I have my new EFIlive stuff. I was out in the truck playing around. I can't seem to get it to scan anything. It says it can not connect to the truck. No big deal cause I really want to tune. So I open the tune program and the first thing I do is read my stock pcm to save that program. No problem. It reads fine and I save that file. I load back in the low setting with the ppe and read that also so I have something to compare to. That went just fine also. I then return my pcm to stock. I want to load the ppe back in using EFIlive. I go to program and it say's I'm not licensed to do that. So I figure out how to use my license, and all of the sudden the EFIlive won't do anything. It say pcm type unknown or some other gibberish. Then it say pcm not detected. Now I cannot read the pcm either. I'm a little frustrated at this point. Anyone out there have this problem? Please help...................:help:

Try unplugging the Flashscan from the ODBII port of the truck and close the EFI Tune program. Reopen the program and try again.

Tried unplugging several times and also closing the program. Nothing has made a difference yet.

Try a different USB port? Worked for me.

Make sure the scan tool is not connected if it is open, the button at the upper left of the scan tool should be green.

If you do not disconnect the scan tool from the ECM it will give you an error message.

If you do disconnect the scan tool you need to license your ECM to Flashscan to load any changes, once you license it that is it you have used a license.

If you want to monitor real time data you need to click on the YELLOW button on the Data screen in the Scan window or the Red button records....just ask McRAT.....):h

Thanks for all of the replies so far. All of the suggestions so far I have tried. Changing ports, the yellow button, licensing, and stopping the scan tool. What really bothers me is that I was reading the ecm just fine until I licensed it. After that I could not do anything. I've rebooted, closed programs, used different ports. The error messages jump between cannot connect and can't determine type of pcm, ecm.

I assume you have selected DURAMAX LLY as the PCM you are trying to read ????

Yes, I have the duramax lly selected. If it had never worked, I could understand that. I have read the ecm 5 times. All of the problems started when I licensed the ecm.

Look under the help tab and see what the versions are, have you tried a TEST FLASH YET ??? it simulates a flash but does not actually flash the ECM.

Have you installed any aftermarket equipment ??? DVD player, XM or Sirius or aftermarket radio ????

With the IGN on and connected to the vehicle, when you press the button circled in Red, does it show a valid VIN etc as shown in my screen shot?.
Also, when you go to Help >> Flashscan PCM Licensing, it should also show you that License #1 is used.

Once I licensed, I tried the test flash and that failed also. I Have an alpine deck with aftermarket xm. I have heard of some issue with some aftermarket equipment. But, it worked until I tried to license it. I do have an adapter that still chimes and stuff when the door is open and so forth.

If you were able to read the ECM 5 times then there is probably no issues with data bus problems, if you missed it, please see my post a few up from this one.

It appears to have my VIN on that screen shot. When I tried to read again it says pcm did not accept bootloader. EFIlive could not unlock pcm. I went to the screen where you can lock the pcm and it says that it has a standard key and that it is unlocked.

It also shows that I am now using my first license. I did all of my ecm reads before had licensed the stuff. After that, nothing.

Mmmm, O.K.
Go to the folder -
\Documents and Settings\Mr Man\My Documents\EFILive\V7\Bug reports
Delete all the .blx files currently in there.
Then try to read the ECM again, when / if it fails again (won't accept bootloader) then please email me the .blx file that will be created in that Bug Reports folder, that will show my why the ECM is not accepting anything.
Mail to - ross at efilive dot com.

Reading an ECM does not consume a license, only when you try to write to the ECM.

Ross, I will give that a try and let you know what happens tomorrow. Thanks for your help. -Verlon-

Me being really ignorant about this stuff BUT is there any chance it has something to do with the PPE programming and clocking you from doing something?

Sorry if that is just completely stupid and I'm WAY off base. Just trying for a shot in the dark to help you out.

Good luck!!

I pulled the ppe out so my truck was back to stock before I tried to flash my ecm. Once you go back to stock from the ppe, your ecm should have no trace of it.

I Have an alpine deck with aftermarket xm. I have heard of some issue with some aftermarket equipment.

Verlon, at this stage from looking at the bug report files you sent it appears as though something is interrupting the process. I have no explanation as to why this might only be occurring after licensing the ECM.

If you can disable the aftermarket radio gear (pull the radio fuse etc) then retry we can narrow it down. Unfortunately what we are finding is some aftermarket gear that connects onto the data bus does not conform to GM's standards and simply never shut up when told to!.

Ross

Yah, it sucks. I am prepared for a lifetime of pulling my radio fuse to flash the truck because of the P.O.S. PAC adapter...

Well, the truck started up again. Ross, I will go at it again in the morning with the radio fuse pulled and see what happens. Thanks for the help.:o:

I don't have my manual handy. Which one is the radio fuse? Is it under the hood or is it on the panel in the cab?

Under the hood.

Well, I guess I will be stuck pulling my radio fuse from now on.:mad: Once I did that I was able to flash my ecm. Hopefully I won't have to pull the fuse when I want to scan live data. Thanks for all of the help. -Verlon-

No, you'll be fine for scanning. I now carry a needlenose in my center console so I can swap tunes away from home.

I need to pull the fuse for tuning, but NOT for scanning.-:t

Guys,

Unfortunatley I don't think there is much we can do about this problem.
You can bet if these were supplied to GM as OEM gear they would behave themselves on the bus, I wonder how the dealers go with all this stuff now?

I remember in early testing Trippin told me one of he's aftermarket devices even screws up TechII when 'scanning'!!.

Anyway, glad it's all working for you now.

Cheers,
Ross

Ross,

It's not YOUR fault we put aftermarket sht in our trucks that doesn't comply :cool:

Now hurry up and get that new revision out for the Dmaxes!! :muahaha:

Using a PIE or Soundgate XM adapter to integrate a Pioneer XM receiver into my stock head unit would cause the Tech 2 to go crazy. Sometimes the Tech 2 would just lose the connection. Other times while scanning it would cause the engine to actually stop running for a second and then restart while driving on the freeway. :eek: One time the Tech 2 just killed the engine on the freeway. -:t

I never could get "any" handheld tuner to load at all with the XM adapter plugged in. :(

I ditched the XM adapter and Pioneer XM receiver in favor of a factory XM kit when I started playing with EFILive because I flash two to three times a day, and pulling the dash apart each time to unplug the adapter was alot harder than pulling a fuse. Pulling fuses never worked for me.:(

Didn't help my truck any :p::lol:







Sorry about the off topic but I coudn't stop myself

This may be way off, but would it be possible (For those that need to pull the radio fuse!) to reset the time through software? IE: once the programming is complete, switch over to scanning,replace the fuse, and have an option to set the time on the radio. Just thinking out loud!:eek: (Maybe it could set it to the computer time.)

Sounds like maybe an in-cab switch to disconnect the radio instead of pulling the fuse might be easier.

I thought about that. I'm just a little slow on the implementation...hehe. :cool:

because I flash two to three times a day

Better watch out Guy, the cops will get you for that.):h

He did look comfortable in the back seat of the cruiser Saturday.

Could the ecm ever be flashed to many times? I wonder if its like a hard drive and just one day out the blue give you the bird?

I think they quote about 10,000 before the flash chip gets flakey.

I guess I won't ever have to worry about over flashin then, Thanks Ross

I think I'm half way there. :D

so did the guy posting his issue get it resolved? I seemed to have missed that through all the side stuff in this thread.

If so, what was it??

From my own experience, you should have an extra ECM regardless.

Even if there are no software glitches ever (remember a computer is only as reliable as Bill Gates will let it be) there are always stupid things that can happen. Static, dying battery, accidents, etc.

No ECM means poor performance, as these trucks are very hard to push. :D

I believe so, the problem was an aftermarket audio adaptor.

Thanks, that is what I was beginning to think. Just must have missed the part where he said that was his problem. Only seen where others had mentioned it being a problem for them.

Thanks and glad it was figured out.

It did end up being my radio. I pulled the fuse and didn't have a problem after that. I'm thinking some kind of in cab switch to kill the radio will make this much more convienent.
