Yeah wideband is not necessary but CLL certainly improves economy a touch.

As said the tune should get you decent economy on its own but if it was only tuned on a dyno then they may not have bothered doing cruise AFR'S.

I was going to say in my first post that the power seemed low for a GTR....... If it were me I'd go somewhere else

I have a Power FC Z32 AFMs and my O2 sensors turned off since like 2009 maybe and I got around 650km from a tank full ( just shy of 60L ) earlier this year

Fix what you know isn't right first before looking for something that might not be right, if it still has the compliance cat then piss it off and get a good metal cat in there, no more then 200cells per inch, no less then 100 then go from there

I'm talking about my 32 here if it wasn't obvious :D

Don't wish to be rude but I have heard people before saying they can't find any decent RB tuners in Brisbane - if you can't make it all the way to Sydney it seems Guilt Toy (Anthony) is back in Australia and has a dyno in Newcastle. Might be worth the trip (and yes got rid of the O2 sensor when I got my Link).

BTW if you don't change your cat and do go back to the same tuner ask him to drop the exhaust and do another run.

Mercury Motorsport, home of NITTO and NITTO II, the later which set a new world record for a GTR on radials. Quickest and fastest 7.93 @ 175Mph.

Might know a thing or two about tuning an RB. In Brisbane too.

Suprused you would buy a link and run a shit cat.

yeah i know, its been on the to do list for a while but when i bought the link it was extremely cheap, but ive booked it in to have the cat replace next week then its going back for a retune

i was orginially planning on going to mercury but ive heard some bad rumours about them from some other gtr owners ive spoken to.

definately go back, i have had no problems with my tune from them.

replace cat and check for any leaks.

or grab a wideband and touch up the tune yourself

yeah im sure its something small and theyll figure it out when it goes back in for a retune.

      Agree with Rob. I recently did mine and replacing with a brand new unit made the most sense compared with rebuilding my existing gearbox.

      Rb25 trigger kit and timing misalignment

      By GTSBoy · Posted

      Are you suggesting that the kit did a cheap and nasty job of just jamming the wheel in between other things and caused the misalignment? I mean, we normally do this with an integrated crank trigger wheel, not something bodged on. It's not 1995 any more.

      R-chassis INNER tie rod torque spec?

      By joshuaho96 · Posted

      I mean, given the number of BMWs you own their tolerance for improper torque is rather low. The number of torque + angle spec bolts and non-reusable bolts in one is nuts.

      Question about BoV on RB25DET NEO

      Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.

      Rb25 trigger kit and timing misalignment

      By drifter17a · Posted

      Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.
