i have a 2005 jdm car namely a nissan bluebird sylphy. i have done a sr20det swap. the car came with a qg15. we have managed to start the car but want to interface the rev,speed gauges along with some other sensors to the engine. the challenge is the gauge cluster is digital leds while the sr20det is a analog interface. can someone shed some light on a possible solution. i have heard of doing a circuit to interface with the dash and wire it back to the ecu. Awaiting your recommendations
