Scanner Tool To Set The Timing????

...just rev above 1k after every adjustment so the sensor picks up correctly.

Shim the throttle, so you don't have to mess with it, while adjusting. I think I used my little Stihl flatblade screwdriver.

You want to be 1000-1200 RPMs per spec when setting it up.

OK, Shall try again tomorrow.

The other software I have used seemed more intuitive when trying to connect to the vehicle. I'll look more closely at Torque Pro.

It is interesting that I have removed this distributor in the past and replaced after setting to TDC. Now for some reason no matter what I do it falls on either side of the set mark.

Thanks

Just used dash command and a bafx bluetooth dongle to do mine. Had to buy the $10 GM add-on for dash command, but it did it just fine with no issues. Super easy to do.
Get someone to hold it at 1100 rpm while you adjust the distributor and watch the offset.

does this need done for 96? im seeing that 97 and up are non adjustable distributors. i tried the torque settings it didnt work, so i downloaded dashcommand and added the gm pid for an extra $9.95 and theres no option for any camshaft Retard timing. i drove the truck around the block the check engine light never came on. i aligned the distributor the same way it came out and was on cyl 1 TDC before removed so i installed it same way. not sure what to think about this.

It's should be something like CMP Retard or CMP Offset. It's not timing. The PCM adjusts that.

yeah im not seeing it. I went to DATA Grid and tried adding a PID to log, looked for both of those and nothing, went to GAUGES tried adding a gauge and looking for both of those. not sure why im not seeing it. im not sure it downloaded the extended PIDs. i went to account and purchased it but nothing really happened. it shows that its purchased.

Here is where mine was. Mines a 98 and using an Android tablet:

Data Grid
PIDs
Add PIDs
General
GM.Engine.CMP_RTRD[•]

There were two of them, not sure what the difference is.

i just checked again and there are no gm specific PIDs. I tried while connected to vehicle and when not. i wonder if i have to be connected to wifi for it to work? it checks for wifi while connecting to vehicle. i emailed them to find out why.
thanks for the assistance so far.
