LMM: Problems with new EFI version and LMM

[JD4440]

I tuned a friends LMM with some tunes from Danville. Stock truck - DPF, egr intact. I rarely ever use my V2 so it was still on 7.5.5 and wouldn't open. No problem there Mark had me DL the latest version (V8) and I tuned the truck w/ the DSP5.
On now to the initial problem: He's experiencing what he describes as the turbo cutting out and excessive smoking during highway driving with a bit of a load. Also he cant tell the tunes are changing.
And my problem: I can't get the scan tool to work on this V8, it has my whole EFI screwed up because I have to use the old scan tool and the new tune tool. To add to my problems I can't view the tune to see how the egr is set up and for some reason the scan tool says the DSP5 pids are invalid on the LMM but I can view/ log them on my LBZ, therefore preventing me from seeing if the switch is working and what tune it's on.
I returned it to stock last night and this morning got a call that he had reduced engine power (DPF is deleted). I flashed in a temporary single tune from a friend to get him going, but I really need to get the tuning he had working. Thanks in advance guys

Download the new V7.5 and use the scan tool to datalog.

Was the dsp5 tune scripted?

Unplug his EGR valve, I'll bet it's cycling erratically

You said Dpf/egr intact, but now its deleted? Have you called Mark? Maybe there was a miscommunication on what tunes he needed.

no idea. I sent him the stock tune and he sent me what I have now

I had read that, but thought if I did it might blow open ??

The email I sent to him said all stock with no dpf. I plan to call him as soon as I get a few more min. First thing is determining if the switch is working I guess.

Put a blocker plate in the EGR. I've tried leaving the EGR in, and they will roal coal without a blocker plate installed. The boost will pop it open and flow without a blocker plate installed regardless of what the EGR is set for.

Yup got me a time or 2. Won't do them without a blocker plate

I'll get one coming, I figure it's my safest bet. Mark told me to unplug it but It won't hurt to go that extra step I guess. Is V7.5.7 build 245 what I need ? I have build 246 from the V8 download and that's what didnt work for scanning the DSP5. Somethings wrong with the PID files, I only have 56 seems like there were 100+ before. And the DSP5 pids still show not supported.
