It only takes 15-20 minutes to get it synced and loaded. Lunchtime!!

The realtime map stays active unless you disconnect the battery (or change/delete it with the AP). The AP only shows you which base map you have loaded, so if your realtime map is different than your base map, you won't see that.

Calculating flywheel HP from wheel HP (HP) is not at all accurate, and not worth doing. One of the real benefits of dynamometers is that they show WHP, which is all that really matters. You can have two identical cars (engine-wise), but due to different engine oil, tranny fluid, and even tire type and pressure, you can have different WHP numbers. WHP numbers are all that really matters.....in reality, only the wheel torque numbers across various rpms. HP is not a "real" measurement, it is a calculation of torque & rpm (work over time). Torque is "real". To prove the point, look at some common cars out there. An LGT 5MT with 250 rated flywheel HP can crack high 13s. Any Nissan with the 250-270 HP 3.6 V6 (depending on the model) is only good for mid 14s. Flywheel HP is irrelevant in these comparisons.

Keep something in mind. Peak HP numbers ain't worth a pile of steaming feces, IMNSHO. The torque curve from idle out to the peak is what gives you what you want. if you do a mod that increases torque throughout the rpm range, but adds nothing to the peak HP, you will like it better than one that lowers the torque curve and only adds peak HP (with torque way up on the top end). Keep in mind that HP is not "real", it is a derivative calculation based on torque over rpm. Torque is real. Increasing gross torque numbers is something that you can feel. Now, in an old RWD musclecar, you ca easily change the rear-end gearing to get back the low-midrange torque from puttng in a big cam, big-tube headers, or a too-big carb. Not the case on these or many other AWD/FWD cars.

If you do a search in this Forum, the two relevant tests for Stage 1 (for me, anyway) were: Cobb got 224 WHP on a Mustang Dyno Another private owner got 223.9 WHP on a 424x Dynojet. Cobb's dyno for Stage 2 were 237 WHP. No Stage 3, AFAIK. IIRC, stock LGT dyno 3s were clustered around 200 WHP.

What liability? The StreetTuner itself is a device that allows people to hose up their engines in any way that they see fit!!!! ;-) You're on your own with any roll-your-own software tool, whether you develop your own, or get a map from someone else.

Serial ports are so "1980s". I was surprised when I got mine.....I was expecting a USB as a standard.

The few times that I tried it, I have matched what the trip computer shows, so I don't mess with it anymore. I'm also pretty consistent on how I fuel the car. To answer the above question, yes.....it is the average mpg shown. For the first full tank after the AP map load, I got my lowest average mpg ever........19.5 Had something to do with my heavy right shoe!!

Yep. One thing that I have noticed on the LGT versus other cars that I've owned over the years is that there is a greater mileage difference between running at 70 mph versus 80 mph. Running at 79-80 as I tend to do, I get 24.7-25.4 mpg under good conditions. When I get the speeds to 70 or lower, I get in the upper 26 up to 27.3 range. My SWAG is that the turbo is more in play over 70 mph, which happens to be 3K rpm on the 5MT. This is with driver-only, but with the car packed with "stuff".

A buddy of mine just loaded the Eonomy map on his WRX last week. He has a long commute to work (mixed freeway/4-lane roads) and only saw 1 mpg over the Stage 1 93 octane base map he has loaded. I loaded the Stage 1 93 base map over a week ago, and I did my regular 490-mile drive to Indiana today. Traffic conditions change on each trip, as does my speed, but even looking at it pessimistically, my mileage is down no more than 1/2 mpg compared to the same trip in the past. It's also warmer today than it's been for the other times that I've driven it. I would call it a wash on mpg with the AP loaded......all dependent on your right foot!
