I appreciate the response and the invitation to be welcomed back in the future. As far as the boost reading, it was measured initially with a mechanical boost gauge. After inquiring I checked everything over multiple times. The car felt good otherwise. If I never installed the gauge I would have assumed a much higher reading based on the benefits of upgrading to a 3bar map sensor and methonal. When doing my own research and learning about a 3bar map sensor it was an educated assumption that if my car was tuned for a 3bar sensor I would be using more boost. If not then why would my car run rough if tuned for a 3bar if I left the 2bar installed if in fact boost wasnt increased? Without boost being increased why would I need a 3bar? That was my question and I was hit with vague answers and then a shot in the dark about the proposition of taking the accountability of the company into question based on Ethan's response. It was never about that. And with Meth, safely increase boost/prevent detonation and cool the intake charge...then why not increase boost? It was not making sense to me. My intention for purchasing each mod was for the sole purpose of utilizing each for what they were manufactured to do.
I ditched the mechanical gauge and installed an Aeroforce Interceptor Scan Gauge hooked directly to my OBD port. Same readings. And then lastly some datalogs of the tune confirming again the same readings. My car is healthy and running strong. Its being pushed but not to the extent of engine or drivetrain imminent failure. Probably the best benefit of datalogging is the ability to steer clear of catastrophic failures since the health of the car is recorded for review. Nothing is bulletproof but its pretty safe.
I'm very happy with my tuner. If I'm looking to push my car I wouldnt trust anyone else. Your tunes are safe and reliable and fast, theres no denying that but for my needs it was too safe and not fast enough.
At the end of the day, we can always set up someone's tune for more boost so long as they understand we keep things within a safety net for very specific reasons. Going outside of this window can, but not always, result in failure. If they know, and truly understand this then we can step on it more. No one out there has more control over what an EcoBoost does than us, to that end, it also means no one can do something we aren't capable of, but it does circle back to just because we can doesn't mean we should.
I think that many people might misunderstand, or maybe don't know why we do the things we do. in around 2007 or so we started developing our own software for certain vehicles. This was done out of need as there was often errors, or missing items in commercially available solutions. We found ourselves often having to chase issues caused by the software rather than focus on being able to calibrate things properly. Since we were having to chase down errors to work around them, we felt it was best to start taking the time to make things for our own exclusive use and knowledge. Since those days we have greatly expanded our coverage, understanding, and capability, especially in the world of EcoBoost. This is why we have so often been first to market, sometimes offering tuning solutions for years before anyone else, and have offered solutions that no one offers today (like calibration for our fuel pumps, flex fuel on certain applications, etc). This also allowed us to ensure that we are calibrating these vehicles while utilizing the OEM control logic, rather than brute forcing it to do what we want. One key to this is ensuring that the data being reviewed is proper. This means that it has to be in the proper values in regards to the PCM. So when people datalog, and they talk about Boost in PSI, or KPA in any value other than in-Hg, it's not going to be accurate. On these cars, every bit of pressure is measured this way, and the only way to properly understand and control these is if you log, and calibrate using this unit since it's the only unit that doesn't get a conversion, or offset added to it. So, if you look at the attached log you can see what we mean. You see that the desired pressure is 62, this is an absolute value that has not had the baro value removed. So if baro is 30, then it's got a desired pressure of 32 in-Hg above atmospheric pressure. This roughly translates to 15.7 PSI, no where near as low as the 11 PSI that is being referenced, but when you are logging the incorrect parameter, in the incorrect unit, this type of thing happens. But it also shows that we can command pressures higher than our standard tuning.
Fast forward to what we offer now, often people have talked about logging, and wanting the capability to log and send those logs to us. Up until the release of our MyCalibrator Touch, we had always said no. Mostly for the reasons above, incorrect data items, incorrect units, and often, far too slow of a data sample rate to be of any real use. Well, as we build out the function on the MyCalibrator Touch this will not be a problem anymore. We will be able to review, and trust it. Currently it's still in BETA, but it's close to being a stable release so it can be used more for actual tune revisions, and for those who want to log for peace of mind.
Oh, and on the 3-bar, it's always been a safety thing. Because if you peg the stock 2-bar by .1 in-Hg, or 100 it has no idea, and doesn't know how much to react to get boost back under control.
