Just be sure the laptop you get has an "active matrix screen" AKA TFT or you;ll be cursing it when you try to look at it while driving.

Please let me know if you're able to connect in AutoProm mode (hor. switch towards the USB, and AutoProm set as the ALDL interface type).
Also, could you email me the bin you're running that is causing you all of this greef?
Thanks!

Many thanks for all the help through this. I'd still love to know what Diacom does that will allow TunerPro to connect in 8192. I guess if I can make the APYP work as well as the AARL that's in ther now, I'll be happy.

Interesting I run a $6E now and swear I had scanned the $32 at 8192 when it was still stock. I recall using winadl first and quickly learned that it was stuck in the 160 mode and then used ECM852. It was always a pain to connect you had to keep sending the command by hitting a key. The other software packages I may of already had the $6E installed.
The late 86 vert memcal was labeled AANM. I did pull it out using ECM852 and have it saved.

Should I have used the ARAP? I assumed that was for Auto. But it is for a 3.07. The APYP is for a 6 speed with 3.54. What about my OD? Does any $6E have anything to accept the OD command from the shifter switch? I suppose the TCC will energize the OD relay if using ARAP or maybe CAGS if using APYP, but what about the shifter switch?
Thanks

Thanks

Thanks

To keep your CSI functional and use the $6E code you'll want to "zero" out the "crank fuel P/W vs ref pulse" table to prevent it from adding additional fuel during starting.

Thanks again Mark and Ken. The mechanical and electrical, I've been doing for many years and have a pretty good grasp of, it's the tuning stuff I'm a newb at.
Yes and the length of time it is activated is also based on coolant temp. The more below 95*°F the longer it stays activated. I appreciate the refresher.
This is where I really need your expertise. In comparing these tables between the two bins, first I find that the $32 bin has only 17 rows as opposed to the 24 rows of the $6E bin. I assume this means the first 17 or 24 references pulses from the distributor. No big difference there. The data field of this table appears to be a multiplier to the injector pulse width for the first 17 or 24 reference pulses. What I find confusing is the $32 bin uses a 1.00 multiplier for all 17 pulses and the $6E bin uses a 0 multiplier for the first 8 pulses, then .5 for the next two, then .25 for the next six and then .2 for the remaining eight. I can't get my head around this. The $6E has no CSI, yet for the first 24 DRPs it pulses the injectors at either 0 or a fraction. The fact that I'm too dense to understand this is irrelevant, I suppose. What I need to do is lean the $6E bin to compensate for the CSI. This much I do understand. I also understand this would all be moot, if I did as Mark suggested and disconnected the CSI. Looking into this is really just part of my tuning education. As Ken suggests, I could zero the 16 entries, but I can't see how zeroing these small fractions for 16 reference pulses would be enough to compensate for the CSI. When activated, the CSI goes open until it times out or the engine starts and this would seem to always be longer than 16 reference pulses. This is why I originally mentioned the "Crank Fuel vs Coolant Temp" table. This table shows the $6E bin to have a significatly longer PW than the $32 bin from -40°F all the way up.
I'm obviously confused so any light you can shed on this newbie tuner would be greatly appreciated.

A bit late to the party, but here goes...
1986 ($32) bins are missing a few lines in the serial data initialization routine which are intended to disable transmit through sxr (based on comments in the source). This makes scanning at 8192 baud troublesome compared to the later 87-88 ($32B) and 89 ($6E) bins.
Here's an excerpt from my corrected disassembly with the missing bytes shown in red:
ldaa L4008
ldaa #0x27
staa L4007
ldaa L4009
ldd L3FFC
orab #0x04
jsr LF3B5
std L3FFC
ldaa L4004
anda #0xF7
staa L4004
rts
With the indicated changes along with updated dependencies, my test bin will now respond to the standard mode 1 request (in 10k aldl mode) and transmit 8192 baud data.
Testing has been successful with both TunerProRT V5 and EFILive V4.
Ray Quayle, if you're still interested in this topic, I can provide you with an appropriate bin for test purposes.

Hey TB, I wouldn't call 11 and a half years late! Thanks for bringing this back. I'm about to get back into this, so please send it on.

Note: This bin has only been briefly tested with the ign on and engine off to check connectivity and data flow. It may contain some bugs. Use with caution.
Update: I ran a quick test with the engine running after adapting the bin to fit my car's injectors/maf/IAT/timing/egr/etc.... Runs fine and data looks good.
For those interested in testing, your feedback will be appreciated. Feel free to send me any relevant logs.

6,835 4+3s built in 1986...and only 2 potential testers so far...
Still interested in feedback on BUB_8192.
BUB is an iron head bin as far as I'm aware, so timing may be conservative for aluminum heads.
For aluminum head cars, which bin would you like to see adapted? AMJ, AARK, AARL, AMA, AML or BUM maybe? Not sure which bcc was most popular.
Post up a copy of your base bins here.
