Default how long to download the pcm with LS1Edit.

How long does it normaly take to download the pcm with LS1Edit? I have been at it for over one hour and only at 50%. Second if you downloading the pcm to the computer can you disconnect without killing the computer??

Should only take about 30mins. If you disconnect it you could kill the PCM. Edit is known to fry PCM's.

Are you reading the PCM (PCM -> Laptop), or writing the PCM (laptop -> PCM)? Either way that is way too long. It's been a while since I used LS1edit, but if I remember, it somewhere around 8~10 minutes to read and 3~5 minutes to write. Way longer than the better tuners out now. You shouldn't hurt anything just doing a read, but with LS1edit anything is possible.

Yeah I have not used it for a long time, I dont remember it taking this long. I wonder why it is. I tried to disconnect but now the fuel pump is not turning on. So I started again and it seems to be going threw the steps. but i think i will end up having to take out the pcm and getting it reflashed. BTW im doing pcm -> laptop.

I don't think you will hurt anything reading... if the car won't start just do a PCM reset... the software puts the PCM into a mode where it stops listening to other devices... so sometimes you have to manually "reboot" the PCM by resetting it (fuse or battery connection) .. should be fine then

When I used to use edit years back It would take me 15-20 mins to read, and 10+ mins to write

It all depends on the year/make/model.

If you can find someone local with HP Tuners they could try to recover it for you.

edit took 12-15 minutes on my car. reading should not have hurt it. try pulling the battery cable for 10 minutes and let it fully reset itself.
