So I've been using HpTuners for about 4 months. Compared to other PGEFI systems I have used I find the scanner side very difficult to use. I say this in regards to it is very capable and options are limitless it seams. But They are so user defined that setting up the scanner for your needs is a real pain in the butt.
I have three questions. First I am using software version VCM Editor 2.24.57 Vehicle is 2002 Chevy 2500 8.1L with STS turbo. converted to 2 bar MAP and changed to 2Bar Speed Density.
#1 My friend has HpTuners for his Chevy truck and his Corvette and we have avidly used the RTT (real time tuning) I think his software is on step older than mine. But anyways we cannot get the RTT to work on mine. I've followed all the instructions to turn it on but the icon just simply isn't there to turn it on in my software. So..........? Does my software support this function? How can I get it? Or... can I get it?
#2 I am trying to set up a histogram to record the "Idle Airflow - Desired Airflow" for tuning base idle air flow. This thread makes a lot of sense. http://www.performancetrucks.net/for...tricks-373848/
How ever search as I may finding info to actually set up the VCM scanner side to actually be able to data log and believe the info is correct based off the required user setting to make the histogram even exist is hard to find. Someone seriously has had to post a thread about VCM scanner setup. Easy how to's and do not's. My question for setting up this particular histogram is what sensor inputs would you use? The Base Idle Airflow table says its Idle airflow vs Coolant Temp vs Gear&PN. That's great...... but what sensor does this table depend on for a derived Idle Airflow measurement? So much of the GM table code seams to want to measure in (cylinder airmass g/cy) ignition timing tables do this. I assume this Base idle table uses the same method? Which confuses me because its a Speed Density tune now. How does (cylinder airmass g/cy) relate? its as though its still a table built around the MAF g/s measurement but..... how? Some setup help on this would be appreciated.
#3 ever since I've been dicking around with the Base idle table and trying to make sense of getting the histogram to work and even know what sensor input to use and how to even believe the information it's posting in the histogram..... somehow all my histograms are messed up now. All the histograms work off some measurement vs RPM populating PIDs based off RPM and whatever measurement for whatever histogram you're looking at for that moment. Well now my histograms only populate the 400rpm column. doesn't matter if its ignition main spark timing advance, knock retard, fuel trims, AFR error the histograms only populate the 400RPM column at any RPM. its like all the information that would go to all the different PIDs is just all being stuffed into the 400RPM column. I'm sure it's something I did that messed it up but I've spent the last two days trying to figure out what I did to mess it up. I can load up the generic default metric VCM scanner config and all the PIDs populate properly. So this tells me there is something I messed up with the user parameters. I would rather fix my problem then remake an entire new VCM scanner config again because I cant figure out what I messed up.
Any help would be appreciated. I can't be the only person to have these difficulties. There must be a thread or write up to address most of these issues and if there is please reference it to me. I just feel like for every step I take with the stupid VCM scanner I take two steps back. The VCM editor side I don't have issues with. I just hate how generic the VCM scanner is and if you want to actually data log you have to set so much up to get what you want. To me the VCM scanner is a setup nightmare. Guess I've been spoiled in the past and I'm a pansy but I am really surprised how difficult setting up the VCM scanner is.
Thanks in advance
