4x4 PerformanceImprove Both Your 4x4’s Performance And Economy A piggyback computer chip can do much to improve the performance of a turbo diesel 4x4. It may not in all cases turn a slow vehicle in to a 4x4 performance vehicle, but it can do a great deal to alleviate that all-too-familiar “overtaking angst”, when many 4x4s simply seem breathless, endangering their passengers by having to spend too much time in the overtaking lane due to a lack of power. A piggyback computer chip intercepts the signals from the engine's ECU and adapts them to achieve different ends. For example, it can increase fuelling, raise turbo boost pressure and manipulate devices such as variable valve timing and variable intake manifold mechanisms – which are all electronically controlled – to yield significantly more power. The best of these chips offer several “maps” and the full-throttle map would typically be aggressively programmed for the most power in preference to economy. However, the “economy” map would be programmed for maximum economy at part-throttle driving. Unichip is your car and 4x4 performance specialist and we can help you get the best power and economy out of your 4x4 today. For more information on how we can help, contact us.
