Get it scanned for fault codes so you know what is causing the check engine light.

First guess would be that if you had a new cat installed, they didn't switch off the rear O2 sensor - but seems a bit of a simple oversight.

When you say the tuner cleared the codes, was it giving codes on the dyno that were then cleared before you took the car? Probably best to go easy on the car until you know what is causing the fault.

Keith Stewart dynopro.co.nz he is good, but not overly familiar with the zf. Tuned the barra real good. Iv been told what my zf is doing is a trans fat between gears. Do you know if the trans can start doing it as protection when it senses too much power? @JETURBO

Oh right, you’re from N.Z, zero good falcon tuners there lol 

If your tuner doesn’t know about the ZF transmission you’re definitely in the wrong tune shop 🤨

 

Anywhooooooo the ZF “trans fart” actually isn’t from the transmission itself it’s from commanded spark cut in the torque reduction which again isn’t within the TCM but the ECU 

 

what you’re experiencing is a factory characteristic, not a tuned characteristic.... it’s just when you increase power the “Fart” gets bigger and louder and longer duration 

 

this is very basic stuff that any falcon tuner should be able to explain to you and know how to manipulate ;)

You can't just clear the sensor code, you need to disable the rear sensor so it doesn't recur after a few hundred KMs.

Part of the rear sensors job is to check if the cat is working correctly, which it doesn't when you don't have one
