November 22nd
Repacking of bags, slight tuning of engine, clean up of workshop, checkout of hotel, 4 hour train ride, search of several people crossing the border (fuck border patrol bastards, way too paranoid about genuine people!!!), and an AMAZING ride in the mighty snot rocket from the train station to Sim's house where we just finished talking at nearly 4am. Pikers include Mike, Jeff, Andy, Isabel. Peter, Sim and I held on to the bitter, cold and very tired end :-) Another great day!
Some video of this eventually, hopefully.

Got back from Canuckia and checked into the hotel before heading down to the workshop to turn on the heat and then prepare some code. Ended up not going back and instead coded until I had a working result. Most of that was with Peter looking over my shoulder kinda pair programming style. Snoring ensued.

Today may have been brief, but was a great success. HUGE thanks to Peter for making it possible at all. What a legend. I nearly cried at the airport after he dropped us off. Will miss ya! <3
Fired up the car on DBW and it ran fine, so shut it down and added an idle feature. Fired up OK, but forgot to setup the axis, so shut it down again and did that, then fired it up, and step by step tuned the throttle opening as it warmed up. But...
Then it started to idle low and die, right after I gave it a solid rev. Hmmmmmm. Then we noticed the fuel filter was empty/dry. Uh oh. Just at that moment Mario arrived to say hello, bad timing. Had to bleed the returnless rail out to get it to run at all. It would fire up and then die. Got it bled out and it ran nicely again. Success.
I think the calibration for the dual TPS was different on the car, compared to the spare, so closing the opening down to zero didn't make it idle lower. Either that or a leak, I guess.
All in all, success. The car now starts, idles, warms up with a reducing RPM over time, and revs to the limiter from the throttle pedal. As a bonus, when you turn off the key, it dies, as it should, but didn't. The only thing missing was A the auto gearbox control needed to drive/abuse it and B the fancy stuff like vtec, vtc, egr, variable intake geometry, etc is not used, yet.
Videos soon! :-)

Re: Project FreeEMS Powered WikiSpeed! (No 3g/56k)
Now that the WikiSpeed part of the trip is pretty much done and dusted, there will be no more daily updates. However I will be uploading some videos, and the first one is available now:
Hardware and code verification testing: http://youtu.be/8355cYz_RVA
Be sure to read the description! Ditto for later vids, too.

Key off = engine off, credit to Peter for engineering the wiring setup for this. I did the code and PCB hookup/pullup. http://youtu.be/EZ4R--vZYDs

Edit: These documents are already out of date. We used A17, A25, and A35 to hook up the accelerator pedal position sensor.
Edit2: Some more part numbers not listed in the pictures. These could be wrong!
A: 1717138-6
1827108-1
B: 1717138-5
1827109-1
C: 1717138-4
1674419-2
Cavity Plug: 1612108-4
Wire Cover: 1746089-1
132 Pin Cap: 1717139-1
1903287-1
These are also Tyco Part numbers. The numbers without descriptions are "related parts", and I didn't bother to research them. You'll also need some of those wire to pin contacts like a 1612776-1 or similar.

FreeEMS DBW with open loop idle control working nicely for the first time, less than 15 minutes after being written (in 5 minutes): http://youtu.be/Eiuk_kSNfEk
And A24 and A34, too. But the secondary APP signal was not connected, nor used (obviously).Peter wrote:Edit: These documents are already out of date. We used A17, A25, and A35 to hook up the accelerator pedal position sensor.
