Which one do you use and why?

 

MSD, simple easy, and allows you to either use ground or 12v to activate (which LPE does also). MSD and LPE seem to be the two most used, also the Harlan Two Step.

If you want to do a lot of different things go with the LPE with timing retard vs. map or psi, or get the one that has 3 limiter settings so you have a limiter on your footbrake and a limiter on your transbrake if you have one.

The LPE can also be used to cut ign. when shifting a manual tranny to allow wot upshifts.

 

Ok im not sure which to get, its a 6spd car for now. So other than a few different features i guess they are the same then?

 

The LPE has two different limiters in it? I really want to use one on the footbrake and one on the TB.

 

LPE lnc-003 has 2 limiters in it so you can use 1 for the foot brake and 1 for the Trans Brake. That is what I have

 

Thank you sir.

Synergy 2 step, because I have one for sale cheap

I also have one on my car and it works well.

 

I have an MSD and like it.

 

There are already a number of threads about this...

I've had both LPE and MSD. First bought the Lingenfelter; it stopped working after a couple months. The MSD came out around the time i was on the phone with Lingenfelter about the issue so i just bought the MSD to be done with it. The MSD has worked flawlessly.

 

The Lingefelter limiters seem really neat and intuitive when read about and looking at the spec sheets the timing retard functions, multiple limiters, and the torque cut for wot upshifts in manual tranny's is really neat.

I can't tell you how many threads I have read where someones LPE unit either stopped working shortly after installation, never worked right to begin with, or never worked at all. I don't think I have read one thread about the MSD unit messing up or not working suddenly. I've also heard from a couple N2O guys in the N2O section in threads where the retard function caused the motor to break up on the dyno, maybe due to interference by unsaudered or heat shrunk wires, but it caused frustration and that feature was not used anymore.

I wish MSD would step up in the LS department with stand alone limiters that allow using a second limiter for the footbrake on a turbo car along with one for the trans brake, and timing retard function vs. map/psi/time/rpm. I'm sure if they did one or several that had these functions they'd work just as good as the one you and I have. Until then, we are stuck with what we got, which in my case works great.

 

Im aware that there are other threads thanks....None had good info like this one does. Well after seeing this stuff I think im going towards the msd unit.

 

I was one of the people that had the Lingenfucker no step. It worked at first then stopped. Dont get me started on there customer service.
I bought two MSD two steps, runs them parralel in my turbo car so I use the first step on the foot brake and the second step on the trans brake. This setup is on its third season without an issue

 

i run the msd. incredibly easy to install and works great. i need to play with timing through hpt to see how much boost i can get out of it

 

How do you have them wired?

 

There is a mistake on this sketch, havent gotten around to repairing. The connections that are marked 87 should say 87A and the ones that say 87A should say 87. The diode is from radio shack it was nothing special.
When staging the car I do the burnout and then press the momentary button marked PB1. this enables both steps to be locked in, I get close to the beams stop and floor the car. The car goes on the first step and I footbrake untill both bulbs are lit. I then engage the transbrake, that releases the first step and it goes up to the launch RPM. When the transbrake is released it releases the second step.

 

I have a msd, a 4yr old could hook it up. I've know too many people who had a lingenfelter that stopped working or caused ignition problems in there car.

 

so as long as you use the clutch wire to activate the msd unit will help with shifting? (M6)

 

I have a Lingefelter LNC-002. I think the problem with them is that they aren't weather-proof. Looking at mine where the adjustments are made and also where the wires enter/exit the unit there just isn't any protection from the elements. I'm thinking about mounting mine inside my car somewhere when I make a custom harness.

 

I look at aircraft electrical schematics almost everyday but I am having a hard time with that one lol. I recognize the switches, grounds and diodes and I kn ow the numbers are relating to what looks like one 5 pin relay and 4(?) 4 pin relays? I need it explained some more please. Thanks in advance.
