I use a Toshiba 1902S Laptop with a Radio Shack USB to serial adapter. I use it with the OBD-II adapter for EFILive V6.4 Pro with no problems. LS1Edit V1.3 used to work fine. About 18-19 mins for a read, and about 2 1/2mins for a write. Since I have upgraded to V1.4 The read time has increased to about 36mins. Today I tried to see if it was a comms error so I set logging on and set show comms. When I tried to do a read LS1Edit only read the first 1% and then would back up and try to re-establish comms with the car. I tried both USB ports and different configs of the serial port but to no avail. I finally got it to do a successful read, but that was going back to my defaults with no logging and no viewing comms, however the read took 36 mins. and drained my battery to the point I had to put it on the charger for an hour before I could even start the car. Anyone else had a problem with LS1Edit V1.4 that wasn't there in V1.3? Also, I sent an email to the LS1Edit list and the reply from Ken was that they didn't do anything that would affect serial comms between versions. Well, SOMETHING is different. I am afraid to do a write with slow comms, I don't want to kill my PCM. I suppose I could break down and buy a PC to serial card but I don't want to spend $120 to find out that is no good either. My other alternative is to go back to V1.3
With the hptuners.com interface i can write in about 30 seconds and read in under 2 min. Why is LS1edit so slow?? Sorry that's of no help i guess but it shouldn't take that long to read i would think
Have you back-peddled to 1.3? I'd be curious to know if it's still happy. Seems like there have been a few reports of similar issues, don't recall if they were all USB adapters or not.

I am about to do that. I also ordered a Quatech PCMCIA to serial card. When that comes in I'm going to try 1.3, then 1.4 with the different configs and report back here on this. I am also about to pull the trigger in HPTuners, but it may take awhile to get that as I understand they are pretty backlogged. I also will need a way to write some old .ls1 flashes back to the PCM so I can get them into VCM. Sigh, progress... it's only money... The thing that burns me is I had ordered LS1Edit and hadn't even recieved it yet and read about HPTuners... :mad
I'd venture to guess your problem is with the Serial to USB adapter. I had the Keystone USB-serial that worked fine with EFI Live, but wouldn't work at all with LS1Edit. I bought the Socket I/O PCMCIA Serial card and it works flawlessly now.
Not that this helps..But you only need to read once..
Save the baseline file and edit from there..Just keep writing over the top.
1.4 does have some new failsafes install for trucks etc..that may bte the issue slowing it down.

Thanks RoadRebel, but since my reads were fine in 1.3 and much slower in 1.4 I am concerned that I will corrupt my PCM from a flaky write. I haven't done a Safe Write Only write, but I am more than a little concerned about it. I have a PCMCIA to Serial card due in on Monday so I will see how stable it is with that. I'd really like to feel warm and fuzzy with LS1Edit but up until now I feel like I'll betaking a chance every time I do a write until I can get the read times back to what they were. The other thing I wonder about is whether carputing will put in an option to use the fast read/write option so the reads and writes are much quicker.

One never wants to get *too* comfortable when doing stuff like this. I understand that you're saying that you've lost what little warm fuzzy you had.

That would indeed be nice, assuming it doesn't introduce new/different opportunities for failure. Their strategy has always been to err on the side of being conservative. I can't see it showing up w/o some nudging from paying end users.
