph in 3rd gear at redline and 114mph in 4th so pretty normal...I have a PP btw

Kyle's had to seem like an eternity with his NON PP

Honestly i dont feel like it took that long but this was my first time on the dyno so didnt know what to compare it to. Also he only did 3rd gear pulls, no 4th or 5th.

Here is the 2nd pull i believe

! No longer available

I do have another pull that was much faster then that one, more like 10-12 seconds.

 

[ajpturbo]

Well I'm going to guess since you are non PP you get close to 100mph in 3rd maybe more....So I'm guessing your pull was maybe at least 12 seconds....I can tell by how slow the tach swept through 3rd that there was a tremendous load on the car....More than the car's own weight....The tach moved much slower than when driving the car

So wouldn't be comfortable doing close to 20 second WOT pulls while what seemed to be comparable to towing something..

I see videos of FWD and RWD cars do pulls that last less than 8 seconds on the dyno.

 

[Vortech347]

Never thought of total time till you mentioned it.  Looked at the last video of dynoing my fox (1:1 4th), 1500rpm to 6200 took about 7 seconds.  Its got to be that AWD hammering the huge rollers. 

 

[ajpturbo]

Kyle it looked like ur pull was just about 10 seconds and that was from 3500 to 6400 or so...thats pretty long if u ask me

 

[kyle04]

What sort of problems could that cause and was there anything I could have done differently?

 

[ajpturbo]

Nothing...im just saying i think on that dyno if u did  4th or 5th gear pulls that could be a little tough on the car at your boost levels...based on my logs of the dyno and street wot pulls i think the pulls on that dyno would be like doing wot while towing somthing which i would never do lol

Ive never seen the tach move so slowly like it did on that dyno

 

[kyle04]

I see your signature says you're running 18-20 pounds of boost. Im guessing thats mostly where you're gaining that 40hp on me?

 

[ajpturbo]

Possibly...i have catless dp's also...i actually did a bone stock pull as far as boost and pit down 350/350..which seemed high to me but my "tuned" pulls seemed to be in line i had a max of 394hp/465 tq...but having other problems...if i could ever sort things out i could imagine 410-420 hp with 500 tq without meth

 

[kyle04]

I think the highest im ever seeing on the torque app for boost is around 13-14 pounds.

Over 400awhp would be awesome for non meth
