Youll have to learn how to remap it. However its not just a case of " upping to fuel makes it go faster. " It will go faster however if done incorrectly will result in a rather jerky map with the power in the wrong place, not to mention other potential issues to be aware of.
, also unless 100% confident in what you are doing you could end up bricking the ECU. Instagram @defender_ventures Empire Tuning - Agent |

Bricking the ECU is not the biggest problem.
I would just increase the fueling step by step and see how it drives. If the engine goes bang you have to go a step back.  Roel

in a nutshell, but there are many steps in between these
1. take the car for a drive. 2. use the nanocom to get the log of the max airflow, should happen around 2.5 to at most 3k rpm 3. calculate the ARF using the amount of airflow 4. as you move up the table you will realise that you need to extend the amount of mg of fuel needed to keep the ARF decent 5. you will need to calculate the injector PWM to find out the duration of how much time to open the injector to give you the desired mg of fuel. 6. do that for all 4 PWM tables 7. modify the "smoke limit" table to take care of the additional fuel map table you have. on the EU3 motor, there's one for light loads and there's one for "normal" use. 8. now that you have that, you will also need to make sure you take care of the boost, so you need to modify the target boost it's a nice and fun exercise where you get to change you map as and when you want and try out new things. However, if this is not your idea of fun, just pay someone to map it for you. From the land of the most expensive land rover defenders on planet earth.

Just the way I did it! Calculated airflow from MAP/IAT because MAF sensor got out of reache. Only issue is what is best AFR?
Now I run 15-16 AFR, not to low? |
