Most tunes will operate the vvt system either over a wider range or at a greater rate of change than the stock tune. Hemce a tune will put more demands on the vvt and will sgow up any latent issues |

I'm in Cali this weekend. Will it be helpful if on next weekend I post up some screenshots of how I use it?

I have an idea about what the OCV Current and OCV Duty values mean but the others are a mystery. I hope that the Aim, and Hold Learn values have something to do with that slowly-learned table for which people have been replacing the ECU. There is nothing sacred about how I laid out those gauges. Visual design is not my forte. :P

Not an idiot. The others have static non-zero values. I've discovered some related stuff in the manual. Still working to make sense of them. I also got some screenshots of Techstream in action. Will mark and upload ASAP. Tonight's our group's monthly karting meet.

I incorrectly assumed you were referring to the 4 target/actual groups. Something is definitely wrong if you only saw 4 move. Is that screenshot a realistic image of the ones that move; 3 valve, and the tach? That would mean: 1. your bank-1 intake is slewing properly, 2. your bank 1 exhaust is commanding a move but is not responding, 3. both bank-2 (intake and exhaust) servos are not doing anything. Here are the screenshots I promised. I'll explain them and then hang back until you're ready for more. I'm baffled by the gauges. Maybe the bank opposite the faulty side goes to zero so the driver can limp home on 2 cylinders. Maybe I'm giving the engineers too much credit. Here's the first way to make sure your fuel system is running in closed loop. I don't think it will let you manually slew the cams otherwise. Here's a better screen to see the fuel mode and all the VVT params. Here's how to get to the manual slew functions. Here's a clip of me slewing bank-1 intake (p0016) [ame]https://www.youtube.com/watch?v=RBqtg3Y3TD8[/ame] Here's another potentially valuable screen. Not yet sure what it means.

Appreciate the response. Was busy this weekend so I didn't tackle this but out of curiosity I tried OBDLink on my cellphone with just Bank 2. Still, some of the gauges aren't moving. I'll try TechStream later unless you got some other theories.

I suggest first looking for codes. Hopefully they will match up with what we saw with the monitors, that there is something wrong with bank-1 exhaust. Let's also both study the relevant parts of the service manual. I'll review again tonight.

Voila! Like magic, the dials seem to be all working. Not sure if that's normal values or not. Maybe you can chime in. Sent from my Pixel 2 XL using Tapatalk |
