Round 2, remembered some photos this time



Also dumped one of the boxes that came with the cherry picker against the headboard, just ratchet strapped to the bulkhead for now but some much needed storage that can at least keep things out of the dry.

The eagle eyed amongst you may notice a couple of other additions not quite finished yet.

@sako243 you mentioned using Auto tune. Was this in TunerStudio?
I'm looking at doing the same and wondered how you got on with it, also why did it mess up the tickover part of the map?
Sorry for the diversion.

Yes. Basically I was advised by a friend to do the idle bits of the map manually and lock the cells so it doesn't mess them up.

I'm not 100% sure what happened but my fat fingers unlocked those cells and whilst I was at some roadworks I was struggling to keep it idling. Rather than have issues going through I quickly reverted it back to a known good tune.

I haven't had a chance to look but I did change one of the gauges to see the AFR and it was basically bottomed out. There are two AFR gauges and I may have selected the wrong one or there might be something funky happening with the wideband that caused the tune to go iffy.

As I said haven't really investigated as I was in the middle of traffic so just wanted to get home before doing anything. Just haven't had time to go back and look.

Thanks.

Confirmation today somethings not right with the wideband - had it on for the drive to my parents this afternoon (only a few miles) but the AFR gauge didn't move at all.

Well wideband investigations continue. First time I opened up the battery box the controller blinked one red led which indicated a shorted heater circuit. Then it just blinked the green initialising light then nothing indicating no power.

I pulled the wideband and it's sooty to say the least from all the oil it was burning.



Checked connections and everything looked okay, did various checks and everything seemed to be powered as it should be. I found the horrible little Molex mini fit connectors were badly loose (likely because of my probing).



I squeezed them back together under the microscope and they were much better fit. I eventually found the diagnostics connector and plugged it into the laptop. Now after the connector tweaking it's warming up to about 20% and then getting stuck there.

A bit of research and it might still be a wiring issue or the wideband might have been cooked by all the oil burning previously in the exhaust.

Next stage I think will be to pull the lambda back out and fire it up with it outside of the exhaust and see if it actually gets hot. If it does then something funky is going on if it doesn't it might still be wiring but possibly also confirms it's been damaged and a new one will be required

I cleaned mine once and it came back fine, if you clean it with brake cleaner after a scrub with a wire brush you might be lucky. I tested mine by putting a cloth over it soaked in brake cleaner once fired up and it dropped to 7.5 ( Bosch Lsu 4.2)
Second time it was dead, after trying a cheap after marker one i gave up and bought a new AGM set up and it's worked fine so far.

I've got nothing to lose really but I'll pull it out of the exhaust and fire it up externally to see how hot it gets. Then I'll give it a scrub with brake cleaner and see what happens.

The only other way to test it would be to tap into the wires for it so I can see what's going on.

 

[sako243]

Well some tidying up done so at least the nose can be pulled in. Makes getting underneath a bit easier on a smooth floor. It also doesn't fit inside with everything else in there with the bumper on but as it's my daily it's getting used most days.



Lambda pulled out and fire applied. That's a bit cleaner now, didn't get a chance to check it as I ran out of time this evening but I'll try and remember to take the laptop on the school run to see.



And a goodie arrived in the post. Typical no instructions anywhere to be found but for £98 to the door I can't expect much. Might see how much it can be dismantled in case I can rearrange it in a more suitable fashion.
