intake exhaust and programmer...

[operator]

my best friend has a truck identical to mine only difference is color his is black I have a 2013 ram 1500 rcsb we both have 3:55 gears both 5.7 hemi I have a k&n intake flowmaster super 44 muffler swap and bully dog tuner he says someone showed him something called a second gear pre charge I turn tow haul on and turn off traction control I get him on the jump but he cantches up with me at 60 mph then walks away from me all he has is a flowmaster super 44 muffler on his truck stock intake and air fliter and no programmer can anyone help and tell me what im doing wrong. I should be blowing him out the water but he shouldn't be beating me.

What settings are you running on your BD? And what octane gas are you using?

He's using the second prime up-shift the first 4G Rams with 545RFE's used for drag racing.

Only on the 65RFE its called "3rd" gear now,
not in the normal upshift sequence , you engage it manually.

 

[BlackRamHemi]

545RFE:

1st 3.00:1
2nd 1.67:1
2nd Prime 1.50:1
3rd 1.00:1
4th 0.75:1
5th 0.67:1

2nd prime (now called 3rd in the new 6 speed)
is utilized only as a kick down (aka passing gear) in normal D mode

You can manually force it into the upshift sequence by holding the floor shifter left.

For me delayed my trans going into 3rd gear at the track by a second or so,
for higher MPH, and a quicker ET.

Here's what it looked like on my EVIC,
there is no 2nd prime designation, so it falsely reads 3, then when it shifts to 4 on the dash I'm actually in 3rd gear going through the traps (click pic for vid)



vid is about 4 years old, shortly after I bought the truck

Do you both have the same wheel size? Any tire upgrades?
Maybe he just has a stronger motor.; they do NOT all dyno equal.

I would play with the BD a bit, too. Raise your shift points, run premium tune with 93 octane gas and set your throttle sensitivity to the highest, etc.

Agree with this!! Shift point to 6000 should do it.

Agree with this!! Shift point to 6000 should do it.

I would not run your BD shift points at. 6000, that's red line and your risking motor damage.
Only go to 5850 maybe 5900 I know there's going to be those that say they red line at 6200 but trust me for the mods you have you don't want to be doing a lot of shifts at 6000.

 

[BlackRamHemi]

I've been shifting 1-2 at 6400 for over 3 years now, before boost, no issues

But a Bully Dog will never hit that high, only Diablo
(My BD would only hit 6000)

only Diablo can do 6200+

Maybe his "second gear precharge" is a bottle shot?

 

[UneasyJmitchell]

N2o.

 

[Statcher1]

Sounds like he's got a freak of a truck. Or he has alittle more done than he's telling you. Are you both 2wd or 4x4's?

^^^ I wish I had the faintest idea what that means... (feelin a lil dumb right now) Lol!

 

[Jerseymike]

So this thread motivated me to try a test. I launched my truck in 3rd gear and it shifted 1-2 at 6000 then 2-3 at 6000 then I manually shifted 3-4 at 6000. This is about the best I can do with the stupid column shifter. Nice. I am now wondering where it would have shifted 3-4 if I didnt shift it manually. Or where it would shift if I left it in first gear from the launch. I know a lot of guys are going to say redline but I dont know where the redline is set with the HF tune and my modifications to the HF tune??

Normally when I launch in drive it shifts 1-2 at 6000 then 2-4 at 5700 so the launch in 3rd was much better.

When I had the BD tuner it was set to shift at 6000 and would shift at 6000.

 

[DavidRam]

^^^ Hey, that's some really cool info. I gotta try it. How'd you come up with that idea??

 

[Jerseymike]

I saw a youtube video last year of a ram running the quarter mile and the truck shifting into 3rd, at first I thought there was something wrong. So back then I tried to manually shift 1-2-3-4 but the column shifter has a delay so it didnt work out to well. I have read of guys putting the truck in 5 or 6 to keep mds off and other guys leaving the truck in first and it will still shift on its own. So I tried 3rd and it works nicely. I have had this truck almost a year and I am still learning how to drive it.

so holding the shifter to the left will cause it to still shift on its own?

What settings are you running on your BD? And what octane gas are you using?

im on regular tune mds off shift points are at 5600 drive gear is 5800 tires size is stock 33s on 20 inch stock wheels both trucks

I would play with the BD a bit, too. Raise your shift points, run premium tune with 93 octane gas and set your throttle sensitivity to the highest, etc.

I ran 89 against him which is what I almost always use he runs 87 I run 93 every so often and I don't think I can set throttle sensitivity with BD

 

[BlownGP]

The shifting in these trucks really confuses me sometimes.lol
I can put it in first and it will shift by itself. Now if Im moving about 30-40mph and put it in manual mode. It wont shift by it self. It will stay in gear.

Then sometimes if I manually shift from a stop it will still shift when it wants.. haha

Now I dont think I've ever shifted manually under WOT, it's always been part throttle to 75%.. Wonder if that makes a difference?

It ****** me sometimes that I rarely want to use it. I think it has a lot to do with that 2nd prime.
