Default Is Ecu boon or burden ?

We should seriously contemplate whether ECU is a boon or a burden? Because many times it gives problems than any advantage to non-ecu vehicles. An ecu means antoher part to be taken care of.

The same can be debated abt the pervasiveness of computers in our lives.

Do they have disadvantages? Definitely. Do they have advantages? Absolutely.

Since I'm very interested in the increasing the number of jobs(multi-tasking), quality of a job done, reducing the least amount of time to do it right, and the advantages outweight the disadvantages I'd prefer automated computing all the way.

Not much difference to a situation in a car, is it?

its advantage all the way, be it power, FE or better pollution control ECU has helped alot.

again if you look at the number of ecu complaints its minuscule compared to say a carburation problem in real life scenario.

then the icing in the cake.. piggy back ecu's great convenience in moding

Its surely a boon as per me.

What about the tricky carburetor which it replaces & which needed tuning more often than the ECU.

Of course ECU is boon. As pointed out by Jaggu ECU helps in achieving better FE, Power and lets not forget pollution control.

As for taking care of ECU unless it has been tampered with or engine has done excessive modification and on very rare occasions like floods in Mumbai you really don't have to worry about it.

One day, not too long in the future, this same ECU will be driving the entire car

ECU is definitely a boon. Think about a lot of technology in vogue these days, how would you achieve some of those without ECU (Say Cylinder deactivation).

ECU does tuning on the move rather than one having to adjust with the screw driver (or like in some high-end old cars with knobs/levers for advance/retard or rich/lean). Maximum mechanics that work on carburetted cars in India dont have the knowledge to do it right. They just do something based on what their trainers have told them who got it from their trainers and successively there has been an information loss. (You cant expect a mechanic to read air-fuel curves). So with an ECU you car is always tuned right provided the peripherals are clean and working fine.

No we shouldnt even contemplate ..
ECU's arent that bad, they dont create problems unless we go and mess with them.

99.99 % problems I've heard about ECU's are not even ECU related, its just lack of info regarding ECU which has led to this...
Ive heard of people blaming ECU from knocking,poor performance,bad mileage to engine missing etc etc..

Just out of curiosity how much care or what care do you take to mantain your ECU.. ECU is not meant to be serviced/mantained.

Does a 2000 santro got an ecu ? An acquaintance recently was telling about his santro s' ecu complaint and it cost him 25000 rs.

ECU's are definitely a boon for those who know how to use them and a nightmare for those who think they CAN tinker with them not knowing head or tail of it. Prime example being the advantage an ECU gave incase of Carb & MPFI Zen & Esteem. Check out the figures yourselves.

ECU's are good, no doubt - but they have undesirable side effects. For example, the ECU keeps the engine spinning at a particular rpm, though you are not applying throttle and so the car will continue moving at a particular speed no matter what. It can be frustrating in slow moving traffic, when you let your clutch out and your car jumps to kiss the bumper of the car in front and you have to brake to keep it in check.

Ok, but 'using' an ecu makes less sense. Because problems arising out of an ecu is not just because of tampering it. And about FE improvement with an ecu, it is not as great as it is hyped.

Carb Esteem - 65 PS and 14 kMPL = lot of vibrations on cold start in winters
ECU / MPFi Esteem - 87 PS and 14 KMPL = remains the same all round the year

What say ???
