Datalogging for mapping in uprated injectors

The Problem & The Answer

Datalogging for mapping in uprated injectors

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

coolant temp

rpm

boost requested

boost actual

afr

long term fuel trims

short term fuel trims

ignition advance

knock detection

injector duration

Injector quantity in mg per stoke / per cylinder

Failure to provide full, correct and accurate data could cause engine / piston failure.

Thank you
