Has anyone tried out the MSD 2-Step box?

$220, easy install...and you're in business?

What did you think of it?

I'll be honest; I love to row the gears, rev-match down shifts/heel and toe a bit when pushing through corners but I'm an amature when it comes to launching, mostly because the kind of practice you need to put in to get good at it, puts a genuine beat-down on your clutch and drivetrain and I just don't care to spend my money replacing those parts.

Yep, this box feels like cheating but after getting my butt handed to me off the line by my bud's automatic LS1 GTO ( ), I think I can use the help! About 50% of my holeshots go up in smoke and/or wheelhop... not so good.

Any thoughts would be greatly appreciated!

Get upper and lower control arms to cure your wheel hop if you haven't already, drag tires otherwise a 2-step would be wasted money.

Once you get a drag setup, then you can work on launching @6000+ off the 2-step.

 

Thanks!

Unfortunately, a bit of reading reveals that the wheelhop is not typically solved this way... bushings, playing with the the pinion angle, spring relocation, etc... or just going to lower traction tires.

Yeah... 6000RPM side stepping of the clutch sounds like fun (in someone else's car!). Maybe some day I will look into the drag radial route. In the mean time, I need to stick with all-around good performing Summer/street tires.

I have recently found some videos on Youtube that shows that Bama/SCT offers a 2-step as built into their tune. I'm going to look into that befoe I buy anything.

Has anyone here had this built into their tune?

 

A 2 step isn't really going to help you with wheel hop or spinning your tires because it's not really traction control. It's sole purpose is to limit RPM's at the launch which allows you to consistently launch at the same RPM so you can dial in your reaction times and be consistent with them. But as far as blowing your tires off or wheel hop, once you launch, the 2 step isn't limiting anything...so you'll have those same issues.

 

Not sure what you're reading but new, especially the lower control arms, will cure wheel hop. Pinion angle has nothing to do with keeping the rear planted.

Unless you just want the bling factor, The cheap $100 ones work as well as 200+ dollar ones. The upper control arm isn't truly needed unles you're lowered and need to adjust the pinion angle.

That's not a real 2-step, all they're doing is setting your neutral rpm which cuts fuel, not spark, does it work? Yes, is it better than a 2-step that cuts spark? Not IMVHO.

 

When you load a new tune, adjust the neutral rev limiter, that will act as your 2 step.

 

There is a ton of info about launching and wheel hop as you, no doubt, have seen.

I suggest this being added to your car to help with the hop:

I've seen amazing Go Pro video of what is going on with the UCA during wheel hop. The other parts mentioned don't have the same dynamics, but could also be helpful if that doesn't cure it.

And, launch at ~3,500-4,000 RPM, not 6,000. Maybe try to slip the clutch a little, if necessary, to avoid going up in smoke.

Then, maybe, you won't be seeing your buddy's taillights so much!

 

the upper CA, relatively sticky tires and heavyweight wheels are the source of the wheelhop. Wheelhop is traction...almost.

I recommend going with another upper first. Want no noise? Roush. The LCAs sometimes do it on their own but, if you do the upper, you'll hit the major player in the game and take him down. I added lowers after the Roush and saw limited further improvement and more road noise.

And if you have cat converters on the car, you can't use a two step, you'll load them up and fry them.

The sweet spot for launching my BBP car on a slick is 4500 rpm. It doesn't 60 any faster above that.

 

I love my MSD 2-Step. I currently have mine set at 4200 rpm with t/c on because I am still on stock rubber. Depending on the street the launch can be perfect, or it will bog slightly and pick right back up.

 

Not only does it sound intimidating, it also fits nicely under the intake cover.

I love my two step, helps me launch the same everytime.
I am using the WOTBOX though, it's like 5 things in one for $200 and a simple install can't really beat it. All programmable via the USB cable in my glove compartment

The MSD 2 step works well though, just less feature rich and kind of reminds me of an octopus.


wotbox..

 

Yeah, we just picked these up and I plan to have a few of my guys test these out. Should be good.
