At - Home HP numbers?
Anyone know the best way to see roughly how much power the car puts out? Maybe an app? OBD2 connector? Trying to see some differences between 91 ACN and E85 without paying the lump sum of cash for a dyno tune.

Datalogging with BM3 has a channel called "TorqueAtClutch(actual)." I have no idea how accurate it really is.. But theoretically, you can use the ft-lbs provided on the log, with the RPMS at the same time, and calculate horsepower using a calculator like this: https://spicerparts.com/calculators/...que-calculator
Could be wildly off though. Only real way is by getting the car up on a dyno. |

Load down Virtual dyno and put in your numbers and go out and drive. It is surprisingly accurate when you compare to a real dyno. Difference were 16 hp on my car when i compared to the Dynojet.
