As some of you know, my M3 has had 2 ECU remaps done in the past 2 years; the latest being done by PS Tuning. Here are my thoughts and humble opinions on remaping:
The theory behind remaping is to alter the air-fuel ratio, ignition advancing or retarding depending on RPM, throttle position, air temp, etc...The key to a successful tune is how much area is there under the hp/torque-RPM graph, NOT how much the peak numbers are for power and torque. If you're looking for that in a tune, sorry it's the wrong way. Dealing with professional tuners can give you a great luxury; choosing how you want your power curve to look like :D This feature allowed me to shift my power band from low-end-to-high-mid range, which is ideal for daily driving, into mid-range-to-high-end corresponding to the car's racing characteristics. Honestly, driving other E46 M3s feels like an ordinary affair after remapping mine...It feels sad to know that this engine should've come like this from the factory! YOU...NEED...TO...TRY...IT! Period!
After the season was done, I always wanted to verify the other claimed benefit of remapping; i.e. fuel economy. Which I did during the past 2 weeks.
On two full tanks of 98-Octane fuel, and introducing 3-digit highway driving speeds, grid lock jams, city cruising, frequent sprints, frequent engine start ups, I'm glad to report that the car delivered a 505km range between fill ups on both occassions. That's with my enjoy-it driving style. Ofcourse, the car is fully maintained constantly at Falcons Garage and *** and this helps, but to think with all that power, speed, and madness the car could still attain such mileage is, to me, truly remarkable....
Recommendation:
Go for it! Remapping is the best money you will ever invest into your car. It's a shame OEM manufacturers leave TOO MUCH safety margins in their OEM maps, but hey, that's more ways for us to enjoy them cars ;)
Hope this helped...
