When you've not got a big fat porker every little bit matters.  :thebird:

Damn right!
Well, put it this way, I get wheel spin rather easily now whereas before I had to force it, which my clutch would not thank me for

[tomaky]

That might be the most asbo thing I've read from you [emoji23] the r888s refuse to spin.

Complete turd they span plenty at Scotch Corner.
So much that you had to be rescued.

Yes I'm back obsessing about fueling and stuff, following the install of my Zero manifold and new cat.
Go on, get it out your system...
In the meantime, I've been collecting logs to try to determine where my map is failing me and causing the issues.

Created a spreadsheet that creates a nice little 16x16 table based on loading in logs from Torque Pro on rpm, throttle and LTFT1/2. Finds all the values, splits them across throttle and rpm and averages the trims.

Result so far after just 3 logs-worth are interesting already.

You know what that's telling you don't you?

never mind that, a man of your talents with all those divide by zero errors!

Don't even..

I was going to add error handling  into the formula but its already quite long!

Once I start adding more parameters (timing and o2 voltage) I'll switch to VBA to do the analysis

I reckon if I do the same for o2 voltage and cross-reference against trims, I can get a decent impression of the stock target AFR map
0.45=stoich., so it should be easy to map out where it's targeting 14.7...which I think is damn near everywhere but full throttle

=IFERROR(<your existing formula>,"")

Will fix this. Sets all errors to blank cells.

Did this on my version already.
But, with a few thousands rows of data so far, it has made it very slow. So, going down VBA route now.

[shnazzle]

There we go. Can now flexibly choose the table resolution as well.
I tried doing a 64x64 table which leads to even more interesting results.

The only thing I don't like is that I'm averaging the LTFT bank 1 and bank 2. The core assumption in that is that both sensors are equally accurate, and that fueling across both banks is similar. It hides that one bank could be running leaner than another for one reason or another.

What this tells me is that my low load areas are smashing but the part throttle areas not so much.
Good news is that it seems to be an almost flat value of about 7%. Easy fix!

Oil and filter change today.
This little doodad on the oil bottle is awfully handy


Whilst under the automobile I did see something I didn't like, engine mount rubber is just holding on on two sides. No wonder the head steady made such a difference Time for some Sikaflex treatment. Didn't have any in the house unfortunately:


Also took some pics of the cat:

The gaps on the sides are as it's made.

But doubtless it will be floppy.

Clean as thoroughly as you cam. Tooth brush, degreaser, then fairy liquid and then water.

Jack the engine to centre the bush.  Put goop in from both sides.

Leave jacked for 24 hours to cure.

[shnazzle]

Oh that's odd. At the top there I felt a load of rubber deposit like as if the mount had been attached there at one point.
Regardless, it's getting stuffed.


As usual the engine oil replacement job was 20mins to let it drip a while and replace oil and 40 mins to remove and replace the damn nappies! I hate those things

[cptspaulding]

40 mins to remove and replace the damn nappies! I hate those things

exactly that 

[Carolyn]

in this pic, you can see an example of the extra bit of rubber-  It does not connect, it's simply a buffer.

At the age my car has reached, I consider it a grown up, so I don't force it to wear a nappy anymore...

I know! But you know me... I get worried when people start talking about how the nappies help with airflow into the engine bay and even downforce/lift!

If someone could say, with some certainty, that it has no negative effects then they'd be off.

Concerns I have are:
- the gaping hole into the flywheel (like everyone else, my little plastic cover is long gone)
- excessive corrosion, as it is an all-year daily
- downforce/lift
- engine bay temps.

@shnazzle -
I've said previously that I believe manufacturer's do things for a reason. I can't see why Toyota would put the three ( is it in total) under trays on the 2 if there were not valid reasons.
The "concerns" that you have are likely among the "reasons".

Exactly. They can't just be cosmetic.

What I do find ridiculous is the pointless oil draining "port" in the mid nappy. It's far too small so it just goes into the nappy and causes a massive mess and you can't get to the oil filter. Why would you drain oil without changing the filter.
So, on that note, Toyota designers can sometimes get it very wrong.
