HEX TUNING ECU SOFTWARE UPGRADE and Cold-Air Intake
(gain approx 30-35hp/20-25tq) 295whp and 236wtq
ECU software for the BMW M3 was enhanced by Hex Tuning and VF engineers resulting in a noticeable increase in throttle response and power. Various enhancements included comprehensive Vanos re-calibration for aggressive intake and exhaust camshaft timing and effective cylinder filling.
This calibration was scientifically developed/tested and measured on a Mustang MD500-AWD chassis dyno using 91 octane. The top speed limiter was removed and combined with refined ignition, fuel and camshaft calibration.
A MAF-less configuration is used to refine the throttle response in all environments and reduce power controls by the overly conservative factory calibration. This software is well suited with MAF-less cold air intakes such as the VF-Engineering cold air intake system for the M3. Peak gains of 35whp and 25wtq have been measured when used in combination with the VF intake and performance exhaust.
Worldwide models of the M3 are applicable and the software is user programmable with the use of the Hex Flash programming cable included. The Hex Flash cable works in conjunction with a laptop and is used to read and write software from/to the vehicles computer (ECU). This allows the user to revert to original programming anytime they wish.
