Used the limited VE learn info from today's trip to work to build a new bin. Unfortunately winbin didn't like the ecu file, so I didn't get to even out the maps. Went with the learn only. Also increased the idle speed to a min of 600 rpm, since that's about as low as I expect it'll run smoothly anyway.
sub003.bin Promid=3 Doubled the image to use in a 27256 eprom.

Road trip
Used my potentiometer/IAT and set the temp to 40dC. Let's pretend it's a bit warm.
Hit the key and she comes to life. The stinky flooded hydrocarbon smell is gone and she's running pretty well. Idle is at about 600rpm. A bit rumpy at that speed, but running OK for a first start.
Drive to work with datalogging on. Notice a misfire at 2000rpm and mid-throttle I'll have to tune out. Otherwise, she's running better all the time.
Will use this trip to create a new "learned" bin, then start on the TCC/shiftlight/kickdown logic.

Aha! ECU file revelation
Address 7DB is in there twice, with an extra blank line to boot. That messes up the syntax.
With that corrected, my awk script works pretty well at pulling out the proper variables and numbering the Items so that the file looks nice.
Used my custom ecu file to edit the bin.
331ci,55#/hr injectors
Burned the chip. Will test drive tomorrow.

Night 5,6,7
Spring Break. Worked at a site close to the beach one day and added a little beach vacation the next day. As nice as the Gulf Coast Beach (Gulf Shores, AL) is, I wish I were tuning.
Night 4
The IAT pin doesn't even have a wire in my connector. I put some solder on a stripped back wire and stuck it in the hole. Connected to a potentiometer and grounded the other side. Instant settable IAT. :)
Truck runs now without SES light.
Test drive shows proves that she'll run. The VE cell in use is highlighted as the engine runs. Very nice. The software will create a new bin with edited VE tables as learned. Very nice.
Start stripping settings out of the ecu file. There are bunches (322 as shipped) and promedit will only read 245 or so. Created a little "awk" program to strip addresses for a new ecu file. It's still having problems though.
Post to TGO message board so BobR will know I fixed the SES and his work is paying off...and so others can have some encouragement.

Night 3
Heck with editing the bin. Tried burning the shipped one. Truck cranked but SES light was on. The USB-to-serial cable I bought uses COM5. Once that connected and I found that the EBL's WUD interface shows error codes, I saw that IAT was low. Duh, it was not ever installed.
EBL Self Install
Second night:
Got the non-chlorinated brake cleaner and cleaned the goo as described. Used pencil torch and "played" the flame across the connectors to remove the daughtercard. Cleaned up a couple of pins which had excess solder using a small soldering iron. Installed EBL. Used dremel to cut out the case for access to the new connectors. The calpack has a line marking pin 1, and the eprom has a divit in the top. The EBL board has a divit marking pin 1 on each as well.
Tried loading the included bin file in promedit with the included ecu file. Bzzzt. No joy.
