I've already written quite a few posts regarding the new TSP Stage 1 tune for the 1.5T non-Si (CVT). This one will be more detailed with some datalog screenshots to put some numbers to the words. When I first got he tune, my first impression was that it was smooth down low and potent up top. Felt like a more polished tune than the base KTuner tunes I was running. After more driving with it, I started to feel like the low end was a let down. It felt smooth but not as peppy (at part throttle) as my KTuner starter 21 with aggressive settings. I was even thinking of going back to the aggressive Starter 21. But I wanted to try one last test...
Today I did an extended test of the tune in nice cool weather (mid 60's), and the tune really woke up. For the most part it's been hot and humid here and we all know heat kills our turbo tunes. So, honestly, a lot of my earlier posts were based on a less than best case scenario.
Here are my impressions and findings from today's test in mild weather:
A couple observations to start things off. My fuel trims were excellent with this tune. LTFT pretty much stayed at around -2 or 3. Knock Control for the most part stayed near .49 and the highest I saw (after consecutive WOT runs) was .67, which fairly quickly dropped down. I was shocked how low my IAT's stayed. Seeing numbers those low numbers put a smile on my face and made my engine happy. Basically everything ran beautifully. This car loves cooler ambient temps.
OK, so let's talk about the actual test. I did a 35 minute loop. The great things was, going out 6AM on a Saturday, traffic was non-existent. I did a bunch of WOT pulls with Map 3 and tested out the 16.5 map as well. And I made a datalog of everything.
The 16.5 map is pretty much what our stock tune should have been. It's smooth but still offers a good amount of fun. At one point with me being the only car on the highway, I gunned it. I went from 70mph to 107mph before backing off. It felt great. Honestly this map is a big step up from stock and it would be more than enough power for many drivers. Here's a screen shot showing the moment my boost hit the target at WOT:
This run was done after I had already done a few pulls on Map 3. The IAT's are still nice and low considering how hard I had been pushing the car. Looking at the numbers, the tune appears to be targeting 17 psi and I hit 17.6 psi. This is a solid daily drive type tune. No complaints.
--------------------------------------------------------------------------------
Now let's go onto the star of the show. The full TSP Stage 1 Map 3 tune. I want to first say that even though the tune definitely feels softer down low than my aggressive Starter 21, it's still very good at lower engine speeds. It's just set up differently. The TSP tune is smooth down low, has a solid midrange and takes off like a scalded cat after 4,000 rpm.
During the test run, I did several WOT pulls with Map 3. The rush of power is phenomenal once it ramps up. On the datalog I'm posting below, I observed something interesting. I put the pedal to the metal and looked at the PSI and at first glance only saw 20 PSI. I had a WTF moment for a split second... "This is making less PSI than my KTuner 21 ???"
Well, my puzzled frown turned to a big grin in milliseconds. PSI kept building and building. Where she stops nobody knows...
So here it is. The screen shot of the moment my boost peaked out:
So, for those who have been wondering what the actual highest boost target is in Map 3, it appears to be at least 23 psi. I overshot that number and hit 26.3 psi... I had to double check my pants after that, but that's another story. I think the highest target I saw on the datalog was 23.1 but I swear it was still climbing before I backed off.
Needless to say, I was impressed. And even though I was driving my car EXTREMELY hard for a portion of my test loop I still averaged 34 mpg. Overall, this is a great tune and highly recommended.
Finally, even after 30 minutes of hard driving my numbers still looked fantastic. Gotta love 60 degree weather!
Note to self: Don't do testing with hot and humid weather.
