I don't know if UPRES uses "eeprom" of body pc for storing maps and so cars without cruise control may be have less memory or different layout and can't work...

 

bump!! any new info??? I would love to be able to have multiple maps in my car.

Anyone tried wiring up a cruise control switch/module??

 

I heard you can and it works (I think Jared mentioned it at some point)... get the steering wheel controls as well as the upper clutch switch.

 

I have the switches and would love to know how to get it to work on my ecu.

 

I wonder if we wire it if we can just mount the switch to the dash or something. I dont have a stock steering wheel.

If its possible I would love to be able to just get the switch and wiring.

 

Well the wires don't run straight to the ECU. I believe they go to a serial mux in the steering wheel (along with the horn signal) then a serial data line to the BCM. I could be wrong....but you can imagine Nissan wants to minimize the # of wires going to the wheel.

 

HMM will have to look more into this. If someone has already done it though it would be great to hear from them!!!

If it does have go through the steering wheel I would think there is a way to
1. tap into the line behind dash
2. on maftermarket setup may be able to run the wire in to steering wheel since there are spaces and such yet still be able to hide the wire.

All speculation at this point though.

 

Rather off topic, but has anyone relocated the cruise control buttons when switching steering wheels (Personal, Nardi, Sparco, Etc.)??

 

I have been looking into the prospect of getting non cruse control switching of maps to work, as i am about to buy Osiris tuner for my JDM Skyline 350GT 6MT, i have been trying to trace the cruse control wiring etc, and from what i can see in the ECU inputs, there are two dedicated to the cruse control (and this is presuming that the manual ECU has these inputs, as i haven't had time to check yet)
From what i have found via the fault finding checking voltages, resistance etc etc in the manual, i strongly suspect that the map switching can be accomplished by a sequence of voltage's generated to these pins, as that is all that the cruse control seems to do, if this is the case then the maps must also be contained within the ECU.

 

^Have fun getting that to work.... But good effort! You should talk to Uprev, or Technosquare as they will probably know if its possible or not already.

 

I have already tried that but they just do bother to answer my emails, Uprev actually offer to help with circuit diagrams etc, but they just don't bother replying to the UK
That sort of attitude makes me think maybe its not a good idea to buy the Osiris, but the trouble is what else can i use that actually available in the UK.

 

Guys, I use my map switching about as much as my cruise control --- practically never. Seriously, it's no big deal... just get a tune and enjoy the powa.

 

saw a thread some where around here that says some one crack it.
installed a cruise control all OE parts. I'm interested in doing it.
I wouldn't really car about it now since I'm on stock motor.
but will consider that after the engine build.
knowing that I will be running 93oc for weekends, and
Q16 or C16 for track use.
sub'd wana know more about it.

 

It takes a total of 30 seconds to reflash the ECU and you'll have unlimited tunes stored on the laptop... is it really worth all the extra work to be able to do it on the steering wheel once per week? Additionally you'll want to clear the learned fuel trims when switching maps like that which can also be done in Osiris but not with the steering wheel controls.

 

djamps: thanks for the info. I know that it could be done like so, but controlling the tune
though clicks is way easier. plus I'm a Mac user so I'm screwed anyway.

for higher power levels I might switch to something else like a haltech or a ProEFI.

 

I thought there was a limit to the amount of times you can actually re-flash the ROM chip in the ECU before it fails, so if your going to continually re-flash you will soon be running into problems, better to have the maps already saved within the ECU and just switch between them when needed.

I intend to keep looking into this, like i said i think its just a case of building a a controlled voltage switch pad, and then just enter the right sequence, would have been nice to get some genuine info and feedback from Uprev themselves, but i settle for any input from anyone who has also looked into this.

 

You can fire up Windows with VirtualBox and do your thing. Actually, us PC users are screwed, not you, since even with VirtualBox OSX cannot run on standard PC hardware.

 

I've reflashed mine over 300 times with no issues. Honestly that's just a myth, there is no hard data to back any hard limit with this ECU.

 

OK fair enough, just going by what i have read, also though it was mentioned on the the Uprev site, but i must be wrong.

On a side note, i notice i your sig that you have self tuned your TTZ, can you point me toward any info/tips for using the Osiris software, as its somewhat different to what I'm used to, from what i have read so far, i have been used to Power FC and Emanage Ultimate and similar piggybacks, mainly on FI, but this time i am just going to tweak the std N/A map for now, and from my data logging its rather rich, and i feel it can be smoothed out a fair bit.

 

If you have specific questions, post a new thread and there's plenty of people that can help.
