LLY: EFILive DVT's...broken...?

For what it worth ... Ben thought it was Cyl #7 with EFI Live but with the Tech 2 it was actually Cyl #3. From the prevoius confusion that the gasser guys were having ... the difference was using the firing order vs. cylinder order.
My stab in the dark on the Duramax issue -
When you DVT Cylinder #7, EFI Live is actually going through the trouble to look up which cylinder it really is in the firing order and thus turning that one off ???????? Cyl #7 is the 3rd cylinder in the firing order (1 2 7 8 4 5 6 3), and thus it turns of Cyl #3 and not Cyl #7.
This is a total wild azz guess ... but might explain why it did what it did. And YES!!!!!! I totally agree that this is a MAJOR BUG and needs to be fixed ASAP!!!!

The Scan Tool information provided by GM is what we've displayed in our software. If this is incorrect or if the terminology is incorrect we need to fix it.
We have asked both in the thread on our forum, and privately to a number of users for further testing so we can be sure what we modify is for the benefit of all users, however that information hasn't been forthcoming.
Until we can disprove GM documentation with evidence (not hearsay and banter) we are not in a position to make changes.

Ok sorry guys, just kinda frustrated here but oh well...
So 3 hours away from home last night I lost an injector. Started clacking/knocking/POURING white smoke. 25 miles after I filled up with fuel, go figure.
I had my truck towed to my buddys house in burlington cause he has a good sized garage. I didnt bring my tech 2 with me (stupid), so I used the DVT's in EFILive to try to diagnose the problem. I guessed it was an injector because the noise was an upper end "clack" and not a bottom end "knock", and I have no blowby or any other mechanical problems. Thick white/gray smoke is obviously fuel.
So I use the EFILive DVT's to shut off injectors. I get to #7 and the smoke goes away and the knocking immediately stops. YAY!! Found the problem. So then I call up Schulte (huge thanks, put it on my tab of things I owe you for bud) and he meets me halfway between burlington VT and home in CT... so we each drive about 2 hours, him a little more. He brings me a set of good used injectors to get me home. I drive back up to burlington...theres no heat in the garage so at this point ive been working all day in ~38* replacing injectors. I swap my 40% tip over to a good used injector and put it in. Still knocks, no change. So I think ok maybe the tip is clogged, so I put in a good/used/stock injector. Still no change, smokes/knocks.
So I pull up efilive again, balance rates are all over the place. Use the DVT's and shut off injector #7. Smoke/knock stops. WTF!!!!! At this point its getting late and I just need to get back home because I have customers trucks in the shop tieing up the lift that I need to get done, business stuff, etc...
I call ScratchRob and he comes with the gooseneck and his LBZ to pick me up...I think he ended up driving 700 miles between getting his trailer, driving to VT, and driving back to my house. I owe you too, we agreed on a bazillion dollars compensation and a set of BT DieselWorks twins.
So I go mess around with my truck this morning. This time I grab the Tech 2 and discover something interesting.
I fire it up, knocking, smoking etc. I go to the injector shut off/cylinder power balance thing in the Tech 2. I shut off injector #7, no change, still knocks. Shut off injector #3....KNOCK STOPS. Shut off injector #7 with EFILIve DVT's, and the knock stops.
Interesting.... I hope I didnt work all day in a 40* garage and make two of my friends drive hundreds of miles all because the DVT was telling the wrong injector to shut off...???
Ben
Ben, I've noticed similar issues comparing my SnapOn Solo plus and EFILive DVT. The difference being with Balance rates and showing the actual cylinder. I don't know though, I need to do it again with detailed discription.
Just an update to this thread given it's been idle for a month, we are yet to find someone who is able to assist in controlled testing to prove/disprove this issue.
The tester needs to have access to both EFILive and a Tech II. If you are willing to assist, please email me cindy at efilive dot com.
We are willing to investigate and make changes to our software, but only if we have adequate test results.
Cheers

What exactly do you need tested Cindy? After Josh H posted i kinda feel like a ass........... if he is correct
But I truly want to know, What is the real deal.And honestly I dont want to rely on what DURATOTHEMAXI says.
Ok,I checked balance rates and found what i suspected a bad injector. I swapped the injector with a brand new injector but the modded tip that was a 40% over
The tip was swapped by a qualifed BOSCH dealer and tested at low pressure only
After swapping the new inj with the used tip I had the exact same balance rate ( +6 )???WTF I did a compression test before the inj swap and di not see any reason for compression being a issue
I then after talking to the SELLER of the 40 overs injectors. I purchased a complete new set of 100 over injectors and the problom went away
was it the injector or just simply me replacing the wrong injector

The ultimate aim is that we want to map the 8 cylinder/injector numbers in the Tech II physically against the engine and then marry them against what we have in EFILive (which people are saying is different).
Once that test is done, we'll determine what action is needed.
Customer feedback is what drives our product, however we can't implement change unless we can backup that feedback with demonstrated fact. It makes no difference to us who delivers the message, while it is heresay nothing will change.
We have had an offer of assistance since my post a few hours ago. Hopefully we can update this thread soon with some results.
Cheers

Cindy,
I have access to LB7, LLY, LBZ model years and have a Tech II with a Candi Module.
Please email me or PM me with the test procedure you need done and the data you need and I will get it done for you in the next week.
Tony
Tony if it's not a conflict with the crew at efi live could you post your findings on here. It would be nice to know how to compensate untill they make an update, if an update is indeed needed.
Hey ben this is josh from canton with the corvette. Sorry to hear that your still having trouble with your truck.
hey whats up! Still have the vette??
Simon, you know much less about all this electronics/duramax shit in general than I do so buzz off.
when I get the engine back in my truck, I can put that known-bad injector back in each cylinder and then go through with the tech 2 and map it out.
I'll follow up with the testers and see where this is at.
Ben, I'm confused - you started this thread in November, wasn't it your truck?
Cheers
Cindy
Yes, I broke a crankshaft in august, my truck was parked until end of october, when I desparately needed it to move a lot of stuff down to New Jersey for this huge event me and my friends were running...so I borrowed a stock engine from Schulte, and threw that in my truck. 2 weeks later Schulte needed it back to give as a core to someone, so I pulled it out and gave it back to him, and my truck has been sitting without an engine ever since [beginning of november].
It was during that 2 week period when my truck had the borrowed/temporary engine that the injector went bad (go figure) and I discovered the discrepancy/error in the EFILive injector DVT's.
So from august to end of october it was parked, then it ran/lived for 2 weeks, then got parked again and its still sitting there today.
It seems like you of all people would have your truck running by now. Come on Ben spring is around the corner.
