Installed AEM x-series gauges for wideband AFR, oil temp and oil pressure, and wired the analogue output from them up into the doctronic ECU so I can set a "limp mode" in case something goes wrong!
Oil temp mounted into a sandwich plate between the block and the oil filter and oil pressure mounted to the factory oil pressure location with a K-tuned adapter so both sensors can be run
They are housed in a very nice 3d printed gauge pod holder that mounts in place of the centre air vent (from a very nice Bulgarian chap on a honda group on facebook who managed to print me a right hand drive version for a very reasonable price).
