Killed my 2nd ECU. WTF

[Round Rock TJ]

For my second ECM....

Downloaded the latest and greatest. Pulled a fresh tune off the P12 using v8. Opened it up in v7 and changed a few small things. Opened the tune back up in in v8 and simply saved it. Opened it in v8 and downloaded it. It went without issue. Turn the key and nothing. Nothing can communicate with the ECM.

This is BS. Im so pissed. So now what. Drop some more money on another ECM and license.

Give the ol error $0280

When I try to download in v8 it go through and says programming. But the timer never starts. This is all it does.

I tried it with a battery charger hooked up and even removed some un-needed fuses to see if it makes it any better.

The 4th light on the V2 blinks.

What versions of V7/V8 and what V2 firmware...?

[Round Rock TJ]

OK it might be something with the voltage. While its trying to program the dash volt meter drops down to 9. Has anyone seen voltage problems give these kinds of issues?

[Round Rock TJ]

What versions of V7/V8 and what V2 firmware...?

The latest and greatest. I downloaded all of them today. Updated both firmwares as well.

2.07.04
2.07.29

Build 197

I pm'd Tech Support.

The 4th light on the V2 blinks.

If its flashing about 4 times per second, that indicates the PCM is in dead-poll which just means the calibration is gone (i.e. erased) and has not yet been programmed back in.
The voltage at 9V is an issue. It needs 12V to program the flash chip.

All I did was download the tune in high speed mode. I had it unchecked because high speed never worked for me in the past on this P12. I thought I would give it a shot and it worked. It took 35 seconds. Im used to the 11 min thing.

Sorry about the red faces. All I was trying to do was return the car back to stock to sell it. I had to tell the guys to come by another time. I hope I did not scare him off.

Thanks Guys

Glad you got it sorted in the end. Unfortunately the older pre CAN bus vehicles can be pretty sensitive to interrupted flashing. If you have ever used TIS (GM's dealer programming system) it always says pull 'x' number of fuses before flashing. Whilst you normally wouldn't need to do that with EFILive nothing is a 100% guarantee with the Class 2 bus vehicles.

U find what was causing the low voltage???
