Iconic black cabs could get fuel economy boost

Received 23rd April 2010

Buckingham-based technicians believe they could make London’s iconic black cabs both more powerful and more fuel efficient.

The Superchips company took the most recent version of the taxi cab, the LT1 TX4, which is powered by a 2.5litre, four cylinder turbo diesel engine, and aimed to boost both its driveability and economy. They analysed the vehicle’s Bosch EDC16 ECU and found several optimisation opportunities that enabled the company to fine tune the map settings to remove any inbuilt compromises while also boosting performance.

With their remap, the LT1 TX4 saw its torque vastly lifted from a measured 265Nm at 2,622rpm to a maximum of 339Nm at 2,352rpm. Power gains were also impressive with the car producing a measured 103bhp at 3,059rpm previously but with the Superchips remap it leapt to 3,479rpm.

Of particular interest to green car fans however, is that not only did the Superchips upgrade boost the performance of the vehicle but it also helped its fuel economy with fuel consumption gains in the order of 10 per cent.

Superchips is now offering the upgrade in a matter of minutes at its dealerships in the UK priced at £445. The conversion comes with a full customer service guarantee and a warranty.

How many miles would you have to drive to recover the £445 outlay?

Grandad,

Is an extra 10% on an already pi** poor mpg ratio something to shout about?

If the claims are achievable, then yes, it is something to shout about.

My brother who lives in your neck of the woods, spends £200-£250 on derv each week, so if true, £20+ pw saving.

He'd have his money back within 6 months.

My 105 BHP skoda is chipped to 130 BHP and I am getting an extra 10 mpg, its also a lot smother and less gear changes

my mondeo 130ps (standard) is averaging 49mpg on a standard 850 mile school week, did a day out over easter, 303 miles, 54mpg

id like a remap and decat to up the torque but its £300 for the 2, not sure id see it back

ive also gone onto BP ultimate derv for a few tankfulls

How much extra did the Insurance company slap on your premium skip?
Ive toyed with doing similar..

Is'nt that stuff so expensive that its almost a collectors item..

You drive a skoda? why haven't you mentioned it before?

I meant on the vehicle as a whole, not with the add on product.

In other words should we all be shouting that a vehicle does 22mpg rather than 20mpg.

Shouldn't we be saying any vehicle that does less than 35mpg isn't one that we should be driving in the first place.

well, if you dont tell em...


its not an obvious modification and would require a diagnostic to read what firmware was installed on the ECU/PCM

you can tune for power (BHP) or economy (Torque), the external "boxes" are not well thought of generally.

a remap is basically tuning the ECU/PCM to your vehicle, whereas a bog standard unit is "one size fits all"

Possibly because of the sh*t gearboxes

Insurance was informed sent them the print out no extra charge


What planet are you on or from there a very nice picture on here

Had mine done a few years ago, took it from 130BHP to 145BHP. Made quite a bit of difference.

mines gonna go in for a diesel service (injectors/recode,etc) at a delphi agent and then for a belt and tensioner/bottom pulley and service, if its hunk dory then it will get a remap and decat, cant see the mpg improving much tho


ill buy a skoda superb/VW passat next, or a saab TDi
