Dyno pulls were in fourth gear so maximum RPM and power is reached prior to hitting the OEM speed limiter. Because of this, all measurements are apples to apples but will be low. Apparently, fifth gear, is 1:1 but again the vehicle would not achieve full power because the car would never reach redline (max rpm) in Bypass and DINAN modes. The values below are at the wheels.
DINAN HARNESS INSTALLED:
Dinan Bypass Mode* 447 HP 372 FT-LBS
Dinan Bypass Mode N.A.
Dinan Stage 1, first pull, 477 HP 401 FT-LBS
Dinan Stage 1, second pull, 477 HP 387 FT-LBS
Dinan Stage 2, first pull, 480 HP 389 FT-LBS *****THIS VIDEO*****
Dinan Stage 2, second pull, 482 HP 391 FT-LBS
DINAN HARNESS REMOVED:
OEM Stock Tune* 499HP 468 FT-LBS
OEM Stock Tune* 512 HP 465 FT-LBS
Tuning Tech Stage 1, first pull, 629 HP 615 FT-LBS
Tuning Tech Stage 1, second pull, 613 HP 590 FT-LBS
*The deltas in these numbers are eye opening to say the least. I fully expected Dinan Bypass and OEM Stock Tune to have close to equal values. Frank Smith knows Steve Dinan and respects his work and products. He said very few of his products have this type of an outcome and that most are GREAT! Essentially, certain products (not just DINAN) do not mesh well with certain BMW DMEs due to speed of the master (US passenger side) and slave (US driver side) DMEs. Frank has seen this issue before and that's why he suggested we do the extra pulls with the harness removed and running the stock tune before loading his tune. He is honest and does not want to falsely indicate a huge delta from the DINAN Bypass Mode vs. his Stage 1 tune. He wants to show a true OEM Stock Tune vs. Tuning Tech Stage 1 Tune.
I give Frank a lot of credit for doing this in an industry that is not always honest and forthcoming.
