Chipping.

 


When Chip programmers reprogram a chip for a new car their objective is to make it better than the original. Torque is the fundamental item for improvement, and increases are usually in the order of 10% on normally aspirated cars.
The engine is run up on the rolling road with diagnostic equipment monitoring the ignition timing and fuelling.

The ignition timing is remapped to create a new advance curve, the fuel map is modified to further optimise power output on full power and to improve throttle response without destroying economy on part throttle.

 

 

  On a normally aspirated engine these adjustments will give up to 10% more power. This increase of full throttle, coupled with the changes we make to part throttle, make the car much more lively and responsive, and require less gear changing. Annoying traits that sometimes occur on ECU controlled cars, such as over-run cut off hesitation and poor part throttle response, are eradicated by the remapped chip.

On turbocharged engines the manufacturers boost limit is increased allowing the boost pressure to be raised. The remapped chip matches the ignition timing and fuelling to match the modified boost pressure, allowing impressive gains of 35% more power and torque on some models. Whilst power gains may be impressive, most chip manufacturers have maintained safe parameters in their remapping to ensure long term reliability is retained.

Performance chips are designed to enhance the performance of standard cars simply by replacing the original chip. No other tuning is required. However for even more performance your Performance chip can be fine tuned to maximise the benefits of other tuning components such as a performance exhaust, free flow air filter and even internal modifications such as a performance cam and modified head.

Problems ;

Adrian Cash recently wrote to me regarding his Collins chip ;

Caleb, the problem is that the chip so I’ve found out yesterday is a group n rally car set up. This is fine for flat out racing but the car is running rough as it is set up ready for when you nail the throttle, ok it goes like stink when you accelerate but the nice banging and crackling and 3 foot flames are caused by the ECU telling the car to continue squirting neat fuel into the engine which is why its using so much fuel. The car is going to the garage in warrington near Chester on Monday and is having the chip removed and the hks evc .... 4-boost controller fitted instead, this is the dog’s bollocks apparently and has loads of different settings, especially one for economy on a long run. They say I will not need to do anything with the intercooler as it will only be running 1 bar 15psi.
