Ok, so I sent my SR and ecu to my friend's shop for storage. Problem is, he mixed up the ecu's and is not sure which one belongs to me. He has a red stamped ecu and blue stamped ecu. Which one should go to a red top S13 with manual transmission?

 

My stock redtop ecu was red stamped

 

Ok, I was freaking out for a minute. I'll make sure my boy has the right ecu lol THANKS!

 

I think it says 62 on it as well...

 

I'll text him the info, thanks bro!
