engine full cut

Post by martysauce » Fri Jun 03, 2016 4:45 pm

hi guys not really about a z but some help would be great. my friend has an s13 with has an rb25 in it. we took it to the track and it seemd to have a speed cut at 200 (which is weird because it has a z32 ecu and im pretty sure my 300s speed cut used to be 180.) he sent the ecu to rapid to have the cut removed and just found out today it had already been done, so what could make your car do a full cut at the same speed each time but not be the speed cut :?

Could the signal to cut be coming from the speedo?
It's always a good day when you drive a Z
