Default Harlan 2-Step is the ****

Right on Harlan, Thanks for a great product, keep up the good work! I got it in the mail on thursday, and was testing it on the street today. I tell you what, it just punishes the tires on the street. I can't wait to hit it on the track next weekend.

Harlan, seriously, its good to have someone who will go out and design something totaly new for a limited market. Thanks.

what would cause my 2-step not to release when I let my clutch out it engages right but when you dump clutch only runs up to what it is set at.

I wouldn't say this is a automatic car only thing. It will help people maintain the same launch RPMs on each and every launch. This helps tremendously tward improving your consistancy. Which is a must if you are a bracket racer. also it reduces the number of thigs you are doing at once on the line, hopefully helping your R/T.

You'll have to ask Harlan, with any specific questions...

Do you have an adjustable master?

Gray wire to the clutch switch, white to the arm switch? Right?

FWIW, i'm a 6 speed and i made it with that in mind.

If memory serves, the switch itself is adjustable. You can bring it closer to the tab on the pedal, make sure it closes when the pedal is released.

That's the first shot at finding the problem

Default Re: Harlan 2-Step is the ****

Anyone want to explain in simple terms what the hell this thing does <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I checked out their website and still cannot figure out what exactly this does and why I would want one.

Their website says "When the 2 step is enabled, an ignition cutoff rev-limiter is enabled"

I already have a rev-limiter in my standard PCM to protect against over revs - so this thing cuts off my ignition at some other rpms???

How does cutting off my ignition help with more consistent launches as stated on their website <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I'm thinking when this thing shuts off my ignition, I will consistently go NOWHERE <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" /> - LOL.

I'm sure there must be a logical explanation, but from what I've read, even on there website I can't figure out what this does or why I would possibly want one.

My initial impression is that this is some rpm controlled switch for use controlling Nitrous, but it isn't clear from what I have read...
Someone help me understand what the heck this thing does.

Default Re: Harlan 2-Step is the ****

My personal reasoning behind the 2 step was to build boost on the line w/ the turbos and a 6 speed.

Now the general reasoning...

You launch at the track at some given RPM. Normally the procedure is to stage, apply enough throttle to bring the rev's up to you launch point, and hold until the 2nd yellow. Then drop the clutch or release the brake.

If your like me, your RPM will vary each time. And you end up either watching the tree or the tach, but never both.

On the 2 step, you set the launch RPM and forget it. Just go to WOT on the line w/ the 2 step on and the engine speed is held at the set limit.

It's a race only device, does nothing for you day to day on the street.

It's not designed or intended to function as and over-rev limiter. It's simply a staging limiter. MSD and the others make them for normal single coil ignition systems, but we've got 8 coils and i wanted one. Thus the 2 step <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Matt...before I try mine out, just want to make sure all is OK.

I wired the white wire to the same wire that feeds the transbrake solenoid, so when the transbrake is engaged, so will the 2-step.

And I wired the gray wire to ground.

Is this right?

Thanks!

Harlan

Did you figure out a way to make the 2-step work on a 98? I have been use a switch, but doesn't work as well as it should.

Let me know, I really need to get this thing working right.

Thanks

David
