The Challenge

We will in this post dig into how tuning the Isuzu ELF can improve both your business and the driving experience. We know that having a business is not always smooth running but with a custom tune from Alt Tune your truck will be.

The Isuzu ELF has been popular since its first generation in 1959 and hit 1 million units in 1978. Its rugged and durable body makes it a good choice for a wide range of trucking needs. It is powered by its 3.0L diesel turbo 4JJ1 engine. But the factory power is not always enough. For people who want to upgrade their ELF, for business optimization or the full driving satisfaction ECU tuning can be the answer.

The Solution

ECU tuning is adjusting the vehicle’s brain to perform in a way that will accommodate your needs. Need more power? or more towing capacity? We can give you that. With a custom power tune your ELF will become more powerful and more responsive. This will save you time and money and as a bonus the ride will become smoother, therefore improving the driving experience.

Being a diesel truck means that the emissions system can cause problems. These problems can be solved by adjusting the emission system to the tune. It is all done by adjusting different parameters in the ECU.
