2-step question
 

i have a STS A4 been told a 2-step would help my 60 ft times. how does it work and do i need anything beyond the 2-step to make it work ????

Their are 2 types of 2 step hard cut and soft cut

Soft cut: just cuts the ignition at a certain rpm causing allowing the motor to load up.

Hard cut: Not only does it cut ignition but it retards it almost 180* out so that it fires out the exhaust stroke and uses all the energy to spool the turbo. (kills turbines and bearings)

I believe Synergy is the only one who has a 2 step for the stock pcm now, unless Harlan has his 2 step up and running again.

Here is an example of a hard cut 2 step on a supra

you can hear how long it takes to get the turbo spooling

which version was the Harlan, soft or hard?

his design was soft cut

He ever get back to you about your "harlan 2 step," Frank? I asked him to call you....

Nope, never got a call.

Hell Harlan, just send the broken one back. I work with a bunch of EE's. We can fix it :)

I absolutely loved that thing. Probably one of the best mods. :(

Man add another one to my "list" :lol:

Hope he at least sends the broken one back....

I was also interested in this.. It seems that is BAD for your motor and turbo?

I dont know about the motor, but I can see it being REALLY bad for the turbo...

How bad is the Soft Cut on the Turbo?

the soft cut is not bad at all

Sweet! I might need to look into getting one of those!

would you guys prefer the 2-step on my sts A4 or a 50 shot of nitrous ???? i have a 3000 stall very tight converter

i tried getting an answer in another thread about this how much will a hard cut 2 step shorten the bearing/turbo life?

I don't believe anyone make a hard-cut box for the ls1, you would need an AEM/XFI/BS3 to get a hard cut, as far as bearing life jose/dr. Turbo should be able to give you a more definite answer.

if i remember correctly he said they never noticed anything failing earlier

I would do a 2 step first and if you don't improve the way you want just add a 50 shot

Is there a 2 step for Manual guys?

:newbie:

I believe the 2-steps work on both, I don't think they are different for a manual car.

only how they are activated....on 99+ f bodys they wire to the clutch switch in the ecu in a 98 u either have to use a microswitch or a momentary.these are how they connect on a manual

but they dont make em anyway right?
