    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.

    E85

    Okay Cyclone Stangs. Is there any drivers that would be interested in running e85? If a tune company is able to successfully duplicate the tune as well as suggested parts to run the e85 on. MPT Performance and I have teamed up to run test's of e85 and tunes on my car to see what the gains are. What parts you need to support the fuel, and what the long term of it all would be. If we are able to see decent gains, nice performance, and being able to duplicate the tune..... How many would be seriously interested?
  3. Datalogging 101 when using an SCT X3/SF3 handheld tuner Go to SCT's website download their device updating software:http://www.sctflash.com/support/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=25&nav=0 Download and install the Livelink Gen 2 software:http://sctflash.com/LiveLink.php Connect your SCT device to your laptop computer and update the firmware using the device update software Open the Livelink program and follow the onscreen instructions while inside your vehicle Select the PIDS(parameters) from the list of available options, ask your tuner which PIDS he needs to see Start the datalogging process With the SCT connected to your vehicle's OBD port and the Livelink program active, you are now logging all parameters you selected. You can do this simply to log your idle, part throttle cruise, or even WOT operation. For full throttle and high speed logging it is highly suggested you do this on a dynomometer for safety purposes.
  4. As some of you may know, MPT and I ran a trial on E85. It was a 50/50 blend on a N/A basic mod 3.7 V6. The E85 add on tune is NOW AVAILABLE.... You can get it HERE. I would highly recommend it for those running some sort of boost. Now for those who are not running boost. We are still going to run some tests with my mustang. Continuing to try different blends, full e85, long term use and such. So keep an eye out for those updates. Here is the Dyno Sheet from yesterday... We chose a blend mostly for convenience. No need to drain the tank. Plus it gave us the opportunity to see if the stock fuel system would keep up with the demand. Running 50/50 increased the octane significantly, allowing us to test for more power, but only required about 7-10% increase in flow from the fuel system. There's no need to modify the fuel system guys. There's is more than enough headroom with the stock pump and injectors to run E85... There's just not much to gain, performance wise. ....for a naturally aspirated 3.7 with minor bolt ons, the stock fuel system should be able to support straight E85. But AGAIN there is little to be gained.
