With the proliferation of ecu remaps now days I thought I would start a thread regarding them.
A few years ago (late 2014 I think) I had my Patrol remapped and I was initially very happy with it. As time has gone by though I keep on getting told by people that my car blows a lot of black smoke. Pretty much every club trip or when mates are following they mention it.
Having the remap makes trouble shooting very difficult as this could be injector problems or the tune. My injectors are not throwing errors or failing the leak down test but there may be something else wrong with them. Or it could be the remap that was loaded as they cannot tune on the dyno and it’s a guessing game.
It’s just hard to diagnose.
If I where to do it again I would use a unichip Q4 which is fully programable and can be tuned on the dyno. You get 5 fuel maps as well that can be changed on the fly. It can also be removed for diagnosis if there are problems. Unfortunately it wasn available when I did mine.
