I'm at nearly 400ks for this current tank and it's getting damn close to fuel light time. I reckon I'll just nick 400 when it comes on. I would expect better for the driving I do (works out to be around 15l/100ks).

Mostly suburb driving. Still haven't figured out what my crappy miss is. Starting to lean towards coil packs. Might try gapping my plugs down and see if that helps a bit.

there is a procedure to get the stock ecu to flash it out

or buy a new one

check your pcv grommet, mine was cactus and made it idle a little off

I get 4-450 every tank depending on how much of a thrashing it's been getting.

I've got a PFC.

Haven't checked the PCV yet.

Back from out little Cobram camping trip yesterday...

Filled up with 74.52L. Trip said I had covered 964kms.

12.9km/L or roughly 7.8L/100 :)

Downside was that there is a section of my current map that dumps fuel like no other (can see the economy drop 5-6km/L on the leaf almost instantly) and causes a "Bank 1 too rich" (0172) CEL. Just pull over and clear it. Doesn't pop up again unless I forget where it is (throttle pedal position at certain speeds).

Didn't show up at all yesterday :D

That's bloody good economy Cam!:thumbsup:

Has yours been on a dyno yet, or are you just running a "Guesstimate" tune atm?

Be very careful Cam... your economy is better than my car and I know I am running lean.

Yes. It was an a dyno for a tune, but had a clogged fuel filter (prob the one from factory as I'd never changed mine).

Massively lean above 4500rpm but below that the AFR's were "good", so it was only tuned below 4500rpm

Filter changed last week and my normal economy of 9.7km/L dropped to 9.3km/L (same driving) and was much more difficult to keep high.

Seems very lean Cam, want to borrow my spare wideband?

Yes, will need to work out a time to come over methinks.

Be very careful Cam... your economy is better than my car and I know I am running lean.

So I hear :)

170k's to half tank. BP98 :(

Half a tank might not be half a tank. Run it to the fuel light and then see how much it takes to fill and calculate from there.

I'm just managing to squeeze 200 ks out of 30 lts of premium just city driving , this seems like it could b better , only had the car for a short while ( 250 t rs four ) aero pack , really enjoying the ride but would like some better economy , can you make any adjustments on the trip comp to the leaness or do you advise a run on the dyno , it's due for a service in a couple of months what should they be doing to improve economy

You cant tune without some method of adjusting the timing and injector pulses, like an emanage or Fcon. Even then you will find on cruise there is little improvement in economy as the stock ecu does a very good job of it anyway. It has to, to pass the emissions test.

As far as making it all run as sweet as you can, change the o2 sensor in the exhaust, get your injectors cleaned and flow tested and run a good quality oil and all should be well. :cheers:

      Just as a thought, if it's in neutral, thats your drive line disconnect, not the clutch. Clutch slip at the dyno with pedal fully out, is actually adding a second disconnect. So it's not a clutch issue if you're in neutral. Just a bit of friction dragging the output around while in the air.

      "Cheap" bolt on turbo on RB25DET NEO

      By GTSBoy · Posted

      The HG high flow is excellent, and costs about the $$ you're talking about. But it, and probably every other highflow, uses a diffeent core than the original turo, and the original Hitatchi core is quite long. So, I think it is inevitable that there is likely no such thing as a highflow that just "bolts on" with no other effort required. And the same is likely true for HG's outright replacement "bolt on" turbos (the ATR things). And the same is likely true for anything similar from elsewhere. I have no idea if the cheap Chinese/Taiwanese complete turbos from eBay/Temu/etc are as bolt on as they claim. I mean, they claim the bolt onto the NAs as well as the turbos, and we know that can't be "bolt on". But it wouldn't matter because I'm not buying a $169 4 psi turbo for anything other than a paddock basher.

      Bummer...yeah i "need" something to "ease" up the work and for my driving it would be enough.    Iam counting the tune "without" turbo. I do not mean "cheap" like something from Temu around 200 USD, "Cheap" is something around 1000 USD?

      Starter motors used to use the weight of metal (magnets) to provide torque. Now they use (more) current instead. This. It's completely normal.

      So thing that had me stumped, but I think is OK....is that when it was up in the air, in neutral I had it running to bleed to coolant while I put the wheels back on. I noticed the rears were turning (slowly) which I'd never seen before 20250928_163512.mp4     Because there had been an issue with clutch slip due to pedal adjustment on the dyno, I assumed there was still and issue so spent some quality time upside down under the dash adjusting the pedal....but no matter what I did the wheels still turned in neutral. Even disconnected the master cylinder to pedal rod and same. In despair, I even removed the clutch slave so there was no chance of any preload causing it.....still happened. So either: 1. Something is not right in the bellhousing, or 2. Its a thing sometimes with cold, thick gearbox oil Internet says it might be 2, I hope so!
