1982-1995 GM ALDLPC hardware and software for diagnostic code reading and real-time data logging on the cheap. Or at least a whack at it.It's a proprietary GM PWM TTL level Serial communications protocol. It was not standardized even loosely within GM divisions. It varied greatly by model, nameplate, year, and even engine choice.Mr Goodwrench used the Tech I and later the Tech II to communicate with these vehicles. If you can find a working Tech I or a real Tech II they have more functionality than any aftermarket solution depending on your needs.The Tech I is all but extinct (I haven't seen one for sale in over 2 years).
Most of us can't afford a real Tech II and those are getting scarce. If I could afford a real Vertronix or HP Tech II I don't feel confident that I could weed out the Chinese counterfeits. 1959 M35A2 LDT465-1D SOLD1967 Dodge W200 B383, NP420/NP201 SOLD1969 Dodge Polara 500 B383, A833 SOLD1972 Ford F250 FE390, NP435/NP205 SOLD1976 Chevy K20, 6.5L, NV4500/NP208 SOLD1986 M1008 CUCV SOLD2000 GMC C2500, TD6.5L, NV45002009 Impala SS LS4 V8RTFM.

$5.00 US. Capable of using free and paid plugins and several other features not in the LITE version.You should enable extended GM PIDs. From the main screen press Menu-Settings-Manage extra PIDs/Sensors. 'Menu-Add predefined set-Pontiac/GM/Opel/Vauxall'.
You just added all Pre-Defined GM PIDs to the available PID list. Very Useful FREE Torque plugin.After you install this goto Menu-settings-plugins and tick the 'Allow plugins full access check box' TorqueScan will show all the known sensors that it can read from the installed list of PIDs along with the realtime data being read. That's useful enough, but if you want some real magic goto Menu-PID Scanner to scan for additional PIDs while you're on a longer drive. The PID scanner says it will take a long time. Be sure your device is plugged into a charger. It's worth the wait. The PID Scanner function of TorqueScan will compile a list of all available extended PIDs on your vehicle including those not in the pre-defined list.Note: I use TorquePro with TorqueScan.

There are several other OBD II apps in the Play Store. I don't use them so I have no idea of their functionality. Interfaces Bluetooth & USB 1982-1994 ALDL 12 terminal moulded plugs1994-1995 16 terminal J1962 moulded plugs.1996-2005 OBDII and 2006 and later J2411 CAN with 16 terminal J1962 moulded plugs.NOTE Commercial ALDL, OBD II, and even OBD II/J2411 CAN interfaces are again fairly inexpensive. Around $55-$100.ALDL 12 & 16 terminal Interface. Bluetooth to ALDL 12 & 16 terminal moulded plugs.Note: 1320 electronics is the developer of ALDL Scan. Their interface has COM status lights and easy configuration dipswitches. Their USB-only cable has user selectable switches to select data from pins D, E, & M.
The Bluetooth adapters data pin settings are internal jumpers with a default of E & M that covers 90% of users and possible custom configuration of data from pin D by request. Bluetooth to ALDL 12 & 16 terminal moulded plugs.OBD II & CANBUS J1962 InterfaceIt's worth noting the Chinese ELM327 Bluetooth OBD II interfaces are very very cheap. The price should be a red flag.There are more than a few stories of damaged PCMs using the super Cheap Chinese OBD II devices.They usually have various issues some large some small. They seem to be luck of the draw. You might not get a lemon but you are very likely to.
If you buy one be SURE you can return it if it doesn't work.Don't ask for guidance here making the Chinese interfaces work. Most are full of poorly copied stolen chip designs in either the ELM327 PCM ECM connection or the Bluetooth radio or both and there's no way to tell what you're getting.IMHO the cheap and super cheap Chinese interfaces are not worth your time. Smart Bluetooth WirelessGoes on sale for $79.95 fairly often. Multi-protocol interface covers OBDII GM (J1857 VPW) & SAE J2411 Single-Wire CAN (GMLAN) and others.Note: TorquePRO; This is the best adapter if you want the fastest PID read speed. Read speeds can be as fast as 100PIDs/sec over Bluetooth (Tested on a Galaxy S4, CANBUS protocol).
This device also offers security to prevent unauthorized use.Hopefully this provides a good jumpstart to your search. 1959 M35A2 LDT465-1D SOLD1967 Dodge W200 B383, NP420/NP201 SOLD1969 Dodge Polara 500 B383, A833 SOLD1972 Ford F250 FE390, NP435/NP205 SOLD1976 Chevy K20, 6.5L, NV4500/NP208 SOLD1986 M1008 CUCV SOLD2000 GMC C2500, TD6.5L, NV45002009 Impala SS LS4 V8RTFM.

I have used TunerPro and WinALDL with a laptop to read my old ECMs data. They work very well.I've used both of them. They work very well. I even donated for a TunerPro RT license.Right now is the time to get a good Windows XP laptop with USB ports to run this kind of ALDL & OBD II software. There are so many of them dropping on the used market that the prices for complete, tested, ready-to-go units are between $50 & $150 with tired batteries.You want them to have tired but working batteries because it proves the charge circuit works. 1959 M35A2 LDT465-1D SOLD1967 Dodge W200 B383, NP420/NP201 SOLD1969 Dodge Polara 500 B383, A833 SOLD1972 Ford F250 FE390, NP435/NP205 SOLD1976 Chevy K20, 6.5L, NV4500/NP208 SOLD1986 M1008 CUCV SOLD2000 GMC C2500, TD6.5L, NV45002009 Impala SS LS4 V8RTFM.

It'll be easier to answer your questions.And please let us know if and how your repairs were successful. Great info!I use the All-In-One tool along with their OBDI, OBDII and MEFI-4 cables as well as genuine GM Tech II scan tool to talk to both OBDI and OBDII. I use the Tech II most often but I use the OBD Diagnostics when I am traveling with limited room to carry a big Tech II.As far as software for the OBD Diagnostic, Inc. Cables I use ScanTool.net software, DigimotoLite, TunerPro RT and a few others. One of these allows for OBDI data logging as well.
I think it is TunerPro RT that will allow me to Data Log. I have no tuning ability and I don’t want any. Tuning is an art left to those that do it on a routine basis. All of these software packages are free and have the ablity to monitor data but cannot command any actions like a Tech II scan tool.
