What does it do and what is it for? I sorta have an idea. But want to know for sure.

 

2step is for more cosistant launches, so you dont have that as a variable anymore when you are drag racing....

it limits the rpm to a pre determined amount then swithes off one you are moving(via a switch or some sort)

 

Actually it's a 2 different rev limiters. I have it on my msd dig 7 ignition. The 1st rev limit is wired to a toggle switch, I can set it to hold me at a certain rpm for a launch. The second is just the cut off rev limit so I won't overrev I just have that set at 8500. But I like how I can launch w/the 1st limit I just sit there building my boost.

 

i got a question for you how is the digital 7 working for you i have a 6al with 2 step and i wanted to upgrade the ignition soo, im not sure weither i want to go 7al or digital

 

It's working great. It is really simple to use. I know w/the 7 al you have to do all kinds of programming and other stuff for it to work good. But if you upgrade to the dig 7+ you have to get a new 7 series coil. But it's a great ignition. And it's the size of the other 6 series ignitons, not all huge and bulky like the 7al.

 

ok thanks

 

hey, where did you get your 2 step for the 6al? did you get it through msd or did you make your own?

 

umm no i broke down and bought it from summitracing.com

it wasnt to expensive....

plus i have ordered some other stuff from summit and they are nice and reliable, not like the other import companies

 

newb question about msd ignitions... if i buy a msd 6al, do i need to get the external coil and distributor cap? or anything else? i checked out the msd website and the summitracing.com website and they didnt mention anything else but i always see more then just that box on other peoples' cars.

 

umm no you do not have too, but its not extremly expensive and not to hard to install so....you just make a choice

 

its better to . if your gonna get one thing , might as well get it all .
granted you dont really get power from the igniton , but your still gonna be held back by your stock coil and **** .
the cap is like30 and the coil is like 30.. just a couple extra bucks no biggie
i cant wait to finish up my installl , everything is done but my 2 step . i didnt gt a swx for it yet

 

i never dealt with anything ignition before... do you think its worth it upgrading from stock? im not going to need spark plug wires and all that other stuff am i?

 

well the msd does not like to run on the copper coil wires that are ngk, so you should change over to msd wires.....


as far asn the upgrade is concerned, it all depends on how much power you plan on making

 

i used my clutch switch to engadge it, so when its all the way down its on the first revlimit and when its out its on the second....

the way i have it run now is through the same switch but i have a toggle swith running in the circuit so that it can be sweitched off when im course raceing so when i heel toe downshift i dont hit 4000 rpm limit

 

That's what i thought.

 

what were the parts you ordered from summit to use this feature and did you need anything else from msd if i have the 6al already? i would appreciate a how to on setting this up (what wires to hook up, etc). thanks

 

the part number for the 2step is

MSD-8739

but you have to figure out where you are going to run the switch off of

 

i just upgraded everything at the same time . msd plug wires, dig 6, cap , blaster ss coil .

 

I dont think its nessary to upgrade ur ignition if you have numbers under 350 HP. IMO it might just be a waste of money...unless your all out speedracer.

 

i got mine for safety and the extra functions for the nitrous. .

 

thanks for the info. i'm planning to run it off of the clutch pedal as well. what part would i need for that?

 

yeah i have it run on the clutch switch, but the clutch switch is completely disconnected from the ecu, so i can start the car with the clutch out, yes just let yourself get used to it if you want to do it that way......

i knwo teres a way to get it done where you can use it that way, but my cars a race car so its no big deal for me and so far its worked out fine........

its just kind of a paint to crawl under the dash and get to that thing

 

is it possible to run the clutch switch without disconnecting th wire to the ecu?
