Taxi Driver Online

not really, they bolt in an ECU already programmed and off you go, the factory settings are "one size fits all" and are de-tuned to avoid possible failures, in other words, my 130ps engine could make 155ps but ford decided it wasnt going to, but later they made a 155ps version (same car/same engine)

All manufactures supply engines in basic tune to take account of people not servicing them and different fuels around the world, so a properly tuned engine is going to be better off if looked after
They even chip the TX range now

For point of reference the VM engine is detuned in TX4 Taxis (101 bhp) the very same VM engine is capable of over 130 bhp in other vehicles. This is down to 'tuning for the application in mind' thus it is never a case of Ecu' being tune for 'one size fits all'

I would argue that Taxis do not need extra power but we could all certainly gain for an increase in MPG.

Sorry Skippy, but that sounds like total nonsense to me. I have heard some waffle in my time time but your commments have made found new heights.

I cannot argue with what you say Sasha, but in general more power from the same cubic capacity engine will result to greater fuel economy, the reason for this maybe down to driver input.

I think you wrong, but who cares

i get 50mpg in summer, 46mpg in winter (urban cycle) and 55mpg on a long run in 5th (6th is poorer)

its torque that moves cars, not BHP


(BTW, can you tell me how long Ford take to tune an ECU into a vehicle on a rolling road at the factory?...)

I have no problems with being wrong but it may be helpful if I knew specifically where I am wrong?

The Mpg return you get are great , I only wish I could hit the same levels.

You are partially correct that it is torque that propels vehicles BUT Torque and Bhp go hand in hand with each other......there CANNOT BE ONE WITHOUT THE OTHER. One Fact I can tell you with motorbike engines is that no matter how you tune them the max torque vs hp curve will ALWAYS peak at 5,750rpm. After that the torque figures will fall even though the hp figures may still be rising. So in light of this a spinning engine always has the ability to go faster well past the max torque figure has been achieved.

As for your question regarding tuning an ecu to a vehicle , Ford will spend too much time to mention on ecu and rolling road time whilst developing a new engine. BUT once the engine is fully tested and the ecu is set up then a blank ecu will be put into X model vehicle, it will then be given codes and flashed with the apropriate parameters of information.


I hope this answers your question.
