Yep - as soon as the air fliter pod dries out and I've re-oiled it I'll

1. Run the engine and listen for any hissing sounds from possible leaking exhaust manifold.

2. Plug in the XCAL3 and check for DTC codes (as discussed with Rab)

3. Pull the battery and leave unconnected for 10 mins (thanks mazda74)

4. Flash back in my custom edit tune.

5. When I'm on the road to Radelaide - set cruise on 100km/h and check the instanenous fuel consumption read out.

 

Not discounting issue with O2 sensor either - am guessing its a common issue though I've never encountered it before.

Just put SS Growler back together.  By the way I went around the Turbo Intercooler head and some of the cir clamps were loose - especially the one connected to the pipe from the SS Growler so I hand tightened those. That's the right thing to do - right? We're not meant to leave them loose by 1/8 turn for expansion or something are we?

 

Listened in engine bay and heard no hissing on exhaust side nor smelt any exhaust fumes.

 

When I check for DTC codes with the XCAL3 I get a P1000 error.

Is this the code that's always there if you have a custom edit? Rab mentioned something like that.

 

Anyways gonna reset ECU next by disconnecting battery for 10 mins.

 

Then plan to flash back in my custom edit.

Just to add my BF had two O2 sensors not one (thought they always had two in B series onwards?), but as mentioned the second one (post cat) is disabled in tune and now just has a bung in there.  It was rubbing against the ZF pan to housing flange due to position in aftermarket exhaust and no point leaving it in anyway!

That must mean the second one is only about cat effectiveness and not about monitoring AFRs. So if o2 sensor is the cause here, its only the pre-cat one that is in play.

Okay did everything up to putting the custom tune back in and now the average is 33.4l/100km - farrk me :roflmbo:   But only driven it around the block.  I'm just happy it starts up okay ...

 

So I'll be heading out soon to join Rab and k31th and will find out what the instantaneous shows when I'm crusing at 100km/h

Swapping the front sensor isn't a huge job - but need the heat shroud off. Maybe see if someone will swap sensors with you tomorrow morning for a back to back comparison?

Good idea, but do it at the end of the initial meet or bring your heat proof gloves hahaha
