Not the "tune' files, the actual "what happened" files.  Here's some Megasquirt examples, below.  Haltech should have the same ability.

Just because you told the ECU to do something doesn't mean it actually happened.  Plus, the quality of the trigger signal and it's timing should be there.  You might already have data from when the engine ran, stored somewhere.

Just another option.  It's looking like Plug 'n' Play isn't playing.  Which Haltech system are you using?  133 pages is too many to look back through.

Megasquirt also has a signal simulator that can be used to verify outputs are following inputs like they should.  I'm not recommending Megasquirt just saying that a company like Haltech should have similar.

Understood, however in this case the car is not running, merely turning over and backfiring a few times before dieing. I have seen the log files and can easily see the synch and home results with errors for the other tunes. The issue with the last "tune" was the meltdown instantly upon reboot of the ecu. The starter was not engaged and the car was not running.

I am running the Elite 750, but while i'm getting it tuned, It is the remorte tuner who sees the screen as I am over the engine holding the remote start button and feathering the throttle body....

Yeah, I don't see how the disparaging comments about rotaries would cause this much of an issue.

So I have no idea what I'm looking at with that graph. I mean, I can read the legend in the lower left, but I don't know what "normal" looks like. What's the horizontal time scale on that screen capture? It was running for minutes, seconds, a second?

What's Haltech's response to this whole thing?

What are the anomalous regions at the beginning and end of the run? Cranking at the beginning and struggling to run at the end?

 

It would appear so. I am reading about filter settings to see if they can be set to allow more "noise" from the Home and Trigger signals to smooth out the engine.
