going to be doing base tune on a mates car tmr, he hasnt got the wideband setup yet (tech edge). going to use winlog/tewblog and want to know, to get the load signal to the wideband, can it be done via software from nistune, or do we have to actually wire it straight off the AFM?

or is there some sort of logging program that works with nistune, that can log A:F ratio in matix mode?

thanks guys,

Ben

edit - i dont think hes wired the AFM to the wideband. ecu has been internally modified for his AFM, i think he mentioned something about it working on a weird voltage scale, like 2-7 volts or some such thing. do any Z32 AFM's work on a werid scale like that (think its a z32, not sure)

The techedge will some with a serial output, plug this into your laptop

Inside Nistune use File-Configuration and then

(a) wideband set to TechEdge 2.0 wideband

(b) wideband directory C:\Program Files\NIStune\Wideband\TechEdge2.0

thats where the lookup tables for AFRs, auxillary inputs etc are

Nistune will read the load in from your ECU directly (via usb cable) and display that along with the AFRs. As crans mentioned you can do AFR tracing against load/PRM scales and record/playback with the log player

If you are using a VL Turbo ECU with Z32 AFM.... after doing the wiring to the AFM plug (make sure yellow/red calibration line goes through 370 ohm resistor to ground) then you need to modify the ECU to work with this later era AFM

The details are in the software users manual. There are wideband and AFM upgrade sections with step by step instructions to help you there. Once you do that, edit the VL turbo address file and remove the line MAF_OFFSET so the AFM voltage is reported correctly now with the Z32 AFM in the software

We have a forum for Nistune questions etc at www.nistune.com under forums also

champion. thanks for that Matt, was going to sign up on nistune forums but didnt think i'd find out in time. must say this is damn good service.

thanks bud

edit - yes, VLT, ECU has been pre modded and setup, just needs a tune to suit current setup

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.

      Nah, that is hella wrong. If I do a simple linear between 150°C (0.407v) and 50°C (2.98v) I get the formula Temperature = -38.8651*voltage + 165.8181 It is perfectly correct at 50 and 150, but it is as much as 20° out in the region of 110°C, because the actual data is significantly non-linear there. It is no more than 4° out down at the lowest temperatures, but is is seriously shit almost everywhere. I cannot believe that the instruction is to do a 2 point linear fit. I would say the method I used previously would have to be better.

      When I said "wiring diagram", I meant the car's wiring diagram. You need to understand how and when 12V appears on certain wires/terminals, when 0V is allowed to appear on certain wires/terminals (which is the difference between supply side switching, and earth side switching), for the way that the car is supposed to work without the immobiliser. Then you start looking for those voltages in the appropriate places at the appropriate times (ie, relay terminals, ECU terminals, fuel pump terminals, at different ignition switch positions, and at times such as "immediately after switching to ON" and "say, 5-10s after switching to ON". You will find that you are not getting what you need when and where you need it, and because you understand what you need and when, from working through the wiring diagram, you can then likely work out why you're not getting it. And that will lead you to the mess that has been made of the associated wires around the immobiliser. But seriously, there is no way that we will be able to find or lead you to the fault from here. You will have to do it at the car, because it will be something f**ked up, and there are a near infinite number of ways for it to be f**ked up. The wiring diagram will give you wire colours and pin numbers and so you can do continuity testing and voltage/time probing and start to work out what is right and what is wrong. I can only close my eyes and imagine a rat's nest of wiring under the dash. You can actually see and touch it.
