TUNE-UPMAXIMISINGYour ModificationsWith the technology available these days, fine-tuning your car will nolonger run up hefty bills.With your three basic modifications,namely intake, header and exhaustin place, many then ponder, what’snext. To be honest, the road downperformance modifications is endlessand this doesn’t even include handlingupgrades. However, after having yourbasic modifications covered, you canlook towards treating your car to asimple tuning session to maximizethe potential of the modifications.In a nutshell, tuning of the car’s ECUwould involve altering various aspectsof the engine’s operation. By performingsuch a process, one would be able tocontrol variables such as fuel injectorand ignition timing. The extent of suchcontrol would ultimately be determinedby the tuner’s capabilities as well asthe type of ECU involved. Dependingon the extent of modification done,a basic reflash of the factory ECUor an air-fuel controller may suffice.For heavily souped up engines, astand-alone ECU which replaces thefactory unit may be the only way out.For the masses, a basic air-fuelcontroller would serve as a great toolin gaining that few extra horses. Notonly does it not cost an arm and aleg, such gadgets can also be easilypurchased and installed at mostworkshops. A universal harness wouldfurther allow it to be used on mostcars, enabling you to enjoy its benefitseven if you decide to change your ride.A car’s factory ECU is oftenprogrammed to calculate the properratio of fuel to air for an unmodifiedengine. However, when a high-flow filteris introduced, the amount of air in thecombustion chambers would increaseand hence additional fuel is required foroptimal combustion. This is where anair-fuel controller would come in handy.These air-fuel controllers are oftenconsidered multifunctional subcomputersthat allow the tuner totap onto the car’s factory ECU andreceive various sensors’ readings. Withsuch readings in place, one wouldthen be able to accurately diagnoseif there is any lack or excess of fuelpresent and make the appropriatechanges. Such compensationswill increase the drivability of thecar as well as bring out the best inthe accompanying modifications.Most air-fuel controllers also boast auseful external display which showsengine statistics such as RPM andthrottle load. These displays alsoallow your tuner to work their magicon your car but unless blowingcash on a new engine is smallchange to you, we strongly adviseagainst making such adjustmentsby yourself. Leave such stuff to yourcompetent tuner and enjoy the ride.32 JULY 2011
