This was a good log, it seemed to work ok at WOT except for lowering the pressure a bit during the 1-2 shift but that's not a huge deal. However when you were coasting back down it looks like your...

Perfect, it seems to me like the load is not calculated correctly for the engine so it does not command the right pressure. It only really cranks up the pressure (lowering force motor amperage)...

Those two have the PIDs i need but the sampling rate is horrible. It makes it look as if the computer is commanding 1-4 instead of 1-2-3-4. I am good at looking at log, unfortunately I have very...

LOL It is not a file you open like that, it is meant to be loaded on your computer in the channel config folder of HP tuners so that you can select it and then it will log all the pids listed in...

Here's a channel config file that will select the transmission PIDs I need: 146330

Without a log I can't really help but there is not a whole lot on the control side of things that could give you a harsh 3-4. Is this a rebuilt transmission or a used one? If rebuilt, any idea what...

OK so aside from having only stock pressure your transmsision, it is capable of doing what it needs to do. Don't mess with the solenoid calibration screw, that's a big mistake many people make, not...

A transducer would be awesome of course since we could look at the log and see if the pressure matches the pressure control solenoid command, but it is not a must. All I really need to know is that...

If that was for me, it is a log I need to be able to help, not the tune.

You did not record any of the transmission parameters aside from the current gear and PRNDL so there is no way for us to know if it is working correctly or not.

I can't help with any tuning issues, but if you post a log with the transmission parameters recorded and let me know what your line pressure is I should be able to tell you why the transmission keeps...

This is very difficult to follow. Post a log with all the transmsision parameters recorded of it going in lock-up and then unlocking and I might be able to help.

Oh I did not realized you were not the OP! Now I see what you mean. I have no idea why the polling is so slow in yours, I would open a support ticket if it was me or start a new post of your own with...

Can you take a screenshot of the "spiky straight lines" you are talking about, and attach it here, so that I can see and understand better what you mean. On my end looking at your log, the PIDs you...

Yea Sean Boyle does a great job as usual explaining each phases of the shift and it was quite interesting to follow along as he was doing all the testing. I will let others that know about tuning...

The command for PCS 2 needs to change so that the 3-5 clutch it controls does not start to apply so quickly. It is applying during the fill phase of the shift (see attached graphs showing the 4...

There is a way to go around the problem that removing the wave causes, I just don't know how it is done in the tuning, that's not my strong point. No need to raise pressure on those they already...

I don't know enough about tuning to know how to go around the problem that way. But removing wave plates, adding frictions or reducing clutch pack clearances always cause headaches on those. Not to...

Amen

You did not log all the transmission PIDs so it is really hard to figure out what is going on with certainty but it looks like the converter is locking up as commanded. The high stall is probably...

Ok well that makes a lot more sense then. Thanks for the clarification.

Thanks for explaining, I am always trying to understand better the racing world. Getting better top speed I get, but a few tenth is surprising to me just because I would think it would slow them down...

Post a log so that we can see what is actually going on when it is acting up. Be sure to include all the transmission parameters and to log both cold when it is acting up and warm once it feels fine.

Glad it is working good now. Scary that they did not find the alignment issue, hopefully it does not happen again. Thanks for taking the time to post this update.

Thanks
