Works awesome extra hp makes launching hard without it lol

:thumb: That will for sure help Rob GJ man :thumb:

Geez Rob, had this laying around for a couple of years and kinda forgot about it. Now you got me thinking about it again.....damn you.:paddle:
.

I just installed a MSD 2-step in Pumpkin, but I used the Lingenfelter box to trigger it. Very cool piece and easy to adjust. Waited all winter to get it hot the press last month from Lingenfelter. :biggrin: As well I removed the AHR cat's by installing there cat delete pipes. Pumpkin is ready to rock with Ted's new cat delete tune.

:thumb:

I've had mine laying around for a couple of year too, until Lingenfelter came out with the new box. I did consider installing a micro switch like Robd, but once Lingenfelter came out with the box I quickly abandoned that idea for the CTAP-001 box.

Haha too funny thanks to visiting u at the drag strip I did my suspension ,rims and new rubber :paddle:call me if ya need any help with it

I have been waiting to do this mod. Is it plug and play or is it a little more complicated than that?

If you use the Lingenfelter box it is plug and play and pretty straight forward. However disconnecting the plug from the clutch position sensor to install the Lingefelter tap harness is not.:frown: The harness plug requires that you pull out a grey safety lock pin first and then use a pick to unlock a second lock. You also have to go cat delete or you will bang out the cat's from repeated use of the 2-step.

:thumbsup:

Glad to hear lingenfelter figured out how to make this install a little easier. I didn't realize I would have to do a cat delete though. I'm not sure I want to go that route.

Not sure how much you have to use it before you would bang the cat's out. I just got the cat delete sections from ARH. They were cheap and easy to change out and Pumpkin sounds great without them.

:thumbsup:

Epic Fail
 

Although we got Pumpkin to run the fastest time ever by 3/10's the MSD 2-step was an epic fail.:emoticon1::frusty: The first pass out of the box was a 13.00, what the f@#k.:frusty: Tried again same thing and Pumpkin just did not sound right by my friends observations. We tried putting the old tune back in, no difference.:frusty: So we disconnected the 2-step from the ignition system and Pumpkin instantly went back to a 12.40 car. Put the JRE tune back in and got after it and turned a 12.08.:happyanim:

Some how, some way the MSD 2-step screws with the ignition signal.:frusty:
I'm thinking that baby is headed to the river.:pound:

:thumb:

Thats all bad Merc. I'm curious now to see how Robs 2 Step behaves at the track.

Bryan

Planning on talking to MSD tech dept, maybe I got a bad one.

:thumb:

Talked with MSD this morning and they were no help.:frown: So I gave Jason at Lingenfelter a call about getting one of there daul stage 2-steps, but he wanted to try and solve the MSD 2-step first. Apparently routing of the wiring and placement of the box can be an issue as they my pick-up RF signals and partially trigger the 2-step. Got to take a bunch of photo's of wire routing and box placement to send off to Jason for a look see.

:thumb:

You auto or Manual?thought of putting one in my a6 but seems like everyone has better results off idle

Manual. 2-step will only work on a manual.

:thumb:

Mine seems to be working good used it a good ten times mines mounted on side of air box and wires are run behind front pulley from Side to side did you use the ground activation wire versus the positive activation wire wonder if that has anything to do with it acting up ? I used the ground one so I didn't have a hot wire running through firewall from clutch micro switch

I suspect I might have to move the box, which maybe too close to the plug wires. I used the ground activation as well. Have you run it down the track yet?

:thumb:

I am getting ready to install one of these has anyone got any pics of your home made micro switch bracket and where you are mounting it.

What are you setting it at? I was thinking between 2500 and 3000 rpm.

I generally launch Pumpkin around 4500. :D I'm going to use a Lingenfelter CTAP-01 box rather then a micro switch, much easier to adjust. Plan to start @ 95% setting on box, which would be 5% of clutch pedal travel off the the floor.

:thumbsup:

Are you running the stock differential
Is the clutch switch mounted at the top of your pedal or the bottom, I havent really looked under the dash yet

Yes and no. Stock with 3:91 gears and JRE caps and posi mod, LPW cover. Yes the clutch position sensor is in a very difficult spot at top of pedal bracket. :frown:

:thumbsup:

Well I was going to mount a micro switch somewhere at top of the pedal so it dose not release the 2 step till the pedal is all the way released
I guess I will have to fabricate something

I'd go with the Lingenfelter CTAP-01 box.

:thumbsup:

Might go that way after I look under the dash
After you calibrate the CTAP-01 box what settings do you use

I looked under the dash and ordered the Lingenfelter CTAP-01 box and the L480370108 plug and play harness I got a feeling that will save me a whole hell of a lot of aggravation

Thanks for getting me to look

Couple of tips:

Remove drivers seat for easier access.

To unplug the harness plug from clutch position sensor switch you must first remove a grey clip and then use a small pick to unlock second lock. It's pretty much blind and a total beach.:frusty: Practice on the brake switch harness first it's the same and a lot easier to get at.

:thumb:

Question Merc. Could you use the brake harness and pedal to activate the CTAP-001 box on an A6. The idea being to hold say 1400rpm (or whatever rpm as long as it didn't push the car) and activate the 2 Step when the brake pedal lifted 5%?

I always hold rpm's against the brake pedal when I'm staged but when watching the tree I know I'm not holding consistant rpm's every pass.
:iono:

Not sure. I'll be talking to Jason from Lingenfelter probably tomorrow I'll ask. He is thinking I have RF interference. Sent him pic's, He talking moving the MSD module farther away from motor and putting stock wires back on.

:thumb:

Sure would appreciate you asking for me. Thanks.

Bryan

I would think you could put a manual switch in there and tie it into a line lock and the 2 step Pump the brakes up to hold it and release the button to launch it

Yes that would work for sure. Thought of trying that myself. Both the linelock and 2-step can be activated at the same time on one button through ground.

:thumbsup:

Not sure of what settings
 

I'm not sure of what settings to use on the Lingenfelter CTAP-01 box I would like it to release the 2 step close to the top of the clutch pedal any one have a idea what settings on the Lingenfelter CTAP-01 box to use ?

Also I installed the 2 step that was a piece of cake, but the harness plug on top of the clutch appears to be a real pain to get to, was hot out so I abandoned that for now .
Will probably attempt it again by the weekend. I had a clutch issue about 6 months ago and they put the ZL1 pedal assembly in mine don't think the brackets are much different, from what I was told its more of a clutch master difference
