I had about the same issue when I did v5 code. Lost vss. Jumping all over. Was not sure what happened , went back to 4145 and back to good. Got truck registered and on the road and fount out that trans slips soon as is it completely warmed up and it's a valve body issue with the 4l80e. So until I get the mechanical issues done I have been running old code and will dig into this issue before I rebuild. But guil isn't the only one who has seen This.

Lance, thanks for your answer.
I switched to the old version for the moment.
The datalog with the new code is in my previous message, in the link, you can download it as it was too big for upload on the board.

Guillaume,
If the problem can't be seen in the datalog (I think that is what you said), there's no point me looking at it. What I need is a datalog that clearly illustrates the problem.
You can normally edit datalogs to show only the relevant information while still being small enough to load here. You can do this in any text editor (like notepad++). Don't touch the first four lines, which will look something like this:
Code: Select all
"MShift 5.101 : ** V5.101 MegaShift by B&G **"
"Capture Date: Tue Apr 28 06:10:05 PDT 2015"
Time Seconds Mode Speed VSerr VSrst RPM miles load avload decel TPS rMAP arev mpg in1adc in2adc in3adc swA swB swC swD lverr soln Out1 Out2 Out3 Out4 Out5 Out6 Out7 Out8 Out9 UP DWN Dreq Ureq hyst led1 led2 led3 led4 block fUP fDWN Jake buadERR shftBut cGear tGear mGear eGear gErr TCC TCChyst Brake VSSHz OS IS slip cltF line auxCH Error PC% Sp0% Sp1% Sp2% Sp3% dbug burn 4WD sp0x sp0y sp3x sp3y ptA ptE srpm cruz Vper iRat wRPM idlAdj spkAdj

Then you can remove *whole lines* after that (it helps if you turn "word wrap" off in your editor). So this:
Code: Select all
"MShift 5.101 : ** V5.101 MegaShift by B&G **"
"Capture Date: Tue Apr 28 06:10:05 PDT 2015"

Finally, note that though the VSS code (technically the interrupt service routine) has not changed with the 5.xxx code with the old VSS routine, the interrupt handling has changed quite a lot. That will likely mean you need to retune the input masking, smoothing, error handling, and minimum and maximum speeds for the VSS when moving from any 4.xxx code to 5.xxx code.

I put the input masking to 75 and then to 80.
FWIW, on the bench, with the VSS signal coming from TransStim, I also had to go up to 80% to get a good VSS input. Within the next few minutes I should know what happens on the car with the actual VR signal coming from the VS Sensor.

Hello lance,
You can see in the datalog that the speed stays at 0 (sometimes 0.5km/h with the new beta vss isr)
It was when I was triying the old vss isr that I had spikes on the speedo and these spikes could not be seen on other msl files.
For the msl, i manage to shorten the time to make them shorter, but what I did not manage to make yet is to remove columns to keep only the usefull data for Mshift and remove all the fuel and spark calculations from MS3 for example. with all the parameters, the files can become very large even for a short period of time.
thank you for your explanations, I will try to modify the parameters in order to improve the speed input.
Regards
Guillaume

Guillaume,
The best way to get a nice clean MShift log it to use the serial port on the GPIO board to connect to the laptop (with a project that has only MShift in it - no CAN devices). MShift will still grab all the data from the engine ECU over the CANbus, but the log will be *much* smaller.
Lance.
