There was tons of eye candy at the UpRev shop. Our project was one of the few non-supercharged cars.
After a cooldown we tried adding some fuel to see how the car liked that. It didn’t so we backed that off as well. Since we’re not running an oil cooler on the car we only get a few runs on the dyno before heat soak sets in. While the car cooled we took a break to go grab some BBQ for lunch, more on that on the next page.
Omar works his magic on the ECU on the ‘background timing’ tables and after lunch we pickup 3hp and 3 lb/ft to 311hp and 258lb ft. Through the rev range we’ve got a few spots where we’re seeing a 6hp improvement over the stock tune and that as they say is where it counts. Keep in mind we’re making more power and we’re running the car in a much safer state of engine operation vs modified with parts on the stock ECU. As a final step Omar works on the drivability dialing in some more timing at my freeway cruising speed so the car leans out a little more for better highway mileage. This is all being done while he’s keeping an eye on the air/fuel ratio to make sure the operating conditions are as ideal as possible. He also addresses the torque converter lockup and is able to get the transmission in a place where the converter is close to fully locking up.
Omar’s tricks work; we pick up nearly 4 more horsepower to just shy of 312hp. The comparison dyno shows where we started stock and where we finished.
Another thing to think about with the OSIRIS Standard (or Tuner) beyond the horsepower are all the other features included. I’ve got 5 maps to choose from on the car now. Map 1 is my performance tune that Omar worked on. Map 2 is my lower octane map in case I get a bad tank of gas. Map 3 is my valet mode where engine RPM is restricted to 3500 and speed to 35 mph. Map 4 is the security map, the car might fire up on but it will empty the remaining fuel in the lines and then she’ll be dead. Map 5 is open for now as we didn’t have the need for it at this time. Omar tells us this map is good if you’ve got teenage drivers you want to limit to 70mph.
To switch between the maps: hold the set/coast toggle down, press the Cancel button once for the first map, twice for the second map and so on. When you release the set/coast toggle the cruise set light on the dash will blink a corresponding number of times for the map that you chose.
These are awesome results from a made in the USA product from a bunch of down to Earth hard working guys. The word in the shop is they don’t usually see dyno numbers like ours unless someone’s running straight pipes which says a lot about the quality of the breathing modifications we’ve done. In Austin it has been raining for at least two days straight now but I had to take the car to try out all the newfound power. The brakes also need to be properly seated so the conditions were worse than we’d hoped for our evaluation before the car went back on the transporter. Despite the wet roads and bit of wheelspin the transmission was the biggest transformation with how much quicker the shifts are executed. The power delivery also seems much more consistent where before the car didn’t seem to drop a gear when needed or the motor just felt sluggish at times.
A Stillen supercharged 370Z.
At first I raised an eyebrow to the crushed airfilter on this Q50 but apparently this car is just shy of 500hp. For an early development car the owner has to be pleased.
The UpRev turbo Titan. They had their V-cam installed which made the truck sound like a hotrod.
