1990 Throttle hesistation

[Schrade]

OK - now - FINALLY - got a continuous stream, no interruptions, at 2.5 recordings / second.

How do I upload a stream for everyone to look over here now?

Big veins = more blood flow = more energy = more fun right.

Select post reply - then attach file (paperclip) in menu at top of screen.

Also try transmit and receive timeout to 180 ms instead of default 120.
You could be right about the interference inside the vehicle. At least you've made some progress in getting a data stream to read.

Before 'AutoLogging Activated' turned itself off, it was creating a file by default. I added comments - a number; to distinguish from the last recording. It wasn't doing this with AUTOLOG Act turned off. And it wouldn't say to check that it was turned on either.

I swear musta' been MicroSoft people wrote this program...

So now, I can just upload a .UNI here? Only people with DM can download and play it?


Breakin' for a plate of grub and an Ale or 2 right now here...

Is this 2.5 frames/sec? That's slow. Are you using correct Baud Rate? 8192?

Also, I think your TPS% is too high for idle. What is the voltage showing as?
Should be between .53-.57v. What are IAC counts?

DM should have an Export file capability. Just create a .txt file that is comma delimited. Then you can use Excel to open it.

[Franke]

Anyone with datamaster can read your file but Datamaster can export the data to a csv. file which then can be converted with programs such as MS Excel spreadsheet etc. Select file - export engine data -

As xfire says...

[Franke]

Schrade, my tests show 0% TPS / .57v at idle 700RPM and 0 IAC Position.

[Schrade]

Those numbers were just ABOVE idle - not idle. THat's where the 'sag' seems to manifest.

Don't know if I got the baud rate setting correct or not. Is that a DM setting?

And how do I attach a .UNI file? It's not showing as a valid upload format... - only .zip (compressed format?)...

[Franke]

Smooth idle. At 1.6 % throttle opening, I'm getting a regular lope - like a vacuum leak. I don't believe it's a vac leak; I think it's electrical (DM manual says that the lost com could be electrical interference / voltage irregularity[???], which I think might also be causing the lope.

Throttle % bounces from 1.6% to 2.4%. Above that, back to smooth as silk again.

Got it. ok so its acting just like an off idle vacuum leak but you're thinking electrical? I don't have any thoughts on that one so have to think on that a bit.

Yep. can't up load uni file for sure as its not available. A compressed zip file will work. Baud rate is a laptop thing.
