Anybody see anything on this video? (best I could do for starters here - still learning software navigation...)

I think I'd rather look at the datalog as an .xls or .txt file. Not very clear and besides things happening too quickly.

Schrade,
Not sure how well monitor mode captures data but i can tell you that when i recorded my data after replacing the injectors and O2's, my LT counts were rock steady at 128 left and 129 Right in OPEN loop. RPM's were 775 at idle. In closed loop they moved between 125/130 Left and Right until i reved her to aout 4k rpm. At that time the LT counts went to 128 L/R and stayed there until throttle release. I noticed that your LT counts were moving in open loop which i don't understand as the ECM sets a constant 14 to 1 AFR. Maybe nothing to worry about but i thought the LT's should be steady in open loop. Maybe someone with more knowledge can help here and yes a .xls file could be helpful.

Correction to previous post. LT counts were 128/128 in open loop and ST counts were 128/129 in open loop. The LT counts stayed at 128/128 during the entire test but the ST Counts moved between 125 to 130 left and right until i reved her to 4k. Then they were at 128/128.

Franke,

The BLMs will be 128, especially if you disconnected the battery, in Open Loop. They don't change until it goes Closed Loop AND LEARN is ON. The INT and BLMs will got to 128 at about 4k since you go into PE mode at that point, so back into Open Loop.

Thanks XfireZ51 for the info. I did disconnect the battery to fix the injectors and O2's so I understand why the readings now. The ECM did have to relearn as I did tests with the old memcal and the newer Haibeck chip to view any differences. I saw an increase in MPG and a good emissions reading after a 25 mile ride down the hiway and back, then to the emissions testing facility. The BLM readings BEFORE the fix were very rich on the left side. LT was 115 consistently and ST was moving but rich always. After the fix LTs were consistant at 128 and the STs stayed around 128 +- 5 as well at idle and above. Looking at the histograms it showed the Fuel trim cells to be good at all RPM's. Good to have her back to normal.

Franke,

When I download a new cal, I reset the BLMs so that when I begin datalogging I am getting a read on the new settings. Since I use the datalog to modify the VE table, I'll drive the car for a bit before recording data. That way the BLMs on the new cal are steadier in each of the cells I hit. Otherwise you'll be relying on data that is still transitionng to its ultimate state. You'll get there eventually, but this shortens it up a bit.

I saw slight deviation from 128 (125L 131R, IIRC); if I can't figure out how to record a progressive scan in a day or 2, I'll try to get a better video posted...

Been at the speed shop ALL DAY, trying to get electrical 'noise' isolated from the A4 controller module. Still having the TPS lag, and it's causing a 2 MPH swing in Cruise Control function...

I'm hoping it will show up as a MAP issue / MAP voltage, in a scan...

Anyone know where the User's Guide is for DM?

Thanks here...

Schrade,
The software manual is on TTS Datamaster web site. They have a PDF version or a manual download to your computer.
Here is the PDF URL. http://www.ttspowersystems.com/softw...32man_v400.pdf

Looks like you can Export as a .csv file which I would have expected. Once done then review data in .xls.
