Engine remapping has turn out to be more and more widespread lately, as drivers turn out to be extra conversant in the little black containers that management their vehicles important capabilities, and extra conscious of the alternatives to ‘tweak’ the settings.
The method was once known as chipping, because it actually meant swapping a microchip in your automobile’s Digital Management Unit (ECU) with a modified model. These days the black artwork has superior to the purpose the place home-brewed engine remapping software program is accessible to obtain from numerous web teams for courageous and/or tech-savvy home-tuners who wish to experiment. We’d by no means advocate that route, as unsurprisingly there’s a big threat of inflicting costly engine harm if a remap just isn’t completed correctly.

So for most individuals an engine remap includes a visit to a neighborhood specialist who can overwrite your manufacturing unit engine settings by way of a laptop computer, or ordering a handheld gadget just like the Superchips Bluefin. This can be a DIY unit that plugs into your automobile’s Onboard Diagnostic Port (OBD) and can overwrite the engine map with an upgraded model in round 20 minutes – or revert to the usual manufacturing unit map simply as simply.
Different remapping techniques embrace the one produced by RaceChip which provides a small further ECU to the wiring loom and supplies distant management of a spread of engine map settings as you drive, both by a hard-wired rotary controller or wirelessly by way of a smartphone app. It could sound radical, however actually it’s little totally different in idea to the selectable drive mode settings supplied as a part of the spec by many automobile makers as of late.
Why trouble with a remap?
There are two major causes for wanting a remap, they usually’re known as energy and torque. When your automobile left the manufacturing unit there’s an excellent likelihood its efficiency was intentionally muted with the intention to meet product planning aims or financial system and effectivity targets.
As of late the facility and efficiency of most vehicles is restricted, not by any explicit mechanical issue, however by the software program working within the engine management unit (ECU).
Pc algorithms working behind the scenes whilst you’re driving a contemporary automobile have an effect on all types of parameters, comparable to ignition timing, air/gasoline ratio and turbocharging enhance stress.
So if you’d like larger efficiency and pulling energy out of your automobile, or alternatively when you’re in search of mpg enhancements, the primary place to look is the little black field underneath the bonnet. Right here at Auto Specific we obtain loads of emails asking recommendation about ECU software program modifications, and we have compiled this information to discover the professionals, cons and prices.
Chipping turbodiesel engines can improve financial system by seven to 10 per cent, as a result of it provides torque decrease down the rev vary. This implies the engine doesn’t need to work as exhausting as earlier than. It is these turbo diesel engines (usually referred to as TDI, HDi, CDTi relying on the producer) which are cornerstone of the automobile chipping trade as a result of an engine chip or software program improve can cheaply add a lot to the efficiency.
The claimed efficiency beneficial properties are sometimes eye-catching, and achievable for minimal outlay on even pretty mundane vehicles. For instance RaceChips have a spread of DIY upgrades for a 2007 Ford Mondeo 2.zero TDCI beginning with an additional 24bhp and 61Nm of torque for simply £129.
Spend £349 and also you get 37bhp, 89Nm and ‘good tuning’ by way of the app. Received a 2014 onwards-SEAT Leon? Superchips will add 19bhp and 36Nm to the 108bhp 1.2-litre TSI mannequin for round £350, and a fast search on-line reveals a mess of suppliers providing upgrades for all method of automobiles and producers.

Its technical director Jamie Turvey instructed us: “Remapping does put further pressure on an engine, however not a harmful quantity. We test rigorously that the temperatures and pressures our remaps put the engine by means of don’t exceed the suitable parameters.”
He added that almost all vehicles’ engines are constructed to supply extra efficiency than they really ship. “You discover producers launch a automobile with a set energy determine, however then over the lifetime of the mannequin they’ll introduce a number of facelifts and efficiency variations,” he defined.

“They don’t develop new engines for every new model: largely they restrict the efficiency of the sooner fashions after which provide slightly extra energy with every new version. We simply launch the optimum efficiency.”
Clearly, you want to inform your insurer of a remap. However you could be pleasantly shocked by its response, based on Turvey.
“Traditionally, insurers would run a mile from chipped vehicles,” he stated. “Some nonetheless will, however for probably the most half it’s very totally different as of late. Some will simply say ‘thanks for letting us know’; others may have a set charge.”

It’s also possible to pay to have your automobile examined on a rolling highway so you may see the impact any ECU remapping work has had on the engine’s energy and torque output. Round £300 would most likely get your automobile chipped and examined on this method and, alternatively, a lot of engine tunning corporations will provide a cellular service, becoming the chip at your private home or place of business – for a charge.
