Can you tune an E46 M3?

Although E46 M3s are famed for their handling, tuning can improve things hugely.

How much does it cost to tune an E46 M3?

E46 m3 tuning Mafless tune from $1,450. This is designed for cars with custom air intakes where fitting the factory air flow meter becomes difficult. Includes an air temp sensor wired and fitted.

How do I get more power out of my E46 M3?

To boost power, the plastic airbox can be replaced with the S54B32HP carbon fiber airbox that came on the E46 M3 CSL. The CSL style airbox eliminates the MAF sensor, so it also requires special MAF-less tuning often called “Alpha-N”. An air box like this could net another 15-20 WHP.

Can you tune a BMW M3?

The modified M3 has a reprogrammed ECU and nothing else. Wrench Studios was able to crack the M3’s ECU to tune it, wringing more power out the powertrain. It has no other modifications other than the ECU tune, which takes the stock output up to 600 hp (447 kW) and 516 pound-feet (700 Newton-meter) of torque.

How much horsepower does a E46 M3 have?

333 hp
The E46 M3 came with a 3.2 liter inline-six engine developing 333 hp and 262 lb-ft of torque. It could hit 0-60 in 5.1 seconds and had an electronically controlled top speed of 155 mph.

What is an alpha n tune?

Alpha-N is a tuning strategy that makes the file unique to that car and its modifications. The car must be tuned on the dyno to dial in your engine and get the most horsepower and torque. The standard ECU programming relies on sensors like the HFM to set its tuning.

How much HP can the S55 engine handle?

The stock S55 fueling is able to keep up with 100% E85 up to roughly 600whp. Though, it is important to pay attention to AFR’s. You must also have the appropriate tune to keep up with the demanding fuel flow. A JB4 alone can handle up to 30% E85.

How much power can a S55 engine handle?

A “safe” upper limit for the S55 stock turbos lies in the 25-26psi ballpark. Push too far beyond 26psi and the turbos quickly exceed their efficiency range. Longevity is another concern when pushing turbos too far. In general, the stock turbos should hold up well anywhere under 25-26psi.

Are E46 fast?

The M3 seems to be effortlessly reaching 155 mph (250 kph) too, and there’s potential for even more. The highest speed it reaches in this video is around 168 mph (270 kph) with the engine being just under 8,000 rpm….Gallery: G-Power tunes the BMW M3 E46 to 450 PS.

What is Alpha N fuel injection?

In Alpha-N mode, the system uses Throttle Position to measure the load on the engine. It then uses the throttle position and RPM to identify a cell in a 3D table that fuels the engine at that specific Load and RPM.

How does speed density work?

Speed density systems do their work first by measuring the temperature of the inlet air and then the manifold pressure via a manifold air pressure sensor, or MAP sensor. They then calculate a density of air with which the ECU can calculate how much fuel it needs.

Is the S55 better than the B58?

An S55 powered M3 can be found for roughly $10,000 more than a B58 car. The B58 is a great engine, but the S55 is better. Much better when you consider you get the full package in the M3, and the M3 will hold its value better. For that reason, the B58 scores the worst value rating.
