Read HPTuners Tune with EFILive. 2 Bar

I have EFILive. My Tuner/Shop has HPTuners.

(Tuning Speed Density)

The shop replaced my MAP Sensor with a 2-Bar (my car is a 1998 PCM with LS7 engine).
He showed me how he now has an extended VE table to accommodate my boost.

When I Read (with EFILive) the tune with my V2 that he has started (not yet complete ... still more tuning to do) in EFILive, I see the same size table, just the values have the same spread ... Like there is less resolution to the table I see in EFILive vs what he showed me in HPTuners.

Does EFILive yet have a custom OS (or some other mechanism) that will allow me to see the full 2-Bar MAP at it's full resolution in my 1008 PCM?
If not, are there any gotcha's to adjusting this table, down the line, from within EFILive?

An other information helpful on this issue would be appreciated. Thanks!

Is your tuner using a HPT Custom OS...? If so, then it is not compatible with EFILive and vice-versa (they don't know each others table offsets/formats).

EFILive does not have a COS for the 1998 PCM.

Many people swap their 1998 PCM for a 0411 PCM and then run OS 12212156... EFILive has COS3 and COS5 for this OS

( COS3 gives you 2.5-bar boost VE (and spark tables), COS5 additionally gives you TPS VE table, among other things like HO/LO adaptive spark still functioning when MAF is failed for Speed Density mode )

( since COS3 and COS5 are based on 12212156, the 4L80E trans segment from a 12212156 file can be swapped into the COS also, if you're running a 4L80E )

( note the PCM swap requires some harness connector re-pinning, and Fuel System segment swap from a 12212156 Express Van )

Thanks for the info, Joecar. I recall there was no Custom OS for 1998 when I bought EFILive the first time. I never understood why; I thought it could not be done for some technical reason.

<<EDIT: Before reading on, note as clarified later, an HPTuners Custom OS was in fact, programmed into the PCM>>

Because of that, I didn't think he actually programmed a custom OS, but he may have. I will double-check. They bought a two-bar MAP sensor and from what I understand, HPTuners then saw twice the table size. Before I left, I read the tune with my V2, and then opened it with EFILive, so I didn't think it was a Custom OS. But, being I know zero about Custom OS's, it very well may be.

Anyone bought this 2-bar? (GM part# 12580698)

When they bought this 2 Bar Map Sensor, I thought someone eventually (since I've been out of the loop for a while) figured out a way to get 2 bars out of the 1998 PCM, then EFILive would have it, too.

I'll screen shot the VE tables from that tune, and from the previous tune so you see what I see. But, instead of more rows like I saw in the HPTuner software, I see larger numbers ... but, not the same resolution/# of cells.

The top two images are the VE tables from an earlier tune. The bottom two are from the two VE tables he is currently working on. In it, you will see the higher range of values, but all stuffed into the same number of cells, lacking the resolution he was working with in HPTuners.

And this is the previous tune (table at the top in the above post), read in by itself.

So I guess I'm screwed trying to tune that file with EFILive :bawl:

If I leave it alone and never tune those tables, would it be I can tune other things like vary my idle, shift points, part throttle tables, TC, etc, even modify PE ... and write the tune to my PCM without disturbing what is in the VE table he put in from HPTuners? Or am I stuck with this tune forever until I can jump into re-pinning a 411 PCM?

Find out from him if he used a HPT COS or if he simply scaled.

Thanks, joecar ... I left a message for him. (Lunch-time)

im pretty sure all that he has done is just halfed the map resolution.

so if it were a metric map, 100kpa full atmospherics is now 50kpa.
