Hi all. Long story short i was looking for my radio fuse on the 300 the other day and i took the wooden panel off the floor of the poassenger side to reveal the ecu. i noticed that there is a big project M sticker on my ecu. Does this mean my 300zx has a modified ecu or that it has been chipped? or does it mean that i need it remapping to get extra power? Has anyone heard of this? il try and get a photo of the sticker. cheers, Steve

Just take the cover off the ECU and if the chip fits in a socket it has probley been rechipped.

Not one I've heard of, but like Vinz says, take a look in the box.

if it looks like this its standard that is if you have a manual TT like me ;)

 

Easily remedied ! ;)

yeh its a manual tt. so if its chipped and i open it up i should see the chip inside? im clueless sorry lol.

If you see something different from the picture above, then yes, it has been modified.
