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.

Supplier says Jeep Cherokee hack only affects FCA cars

Harman doesn't think that drivers need to worry about any further hacks of its products. The company supplies FCA's Uconnect infotainment system where a software vulnerability is responsible for a 1.4-million vehicle recall. "This experimental hack is unique to Chrysler," Harman CEO Dinesh Paliwal said to Automotive News. "This does not exist, to our assessment, in any other vehicle." The reason that the company wouldn't be involved is that automakers aren't simply plugging in the existing infotainment systems into new vehicles. According to Paliwal, Harman supplies the unit, but FCA and other automakers are able to make additional modifications for their vehicles. The National Highway Traffic Safety Administration has also recently taken up the question of broader software vulnerabilities in Harman's products. On July 29, the agency began investigating the company to check for similarities between Uconnect and the infotainment systems supplied to other automakers. The Jeep hack became national news when two researchers were remotely able to take control of a Cherokee. The vulnerability in the cellular connection even gave control over the brakes. "Once people get in the car and get into the CAN bus, then you can start to mimic and mess up many, many things in the car," Paliwal said to Automotive News. Politicians immediately responded with legislation to create federal standards in hopes of protecting drivers better. NHTSA also opened an investigation to make sure the automaker's software update actually solved the problem. Related Video:

FCA CEO Manley says alliances are still possible but aren't necessary

DETROIT — Fiat Chrysler Automobiles Chief Executive has a message for Renault SA and other would-be partners: We are happy to talk, but we can go it alone. "Strategically, we have a solid future and clear plans that are being invested in and are underway now," Mike Manley said during a session with reporters the day after the company released better than expected second-quarter results. "That isn't to say if there is a better future through an alliance or partnership or merger we wouldnÂ’t be open and interested to it." Fiat Chrysler is open to re-starting merger negotiations with French automaker Renault, Manley said, but added the French car maker is not the only potential partner to gain scale or plug gaps in Fiat Chrysler's technology or vehicle lineup. "To say are they the only opportunity, the answer to that question would be a definitive ‘No,Â’" Manley said. Fiat Chrysler in June withdrew a $35 billion merger proposal with Renault after French government officials intervened in the talks and sought to delay a decision on the deal. The Wall Street Journal reported on Friday that Renault and Nissan are trying again to reshape their alliance and resolve disagreements that helped to derail the merger talks with Fiat Chrysler. Fiat Chrysler has a commercial vehicle partnership with French rival Peugeot SA, and the two companies discussed a broader combination before Fiat Chrysler made its offer to Renault, people familiar with the situation have said. Manley said automakers are not the only potential partners. "There are cooperations that can help in specific technologies. There are cooperations as we think about the consumer-car interface," he said. "You could see collaborations that never would be there in the past." Fiat Chrysler's North American business is strong thanks to Ram trucks and Jeep SUVs, but in other markets the automaker faces continued challenges. The company is overhauling its mass-market business in Europe, which is anchored by the Fiat brand. Fiat Chrysler's Europe, Middle East and Africa operations were marginally profitable in the second quarter and achieved 1.8% profit margin in 2018. Manley has set a goal of 3% operating margins, well short of the 10% margins the company forecast for North America.
