Changing tunerpro map readings?

Is there a way to make tunerpro display kpa instead of voltage??

Yeah, figure out how to do the conversion (IOW, what math is required) and put it in the ADS file. F4 gets you the ALDL dialog. Click "Edit definition" and go to "Sensor Data" to open that branch of the tree. Look on the right side. Use the Operation drop down to choose the right math, fill out the contant fields (or build a table), change the title (or just create a second Map entry that is in kpa like I did the *C and *F) and save the ADS.

The od file have 0.411765 (map 105/255 = 0.4117647).
Operation = multiply
Factor = 0.411765
Offset = 0.000000
Unit label = kpa
Range high = 255
Range low = 0

od file?? Do I have to creat a lookup file and use it?? I tried making a new lookup file and kept getting errors and tunerpro would shut down. Maybe a bug?? I'll work with those number though, thanx a million honken

no, no lookup. just enter the info exactly as honken says into a new ALDL Value.

The correct equation to convert a 1-bar MAP in ADC counts to KPa is:

KPa = (N * 0.369) + 10.415

The factor will be 0.369 as a multiply and the offset will be 10.415

Thank you rbob. I used the other numbers and it seemed to be right. I'll try those instead.

Re: Changing tunerpro map readings?

I don't understand what I am mulitplying by? My MAP is listed as like 12 - 15v under normal driving conditions is this correct. Am I goint to be replaing N with the voltage? I don't understand.
