I recently just bought a Z last year used.
I was wondering if there was any way that I could check if the previous owner had the ECU reflashed?

The car is stock but seems to be a lot faster than most other stock Z's and G's out there

 

I to be honest...i have no idea.

Edit: Maybe you can call few reflash service company and ask them with ECU part number or Vin number.

 

I'm not sure why anyone would reflash a stock Z? That is probably your answer. But no I don't know how you would tell. If it is anything like an OS for any product you flash the firmware to then you should be able to look at the current version and tell? (Meaning with a PC or something) I am dabbling in something I have no idea about with our cars just speaking from updating firmwares with phones and HD receivers and such.

 

Maybe. Check the ECU for a sticker.

And the rev limiter is where?

 

Sure it is. Been waiting 5 months for a time slip.

I bet you could tell if you try going to redline . I went from reflash to osiris stock rom and i hit the rev limiter for the first time today. It seems to kick in little before redline, on the reflash there was no rev limiter.

Anyways im just kidding, dont go trying to hit your rev limiter and blow up your engine if its not there........
