Man1bear1big Posted March 22, 2023 Share Posted March 22, 2023 I bought a p73 ecu for my mb6 and the harness so it can go in. But is this really the best thing to use iv upgraded the cams to skunk 2 stage 1 cams exhaust manifold and inlet soon getting the s80 4.4 fd.Do i need to tune the car in order for everything to work properly or will this p73 ecu do the job.

KiNK43 Posted March 22, 2023 Share Posted March 22, 2023 I dont have first hand experience but somethings to bare in mind.. Jdm ECUs usually have knock sensor circuit so will show CEL on UK engine. It will also have a 110 mph speed limiter. I'm sure it could work but I personally think a custom map would be better. Quote Link to comment Share on other sites More sharing options...
