Ohhh sorry now I know what you mean!

So if it's IAT base X multi X multi2....in my tune nothing reduces timing at all until temps of 85 deg Celsius ECT when multi2 goes from 0 to 1.

Then it...

Thanks - the spark tables are basically modified copies of the HSV table...basically figured they put a lot of research into those so they should be pretty good!

I'll try smoothing spark out a...

Hi guys does anyone have any tips or links on how to use the IAT tables?
I have been searching but can't really find much info on them....ie. what do the multi and multi2 tables do / how do they...

Nah its a 2000 model so that lean cruise is disabled.....but I hope to patch it with pchacking if I can work it out!

Yeah I need to work on them more but I'm just confused as to where the final...

Mine unfortunately doesn't have the lean cruise tab....but it's something I would like to try and add.

Here's my latest tune and log....have lots more advance now (based on 2000 hsv) and leaned...

Oh I think I've worked it out....the secondary table only opened bc I had it saved in favourites....but if I got to the airflow > general then under Main VE there is only the Primary table showing...

Ok Guys, I have successfully installed the SD O/s upgrade!

One thing I'm a little confused with - the secondary VE table looks the same....does the upgrade mean the primary VE is now used again?...

Oh thanks so much that?s the info I needed! Will def upgrade os then!

I had set msg fail frequency & error codes but not dfco - what does that do?

I will upgrade the os tomorrow and see what...

My previous reply doesn?t seem to have worked. I threw the maf in the bin once I tried mafless -
It was night & day difference!
And I?ve been able to add so much more mid range timing without...

Wow thanks for so much helpful info!

That is an interesting proposition to run open loop....I guess I haven't had enough confidence in my VE tuning ability but if I had a wideband I probably...

Hi guys,

Been doing some reading on the forums and basically think I'll just go mafless now considering I have to do VE table that way anyway.
Only thing is I have the early reduced secondary...

Oh I didn?t know the maf needs to be failed to adjust ve?..that could be why I?ve had trouble getting consistent stft & ltft. Looks like I?ll back off some idle timing, fail maf & do some logging...

The hsv tunes have less idle timing so I?ll try matching those to see what difference they make.
They have way more timing in the main spark tables though - where I?m also throwing codes every time...

Oh gees I keep darn confusing the map for cylinder airmass! ahhhh I've done it again, now it makes sense the timing figure is correct. Thanks for that!
I need a post it note on my laptop the spark...

Sorry I wasn't really expecting people to be reviewing those...figured I'd be more likely to have some tips on where to look than uploading tunes and logs but hopefully i'm wrong then!

Here's my...

Hi guys,

I keep receiving knock sensor errors and when I review my log some seem to be occurring at idle.....I'm reviewing one segment which shows idle 611rpm, map 47, speed & tps 0 but spark is...

Hi guys just wondering is there an official product support query line?

Just have questions about hptuner and o/s upgrades etc but I can't find answers in the forums and I don't think enough...

Hi guys in addition to my LC / os questions I was just reading about stft?s and open loop?I had assumed that because the log shows them operating they would be?.and they seem to indicate lean...

Oh the Vx tune is just from the repository - I only own the Wh. Everything I read suggested the os changed from 2000 to 2002 but maybe the lean fuel just wasn?t programmed in on the wh as it doesn?t...

I worked it out!

The VX tune has way more advance and lean cruise mode....but different o/s.....so wondering how I can use that feature?

THanks again!!

I'll upload them just need to see how to....my tune is a 00 old o/s whereas the vx is the new o/s - same p01 pcm though.

Thanks I did try 98 - I could always try and chase down some octane boost and try that.

Car sure felt better with more timing!

Does anyone know how to approach the o/s & lean cruise?

I...

Hi guys,

Im a newbie trying to piece this all together for my early ls1 in a wh statesman.

I've been tinkering with my tune compared to a few hsv tunes which have way more timing just about...

Thanks I have downloaded a few tunes from the repository already but not an auto 285kw ls1......was hoping I can find one to use as a good starting point....

Hi guys,

Well I took the plunge and ordered a MPVI3!

I have a WH Statesman LS1 and looking to mafless tune it but after a starting point as I've never done it before.....everyone seems to say...
