Sure thing :)
Techedge Wideband - $320 DIY or $500 prebuilt
Moates chip burner - $120
If you are OBD2, obd2 - obd1 conversion harness - $130
If you are OBD2, Socketed P28 ecu - $240
If you just need to chip the ecu, budget about $70-$90 to buy the parts needed. I could be way off on this, could be a lot less.
and the wideaband replaces the OEM o2 sensor?
how do you link the laptop to the ECU?
what minimum spces does hte laptop need to be?
You can do a few things in regards to the OEM o2 sensor.. Replace it with the wideband sensor, disable closed loop & heater and just run the car on the ECU values or add another bung in the exhaust so you can have both wideband & o2 sensor.
If your wideband has a 0-1v output then you can connect that to your ECU eliminating the need for a stock sensor, I am aware that you can also use 0-5v values aswel.
For datalogging you make or buy a cable, which then wires into the ecu and connects to your laptop via a serial or usb port.
If you were talking about connecting the ecu to the laptop to make changes, you use a moates chip burner, take the chip out of the ecu, put it in the chip burner (which connects to your laptop/computer via usb) and use the software to burn the new map values. If it was in regards to real time programming, you use an ostrich, but I am not very familiar with this method :)
The laptop that I use is only a P3 500mhz with 128mb of ram, nothing spectacular, im sure you could do it with a P2 300mhz and 64mb of ram :)
I use CromePro($150 us) which has real time datalogging (live tunning).

The guys that use uberdata through me use me as their tuner, it keeps costs really low that way. As I'll outline below, using a tuner who has the software and hardware will allow you to have a tuneable ecu in most cases for the cost of just a tune on other systems. The last uberdata that i tuned, the guy ended up paying an amount*, and he happily takes on silvias and 180sxs that have turbos! :thumbsup:
here are my steps that I take:
1) socket my own p28/p72 if I have one, or buy one of these readily available ecus. Buying one will cost me about 175 for the ecu, socketing my ecu will cost me about 75-100 bux depending on who I use.
2) I buy a burner if I dont have one, about 175 bux to buy one of these, and buy 1-2 eprom chips which is about 5 bux each, so 10 bux or so.
3) Hire a dyno and tune it there, I dont need to buy a wideband for this system as the dyno already has one inbuilt so just use that one! Dyno prices vary, so I wont guide on you that for pricing.
4) go out and race some big power claiming p00fs and beat them with a stocker :)
its that simple! Heck I can make it even easier, this is an even more simplified list.
1) buy/socket my own ecu 75-100 bux
2) take it to a dyno tuner who has a burner, and let him burn and tune the eprom, tuners vary, but lets say 3-500.
3) go out and go sick RE ;)
Personally, since I tune and burn my own eproms, any socketed ecu that can accept an eprom will work, a few of my guys have done a tuneable ecu solution for their car for 150 bux, plus tuning! ie all done for 350, installed and tuned. IMO its better if u know a good tuner who has the eprom etc to just buy/socket an ecu, and let him do the rest!
hope that helps
*bennjamin edit. Dont use this for free plugs :) Help a bother out , DONT push services :)
damn thats very cheap, ecu, chipped and dyno tuned.
how much do you pay for dyno time per hour?
On that note. Does anyone know of anyone in Brisbane or surrounding areas who could do this? Or would I simply have to call every place I can find with a dyno and ask. Because it's not exactly a widely advertised solution in Australia yet.Quote:

Good info here and lets keep anything not related to PM.
honestly ben, i did state at the start if its out of line to pm me and we will modify the thread together as mods see fit to keep it in strict guidelines.
I do iterate that in my posts, a wideband is not necessary to keep costs down, as the dyno u use has this already and will be given to u when u hire it out. if u choose to tune it urself, thats even better free of charge on tuning time! and if u have a burner or access to one, its also great, but ive outlined all this. Im just finding it hard to give examples
OK guys now we've gota rough idea on price so thanks for that.
Now I have a question.
What if you don't have access to a dyno but only could do a street tune. Would this suffice? What added advantage does a dyno give you over the street (assuming you had time on your side.........but not access to a dyno)?
