Hi, I bought uprev recently and did a few datalogging, but it is useless to tuner as the afr ratio wasnt recorded. I have looked into cipher parameters and i only manage to get AF WB-1 and AF WB-2 which is measured in voltage not the actual ratio. Any idea how to add AFR parameter into cipher?
Thanks

Yup, read the instructions. ;)

Failing that. Memory is a little hazy, haven't used it for a while.

Go into the options menu at the top, down the bottom should be an afr/wideband section.

Enter that, and type in your ecu part #, and type of wideband.

Logging will then be in AFR.

Question is.

What tuner doesn't have their own mixture sensor attached anyway.....?

A remote tuner I would guess.

Not sure I would be trusting an old oem wideband sensor though...

Good point regarding remote tuner.

In my experience they have been dead on accurate. And have the ability to read further up the line than the one your tuner sticks in the end of the exhaust.

Also, it can point towards single bank issues if one is leaner than the other. It's a useful tool. ;)

      R32 gtr transmission strength, billet plate

      I thought it could be an issue because the standard plate was flexing when stressed. Maybe the original gear set will hold a bit better without flex? Last time on the dyno it made around 670nm at the hubs. Now it have bigger turbo and better intake but have not been on a dyno yet. The car is being used from family trips to drag race events. So the shifts can be a little violent. It is grinding if I shift to fast so was thinking I should overhaul it soon.

      GTX2867R GEN 2 NO OUTPUT FOR BOOST SOLENOID

      From the factory on RB26s there's a fitting on the intake manifold collector/"plenum" that provides pre-throttle boost signal. That's how they did it back in the day, I figure it's fine to replicate it.

      Nissan Skyline R34(ER34) Front Suspension Noise

      I would be surprised if that wasn't the issue. It's probably telling you, that even if you remove the plastic liner, you may have some other clearance issues that may occur too in some scenarios. IE, tyre to guard. It looks like someone has already rolled the lip, but you may still have issues in the future IE, turning and hitting a bump etc. The fact it changes how bad it makes the noise when you are going backward vs forward is highly indicative that it's the tyre rubbing. They do make a terrible sound, even if you're only pushing a project car that has a liner hanging down on a tyre!   Has the car been lowered? If it has been, what is the measurement from the centre of the wheel hub to the lip of the guard straight up?

      Mark's a bit smarter than people give him credit... He'd convince the person that is to become dead, to drive him to the forest first. That way his car has no evidence in it, and he's free to dispose of their vehicle permanently how he sees fit too...
