Default Coolant Temp win WinAldl

Iam now wonder if the coolant temp may be causing my code 33 on startup and not when hot. Do these figures look normal.

On start up first thing in the morning WinAldl is showing 161.2 and when it gets warm and no code 33 its showing 128.1

Shouldn't the values be lower when its cold ?

Iam going to check it in the morning when its cold. I just wasn't sure if winaldl figures in raw data were the coolant temp or voltage.
Thanks...

Well i checked the CTS and it was fine but changed it anyway as it was old and cheap. Did not solve the code 33 so i guess the figures from winaldl raw data were correct.
Thinking after the first of next year ripping all the tbi out and installing a carb setup and msd distro.

Yes, there is no way your engine is going to "cool off" after starting it.
Something is not being read correctly.

It does, as all 1227165 ECMs do.

The ECM starts up in 160 baud mode and the software and hardware need to send the "secret code" to get it into 8192 mode. Works just fine in 8192 mode on my Diacom setup.

Just tried to get it to work but would not sync. Looked at my connector and it is missing all but pin H on the bottom row. No pin M (8192), has all pins on the top row but Pin D. so I tried Pin E but it would not work at 8192.. Is there another pin to get the data off of ?

Does your ALDL cable have a 10 ohm resistor?
Just noticed Moates.net is gone.
So maybe someone has an alternative site to order usb cables from?

Moates site is up? Their cables operate both, because they have a switch. Does it have an open close switch?

Yep, A 10K between Pins A and B. I can toggle it in and out. does this trigger the ecm into sending 8192 if out, I have it in for 160 ..

'86 only uses pins A, B, C, E, F and G. The data comes out of pin E.

You need to connect the 10K resistor to pin B and the software also has to send the correct handshake sequence to get the ECM into 8192 mode.

I have it between Pin B and A(GND).. I built the one on winaldl website. Is there a different schematic for the 8192 ?
