Ecu Remapping Vs Chip! (Performance Tuning)

ECU

Customers oftentimes inquire conditions they should opt for an ECU remap, or a functioning chip, when trying to increment engine performance. I similar to intend I give them a good informed response, too therefore I idea I would portion my response alongside you.

To commence alongside i of the questions you lot may accept is. 'If ECU Remapping or chipping is too therefore much better, why don't manufactures include it on the motorcar equally standard?'

Well the best response for this is that manufactures accept to ensure their cars volition perform good too come across emissions standards inwards countries all over the world. The biggest employment is the climate conditions modify where always you lot are inwards the world. Things similar humidity, altitude and temperature brand a massive departure to the agency an engine runs and consumes fuel.

So the manufactures accept to brand a decision  Go for all out functioning nether for certain climate conditions or brand a decent performing motorcar across many different climates. The response is normally the later on and manufactures come upwardly to a compromise. 

The affair is though if you lot know the climate too operating conditions of the engine, it is possible to achieve better functioning too fuel economy.

So which is ameliorate ECU remapping or functioning chips. To empathise the response nosotros get-go bespeak to expect at what each on does.

ECU Remapping  is all almost modify the software within of the ECU. This is achieved by either writing your ain software for the cars ECU, or to a greater extent than commonly changing the manufactures software.

Performance chips on the other mitt lucifer inwards betwixt the engines sensors too actuators, altering the information that the ECU either receives or sends.

An representative of what a functioning fleck does is this:

Performance Chip Operation

So you lot tin lav watch the fuel pressure level is at in i lawsuit ii bar higher than what it should be.

This is the major depict dorsum for Performance chips. This added pressure level increases vesture too tear on components (Injectors too pressure level regulator).

An ECU Remap on the other hand, is far to a greater extent than fine tuned. Fuel delivery for representative tin lav survive adjusted to suit air temperature or humidity due to the fact that extra humidity volition give the axe to a greater extent than oxygen from the engines cylinders.

To survive honest cost isn't actually a cistron when comparison these methods of tuning. H5N1 BMW X5 functioning fleck costs almost £395 for a skillful character one, whereas an ECU Remap for the same vehicle is to a greater extent than or less £350 for a good written remap.

You tin lav also achieve similar functioning too fuel economic scheme using either method.

It is a representative of personal preference and available for your car, equally non every motorcar is remap-able too non every motorcar has a functioning fleck available.

If i had to guide though i would become for a good written ECU Remap every time because of the fact that functioning chips tin lav crusade an increased vesture charge per unit of measurement on its associated components.

What are your experiences? I honey to take away heed almost them, instruct out me a comment bellow.
