Techstream and Technical Engine Management Sharing Thread

Hi all,
I started this thread as a place for techs and hobbyists to share information and learn from each other. Let's share Techstream hacks, analysis, and customizations with each other and see how much we can collectively learn about how this new engine and transmission works. Have fun and let's keep it respectful.

 

Hacks?

 

The goal is to pull together and promote understanding and/or troubleshoot engine control issues in our trucks. Rather than carrying out the engine management related conversations over multiple threads, we can consolidate the conversations right here.

For example, I will be data logging looking for what might be causing the "miss" that people are complaining about as well as what is different about the ECT mode (besides shift points).

 

With what gain at the end? Widely knowing that Toyota does not allow changes to ECU programming.

 

Me too!

 

Mostly to promote understanding for the participants. For example, we did this before, with a large group, and figured out the cause of the shift flare in the Aisin AC60X transmission and helped Toyota solve the issue with a software patch (some know is as the rev1 transmission TSB). We would like to help Toyota with rev2 that may silently fix a few more engine management quirks.

 

The issue was figured out by a group of posters. Some of them, including myself, worked with Toyota Engineers, feeding them information. Their TCU programmers wrote the patch.

 

Source?

 

Me.

 

and I'm a billionaire

 

Let me see what I can do.

Then search my name. You may be pretty busy.

I hear you, but was due to people complaining to dealer. I've had TSB and still have flare, so don't believe they have addressed that. Yes they have addressed the reverse to forward delay, IMOP, but the rest remains. I honestly don't believe that Toyota sits on TW and looks for issues and problems with their vehicles.

With few posts I saw you post in a quick glance, there wasn't any evidence you actually had any data or any evidence of contact with said Toyota engineers or Aisin people. If I were to take you seriously, you'd need some credible info for your findings like this guy building an arduino based s-mode shifter board

Perhaps you are right. I communicate directly to a VP in Toyota though, and my correspondence is usually passed down to the engineers. I am an engineer myself. As for your flare, did you have the rev1 of the TSB applied to your truck? What flare are you still witnessing? Cold engine?

 

I can respect that. In fact, I don't blame you. There are a lot of fruit loops on here. Stay tuned. In time you will have your evidence.
