MAP ECU-2

Since my car is JDM and comes with a MAP sensor instead of MAF, it becomes a lot easier to install a MAP ECU-2

With either setup I am going to put a Greddy electronic boost gauge where the OEM clock is and replace the OEM 180km Speedo with a TRD 320km one.

My biggest concern with going with a speed cut defender is that it tricks the ECU into thinking that you aren't going over limited speed where as the other method, the ECU knows how fast you are going and doesn't care.

Does anyone have any comments with which setup to go with.

With the US-spec, pulling the trac fuse also elminates speed cut. Unfortunately I don't have personal, first-hand experience using the HKS speed defender. There's a bit more info on this topic here:
