stage 1 map with 3 bar sensors - SRT Forums

julius717 · 04-26-2009, 07:14 PM

OK dont ask why but i want to run the stage 1 map but I have 3bar map/tip sensors how can i in advantage change it to run with the 3bars so i can drive my car around.?

im on stock 577cc injectors right now and the car is running wierd when i scaled the stage 2 map down for 577 injectors i just want to run on the stage 1 map for now till i get my setup finalzed and get my full tune done.

Re-scale the Speed Density for 3 BAR.

MAP Slope or something like that, can't remember off the top of my head, not looking at it right now... Open the stock cal and the stage 2 cal at the same time. Look at the speed density scalars, you will see what I'm talking about. MAP Slope for the stock 2 BAR is something like 48, and for 3 BAR it's something like 61.

I use the S1 base calibration in a 3 bar setup all the time. Works great! Better than S2 in many cases. You need to rescale everything for 3 bar.

how do you do that? i tried changing he scaller for the Stage 1 to the Stage 2 values and it tells me its more then the maximum allowed. ???

There's an option in Advantage 3 that will let you put it a value over what it thinks the maximum is. It's in the options menu somewhere.

nice! so now when i change it all i have to do is change the Scaler thats it? make everything the same as the stage 2?

Yes, match the speed density scalar to Stage 2 and you should be good to go. Really only the MAP slope and minimum MAP values change from what I can remember. Again, I'm at work, so going off memory here.

right on im loading it in right now thanks man! this will hold me over till i get my full tune

No problem, did you get it figured out?

Now that I'm home and looking at it...

Tools -> Options
Uncheck the box that says "Check Min/MAX value limits".

Go to the Speed Density Scalar, change the following to match:

MAP Sensor Slope = 61.85
Maximum MAP = 300
Minimum MAP = 6.8

Save it, flash it, and you're good to go for 3BAR.

yeah i did it but my car is an 05 so the stage 1 04 code throws the battery light and the car ran wierd.

im back on the stage 2 flash with it scaled for 577. my issue is it keeps dropping to 14.0 at cruzing. i know it fine i just wanna make sure its not somthing mechanical. i have all new o2 sensors so its not that.

Why aren't you using the 05 code then?
