2.0.1 P&H kit ordered from Jean! Hopefully then I'll be able to just turn the key and drive away, rather than priming the shit out of it to get it started.

Fuel pump output changed back to LSD style and functioning normally. The fault wasn't wiring, it was circuit design. I failed. Details here: viewtopic.php?f=9&t=2281&p=38294#p38294

It can stay this way until I get time enough and desire enough to crack open the Jaguar and add the parts to make it work.

One down, many to go.

Coolant sensor measured and thus calibration obtained as the default was wrong for it.

Stall out after rev up cured with some extra timing below idle and above cranking and below in vacuum at idle, too.

15kPa row for lambda and VE zeroed/leaned out for overrun efficiency. Unsure if I get into those zones or not, but it seems like I might.

New tuning laptop (old machine given to me by a friend) all setup with Debian on it, hostname: tooner :-D

EMStudio, OLV, firmware tools, source of various things, lots of deb tools, the Ultimate* series of tools, etc. All rockin' and ready to roll in FreeEMS style! :-D

More news as it comes to hand!

Car was running a bit rough yesterday and this morning, so I cracked out the new tooner laptop at lunch time, and noticed that the air temperature was -67.7C. Brrrr, chilly. I then found my shoddy solder joint wasn't a joint anymore and configured the firmware to 20C fixed in EMStudio, which made it run nicely again for the drive home. Tonight when I got home I fixed the joint and deconfigured that option again. Still runs fine, so I guess all is well. :-D This was a story about someone who did a bad job alone in the dark. It was also a story about how the car still ran reasonably most of the time at RICHER than 10:1 AFR (off the scale, no idea how rich it was).

MAP vacuum line replaced and rerouted. Was full of fuel :-o Joys of TBI, I guess. Should be better now with the new routing.

TPS hooked up! TPS signal is backward, 90% at idle and 0% at WOT. Code to support this will be added fairly soon.

The other IAT wire came off recently, leaving me with trouble under heavier loads. But after fixing it tonight it still ran rough indicating that the high voltage required to jump the gap might have damaged the coil internally. Woops.

And now it drives fine. Self healed overnight? May replace it tonight anyway.

Need some proper vacuum line! Current stuff is collapsing :-(

Kit arrived from JBPerf, and it's tiny, and looks nicely done! Love it so far! :-) Will build tomorrow evening and try to install too.

Also want to make the throttle stop more consistent and add a cold idle valve of some sort.

Then its tuning time and once tuned, its staged injection time. And once staged, you guessed it, ITB time :-D And then outboard staged injection time :-) mu ha ha ha...
