3V Mustang Datalog/Tune Questions
Hey guys, new to the forum and working on tuning a 2006 Mustang GT for the first time. The car has a Hellion 76mm turbo kit, some mild cams, engine work and a ford racing intake manifold. I have the Ford Beginners guide from The Tuning School and went to their class last month, but I'm running into a few things that they didn't cover. I'm currently on the dyno, worked on MAF tuning yesterday and feel confident that the MAF is close until around 2.9V on the table, and from there it's close, but I keep having the AFR's change in between the cells in the Airflow Vs. Voltage table. For instance, at 3.88V on my table, the AFR's are about 1% off from commanded, and the next cell is 4.15V the AFR's are similar, but in between those 2 points, the AFR's fluctuate almost 2 points. Is this an issue that I need to add more resolution in the areas that this is happening and take some resolution from where the AFR's are stable?
Next issue is that I'm having trouble finding info into tuning the Load with Failed MAF table. This wasn't something covered in the book and I'm not on a load bearing dyno to tune the way Greg Banish suggests in his DVD. I started looking into hystograms for this, is that the way I should go?
The next issue I'm having is the way they describe how to monitor knock. When I added the Knock Sensor 1 and Sensor 2 Pid's to my datalog it only shows a value in mV and does not plot on the chart itself. Really fuzzy on how the Borderline knock table and MBT tables work, is there any other posts that you know of that I could reference?
Thanks for any input and feel free to post up a previous thread that may answer these.
