This is basically a request for VGT tables to be available for my calibration file from my 2014 Holden Colorado. Attachment 23264.
I hope EFILIVE can help.
Cheers
Scotty :)

Gee.... 88 views and not a reply from the guys at EFI Live..... thats disappointing... considering the bigger diesels are supported with these tables :(
Sorry Scott,
When you say the bigger Diesels I'm guessing you mean the Bosch based 6.6L Duramax or the 6.7L Cummins? Well they are different ECM's so you can't compare feature sets between different ECM types.
Re the VGT tables on the Holden Colorado, we couldn't find them I think was the issue :shock:
Pretty sure the E98 is smart enough that it doesn't need forced VGT positions via tables, it trims it to get the desired boost pretty well......but then I am not a tuner so don't take my word on that as the be all end all.
Cheers for thatQuote:

I was more interested in the tables for exhaust brake editing capabilities as we small folk here in New Zealand and Australia with our Colorado's, don't have an exhaust brake switch installed on our models like the American Colorado's do..... The VGT vein in the turbo is actually what does the exhaust braking by fully closing.
I do a lot of heavy towing with my Colorado so it would be nice to be able to maximize exhaust braking capabilities from actual editing of the tune.

I realise the ECM has the tables, but EFILive has not been able to locate them in the tunes.
Any chance of this to be looked into to find them?Quote:

Sorry Scott we don't get instruction manuals from GM on these things, reverse engineering is very time consuming and sometimes you just don't find what you are looking for. I'm not saying we will never revisit it but at the moment we have no free time to do so with getting the new hardware and supporting software ready.
Disappointing …….but thanks for your repliesQuote:

Other parameters are impacted by boost, optimal timing, for example, is influenced. I have wanted to visit this platform also, but I would wonder what I could accomplish.
heres about 30 minutes work for the vgt tables that hpt present.
load these into a cax file and have a play and report back. this is for OS-55491998 also works for the custom os based of this.
