How to tune a car right: Part 3, tuning Mopar with OST Dyno

Not long ago, I wrote a story about a pony car tuned with a supercharger. The blower install had been done properly. Then the car's owner bolted on a set of great looking wheels wrapped in good looking but inexpensive rubber. On my first test drive, I couldn't get any of that supercharged sweetness to the ground. It was the perfect ride for parking in a Burger King parking lot on a Friday night. I tooled around on a Sunday drive, shaking my head that someone had spent five figures to get more power the right way, with a clean install, then wiped out the gains so thoroughly that the stock engine would likely have overwhelmed the tires. This got me thinking about the ways people ruin their quest for horsepower, either on the front end by not insisting on a clean install and paying the money for it, or on the back end with supplemental purchases like cheap tires or cheap gas. So I called three tuners, one focused on GM, one on Mopar, one on Ford, to find out what people should know about how to get the best power for their goals, and how to make sure they are able to use all that power. The first interview in this three-part series was with Blake Leonard at Top Speed Cincy in Cincinnati, Ohio, the second with Brandon Alsept at BA Motorsports in Milford, Ohio. This third and last interview is with Micah Doban at OST Dyno in Slippery Rock, Pennsylvania, a family business with more than 40 years of Mopar expertise specializing in Gen III Hemis, but tuning everything from land-speed cars and drag racers to Jeeps The interview has been edited for clarity and concision. Do people who come to OST generally know what they want? Probably 80% of the people who come in simply want more power with no particular ET goal [ET is a kind of bracket handicapped drag racing – ed.]. WhatÂ’s the best way to start a Mopar tune? The first thing is what people often skip, and that's to find a tuner or a shop. People will throw parts on their cars that the Internet said to, then go to a tuner who does things a different way, and [the tuner is] like ‘No we don't like to use these injectors, we don't like these parts.Â’ You have to find someone familiar with the parts that are on your car or that you're planning to put on your car. So having a goal and then finding a tuner who can help you with that goal is proper way to start. Exactly. And a lot of tuners have their own formula – and when I say tuner I mean someone that also does work to the cars.

Prosecutors indict three FCA employees in alleged emissions-cheating case

Federal prosecutors indicted three Fiat Chrysler Automobiles (FCA, now Stellantis) employees as part of an investigation into alleged emissions cheating. Charges unsealed on April 20, 2021, accuse the defendants of helping rig the emissions control system fitted to the 3.0-liter turbodiesel V6 used in some models during the 2010s. Prosecutors claim Emanuele Palma, Sergio Pasini, and Gianluca Sabbioni played a determining role in developing a defeat device that allowed the V6 to obtain certification from the Environmental Protection Agency (EPA) while polluting too much in normal driving conditions. Jeep and Ram began making the engine available in the Grand Cherokee and the 1500, respectively, in 2014, but the charges state plans to game the EPA started in 2011. Palma, Pasini, and Sabbioni knowingly mislead federal regulators, the charges claim; they called it "cycle beating," according to The Detroit News. While the three men were part of FCA's research and development department, they started the project while working for an Italian supplier named VM Motori, which FCA purchased in 2013. Pasini and Sabbioni are each charged with one count of conspiracy to defraud the United States and to violate the Clean Air Act, one count of conspiracy to commit wire fraud, and six counts of violating the Clean Air Act. They could spend several years behind bars if they're found guilty. Both are currently in their home country of Italy. Palma's legal troubles are more serious. He was charged with several counts in September 2019, though four wire fraud charges were dropped in November 2020. He lives in Bloomfield Hills, a city located on the far outskirts of Detroit. Prosecutors claim motorists spent over $4 billion on over 100,000 trucks and SUVs fitted with the non-compliant engine between January 2013 and September 2017. FCA has already agreed to pay $800 million to resolve civil claims from the Justice Department, state officials and customers, though it significantly has not admitted guilt. It stressed that "it did not engage in any deliberate scheme to install defeat devices to cheat emissions tests."

332,000 Jeep, Fiat and Alfa Romeo models recalled over faulty seat belt buckle sensors

Stellantis has recalled 332,000 Alfa Romeo, Jeep, and Fiat vehicles in the United States due to faulty seat belt sensors. Included in the recall are certain 2017-2024 Alfa Romeo Giulia and 2018-2025 Stelvio models along with 2019-2023 Fiat 500X, Jeep Renegade, and 2024 Fiat 500E models. According to documents posted by the National Highway Traffic Safety Administration, "A disrupted connector on the buckle switch hall effect may affect the conduction on the connectors of the seat wiring and buckle which may cause the front seat air bag to not perform as expected during a crash." In more simple terms, the sensor that tells the vehicle's onboard computer if an occupant's seat belt is buckled may fail. If this happens, an airbag may not inflate in the event of a crash as intended. As of June 26, 2024, Stellantis says it has identified 578 field reports in North America potentially related to this issue. "The remedy will be to replace the connector by directly wiring the sensor to the harness with a solder tube," according to documentation provided by Stellantis. All repairs will be made free of charge.
