VE Commodore - whats the tuning situation?

[35R]

Are the mainstream tuners all doing VE Commodores now? How are they tuning them? I've done some reading on the HPT website regarding speed density tuning, it's a bit of an eyebrow raiser..

Are most of the tuners doing maf tunes or speed density tunes? Any thoughts on which tuning software might be mor suited?

Is EFILive set up for VE Commodore?

Also, I think the VE commodore has two "post cat" O2 sensors now correct? Has anyone done exhaust work yet to VE's? I hear that high flow cats are causing a few "issues" for those "off the shelf" exhaust installers..

Questions questions...

thanks for any tips or info guys.

Sam has bought a VE SS, and you know he will fiddle with it.:) The GenTT mob have a VE with their kit fitted, you may want to trawl their section on LS1 and see what they did/have done to tune that?

Yes the exhaust has post cat O2 sensors, which means after market cats need to be setup or it will throw codes.

It will be very interesting to see how people go tuning VEs and then the owner trying to bluff Holden on a warranty claim as the car logs and keeps a lot of data that is accessible through the cluster.

Interesting. When you say cats need to be "set up" what does that mean?

Yeah this is where I run out of puff, all I know is you cant just bang on an exhaust like a pre-VE, you need to plug the laptop in and have a fiddle. The PCM is set up to expect the change in exhaust gas caused by a factory cat. So if you change the cats to a high flow jobbies the readings before and after will not match the factory presets so the PCM chucks a wobbly.

The little I have been able to glean is that relocating the O2 sensors will trip the CEL, which means keeping std cats or their equivalent in the factory location - meaning shorty headers and cut std cats with slightly larger pipes welded on. Some tuners are getting around this by turning off the CEL or whatever sensor tripped it, via the limited software that is available.
I recently heard on the rumour mill that tuning software was released 2 weeks ago and is now available but I havent confirmed this with Sonny or anyone yet. I am keeping my ears to the ground on this as I have a personal interest in it.

I think you can tune E38/E40 with HPTuners, anyway i would hazard a guess some maybe turning off the CEL for the secondary post-cat O2's - assuming they do nothing except for checking the cat is "working" for emmissions reasons?

We have done a di fillipo system on a VE using the orignal cats no check engine lighjt issues, at this stage only the original cxats are being used as there is a few issues that are being looked at,as far as tuning,i will tuning quite a few VE's shortly and give some feedback though i have been doing a heap of logging and theres some eye brow raising things i have seen in the logger :)

L98 for you as well a little later in the year :), can you elaborate in layman's terms about some of the eyebrow raisers you've seen in the logger? BTW, what sort of increase did the DiFillipo's produce - 15 to 20 rwkw I have heard but dont know if that is accurate?

Anywhere between 15 to 20kw,at this stage i cannot comment on this eye brow raiser stuff :) though will wen th time is right :),had a VE in today on its second box and third cltuch :eyes: going in for another clutch next few days,though this time perhaps a tex :)

Thanks Sonny, geez I'm a bit concerned now, cos you are not the first one to tell me the VE's are going through gearboxes and clutches........and my g'box doesnt feel quite right :(

Mate don't worry, the car Sonny mentions here is the same car I mentioned on LS1, Sonny was gracious enough to have a look at the car and give feedback to the owner. Yes it has issues and when its all said and done and the owner is happy I'll post the full story. What I will say is the car had a clutch issue and the replacement of that should have been the end of it.

[Brockfan05]

Thanks exploder, but the LS1 forum hasnt been the only one I've heard about. Was talking to some of the traders at Summernats and there were 2 separate cases of gearbox and clutch failures in VE SS's.......

Stayed tuned guys as i have 3 VE Series commy's booked in,

1 - SS-V Cold air intake / Di Fillipo 4into one long tube headers,euro cats,dual 3inch system / Tune

2- E Series R8 delivered via tow truck from dealer with zero km's, TT Kit / Dual 3inch system and fuel system / Tune

3- E Series GTS Cold air intake / Di Fillipo 4into one long tube headers,euro cats,dual 3inch system / Tune

-Will keep you all informed on the progress of these 3 as they come,been playing with the VE software,it is at the early stages yet,as at this stage tuning a cam in a VE is no where near,know of 3 VE's that had cams put in and pulled out as fast as they went in ! at this stage HP tuners have the VE software.

Unreal Sonny ... can't wait to see the results of these. It doesn't take long for the community to start playing does it.
