Looking for Customer's Cars for Car of the Month

While we've always loved to see pictures or hear about our customer's cars, and we have held contests before where the winner is determined by who gets the most likes, we want to have even more fun and share a Car of the Month (COTM) every month.

It is an open contest and even if you haven't bought parts from us, we are ultimately car enthusiasts, and want to see your car. From mild to wild, $500 car to $5M car, we want to see your baby.

To compete in the monthly drawing for COTM, send us an email to: carofthemonth@lastcallracing.com

Please include the following information:
1) Pictures of your car
2) Main Modifications (or send us your whole list if you would like as well)
3) Purpose of build (street cruiser, drag racing, open track road racing, autocross, just for fun. etc)
4) Any awards or special acknowledgments from car shows, races, special events, magazine features, etc.

Winners will be drawn on the last day of the month for the following month.

When your car is selected, you will win a $50 store credit and we'll ship you a free t-shirt! We will also write a feature blog for your car and share it on social media.

No purchase required and this contest is open to everyone on the planet!

2016 Ford GT - Newly designed 50th Anniversary Supercar

Those familiar with Ford's Supercar, the GT40 was a 60's vehicle to be reckoned with as it proved to be a winner in the 1966, 1967, 1968 and 1969 24 hours of LeMans. The future for the GT off the track was short lived however and was discontinued until the remake in 2005 and only lasting 2 model years and just around 4000 units built.

Here now in 2015, a revived battle of the manufacturers to create the ultimate sports cars has reminiscence of the 60's. Ford is no stranger to producing great technology, and would not be left out in making their impact on the racing world and auto enthusiasts alike, hence they're introducing their latest version of the famous Ford GT40.

What once has large displacement at 7.0L, and went to a supercharged 5.4L in the 2005-06 versions is now a much smaller 3.5L V6 twin turbo EcoBoost engine. Some have already started the comments of how Ford would put in a smaller engine and does that make it any less of a supercar like the rivals of supercars today using V12 engines. We look right at F1 and see this is also what they're doing in a push for efficiency.

With cues we pick up from the LaFerrari, the 2016 Ford GT features Carbon Fiber body panels for the ultimate in weight savings while keeping a nice solid carbon fiber cockpit. The Drivetrain consists of the above mentoined 3.5L Twin Turbo EcoBoost engine coupled to a 7 speed dual clutch transaxle. Michelin was gladly on board to provide a special tire for this new supercar, and rightly so, the Michelin Pilot Super Sport Cup 2 tires will make it stick to the road and track.

Expect to hear more news about this car as the release date closes in and we get more information.

Tell us your thoughts on this new version of the Ford GT.

ECU Tuning - Unleashing the Hidden Power Within the ECU

At Last Call Racing, we are often on our Dyno Dynamics dynamometer finely calibrating the ECU's of the greatest vehicles made, but what is it that we are doing to the ECU?

ECU Calibration allows a person with knowledge of and experience with the physical and chemical actions and reactions taking place within an internal combustion engine to analyze data received from the vehicle's many sensors, as well as using professional lab grade external sensors and make corrections to the information within the ECU. Among the most important, this allows for the proper control of fueling based on fuel stoichiometry, mass airflow or aircharge, camshaft timing events, percent of cylinder filling (load), speed and load based volumetric efficiencies, fuel components (injectors/pumps), and fuel pressure. With the fuel aspect of ECU calibration, the correct mass air value is calibrated in order to supply the correct amount of fueling based on the above mentioned factors. Many aftermarket parts are focused on the ability to move more air, and when these parts are installed, the ECU often needs re-calibration.

Having our fueling properly calibrated based on corrected values for mass airflow, we can properly calibrate other important regions of the ECU outputs, such as Spark Advance, Variable Cam Timing, Electronic Throttle Control functions and when applicable, turbocharger wastegate duty cycles to control boost pressure.

We often find that the OEM does a very good job on mass airflow calibration for the stock engine as sold from the manufacturer. However, even with a stock vehicle there are often areas in the ECU calibration that have room for an improvement in performance. By commanding an A/F ratio (Lambda value) that makes better power for a specific engine and load value, we could extract more power and still retain a very safe and ideal A/F ratio. We also find vehicles with variable cam timing have a great amount of power hidden right in the factory components as we can control intake and exhaust valve opening and closing events, enhancing torque and power at all engine speeds. 

By properly optimizing the engine control unit, we can safely add torque, horsepower and a sportier driving vehicle while retaining or even enhancing fuel mileage, clean emissions and perfect drive-ability. Last Call Racing can help give you the best driving experience with your vehicle with our custom tunes. Contact us today if we can help answer any questions you may have about tuning your vehicle.
