I've noticed that, more so when running 50/50 SVO...the engine 'fluffs' its way back down to tickover...to the extent that I've sometimes wound it quite a few turns back to eradicate it.

In the absence of a rollin road, it probably wants someone riding shotgun to tweak it for you as you stamp on the loud pedal, cos I'm not convinced that setting it for tickover is necessarily the optimum....just like a decently tuned V8 runs like shite on t/o....

But I find the biggest difference is overtaking, it just GOES!!!!:augie

well see if you can do some adjustment while you're on there.....

 

[makeitfit]

Just done some more "adjusting" tonight :lol:lol:lol:lol:lol
I love it
Took ALL my tools out just to see what it would do:lol:lol
Chuffin' ACE tweeked de screw some more just to see like a test :augie
First roundabout, tailout big time:sly:sly:sly what a larf:clap:clap
Popped down to the other roundabout we have in these parts where it's got that extra grippy stuff on it, HA HA HA HA back end tramping like mad:naughty
BFG are meant to wear well aren't they:augie
Anyway did a few runs and got 0-60 at a tad over 12s:augie
That's on big boots too, anybody know what the std does it in? Just incase I'm 'cause I'm easily pleased

 

[makeitfit]

Ha , just found the technical data list.
Acceleration 0-62mph secs 15.7 :augie
That's for a new one that works I guess, so 60 in 12(ish) secs:thumbs on my old bus seems brill.
Well chuffed, go buy one:clap

Zippy its a titchy little black box hidden behind the dashboard....work it out for yourself :sly:augie

 

[zippy656]

i see your point..

How much smoke are you getting off / on boost with your TUNIT box?

I'd love to know how much turbo boost you are managing to sustain over the rev range with the box turned to various settings.

I get no smoke on mine Tim - and what you talk about is the challenge here.....the unit is already around £275 even for a refurb (I think its closer to £400 new) so you'd have to add quite a bit of dyno time on to that to fine tune it....especially if you were to keep adding mods. The Tunit guys were clear that you can very easily get additional benefit from, say, a fatter exhaust, just by retuning....but the problem is, without using a dyno the default tuning method is very basic.

The unit has screw adjustment with about 30 turns lock to lock....to set it up you run the engine and turn the screw clockwise until the engine rpm increases and then eventually starts to 'hunt'. At that point you turn it back 2.5 turns approx and that allegedly is max power point. Further anti-clockwise adjustment is allegedly into economy territory.

They do offer dyno setup via their dealer network but (i) that costs money and (ii) would need doing again every time you make a mod of some kind - but is the tickover adjustment routine adequate? I suspect some in-flight adjustment, especially using the boost gauges etc.. that you always recommend, would be much more beneficial...

But in all seriousness, the lads at Tunit are extremely helpful as Pete will attest.....just tell them you've seen several of them talked about on the site here and I'm sure they'll be keen to chat - just don't expect them to tell you whats in it! And someone with your knowledge may well get a new perspective...?! They have a website with contact numbers for their Lancaster HO. http://tunit.co.uk/

 

[makeitfit]

I've set mine nearer the power end of the screw spectrum:sly
It smokes a lot on start up as you'd expect then settles down to a fog!
I've got side exit exhaust so I can see some smoke at dusk but it's more fun watching the speedo:naughty
I haven't got a clue what the boost is doing as I've no gauges:augie
Fitting the gas tank tomorrow I hope so will do the rolling road after that.
Probably need a new clutch soon too:doh

 

[Terranosaurus]

Is it the TUNIT II that fits ours?

Surely the boost will be the same as theres no boost control on the ECU anyway. The TUNIT box is just adding more fuel and probably at a different time too.

 

[makeitfit]

Yep Tunit II + 4 I think is the full title:thumbs
However I've since found that if you have one from another car say, you can part ex it with them against the one you want:sly
I could have had one for 50 squid off the bay but wrong motor:doh So if you're interested ask them what the deal is first, then spy fleabay

 

[makeitfit]

As a matter of interest I did a miles per gallon check before going onto the tunit.
It's awfull at 24.8 mpg over two tank fulls brim to brim.:doh
That's all local country road stuff and not tootling either. I overtake anything I can on the way anywhere, and the trucks always full of tools.:augie
So I'll report back in the next hundred miles or so how things are in power land mpg:sly
