Tune the maps that matter: power, torque, economy, throttle response and emissions-system behaviour.
ECU remapping adjusts the control maps inside the vehicle computer so the engine is calibrated for better efficiency or savings. Optima handles light, medium and heavy diesel applications, from utes and vans through to machinery, smaller trucks and heavy-duty fleet vehicles.
Send Jack the vehicle details and current symptoms, and he will tell you what is realistic before anything is booked.
We decide whether the job is about power, fuel economy, torque delivery, emissions-system support or a balanced combination.
The original file is read, adjusted and written back with the right equipment and file set for that make and model.
The machine is checked after remapping, with dyno verification used where the job requires measured before-and-after numbers.
Coverage is engine-led, so the exact make and emissions package matter more than the badge on the bonnet.
Every machine has its own history. Warning lights, fault codes, duty cycle and previous repairs all change the best answer.
Every engine is different, but the old Optima material uses indicative gains of up to 20% on diesel power and up to 30% torque where the engine package allows.
Yes, if the map is built for economy and the vehicle is driven in the right duty cycle. Not every tune is a maximum-power tune. This is very much operator dependent
Many remapping jobs can be done on site. Send the vehicle details first so Jack can confirm the right equipment and file availability.
No guesswork, no generic internet tune file. Tell us what the vehicle is doing, what has already been replaced, and how urgently it needs to be back earning. Jack will come back with the most sensible route for this ECU job.
