The Problem: On the Vauxhall VXR models alot of them have common issues with pistons melting. To solve/help with this issue you must upgrade the injectors. But you cannot simply plug and play with these injectors they need programming in via datalogging and ECU Remapping
The Question: The customer has bought the 395cc injectors and now I need to know what data you need to map them in and is there an extra cost on the file?
The Answer: For any aftermarket injectors we require full datalogging from the car to see how the car is coping / running with the injectors fitted. To map these in it takes alot longer than a standard tune. Therefore to perform this level of mapping it will use up 2 file credits. Please see below the required data for mapping in stage 2 / uprated injectors.
You will need to provide the following datalogging as a minimum:
intake air temp
long term fuel trims
short term fuel trims
Injector quantity in mg per stoke / per cylinder
Failure to provide full, correct and accurate data could cause engine / piston failure.
