VFE x Hex Tuning presents the World Premiere of the Ultimate Cold Air Intake and Tune

Hex Tuning, the sole provider of supercharger software for VF-Engineering, has enhanced the E46 M3 ECU software in combination with a renewed VF-Engineering Cold Air Intake (CAI) for the Ultimate intake and tune package yielding unprecedented horsepower and performance gains.

Hex Tuning software
For the past 12 months, Hex Tuning and VF engineers have been developing and testing on the street and VFE's in-house Mustang MD500-AWD chassis dyno resulting in a distinctly noticeable increase in throttle response and power. Various enhancements include comprehensive Vanos re-calibration for aggressive intake and exhaust camshaft timing and effective cylinder filling.

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.

VF-Engineering CAI
A MAF-less intake is used to refine the throttle response in all environments and reduce power controls by the overly conservative factory calibration. Peak gains of 35whp and 25wtq have been measured when used in combination with the VF intake and performance exhaust.

The cold-air feed tube prevents hydro-lock exposure and channels air directly to the airbox. Using a large multi-layer filter media, optimum airflow is maintained while providing 99% filtration.

Data and Features

Peak gains: 35whp and 25wtq on a Mustang 4WD load dyno with 91 octane.

Update from the East Coast:

Note that the customer has the following:

Headers, no cats
VF Intake, no MAF
Bimmerworld Race Exhaust

This was a street car but converted to a racecar a few years ago. Engine has over 112,000 original miles.

This car originally had a ESS Supercharger (and the owner raced in NASA GTS5). It has since been removed and is now NA. With some more de-tuning with VF, we're hoping the car will be averaging around 300rwhp since the 318rwhp put the car in GTS4.

Fortunately, with the Hex-Flash dongle, we will be able to switch from GTS3 trim to Enduro trim (no hp limitation) within minutes. Having the ability to work with VF on this customer's requirements is a big plus. How many tuners get asked to make LESS power? Not many, I'm guessing.
