A lot of advice given on Facebook can be crap because everyone seems to be a know it all but it’s sometimes harder to get a response on here on the forums. In a lot of cases the open source stuff has...

Try this. There has been several updated versions since.

Here’s what is it looks like and the xdf version I was just looking at. Sorry about the glare. I was outside. It’s the 2156 v3 xdf. Maybe the xdf you are using doesn’t have those tables.

There are 2 tables under engine diagnostics for the etc predicted airflow. Nothing I’ve had to mess with but could start there.

Do you know what operating system you have?

Welcome. I’m in West TN.

That’s understandable. I’m wondering if the video you saw was mine. Here is a link to the 7603 xdf file that I mostly use with tuner pro. I plan on getting more informative videos out.

What operating system are you working with? With this tableseek that was just put out you should be able to enable all settings in universal patcher and not even need to mess with TunerPro.

That’s awesome! Thanks.

Yeah that’s the one I’m looking for. I used an XDF to change this already but was hoping it could be added to the tableseek so an XDF wouldn’t be needed. Thanks!

I was hoping to see the table for Fan 1 on with AC on coolant temp setting but I still don’t believe it’s in there. That for me is a key one to getting electric fans to work with AC at idle and lower...

I have the newest version and now Im trying to dive into the logger and histograms. Here’s a couple issues im having so far that maybe can be looked into.

1 - What looks to be a math pid...

This really isn’t a concern on my truck because I have access to the VE table but let’s say I’m looking at a vehicle I don’t have access to view the tables. This was more of an idea I had to use as a...

That makes sense to me. I found a table with the allowed differences in calculated airflow vs actual airflow. Just trying to see if some math can be done using known PIDs to view what the calculated...

I am curious if one can do some data logging with the available PIDs and open with a log viewing program then create a math equation to create the calculated air flow to compare it to the actual mass...

I’m wondering if anyone knows how GM gets it calculated mass air flow. I found this calculation MAF (lb/min) = [(Displacement *RPM/2)/1728] * 2.7 (MAP/IAT) and a few like it online but that’s for...

If you are using TunerPro you have to count the numbers of rows and columns of the table you want a histrogram of on TunerPro then enter that number in the table dimensions to the left of the...

I use PCM Hammer and Megalogviewerhd to create historgrams. 1794917950

Nice. I am from the Memphis area myself.

Yeah I fine tuned my maf and ve table a while back and got it within that window. There is a table that adds spark based off afr and I had it copied from the Holden file. No luck as of yet.

It actually seemed to decrease my in town fuel economy by about 3/4 of a gallon per mile. Went from 10.5 to 9.75. That’s with is leaning out to 16.5 to 1. Leaning out to a bit over 17 got me only...

I just sent you a debug log and a data log.

I have actually used Universal Patcher logger quite a bit the 3 weeks I was getting some irregular jumps in rpm readings sometimes. Let’s say I’m running a constant 1500rpm I would get quick spikes...

I just ordered one of those yesterday. I’ve been using the obdlink sx. Kinda slow but gets the job done. I log with the PCM Hammer logger and create histograms with Megalogviewerhd. I also use the...

I checked my data logs and on a steady 68 mph and my MAP sensor reading is sitting at around 55kpa at 16.9:1commanded afr. MAP kpa is around 30-35 at idle.
