I setup my SF3/X3 tuner in my 2000 GT 5spd Convertible with a built in strategy flash for a 2500rpm neutral rev limit which gave me a sweet launch but...... Whilst driving my rev limit only goes to 2500rpm! Not so great! I checked my tune settings to make sure that the driving rev limit hadnt changed and it was set at 6500rpm so that was correct. I then reflashed the comp and still it limited to 2500rpm!
I gave up and flashed the neutral limit to 6500 to make the car drivable but i would really like the two step to work correctly.

Did I miss something in the setup? Is there something wrong with my car? (Clutch start inhibit works) MIght there be something wrong with the tuner?

The tuner has to go into the handheld and change one of the parameters to .5 instead of 1 for it to be enabled. Otherwise it just works as a one-step. I tried to do this same thing on my car, couldn't get it to work. I took my car to mph and he said it won't work at all on a 96-98 computer without an msd ignition setup.

If you're a manual your car will think you're in neutral all the time therefore limiting you all the time. Drive rev limit is for auto's.

That cant be right, what purpose would a two step serve for an auto transmission? The i thought whole purpose of the two step is for a manual car to set its launch rpm, bounce of the limiter and then dump the clutch when the tree lights up.

The first rev limit is set to zero speed, not for the car being in maual. It will work on a manual... thats the entire point.

I would do what the above poster said, check with your tuner to see if it needs enabled. I know alot of people have had trouble with the SCT xcal rev limiter for some reason.

Yeah i emailed SCT because i bought it from Latemodel restoration supply And it just came with the strategy tunes so i dont have a guy that tunes my tuner. SCT havent got back to me yet.
Could i check to see if is enabled?

That's not true. I called SCT and asked them. He said it WILL NOT WORK with a manual. I don't know about the other brands of tuners, or maybe if the livewire or Xcal3 has some new awesome way to do it, but the Xcal2= no 2 step for 5spd's. I blindly assume the newer models are the same.



I got mine and it did just as the OP described. I told my tuner what was going on, and he emailed me a tune that had the 2 step in it, and it did the same thing. So I just figured it didn't work with a 5spd, but EVERYONE says they think it will. So I just called them up. That's not the case.
