I was working on some of the fuel settings yesterday that got out of the new Master EFI Tuner book. The car was idling fine for a couple minutes, then I hit the gas & it died fast. I called it a day there. When I tryed to do some more tuning today my computer would not connect to the PCM. I tried to put an old tune on & still no connection. It will not read it either. The car would not run, the fuel pump would not come on.
I put on an old PCM I had & it started up.
Did I kill my PCM?

Here is a copy of the data run

 

We unbrick PCM's and we Clone PCM's. A cloned PCM will allow you to tune 1 vehicle with 1 license

 

I may take you up on this. I have 2 PCM's & both had mail order tunes, so I am not really sure I want to do another one. Neither one got me driving, they just started engine w/ rough idle. I have 1 PCM that still works. I need someone to do a dyno tune, but I have not found any here in Fort
Wayne.
Does your mail order tune do more customization? I have a bigger cam & shorty headers.
Thanks
