vgi,

Is there a way you can change the CL/OL Status Value for cobb to CL: on OL: off? The Cl/OL status values for cobb is no longer CL: 0 OL: 1. Thanks.

I'll take a look when I get time. Do you think someone might still be using older version with 0 and 1?

Can we update the throttle map tab to use only two of the three required tables?

On older roms (like my LGT A2WC522N) there are only two 3D tables:

Requested torque (pedal angle versus engine speed)

Target throttle Plate position (requested torque vs engine speed)

I may also just be misunderstanding how that tab works.

Thanks.

@welaish do you want to chime in? :)

I think I will leave then 0 and 1 but also add code to be able process 'on'/'off' values in the log file. I'll take a look.

@BURNING4ORCE pls pm me your log file.

Another vote for using only the two tables on the DBW tab.

I emailed you a log file link VGI. I also still use 0 and 1 and if you add a code to be able to process on/off values that would be awesome. Thanks for your time.

I dont think you need that for 2 tables its straight forward. the 2007+ there is a third table to in the calculation so to figure out the accelerator pedal position Vs the Throttle plate is quite diffecult hence the solution provided by VGI.

rhino6303, you can fill that 3rd table with something like that:
Code:
600 1
1000 1
3000 1
5000 1
7000 1

I added code to process new Cobb on/off Cl/OL status and cut a new release.

Thank you very much for this great tool vgi. I've done a fair bit of self tuning but always stock intakes, wasn't looking forward to rescaling MAF for CAI but this made it so much easier compared to messing around with spreadsheets. Cheers

Overall a very nice piece of work. Just a few issues with the Throttle tables and incorrect values I'm getting.
EG. RPM 1600, accel pedal % 17.5, Req Torque is 117.7812, RT Base (RPM) is 245.1.
The TP versus Accel output returns the incorrect value as 14.4774. Should be 11.9 in this example.

The Calc needs to be RQ Value / RT Base (RPM).
For my example, the RQ Accel table at 1600 rpm is 117.7812. Divide this by 245.1 from the RPM Base to get 0.4805. Look up Target Throttle plate position for 0.480 and 1600 RPM to get the throttle plate opening value. For me this it results in a TP opening of approx 11.9, not the incorrect value of 14.4774.

Also the whole 800 RPM row has very low TP values returned. TP opening is 1.76 at 98 accel. For me this should be nearly 100% TP.

From greater than 21 Accel pedal the TP opening angles are returning max values for most RPMs. Again this is probably a misalignment reference to the RT Base (RPM) table. The TP opening for me is more gradual and doesn't call for full TP until 65 % accel and above as per Airboys Throttle tables Tab spread sheet.

RT Base at 800 RPM (First column) does not show decimals. Would be good if you could allow manual entry into each input table values and then recalc on new values. Then we could copy back into Romraider.

Hi, the calculations are described in usage tab. I cant figure out what you mean from your 'exempli gratia' unless I see the tables you have (particularly all 3 tables axis and values) and confirm the calculations. When you click on cell in "Requested Torque - Accelerator Pedal" which is the base table you will see all axis cells and value cells which were used in calculations. Also, when you write "Look up Target Throttle plate position for 0.480 and 1600 RPM to get the throttle plate opening value. For me this it results in a TP opening of approx 11.9, not the incorrect value of 14.4774" you're not actually saying how you do the "Look up". I use this 2D bilinear interpolation formula for value calculation (because most of the time the value to look up X-axis from "Target Throttle Plate Position" will not be I direct match, and sometimes the RPM (Y-axis) value may not be a direct match):
/**
* Method returns a value interpolated from 2D grid
* (3D RomRaider tables) using bilinear interpolation
* @param x is X value you want to interpolate at
* @param y is Y value you want to interpolate at
* @param x0 is nearest x-axis value less than X
* @param x1 is nearest x-axis value greater than X
* @param y0 is nearest y-axis value less than Y
* @param y1 is nearest y-axis value greater than Y
* @param x0y0 is the table value at x0 and y0
* @param x0y1 is the table value at x0 and y1
* @param x1y0 is the table value at x1 and y0
* @param x1y1 is the table value at x1 and y1
* @return
*/
double bilinearInterpolation(double x, double y, double x0, double x1, double y0, double y1, double x0y0, double x0y1, double x1y0, double x1y1) {
double t1, t2;
if (y1 == y0) {
t1 = x0y0;
t2 = x1y0;
}
else {
t1 = (y - y0) * (x0y1 - x0y0) / (y1 - y0) + x0y0;
t2 = (y - y0) * (x1y1 - x1y0) / (y1 - y0) + x1y0;
}
if (x1 == x0)
return t1;
return (x - x0) * (t2 - t1) / (x1 - x0) + t1;
}
Please PM me all 3 of your input tables so I could check the calcs.

VGI, PM Sent with attachments.

If the Target Throttle X axis falls between 0.40 and 0.50, the values in this case at 1600 rpm are between 9.9 and 12.1. When I calc RT / RT Base (RPM) the result for me is 0.4805. I take that and view the Target Throttle table x axis and RPM and do a rough interpolation between the axis .4 and .5 and the resulting table values 9.9 and 12.1 which I guess is around 11.8 or so but not 14.47 as shown in the tool.
