Hey all,

Car still pretty new so not much chance to really push it, but I have a question, is the ECU locked in regards to maximum speed, i.e. 180kmh as most japanese cars?

If so, what's the best way to go round that? hack the ECU or put in a new one (and hopefully get a little more performance out of it too)?

 

yes, speed is electronically limited to 187km/h.

u can install SLDs(speed limit defencer) to remove it or u can change a new ECU to do that and at the same time gain abt 10-20(max) hp.

Well i know of HKS ones but not sure about Motec, microtec, e-manage and some others that u can read abt in the forums....

 

^^ yeah there's HKS SLD to remove these speed cut,but so far as i concern its work on manual only anyway what do you mean by new ECU?

 

er, i meant aftermarket ECUs that take over full control of fuel, ignition timings, bla bla bla...

A full replacement on engine management but still rides on stock ECU for domestic controls like windows, aircon bla bla bla...

 

i get what you mean a re programme ECU
