What launch controller for an LT1 m6 to use?

[djm_e22]

What launch controller do you use for your LT1 6 speed? Also how does wiring work on these things when used for a 6 speed?

If you have an msd box you can get an add on msd 2 step.

Or if you just buy the new msd 6al-2 it has it built in. Thats what I'm gonna do

I have the MSD digital 6+ with built in rev limiter, 2 step and timing retard easy to install, deciding where to put the button is the hardest part. lol

I put a microswitch on the bracket below the clutch pedal. The clutch has to be on the floor to activate it. Its also far enough down that the 2 step doesn't get activated on the upshifts. I run a msd 6 al with a 2 step.

dont some people use the two step during shifting and this is where the bang comes from when shifting?

was wondering this the other day for my car...

[AChotrod]

I dont want it to limit my shifts. So I put a button on the steering wheel for easy use and launch only.

i like the clutch switch idea with a steering wheel or shifter button so that once you leave the line and let go of the of the other button there is no way you will re-engage the 2 step on shifts basically to switches wired in series so both have to be closed for the 2 step to come on

[I_Need_Land]

again, i think some people DO use it while shifting, i believe srt4 guys do it so that when you shift it cuts the power of the engine and makes no lift shifting super easy, at the same time the 2 step keeps the turbo spooled...

anyone with insight on this?

[AChotrod]

Yes Ive seen guys do it, and shoot flames. I cant see cutting out the RPMs below your shift points good maybe easier but I think the delay and drop is too much. Especially if your a fast shifter.

Why couldn't I use my hyfire 6 ignition? It has a 2 stage rev limiter. I could use one as my launch controller and the other to protect my engine from reving to high. Also can using these launch controllers all the time cause problems?

I have my two step on a momentary switch.

and don't use it during shifts. if you feel the need to power shift (i.e. don't lift to shift, not letting off the gas), then do it right. If done fast enough, you shouldn't bounce your car off of your rev limiter between shifts, if you do, that means you need to practice on shifting faster.

What exactly does it do ?

[AChotrod]

Its a secondary rev limiter. I also use mine on the momentary button on the wheel. I hold it in push in the clutch and put the gas to the floor. Then it holds the rpms at what ever you set it at untill you let off the button. Dump the clutch with the gas to the floor and let off the button at the same time.
You should never hit the primary rev limitier as long as you dont miss shift or rev to high.
This is what it looks like hooked up to the clutch

So its basicly for racing to hold the exact rpm you want to come off the line with ? Thats pretty neat

[AChotrod]

yep! Sorry if the link didnt work

I leave at 6000-6800 depending on track so it really doesn't matter to me if it would enguage between shifts. But..if your carefull with the placement you shouldn't reach it between shifts. If on upshifts your clutch pedal is hitting the floor your loosing time. My clutch disenguages about 1/4 of clutch travel so I just jab it and let go.

[LT1]

I was thinking of buying the MSD 3 step for my MSD6AL box, is it better to get the 2 step instead?

If your leaving at 6800 then it would make no difference since your shift point is below launch point. I only leave around 4500-5k so, I dont think that would work for me untill I can hook the car leaving that high.. I shift just jabbing the clutch also maybe about a 1/4 after launching.

unless he/she is shifting above 6800?

you guys w/ 6-speeds are crazy....
