I'm assuming the MAF Sensor on my MY98 needs replacing as i'm getting flatspots past 4k revs in 4th and 5th when i put my foot down.

What i'm wondering is my MAF Sensor is a "purple label", does this mean i have to replace it with another purple label, or can i use a green label? What's the difference?

 

The MAF sensors are not swappable unless you have a custom ECU that can be reprogrammed forit. I also have a MY98 and also had a purple 'F' label MAF. I did in fact swap it for a Nissan Z32 MAF which is identical physically but my Power FC needed remapping to cater for this.

In normal use you must keep the original model of MAF sensor.

 

ahh nuts, guess i'm gonna have to stick with purple for now until the engine mods come in and i can afford the nissan maf and re-map all at once.

thanks for the info mate i appreciate it!
