    Tuning 101

    This page will be constantly updated to be as up-to-date as possible with the best accuracy. Learning how to tune a modern car is a completely different animal and takes months or years to perfect. Tuning basics: Ignition timing, knock Air/fuel ratio, aka Lambda/lambse, stoichiometry Variable independant camshaft timing Ignition/spark timing: During WOT operation having proper spark timing ensures the air/fuel mixture is completely burned for maximum power. If the spark occurs too late the air/fuel mixture does not burn completely before the exhaust valve opens and power is wasted. If the spark occurs too early the air/fuel mixture can ignite when the piston is still rising on the compression stroke and severe engine damage can result. Knock is the common term for when the ignition has advanced too far and makes the distinct sound of knocking or pinging. Our cars have knock sensors which can detect this and allows the ECU to determine how much ignition timing current conditions allow for maximum performance. When looking at datalog, the PID KS will show positive and negative numbers. A positive number shows timing being retarded by the knock sensor, and a negative shows the timing being advanced. Air/fuel ratio, lambda/lambse, stoichiometry The 2011+ Mustangs utilize lambda sensors, which are more commonly called wideband sensors. These read air/fuel ratios in a constant closed loop which means the ECU makes it's a/f calculations with constant data from these sensors and not just from a table. In a datalog this shows up as lambse(short term fuel trim). Stoichiometry is the term for the exact amount of air needed to completely burn a volume of fuel. For gasoline this is commonly known as 14.7:1 and abbreviated as stoich. Lambda is a different scale with stoich set to 1.00. Lambda 1.00.......................AFR 14.7:1 Lambda 0.90.......................AFR 13.23:1 Lambda 0.85.......................AFR 12.5:1 Lambda 0.82.......................AFR 12.05:1 Lambda 0.8O......................AFR 11.76:1 For maximum power however, additional fuel is added and adjusted as tuning is performed. A common air/fuel ratio for a naturally aspirated 5.0 is between 12.0 and 12.4:1. To make things a little confusing, Ford changed the stoich value of Lambda from 14.7:1 to 14.079:1 This was done (at least partly) due to ethanol content in today's fuels(~10%). Ethanol has a much lower stoich than gasoline, 9.01:1 for 100% and 9.77:1 for E85 so this is enough to alter the fuel tables. Variable Independant Camshaft Timing http://media.ford.com/images/10031/TiVCT.pdf New for the 2011 5.0 and 3.7 engines was Ti-VCT. Having a separate camshaft for both intake and exhaust valves, plus timing control for each by way of adjustable sprokets(with a maximum of 50 degrees adjustment) allows tuners a new measure of tuning control. For basic tuning, advancing the camshafts increases low end torque whereas retarding them increases top end power. With independant control both can be had.
  2. So, long story short, I'm troubleshooting some charging issues with my 2011 Shelby. It is PCM calibration related but my question is how much is too much? My FRPP tune shows 15.2-15.5 volts which I know is waaay too much. This is the root cause of an issue I have...but that's another story. The stock tune, shows 14.2-14.4 volts which I think is more in the ballpark depending on charging system demand. My question is, what is max/peak it should ever show at the battery? I'm guessing low 14s but would like some confirmation.
