I have 96 Camaro , I swapped engine to L77 engine I took that engine from 2011 caprice SS.
my issue the gauges not working properly. RPM , Speedo, oil pressure. Should I replace aftermarket gauges ( Dakota or NVU ) or can I keep the original gauges ?

 

Lol okay. What else was swapped over?? ECU? Your gauges probably aren't compatible with the newer sensors from that engine. You'll need either get sensors on the engine that will work with your gauges or just go aftermarket.

 

You might need to do a segment swap.

 

Yea, need to know the PCM here...

 

The L77 engine ECU is E38 . I replaced the LT1 oil pressure and temperature sensors It works, but not as required and also RPM . Speedometer not working.

 

For new engine E38 ECU
