So according to the manual, in order to do a two step, i would have to hook up a 12v switch to the aux input. So does this mean that I would have to have some kind of switch turned on or button pushed in while im staging a launch, then after i release the clutch I would have to turn the switch off or release the button? Is there a way i can set it up so that when i launch the car the soft limiter turns off on its own? Or do I have to learn some finesse and deal with it. Maybe there is a way to deactivate the swithch when the tires are moving?

put the switch on the clutch pedel!

 

That would be great, but then your shift is affected. Lets say you put the stage to limit at 4k or 5k. Everytime you shift over that, it will cut the ig/fuel. creating a hickup. You will have hesitation at every shift(assuming you go over the limit).

 

I was thinking about hooking it up to the clutch pedel but I have the exact thoughts martin has.

 

think about it, for most boxes to shift properly they need the power taken away from them and most of the time you lift off the throttle, when your off the throttle it dosent matter what the limit is set to

 

I keep my feet on the accel all the way through. Therefore it affects me when I shift. Although since I have a big laggy turbo, I guess the clutch switch makes sense.

 

I thought that this "Antilag" was bad for our cars/motors???

 

Well I attempted to use this feature and i dont exactly see the point of it. It is a little misleading, unless its not working correctly. Now i set the inprevlim to 3500 and connected a 12v source to a button and then to the aux input wire. Now when i push the button in and give it gas, the revs still go over 3500 but when it does it feels like crap and backfires. I thought the point of this was to have a second rev limiter for launching the car so you can build boost or something. I was expecting the revs to not exceed the set point. I dont mind the back firing but but i dont want the revs to go over where i want them. Otherwise this isnt a real two step. Maybe i have this incorrect or something. Can anyone chime in and give me some feedback.

yea, you have to use the rev cut....

 

make sure you have your foot flat to the floor,

the revs should stop at 3500rpm

 

So It is only activated at WOT?

 

Look first you have to use the revcut feature and forget about the revlimit. Revlimit removes gas. REvcut cuts ign, therefore its accurate. Once you have it on, no matter waht, it will not go over your revcut setting...

 

Good Info provided 10sec rx!

 

Revlim removes gas, and revcut cuts ignition? I thought the revlim cut the secondaries, and then the revcut cut the primaries? Which is it?

 

revcut cuts ignition. If you use both of them you should see the difference. REvlim acts like the stock ecu and kinda tries to keep the rpms at w.e. you set it at, but revcut bounces as soon as it gets to the point.... The bounces occurs from activating and deactivating the ignition..

 

I like this two step feature.
Dale how well does it work?
Basically you have the switch on, launch then switch it off?

 

People use a clutch switch. That way its only activated when you have the clutch pressed. I use a rocker switch, since I only use it for starts( which I never use).

 

A little late, but just to chime in, from the Manual it states that RevCut, cut's all fuel (all injectors), not ignition, while revlim just cuts off a bank of injectors.

 

doesnt that result in a lean condition? from bouncing between fuel/no fuel at WOT?

 

I want to know this as well. According to the manual the 2-step feature uses fuel cut. Does it cut fuel one cylinder at a time?

Also, is there a possibilty to send the ecu back so Microtech can change it to ign cut?

 

Has anybody else done this recently. I want to try this, this weekend and need to know if its worth it? Or should i just buy a two step feature from MSD sense i already have the 6al.

 

any updates?

 

bump?

is there any way to cut inj or is it only for fuel?

would cutting the fuel while u set at WOT not lean out?

 

in the manual it says: "Connect a +12v switch to the Aux Input, and set a limit figure in the InpRPMlim screen and use the InpTiming screen to retard the timing slightly: when the button is pressed, the engine will be limited to this RPM figure, and the timing to retarded (to prevent detonation). Releasing the button will deactivate the rev limiter and return the timing to its normal value, allowing the engine to instantly produce full power. This way you can very easily use the Aux Input to set up a basic "two step"


Doesnt say you need to use the hard or soft cut rem limiter like everyone else says?

 

Also these are the input functions:

InpRPMlim: This function is a Rev limiter that works only when the +12v Aux Input is activated

InpAIRadd: Opens the cold air bypass valve (if fitted) by the amount specified in this screen whenever the Aux Input is activated

InpEnrich: Specifies the amount of additional fuel you wish to add to the mixture when the Aux Input is activated.

InpTiming: Allows for an adjustment to the timing curve when the Aux Input is activated.
