I'm having some issue after I put hotcam/head work/headers on my 93 Z.
She has a stumble at idle, stumble under light throttle and pinging/detonation under load. I have the Pcmforless chip also.
If you know where I can purchase this tool, please let me know.

 

I believe tts datamaster has software you can download to your lab top to monitor it. You'll also need to buy the cable that connects your computer to your aldl port. The software is cheap but the cable is $100 I think.

Purchase an interface cable, get a laptop, and download Freescan or Datamaster.

Or you can get a Scanmaster...

 

It wont work, so I hope you were joking with that


I got Freescan but no cables so its on my p/c, it looks like a cool program, like if it works it can tell you a lot of info. Its works for our 93s. You can't alter any thing but you can look to see whats going on, that alone will aid you greatly on tunning those chips.
