Hey there its a noobie question and its my first time using tactrix cable and ecu flash but can anybody help step by step how to chancge my 2step its currently at 5.5rpm but cause i bought some hoosier drag radials for my evo everybody is telling me to raise it up to 6k cause ill bog with the tires if its to low if anybody pleas could help me ill really appreciated thanks

 

Open ecuflash and read your current ROM. Then scroll down to the section that is titled something like limits. In there you will find speed limited rev limiter and stationary rev limiter. The one you want to adjust is the stationary rev limiter.

 

Before i change my 2step or launch control in other words can i save my rom before i make any changes

 

YES, in fact you should always save your current rom before making any changes. In case you totally screw something up, you can always go back to the one you had before.

 

How do you save your rom ???? Sorry for all these noob questions just tired of asking my tuner to change things tired of asking

 

When you have Ecuflash open, top left corner, File, Save ROM As, Done.

 

And how do you change your 2step/launch control can you tell me step by step please thanks

 

its very easy, just open the ROM, you will see a big list appear on the left hand side on Ecuflash with a bunch of unchecked boxes. Scroll down to the "Limits" section and click the box that says "Stationary Rev Limit".

Another small box should appear, highlight the number thats already in there (5500) and change it to whatever you want.

Save the rom and flash it back to you car.

 

Thank you so much man .... What do you think i should set it at with mu hoosier drag radials ppl are sayin 6k cause 5.5k will bog what do you honestly suggest

 

I would say at least 6k. I have mine at 6250 with good results. You can try 6k and if you bog then just go back and make it higher.

 

There really isnt one tried and true RPM to set it to as there s so many variables such as the tires you are using, tire pressures, your turbo, track conditions etc. I dont drag race nor launch my car so I can't provide some feedback as to what works for me but what I can tell you is that the best way to figure it out is to try different RPMs and see what works best for you. Changing the value in Ecuflash literally takes 5 seconds so try a value and see what it does for you. Start low and work your way up.
