Re: 1990 Throttle hesistation
Chuck,
If you go to page 15 of the DM manual, (http://www.tunercat.com/Docs/DM32man_v400.pdf) you'll see that you can export data as a .csv file. That will allow you to look at it using .xls. Just record your throttle position session and then you can review whats happening. Makes things much easier.

I have ONE, at least, which is not within spec. And without a DTC, I have to essentially see the whole operating system. I think Windows is easier than this (and I do Linux OS). Command line interface doesn't scare me, but reading fuel trim cells - hmmm ... I did the comma separated values data file, posts 37 - 39, this thread. Posted format didn't come out too well, and pertinent values might not appear, but I'm working on it. Even BEFORE that, I need to know WHICH values to include in the 'Bit Data'. EGR duty cycle, and Vehicle Speed, for example, aren't necessary...

Re: 1990 Throttle hesistation
Marc does it slightly different than I do. He turns them on >0% throttle. works well either way.

Re: 1990 Throttle hesistation
Chuck,
Looking at what you posted, it seems like you get all the parameters in the data stream. So yeah, just record that and export it as a .csv file.

Re: 1990 Throttle hesistation
This will be over NO time soon. It's a comedy of errorS, or a Greek Tragedy - depending on who's holding the wrench.
Got everything bolted back up, ready to manipulate the throttle stop bolt for DM recording, and lo and behold, the coolant by-pass line had jumped the casting ridge on the A/C compressor again - bound under the primary butterfly shaft. I was cursing. Got it un-zipped, freed up the line in 3 minutes, back together. Then the last TB extension bolt fell out. It is no where to be found. Then I REALLY started cursing. And the D side coolant manifold elbow is leaking - can't tell if it's a loose gasket, or ruptured elbow. Next up; drain the coolant from the cross-over pipe lower, pull it, and pull the serpentine belt, to get a better field of view. Hopefully, the bolt will show without having to break down block front accessories... This is getting really discouraging.

Switch Throttle Bodies
What I do because I have spares of everything for three corvettes (two Zs) is switch from suspect bad component to known good component. Then leave good component on if that is the case and when time is available .....fix bad component if fixable
This involves little time, NO immediate component testing.........and NO DISCOURAGEMENT...........usually Quote:
I have found injectors from previous maintenance there for example.
