V2 will not communicate with LS1A PCM's

[Schwanke Engines]

I have a full stream for the LS1A, B, E40, E38 and basically everything GM makes with a V8 in it. After this last update I for some reason cannot read, flash, or even connect to an LS1 A PCM. I have 4 of them that a customer needs flashed and cannot do anything at all with them. I just did an E38 and 2 LS1B PCM's this morning, but when I try any of these LS1A's I keep getting a bootloader rejected error and a reason is no reply. Is the Firmware not updated properly or is it another issue I am not seeing?

We are investigating the LS1A connectivity issues with the V7 software.
Until we figure out what is happening, you should be able to save your LS1A tun files as *.ctz files and flash them using the V8 software.

What firmware/bootblock, are you running the latest V7.5 and V8 software from EFILive.com?

Got beat, guess using V8 is the way to do it. I try to only flash in V8 if I can help it, the flashes are much quicker for me!

Any updates on fixing this issue?

I tried this and converted a cal I have used for a year on these PCM's for TA2 and I get this error code "Script exited with code $06FF: Checksum failure." It comes up at the very end of trying to flash the PCM. When I read the PCM after flashing it and open it up in V7 it appears to have flashed, but want to make sure that the calibration has actually flashed into the PCM as I have never used V8 for anything other than updating.

What is the build version of your V7 and V8 software...?

What is your V2 firmware version...?

[Schwanke Engines]

Everything has been updated to the newest software and firmware, thus the issue I am having.

[joecar]

After updating did you re-program the BBx config ("Program All")...?

A new release is scheduled for today with the following fixes...



Added support for E67 OS 12622275.

Added validation to EFILive Explorer that warns the user if they attempt to copy an non-remote licensed *.ctz file to AutoCal.
Added "Remote" display column in EFILive Explorer and EFILive Scan and Tune file lists that displays the remote AutoCal license number to which the file is linked (if any).
Fixed "Created By" field not auto populating with user's details after a controller is read.
Added CVN History display to FlashScan.
Changed NO2 to N2O for FPE.
Fixed DMA PIDs not being valid for LBZ, LMM and LML during BBL.

I have been able to reproduce the fault -again, it appears to be the same fault that was supposed to be fixed in the latest update. It appears the fix did not make it into the update. I'm trying to track down why the fix did not get into the update.

I now have the same issue with the LS1B PCM's, went from trying to fix one issue to creating another.

[joecar]

I alerted Paul to this problem.


V7 seems to fail; V8 and BBR/F seem to be ok.

Tried to read and flash a LS1A today with V7 & V8 failed with both.....Took the pcm out of car and could read it and flash it with V7 and V8 on my bench harness. I could connect the scan tool to the car and scan but it wouldnt read or write.

Update to fix that is available here:

Latest update fixed LS1B issues, I will check on an LS1A later today to be sure it works with that. Thanks for fixing this issue quickly.

It's not fixed all the way, I can't flash ls1b now but could before update.
