This morning I went ahead and uploaded the new Phearable 1.5R tune. I've had it for a while but I've hesitated to flash it due to some reports of high knock control from a few users.
The setup
1.5R tune; BBG set to 18 in 1st; AVSA (light)
Gas used: Sunoco 93 Ultra
Ambient temps: 85° and humid
I do a loop of a little over an hour. About 30% city, 70% highway. All testing was done using the 20 psi Map 2.
The test
The first 25 minutes was me basically just taking it easy and looking at some parameters. The last half hour plus I pushed it a bit. I was able to do several aggressive moves, including a 70-110 pull, a number of aggressive highway passing moves and some low speed city lane changes.
I also drive in an area with many, many hills which is a nice test of knock control stability.
My observations
I think my biggest takeaway and surprise was just how stable knock control was. It stayed glued to .49 the ENTIRE test loop drive. Impressive. After the 1+ hour of driving, LTFT was at -2. Again, really impressive.
By the seat of the pants, it felt like the regular 1.5 ... PLUS. It's still just as smooth (maybe smoother) than the regular 1.5 tune. Power-wise there was a touch more pull when I put my foot into it. And the real icing on the cake was not seeing knock control rise artificially at high rpm.
One other surprise. Seeing 42 mpg on the trip computer at the end of the drive.
Conclusion
This is the tune to buy if you have access to quality 93 octane gas (or even quality 91 topped off with a splash of E85). It's smooth as silk, yet potent.
