I received my MyCal and loaded the Stage 4+. I was overall impressed with the actual device and how it connects to the Internet to get your tunes. It does take 24-48 hours to actually get them once you send them the required car information so you need to have a little patience but all in all it was a smooth experience.
I had baselined the SCT stage 4 from Livernois and posted a graph of a scan in a previous post (will repost here). I am still JUST comparing them and for the record the scan I did was RIGHT after I flashed it (I let it warm up just like I did the SCT scan and went the same distance. Scans were run on the exact same stretch of road. Temperature was 6 degrees warmer for the MyCal run).
My initial impressions are positive. It definitely builds way more boost (up to 3 lbs more than the SCT tune) however they also lowered the timing so a bit of a tradeoff...There is still quite a few more comparisons that could be done but based on timings it appears that I gained a full 1/10th from 0-100 with the MyCal. It does appear that I have more Knock with the MyCal tune - at least I think - Forscan shows negative value for knock which I think means it is taking away timing? Not positive on that one. That said it only peaked at 1.67 degrees so I don't think that is horrible.
It also (in my opinion) shifts better. The dreaded downshift clunk at 70-80 is gone which I am very happy about. It does shift a little smoother but I consider that a good thing. Your opinion may vary.
What remains to be seen is how the car "Learns" the tune and if it adjusts things back down or not. I will be very interested in seeing what happens and will scan again after I have put some mileage on the tune.
It does pull stronger up top...the real test will be when I race my own motorcycle (VTX 1800) which with the SCT tune was EXACTLY as fast as the car. To the point of where I could reach over and high five the driver of my car while I was on my bike. In theory I should be able to beat the bike now. Will report back.
The first graph is the SCT...the second the MyCal.
