Car Gauge Pro can read CMP

[Chimneyman420]

Oh, so you have it showing the CMP Retard but the value itself isn’t changing?

Correct that's what I can't figure out.

It may be something with the OBD adapter then.

Just to make sure, you loosen the distributor hold-down clamp, grab the top of the distributor, twist, check the reading and retighten. The ear that the distributor cap screw goes into will nearly touch the upper intake manifold when it’s set close.

Do you have the P1345 code showing?

Yes and yes

What brand adapter do you have? I have a BAFX brand, it works well enough but lately disconnects fairly frequently. If you’re getting the same result from the two apps, the adapter may be the problem.

What a pain, huh.

Yeah it is. The first one I got was a $5 elm327 knock off clone that wouldn't connect to ecm. Then got one from OBD Innovation. It connects and reads other pids in live data. Just recently purchased the blue driver but doesn't connect to dashcommand. Haven't tried it car gauge pro

Mine was weird at first. Had to restart the program

Sorry been so long to give a update. I got the bafx adapter and was able to read Cmp retard. Ended up buying a new distributor and installed it. Made sure I set tdc on compression stroke. Needless to say I still can't get it right. Closest I've been able to get was +6. I'm starting to think that my timing chain maybe stretched a little. Haven't checked yet but will give you update when I can afford to do that.

As an update, someone on my YouTube channel said it didn't work on his 96. I'm going to try it on my brothers this weekend.

Did it work trying to do my 96

Bringing old thread alive again to see if anyone with a 96 had any good results with reading their cam retard??

I can imagine having problems when trying to use some consumer-grade scan tool. I have trouble believing there's an inherent problem with the vehicle computer.

In other words, it's the tool, not the vehicle that's the problem.
