REMAPPING??
CAN SOEMONE EXPLAIN WHAT REMAPPING IS AND IF DONE DOES THE LIFE SPAN OF YOUR ENGINE SUFFER / MPG ETC
Re: REMAPPING??
What is re-chipping?
The most difficult concept to grasp for most people is that re-chipping is merely engine tuning, albeit that it's being done electronically rather than mechanically (as in the old days of carburetters and distributors). A chip is simply an electronic storage device which is located on a circuit board inside the E.C.U.(the Engine Control Unit). The chip contains values in a binary form which the E.C.U's main processor (another device on the same circuit board) can understand and use to control the engine.
Each value inside the chip is held in its own separate position (known as an 'address'), and
In order to meet the stringent requirements, engines are virtually detuned to pass the test. As a result the car never performs as well as its mechanically controlled counterpart...
when a car is re-chipped, what we are basically doing is altering the values at the groups of addresses that control fuelling, ignition timing and on turbo engines, turbo boost. These are known as maps, hence the often-used term 're-mapping'. It is these maps which we massage in order to tune the engine.

Re: REMAPPING??
I was quoted £199 to have my ECU remapped, taking my 406 HDI 90 to 130bhp

Re: REMAPPING??
Before you consider remapping ask yourself what it is you want to achieve and why. If you want your car to get from A to B quicker then you may be wasting your time and money - your speed is determined by cameras and other road users. If you want to improve your fuel economy then try adjusting your driving style first.easthams1958 wrote:CAN SOEMONE EXPLAIN WHAT REMAPPING IS AND IF DONE DOES THE LIFE SPAN OF YOUR ENGINE SUFFER / MPG ETC
If you have a desire to use it on a race track you may gain a short term advantage if you are skillful enough to be able to use any extra power gained since the penalty on mechanical components could be dire unless you have specific data from the manufacturer that for example the connecting rods,cylinder head bolts, clutches and drivelines have sufficient margin for the extra loads imposed. In most turbo charged engines they have to govern the maximum amount of extra pressure that could be achieved and this is basically the only time remapping as any erstwhile benefit, normally aspirated engines need to be mechanically altered by skimming heads to increase compression or perhaps change the fuel to nitro with equal risk if other parts have no margin. It is not simply the need to comply with emissions it is the done by the manufacturer to present the best fuel economy within a power range that satisfies the product reliabilty for an acceptable life span and it is only after exhaustive testing that the manufacturer decides to set the mapping.
