M35 Wiring Diagrams And Radar Cruise

[andynogo]

Have a few questions....

Has anyone translated the m35 wiring diagarams yet?

My ARX has the radar cruise which is great apart from the upper speed limit. Due to ?wrong? sized tyres etc, real top speed is 104 km/h at an indicated 110. Obviously this is insufficient as I wish to cruise slightly higher than that out on the country WA roads!

Yes, I know I can get aftermarket cruise fitted (not sure about flying Chris Rogers all the way over here tho!), but I want to try fiddling with the factory cruise first.

I haven't heard of anyone cracking the ecu yet and reflashing it...so, can I confirm if the cruise is a standalone unit or fully integrated into the ecu?

Is there an ecu piggyback/replacement that can alter things like cruise speed?

Possibly a simple solution is to fit a speedo corrector from Jaycar (KC5435) and use that to alter the speedo signal going into the car to show a lower speed than you are doing (so allowing a higher real cruise speed). Would this affect the running of the car much? It's probably something I'd wire up with a switch so it would only be used with cruise on the longer runs.

Thoughts/advice?

I dont think that Jay car unit will work on this car either (unless its a newer one that my friend had).. i think its for more older cars. a friend made one up for his BA ford and it wouldnt work dew to newer technology in the ford... which no doubt has been in the nissans for alot longer..

Any idea why not? The unit I was think of intercepts the electronic signal (pulses) at the gearbox and alters the pulse frequency up or down to change the speed reading interpreted by the car's computer.

Not really sure how that can not work.....

Yer he said it wouldnt work with his ford caus it was newish.. i think its for more older type cars.. you'd have to ask jaycar about it.

...or pump them up so they 'grow'... 150psi should do it....

there is another wiring diagram booklet on IM if anyones interested. if not, youll have to wait.............
