VF Tuner ECU/TCU Tuning for the GX550 (4 Viewers)

[monsieurvo]

Good Morning,

This updated tune (version 1.2 of our GX550 tune)
has the following updates:

• High RPM airflow limits
• Boost targets / load limiting
• Significant update to target AFR and full boost AFR
• Ignition efficiency adjustments
• Completely redone transmission tune

NOTE, if your vehicle IS DUE for the TSB/Recall Reflash we highly recommend you have this service done FIRST.



Yes thankfully the connector itself was found (in the same place as non Aussie) only difference is wiring, which we are investigating and hope to have a resolution soon

Looking forward to the Aussie wiring being sorted, I've been waiting for over a year for this fix...

We are FINALLY back in stock. All pending orders are going out the door.
Our custom fast flash loader is also complete, releasing this weekend.

A full run down of the tune update will be posted and emailed.



I do not know if we have any reports of the issues being resolved on a fix provided by AFE, so at the present time we would still say that the intakes and our tunes are not compatible / expect issues.

Fair enough, I'll just stick with your tune then for now. Would just love to gain additional power with the tune in other ways than having to go with the expense of fully replacing the turbos.

I got a shipping notice for my tune kit back on 5/28, so glad to hear it's going out hopefully in the next day or two!

For a reference point, I have just the AFE intakes with a VF Tune and have had zero issues. I think the problems came when also installing the AFE inlet tubes.
