Finally got a usb to serial adapter and hooked up the Innovate SCG-1 to the laptop to data log. So glad that I did here is what I found. The SCG-1 is capable of data logging three parameters, RPM, Boost, Wideband, and Wastegate Duty Cycle.
On the previous settings the car was WAYY to rich at WOT. I started from scratch and turned off the boost controller which makes the gate run straight off spring pressure, which is currently at a low 8 psi.
Right off the bat I realized how rich it was, pulled over to view the logs and it was pegged at 9.78:1 at WOT. The SAFC was set already to -15%. I leaned it out to -25% from 4k above and finally got the tune into the mid 11's. Leaning the tune out to mid 11's significantly improved the butt dyno. I could instantly feel the car pulling harder to the end of redline.
After a few pulls I noticed a bright red newer mustang in my rear view so I set the car to 60mph on the cruise and waited patiently I figured why not see if it's a shelby gt500. Sure enough as it pulls up next to me the plates read "LOL LSX" and Shelby gt500 on the rear. I paced him for a bit and then decided to see if he was willing run.
I briefly sounded off the wastegate dump next to his window
to see if he was interested and he replied with a supercharger whine rev down
. He started slowly bringing the speed down next to me as we backed up traffic and downshifted to 2nd at about 5k rpm and held on as my adrenaline started flowing. I glanced over and waved my hands forward signaling to roll into WOT and we went for it
. The car ripped through 2nd
, grabbed 3rd "cringing" , and watched him pull about 2 cars away through 3rd gear and shut it down. I threw the thumbs up
and he had a big grin on his face
and we parted ways.
While I didn't win I felt pretty stoked about hanging with a shelby GT500 at 8psi. On the way home I cruised for a bit and then started turning the wastegate duty cycle up
. Ended the night with 28% duty cycle achieving 16-17 psi and 11.0:1 across the RPM band. It tends to lean out slightly toward the end of each pull to mid 11's so I was happy with setting the tune to low 11's. At 16-17psi the car screams and feels awesome! Can't wait to get some Meth / Water injection on the car and turn it up to 20+ and run into the GT500 again
. I still need to properly boost leak test the car to make sure it's leak free. I'm sure there is more power to be made and I also have a 4" Raceready electric cutout ready to go on the midpipe. The Fujisubo catback isn't the highest flowing system so the 4" cutout should free up some lost horsepower.
My buddy owns a stage 2 upgraded supercharger pulley B8 Audi S4. It should be easily a high 117-120mph trapping car. I'll report back with results racing him!
