Remapping vs chipping!!

The never ending debate and probably the most frequent question we receive is how we differ to chipping of a vehicle(especially turbo diesel vehicles) and why is remapping far safer?? We’ll touch on these issues with a little background of a daily occurrence of us removing chip systems to move clients onto a custom factory ECU Remap!!

Most clients have issues with a sluggish and confused gearbox with poor fuel consumption that don’t match the pump reading or even close, in fact the pump discrepancy with Chips are another massive factory we touch on!!

After removing the chip and remapping a van the Power, response and fuel efficiency all improve significantly while having smoother gear changes and less erratic downshifts Hilux vans especially are infamous for!!

Read on for more technical information regarding chips vs remapping!!

The reason for the poor results basically begin with the fact that the Chip systems splice into sensors and wiring and falsify readings to the ECU, thus fooling the factory ECU into not showing fault codes but also hiding all the adaptation and correction these ECU’S do every second of every day while the vehicle is running to keep these engines running as optimally as possible!!

These chips boost signal voltages and manipulate ECU feedback to push significantly higher fuel pressures and boost turbo pressures linearly through the full rev RPM range – higher boost pressure at higher RPM is where turbos fight to keep up the Air flow movement and ultimately cause the failure of most turbos!!

ECU Remapping employs Boost tapering for safe and engine specific boost peaks to tune the engine to its most ideal RPM where the volumetric efficiency is highest !!

– Firstly, the biggest issue with chips is the safety!!

– Negating of sensor readings to keep the van running without limp mode or faults being shown despite the obvious out of range readings the ECU would see from the Chip altering fuel and turbo pressures!! This can result in overheating and often does cause issues with melting/cracking pistons on many turbo diesel models!!

– Secondly, the turbo pressure being altered with voltages means you cannot boost taper and really get the vehicle  running in its most optimal low RPM where there’s no stress on turbo and these engines really thrive at these lower Rev ranges and also produce far better consumption at these revs!!

– Lastly, fuel efficiency savings being one of the most appealing incentives of remapping reveals the Chip for the misinformation it provides!! The the boosting of the fuel rail pressures by Plug & Play Chips alter the fuel injection quantities being injected into the engine, the ECU is requesting a certain amount of fuel to be injected that then gets altered and increased by the chip, the ECU is unaware of this external input and extra fuelling being added to the vehicle which completely skews the on board trip computer to show large savings via the cluster of vehicle but never relates to actual real world savings on fuel!! This is why ECU remapping reigns supreme because the ECU is always involved in all processes knowing fuel quantities constantly and providing accurate and safe feedback and power levels!
