Once we have determined and agreed on the modifications you have installed on your vehicle we will supply you with a base map to start the logging and tuning process.  Once we have determined and agreed with the modifications you have performed we can then send you a base map to begin tuning. When you have installed the map into the vehicle ECU we will need to go through the logging process. When a log has been completed please send us the log, we will review it and send a revised map for you to log again. This process can take a couple of revisions to get the map dialled in to your modifications.

Logging & Driving HOWTO

1 First log we will need:

Firstly ALWAYS make sure the car reaches operating temperature before logging unless logging cold start.

Once the car is fully warmed up cruise around at steady state for about 10-15 minutes. Steady state can be though of as NO rapid accelerator movement and only slow and controlled throttle requests.

Log partial throttle, and about 5 psi of boost.

2 From here on email us the logs to the specified email address. The second log we will need (usually after sending a revised map) under similar conditions to the base map.

3 Stop there and send logs, if things are good we will require a third log (usually after the previous maps and logs are satisfactory)

4 Log, partial throttle, into about 10 psi boost send us the logs

5 Log, full throttle pulls from 2k-Redline send us the logs


Your car MUST be in good health / and mechanical condition with NO issues. We cannot tune your vehicle and will decline the tuning request, we can not tune round hardware issues.

ECUTEK requires a licence to be added to each ECU. NISSAN GT-R needs ECM & TCM to run all features correctly. Please revert in a timely fashion as per our terms and conditions It is recommended getting back to us with logs within a timely fashion as we get 100's of emails and logs every day. Also please ensure you reply to the email we sent you with the relevant logs, it makes keeping track of logs much easier that way. We ask that you do not seek technical advise from DIY owners, forums, facebook groups or similar. Please ask us first we are the only people who actually knows what is going on in your tune.
