Red Headed Stepchild-75 Swinger LSX Swap
After the drag and drive i narrowed down some boost leaks, as well as got some info to hopefully help me with the sync loss error on my car. I made some adjustments and decided to catch the test and tune at pacific raceways this past Friday night.
My son was awesome enough to come along and give me a hand, and luckily he did because i got one of my all time favorite pictures of him and I together after the last pass.
Pass one i tried something different and left in 2nd gear with more RPM to see if i could get it to build a little more boost off the line with a high RPM limiter on the launch. It didnt get anymore boost on the 2 step but still went 1.4 to the 60 foot leaving in second gear and was enough to hurt a full bolt on/e85 tuned hellcats feelings. The crank sync error cam in again and it died off and i had to let off and get back in it to run out the 1/4 mile and still managed a high 9 second 1/4. My data log didn't start during that pass so i had nothing to go off of data wise.
At that point i said to hell with it and brought the launch rpm down a little to where i knew the car liked it leaving in 1st gear and left everything else the same. Which turned out awesome as the car went A to B without issue for the first time in a long time and I went a new pb for this new setup at 8.9 at 150mph. Turns out it ran that on only 12.5 psi of boost down track(further boost leak testing needed) with a new PB as well for 1.25 60 foot.
That got the heart pumping and I cant wait to keep moving forward on this setup and really lean on it. If the error continues to pop up ill switch it to a external crank trigger or to a 58x4x sensor setup like my previous motor had and hopefully alleviate all the issues and really get this thing tuned up this fall.
