Here are just some of the many vehicles that I have tuned with more to come. Enjoy!
A rare Mustang obviously. The mass air transfer function was recalibrated due to the larger cross sectional area of the inlet pipe and the conical filter. It would have been very lean without the recal - more than the adaptive trims could have attempted to correct even at their clip. Fan control, electronic throttle control and open loop WOT fuel tables were tweaked. Additional spark was also added. Since the Shelby's come with the standard Mustang GT's catalyst package, the catalyst temperatures are very high thus the cat and HEGO temp protection models were left enabled in stock form. Thus these cars benefit greatly from an aftermarket exhaust. Ernie has a few authentic Shelby's in is stable too!
Wow! Nice work here. A 1965 restoration with an entire 2003 Cobra powertrain and suspension installed in it. ABS and traction control both work. Also note the satellite radio, CD system, power windows and door locks and custom gauge pack installation. The start button is from a Ford GT. One trick feature is the license plate retracts when the car is running to clear the Shelby exhaust tips. This car is loud as it only has underbody resonators installed. The main work on this chip was conversion to a return style fuel system versus the stock returnless fuel control.
2001 Roush Mustang GT Rob has a clean Roush Mustang that was very low with its springs and ground effect package. We had to drive up wood pieces to allow the jack to get underneath to install the airfuel meter. The chip required a remapped airmeter transfer calibration due to the JLT cold air kit which uses a larger MAF. Traction control was also turned off for the summer months. Premium fuel spark maps were also utilized.
2007 Mustang GT Jim owned this car only a few weeks before he wanted a premium fuel performance tune for it. The electronic throttle controls maps were made more aggressive as well as the throttle rate tip-in controls was modified to allow for appropriate throttle speed matching during downshifts. All 2005+ Mustang GTs suffer from a sluggish throttle tip-in with the clutch in. Since Jim races this car, correcting this issue was a necessity. Furthermore the knock sensor control was also made more aggressive. Jim has reported that the car pulls stronger and even gets better fuel economy. Jim installed his own stripes and has since installed the Ford Racing suspension kit along with 275 series tires on Shelby GT500 chrome rims.
2006 Cervini Mustang GT Jim purchased this car new and immediately installed the Cervini body kit complete with side exhausts. This car received the typical premium performance tune along with a valet mode with reduced power, speed limited and lowered redline.
2005 Vortech Mustang GT Rich's very nice 2005 GT has an 8 psi Vortech kit on it flowing through a stock exhaust. After the base installation and the Diablo chip that came with it, the car was sluggish and would not accelerate at part throttle. After the custom chip, the throttle response was smooth and aggressive. This necessitated remapping of the electronic throttle control, variable cam timing, MBT and borderline spark renormalization, knock sensors, aircharge temperature compensation tables, etc. due to the high loads and system design. The owner was ecstatic with the new tune.
2003 Cobra SLP Cobra Loud Mouth catback exhaust and SLP M23000 95mm Mass-Air-Meter Package. Note: Stock pulley
2004 Cobra SLP X-pipe and catback exhaust with a K&N cold air intake. Note: Stock pulley
2003 Mach1 A/T MRT catback exhaust, K&N filtercharger, Paul's High Performance intake spacer, and 4.10 gears. JD can lay rubber on the 1-2 and 2-3 shifts!
Note that the transmission was calibrated to stay in 3rd gear with a locked converter during dyno testing. The stock chip testing was run up in 3rd gear above the 3-2 kickdown shiftpoint at 3500 RPM.
2001 Saleen Supercharged Mustang SLP headers and no cats.
2003 Mach1 M/T
Erik ported his intake manifold himself. He also has a K&N filter system and a MRT H-pipe. See the detailed description in the Mach1registry forums.
2000 Cobra R (Number 124 of 300)
Scott is an avid and experienced road racer as well as a board member of the Central Illinois SVT club. He baselined his car without the x-pipe and chip on October 16, 2004. On the stock chip it was needlessly running very rich (<10:1). With the SCT XCalibrator system he now has two custom tunes featuring 12.0:1 and 12.5:1 open loop WOT settings. Features included with the provided tune options were: a more aggressive spark calibration, a corrected vehicle speed calculation for his smaller diameter racing tires, OBD-II modifications to eliminate the check engine light due to the catless exhaust, and cooling fan improvements. An additional tune was reserved to correct some part throttle driveability issues he has also experienced with the stock tune.
