Toyota Tacoma ECU remapping
7 files available
About remapping
The Toyota Tacoma accounts for 7 files in our catalogue, split between the 3.5 V6 and 4.0 V6 naturally aspirated petrol units. It is a mid-size pickup built for the North American market, with a strong reputation for durability.
Stage 1 makes up 6 files, with 3 speed limiter removals and one EGR off. The ECUs are Denso references including a 76XX unit. Being naturally aspirated, the gains here are modest by nature.

How much does a naturally aspirated V6 gain?
Considerably less than a turbocharged engine — there is no boost to adjust. We are honest about this: expect refinement in delivery, not a large power figure.
Does it affect the four-wheel-drive system?
No. The work is done on the engine ECU and does not alter the transfer case or the low-range gearing.
Is the work reversible?
Yes. We always keep the original ECU file, so the vehicle can be returned to its factory configuration.
