I am new to the kpro (although experienced with other systems.) I pulled down some datalogs and kal files from clubrsx (all of them turbo kal's.)

When I looked at the datalogs, specifically the MAP (PSI) paramater it looks scaled from 0 - 100 psi? Yet when I look at the display it is saying roughly 22 psi, but reads off the chart on the graph. Even more strange, the guy who's map I pulled said he was running 9 psi. Im sure its a setting or units configuration error on my end, but I cant seem to find it. Also, is the reading of 22 psi on the display while actual being 9, due to one of the atmospheric (14.7) radio buttons in settings/units?

Thanks in advance,
Mark

You will have to post the calibrations and datalogs in question.

The unit is in kPa by default. 100 being WOT at sea level. Generally speaking, when you tune part throttle and N/A WOT, you use kPa. 90 kPa is basically 900 millibar (millibar is what the load column headers in the table use). When You go into boost columns (make sure to enable show boost columns) the column headers switch from millibar to psi over atmosphere, ie, boost numbers. The columns go like so: .5 psi, 4 psi, 8 psi, 12 psi. There are 3 bar tables as well, but for 9psi, you will not need them.

So, in boost you are above 100kPa (above 1000 millibar) and are in the boost columns in the tables. In order to view the PSI over ATMOSPHERE number, ie the boost/vacuum psi number, you need to change the map sensor display setting in kmanager. What I do is open the sensor window, double click on map, then select the "/psi setting and set the maximum display to 2. Basically this means 2 bar if I remember correctly... meaning you will see 2 bars worth of pressure data, full vacuum to N/A wot and N/A wot to 14.7 psi of boost, a total of 2*14.7 psi of sensor data for the map in the graph. This way on the graph, the map line will be at the top near 14.7psi. It will be in the upper half under boost etc...

First off thanks for the help. About 98% of that I knew, but what you did help me with was the units configuration on the MAP parameter. Specifically setting it to "/PSI. Thats exactly where the error was. I had it set to standard PSI so it was whatever the boost level was + Atmospheric before I made the change. Thats kinda what I thought it was, but didn't know how to ariculate my question...

To your point about tuning NA regions of the map, I cant stand tuning with KPA. I learned on an AEM and did everything in PSI relative to absolute. Although it really doesn't matter (kpa vs PSI) I set mine up in Inches and "Absolute (Increases from full vacuum)" Its preference I know, but again thats how I learned.

Thanks again,
Mark

No problem -- had to cover some basics as many folks who come in here, including myself at one time in the past, don't really have any ems experience of any kind. The unit conversion for the sensor and display value thing took me a little tinkering before I figured it out with some boost datalogs. It's not one of the most obvious settings in kmanager.

Yep I totally know what you mean. I am really happy with how much easier the kpro is than other EMS' I've worked with. The hardest thing has been learning the idiosyncracies of the system (as it is with most) Just finding where shit is located if you know what I mean.

Thanks again...oh and:
