So I’m not sure if this was filmed before or after you did your trans swap but I think you are forgetting to factor that in. It will play a role in this calculation and I didn’t see that you changed ratios anywhere

@TheCarPassionChannel

5 жыл бұрын

This was before the trans swap. If you're running a non-factory trans, you just need to calculate how much to alter the diff ratio to offset the change in trans gearing. For the E30 trans, I just need to do this: (3rd gear pull) 3.91 (diff) * 1.40 (E30 3rd) * 1.33 (Miata 3rd) = 4.12. VD only needs to know the final ratio, so you can alter the diff ratio input to counteract the trans ratio. Stock Miata 5-speed with 3.91 diff has a final of 5.20:1 in 3rd. With the Getrag trans, it's 5.47:1. So even though the car really has a 3.91, I need to do "4.12" * 1.33 (VD thinks 3rd is 1.33) to get the actual final of 5.47. Hopefully that makes sense. It would be much easier if VD just let you input the ratios on your own instead of having fixed values for the OEM transmissions in each car.

@@TheCarPassionChannel does the laptop or tablet have to be plugged into the ecu or the vehicle by the ODB-ll port ? And do I need to download mega log viewer ? Is it free ? Sorry for asking so many questions 😅

Just a tip if you or anyone else isnt aware, tuner studio has a feature called "triggered logging" you can set different parameters for it to start and stop the datalog. I use throttle position (TPS) > 50% to start the log then when the throttle dips below 50% it shuts it off. Great way to isolate a pull in a single gear since you have to left of inbetween shifts and since virtual dyno can only use one gear. A lot easier than dicking around with your laptop in your passenger seat while driving.

It's *possible* to do a pseudo Virtual Dyno with a stock ECU, using a stable/HD video camera on the tachometer, and using editing software to analyze the video frame by frame, to make a chart of RPM vs time (needs to be precise). Then make a 3 column excel spreadsheet with RPM, time in seconds, and throttle (pre-fill to 100). You can import that to Virtual Dyno. It's time consuming, and is subject to many innaccuracies (like tach being off, low quality video) but, it's possible.

The sae corrections are for na engines, for altitude and temp. For a turbo engine it is very different since the turbo can compensate by itself a bit, depending on how your calibration is done and how much you have left in your compressor.

4:15 how much hot sauce is too much hot sauce? Are we catching you on Hot Ones?

Since you cant really use the "dyno" numbers officially, it should be seen as a tuner tool for streettuning your MS or other programmable ECU. So as long as youre going down or up the same slope, each time, you can still use that part of the road because youre mainly interested in the changes in power rather than the absolute power.

Awesome very interesting thanks

wow mate like past 3 months i was developing similar app because i couldnt find anything like this you made my life so much easier but still my app was based on phone and just used accelerometer data and gps speed and use "calibration" to set rpms to certain speed this way calculate gearing still might be decent app to make no need for dataloging just phone with gps my app would use rolling on clutch pressed as drag calibration offset it on torque graph torque is just force we can calculate drag as torque going oposite side and add graphs together ive made some tests mainly in assetto corsa because i could just get a lot of data in short time but it should work fine in rl but for my use program you showed would be much much better thanks

That's the beauty of the program - you can use whatever means you like to get more accurate results. But the precise HP number isn't the main benefit, it's using the software to get multiple curves and use it as a tuning tool.

When I try VD, for some reason it doesn't start the run unless I'm WOT. So when I load my megasquirt log, VD only brings up a graph for the single part of the pull that is WOT. And it leaves out basically the rest of the pull that wasn't WOT. Do you have to go through the same problem? I duno if i feel comfortable lugging it at 2k rpm etc. Unless you do it and that's normal? Thanks Maybe somethings wrong with my settings. Awesome video again! this is going to be very helpful!!

You should be able to. VD can't import logs from all software, but most logging software (or logs) should be able to output, or be converted to, a .csv file which is very common. And VD can import .csv files. You may need to edit certain rows or columns of the .csv for VD to read it right (using Microsoft Excel or Google Sheets). Sometimes the tuning software adds an extra row on top, or titles a column weird, but .csv are easy to edit so it's usually a quick fix.
