'90 MX-6 Speed limiter?

My friend has a '90 MX-6 with a 4 cylinder. anyways it shuts down at about 115mph. how can we raise this or remove it? is it computer controled or?

Your friend is either going to have to buy a new ECU that is remapped and has a higher/no speed limiter, or a stand-alone engine management system, like a T.E.C. series or a Haltec unit that allows independent tuning of the engine.

wow not for his beat up car, are there any cars that use the same ecu program but different speed limiter? we tried one frome a probe of the same year...

None that I know of off hand, but there's a chance that the ECU in your friend's MX might be able to be remapped itself. It's doubtful, since the chip in my 323 isn't remappable, but hey, it's an option you might want to look into.

Hey i have a 1990 mx-6 the actual limitor is own the speedo, take it apart and clip the metal wire on the inside and your done i did it then up graded my fuel pump i top out 130 now not super fast but for a humk of junk its better

i dunno about that exact model, but on my ZE all I had to do was cut a wire @ the ECU. Look into how the speedo is wired and see if you can do the same

Hey all that i had to do was remove my tach/speedo and cut a metal ribbon that was on my speedo, now i get up to close to 125mph but i dont have a turbo
