2-step kills turbo? ( whats best to build boost off the line?)
Alright I was looking into getting the msd 6al along with the 2 step setup( cuts spark), because I had heard if I use the launch control through uberdata(cuts fuel) while im building boost that it will cause a lean situation. But then I heard that if I use the msd 2 step that its going to kill the turbo from all the little explosions going on. So the question is , what would be the best to use?

i have also heard it will pre maturely fail the turbo, i was told it would cause the shaft to get pushed real hard and wear out the bearing a little faster.
im sure its no big deal for a racecar, because thats part of racing, replacing stuff. but for us average dudes, it would probably get expensive.
i preload, and 2 step it, so far my turbo had 12,000 miles on it and half of those were races. still no problems yet

Re: (Laserjock)
By using the launch control in the ECU, it does not create a lean situation. How can a cylinder run lean if there is no fuel at all being injected? It can't. Anyways, there really isn't any other way to build boost with a manual tranny other than a spark cut. With launch control in Crome, I can make maybe 2-3 lbs of boost.

Re: 2-step kills turbo? (boostinhatch)
unless you have a realy good set of slicks you dont want boost off the line. I boost moderately in 1st and 2nd and third is where I crank the boost. concentrate on traction in 1st - 2nd and third to fourth is where it will pay off.
building boost off the line and burning your clutch or spinning tires (youre gonna be doing one or the other, possibly both) isnt the right approach.
You want to launch at tractions breaking point a little slip is ok but 100% hookup and keeping traction at the limit through 2nd is the key. then you can pour on everything you have once your in third and make your money.
Launch control isnt a bad idea if you cant get you launch consistent.

Re: 2-step kills turbo? (Syner-G-Racing)
Fuel cut and spark cut is not the same as 2 step. Crome and Uberdata, don't offer this option.
2 step is when the ignition gets retarded some much that the spark ignities when the exhasut valve opens so the flame front and non-technically speaking the "explosion" happens in the manifold/turbo. This spools up the turbo upon take off.
But like Syner-G-Racing you don't want that unless you have slicks or AWD cause you'll just spin out

Re: 2-step kills turbo? (adseguy)
well I have a nice set of slicks, so I defintly want to build boost off the line. I think im going to risk using the msd 2step method. Anyone else have any reasonable input as to which would be best?

Re: 2-step kills turbo? (boostinhatch)
i use the aem ems 2 step and I decide how much boost I want to run off the line. you need to get a 2 step that retards timing not cut fuel. the more fuel you have while using the 2 step is the more boost your going to make. Launching off the line at 15psi is fun

YES IT DOES CREAT A LEAN SITUATION. call hondata, youre right it doesnt cut all the fuel, just some of it, that how the damn car is still running!!!!!!!!!!!!! but it does cut some and doesnt pull ANY timing, this is a problem, especially when youre MAKING BOOST, sitting at a standstill, its a recipe for disaster, if not using the right 2 step set up, i have hondata, and went and purchased MSD just so i could 2 step properly.
listen to a hondata, crome, uberdata 2 step, it is super slow and sounds like ***. then listen to a 6aL or a digital 7 2 step, totally different systems

Re: (mrbsponge)
I don't need to call Hondata, I understand how this system works. It cuts fuel alternately to each injector, so each cylinder that is being cut has ZERO fuel being injected. Zero fuel = no lean condition in that particular cylinder. Look at a wideband 02 while FTL is active.
No **** they are obvously different, I never said they weren't. I even said that there is no other way to build real boost other than an MSD spark cut type of 2 step. Reading comprehention is key.

Re: (nfn15037)
I'd definintly be interested in knowing for sure whether the fuel cut launch control causes a lean situation. It worked great for me using slicks at the track last time. I was able to build 6psi off the line with my tiny turbo. I'm afraid to use it though because I dont' know if i'm hurting my motor.

Re: (SOHC_MShue)
Look at a wideband when FTL is active is all I can say. If you cut all of the fuel to an individual cylinder, there is no lean condition because there is no fuel to burn at all!

Re: (nfn15037)
my plx says "lean" then "air" i think this is what he is referring to when it says air it means NO fuel but i hardly believe this is the case. are there no hondata reps in here to clear this up?
