Vonlam43 Posted May 24, 2012 Share Posted May 24, 2012 I'm still pretty new to this website but it has helped me a lot but I'll get to the point. I'm curious if there is anyway to put a 2 step launch control on a 77 280z I have zx distributor swap if that makes any difference any help or input would be greatly appreciated.

luseboy Posted May 24, 2012 Share Posted May 24, 2012 Nothing's impossible. But seriously, why do that? That's gonna be so much work. I doubt you'd be able to do it with the L28. I'd imagine you'd need to swap in a motor that is drive by wire and currently has launch control. This means motor, trans, gas pedal, wiring harness, ECU. It's gonna end up costing so much and being such a pain that I honestly don't see the point. Unless there's some sort of universal launch control module out there, but I still don't see how it would be possible with a mechanically operated throttle body. I suppose you could find an electric throttle body that you could modify to fit, but then you'd need the computer along with it. Unless you're very handy with computer programming and that sort of thing, I would say it's beyond pretty much any car enthusiast's budget or skill set. And at the end of the day, you're driving a car from the 70's, why put launch control in it? I don't know about you, but the reason I bought a 240z is to get away from computers and all the crap going on in modern cars. I personally hate it, and I'm a young member of the generation that grew up with it. Maybe practicing your launches on a drag strip would be better money spent... Personally I'd take more pride in perfecting using my own two feet than programing a computer to do an overcomplicated form of cruise control.

Thats actually the whole reason I'm trying to find one so that I can pull good 60ft times at the drags I'm going to see how the old "Fair" will do just waiting to get my regrind cam back now.

An MSD "2-step" is a simple ignition system addition, used with an MSD ignition that allows an engine to rev to a certain RPM for consistant launches. I really have no idea where you got this idea about needing drive by wire throttle bodies and a different engine, etc. Quote Link to comment Share on other sites More sharing options...

johnc Posted May 24, 2012 Share Posted May 24, 2012 There are a number of different ways of doing launch control. Wheel speed sensors and software, engine rpm and software, dirveshaft speed and software, accelerometer and software... All require a good ECU, good software, and a lot of testing and tuning. What's funny is during the testing and tuning phase you'll learn how to better launch the car and thus reduce your need for launch control. Maybe you should just practice launchs?

I guess it was never anything I was really interested in doing so I never really looked into it. Disregard what I said... haha Quote Link to comment Share on other sites More sharing options...

So I couldn't just get like a 6AL with a 2 step module and wire it in? I'm running a zx dizzy in my 77' 280z if that matters at all. Quote Link to comment Share on other sites More sharing options...

Yes you can, people like to complicate things around here... The old school way was to use the 2-step module, and an MSD 6AL, there are newer ingition boxes though that have 2 steps built in, though they seem less reliable, than the older units. Unfortunatly the new 6AL doesn't allow for plug in limiter chips, and a different way would need to be employed, IIRC MSD used to have a limiter device that would get connected to bwteen the dizzy and the ignition box, intercepting the points trigger wire. Spend some time on the MSD (and other ignition manufacturers) websites, look for "2-step" or "multi-stage limiters", anything that will allow a high RPM limit and a low limit, usually activated by a switch.

Thank you for the input i've been trying to figure this out for a few days now and was going back and forth between the msd 6al and a Bee R Rev Limiter but couldn't decide.
