Here is a copy of the latest bin for anyone who is interested, still has a couple of lean spots and working on fine tuning the AE but almost have the hot running sorted. Still have to make some tweaks for colder temps then enable DE, DFCO, lean cruise, closed loop and make sure all that's good.

Not too keen on driving around with the laptop open on the passenger seat so have been logging with ALDLDroid (mounted a cheap 7" tablet on the dash, it works great) but XDL logs don't seem to be any good so don't have any of those as yet.

You should be able to log with the laptop closed... look at the power management settings, and set "when I close the laptop lid..." from its default "standby" to "do nothing". Wording might be slightly different but its along those lines.

Yeah I turned all the usual settings off (its not supposed to do anything but turn the screen off when I close the lid) and it was still logging but with big gaps of data missing at regular intervals. Tried it with the lid open and works properly, seems the like the drive is spinning down after a period (it works for a while) or something like that. No doubt there's a setting buried in there somewhere but I'd prefer to get ALDLDroid sorted anyway, its a lot more convenient with the small tablet. Have it hooked up via a subversion repository so its only a button press at either end to grab the latest files.

Typical problems with laptop are the power settings and how long before they start going to sleep and shutting down screen and hard disks. Can also have problems with g-sensors in hard disks (the old spinny type, not newer SSD's) going into protection mode and parking themselves. A couple of bumps or laptop bouncing on a seat can do it fairly easily.

Time for some new rear tyres, went with Falken FK453. They seem OK so far, definitely a little better in the wet (for obvious reasons!)



Also finally got around to building a cold air box. I decided that I didn't want the air cleaner stud supporting everything, so made up some replacement nuts for the throttle body studs which incorporate mounting for the air box



Glued together this birdbath-looking thing out of sheet metal and it just screws on to the four nuts/posts



Tidy up and add a length of old Commodore boot seal (it has pinch weld built into it for easy mounting), doesn't look too out of place. Didn't really hide any of the injection stuff after all that but I didn't want it too big.



The manifold air temp drops pretty fast now when the throttle is opened so it seems to have made some difference.

Have been working away at the tune and its still slowly getting better. Every time I think about posting a log I end up changing something so the log is out of date! The hardest part seems to be getting the AE right for light throttle cruising (it would be great if 12P had some more RPM resolution between 1200 and 2000), I'm seeing similar RPM/load points under different conditions and getting different results. Pretty happy with it all round though, fuel economy will be put to the test next week.

That air intake has come up nicely Hides the EFI setup even more for that stealth look too.

The standard carb style lever on the throttle body worked OK but occasionally made it difficult to get smooth throttle application at low openings, the angle of the lever giving a fairly fast opening rate and more control in the middle of the travel. I've been meaning to make a pulley/cam type lever for linear application like a standard EFI throttle body, upon looking at a VN one I noticed its not actually linear at all - its the opposite, with progressive ratio giving more fine control at opening and faster movement near full throttle. There's around 10mm difference in lever length from start to finish. So, I chopped up an old VN piece and fitted that:


Was a little weird to drive initially but achieved exactly what I was looking for, now have more fine control at small throttle openings which makes it easier to cruise around smoothly at low rpm.

nice work

certainly makes for an un-pleasant car with it how it was, i've driven one like it before!

Great work, great thread and a nice ride.
