Sent ECU to reputable company to be flashed...sent back to my mechanic to install and car will not fire....took ECU out again and sent to be re-flashed or corrected...put back in car...still will not fire...my mechanic is "baffled"...any ideas?????...He has checked all the relays etc and car ran fine before the ECU was remapped....Thanx....Steve C 97 993TT

 

Hi, Sorry you're having problems. You need to borrow an ecu / get a spare one to check / see if your car will start with a different ecu. BTW if you can't find a 993tt ecu, a NA ecu will start a turbo/our cars, it just won't be able to control the boost but for trouble shooting a NA ecu will apparently work. Good luck.
