Having alot of trouble with getting obd1 data using WinALDL. Com port is configured correctly, winaldl reads data down to the tps sensor but nothing below. No BLM tables or anything else. Any suggestions?
ECM module is 1227747 and WinALDL reads fine.. raw data but but nothing else. No dash readings in Winaldl, no o2 nothing. DataLog available.

 

Make sure that you set Com port bit rate to 4800 in WinALDL....

i hate to bring this old thread back up but im having the same problem with it set at 4800 with com port 3 ok'd. its a 165 ecm and when i first turn the key with the resistor on i get a fair amount of data but once i remove the resistor i only get data up to the tps sensor, any ideas?

 

bring it again up.. had the same problem last week
when it was off I could measure data, when it was running fairly no data.

reason was, that at the back of the engine, the nut wasnt on the grounding cable.
make sure the cable is fixed there.


My problem now is that I get all the readings, but that tps stays 0.000 v when its connected to the quadrajet and 5.000 v when its disconnected from the q-jet

plugged on the q-jet measuring with multimeter shows correct readings
