Hey guys, My VAGCOM cable came in the mail today so I couldn't resist playing with it It's basically the cable that dealers use to interact with the cars' computers and all of the modules, such as the ECU, airbags, immobilizer, and basically anything electronic in the car. The cable also has capabilities of monitoring engine parameters and can log them to a *.csv file. You can use this file to plot it in excel to see a real life visualization of what's going on in the engine. This is a graph showing Engine Speed in RPM (blue) Throttle Position in % of WOT (green) Engine Load in % (red) and Cylinder 1 spark timing in degrees before top dead center This shows a moderate acceleration run from first gear to fourth. I max out at about 80% engine load while the clutch is engaged (probably due to elevation correction and humidity). During first gear, I didn't have the pedal to the floor, as I wasn't trying to do a full out run, but during second gear, I said the hell with it and put the pedal to the floor resulting in 100% throttle postion. Didn't continue with Wide open throttle (WOT) into 3rd gear because of speed limits. Also my car redlines at 6500 RPM so it wasn't a true holeshot. When the weather is better I'll do one and post results to here
This image shows the calculated speed of the car per rpm of the engine - it was calculated with gear ratios and tire size
If this kind of stuff interests anyone, please say so and I'll do more
did another one, the weather was nice :P
