Opinion on diesel tuning boxes

[chris_r]

Hi all,

I'm aware that a few people on here have or had diesel Astras with tuning boxes fitted. I have a turbo diesel Hyundai iLoad van (I work as a contractor for Aussie Post) that's now out of warranty and was thinking of fitting one of these boxes to it. Only problem I'm having is choosing which one.

I see tuning boxes go for anywhere from $150 to over $1200, but I'm curious as to whether the more expensive one is really $1000 better than the cheapest ones. In my case I spent about $33k on purchasing the van new, so I wouldn't be fussed spending money on a decent unit, but I don't want to be wasting money I don't need to on a unit that may perform just slightly better.

So can anyone shed some light on this little conundrum?

Some just act us resistors, others will actually take in the boost and throttle values to input fuel by raising the commonrail pressure.
I had both the greenbox and the crdt from dieseltuninguk on my astra, never had any issue at all with either and both worked extremely well. Both were also plug and play so could be installed or removed in a matter of seconds.
I'd check out if they have one for your van, it's a brand I trust.
DPchip also do some good Aussie based ones, but are more conservative on the power and torque than the DTUK ones

Thanks, I was looking at the DTUK setup. Apparently, the iLoad/iMax vans (in the UK it's called the i800) require a different type of box, as the usual methods won't work on these engines. For less than $600 landed, it sounds like a reasonable deal. Especially when I can apparently go from 125kW/392Nm to about 155kW/470Nm.

It's become an interesting topic for me too recently Chris, as I'm 'possibly' looking at a TD sometime next year as daily driver update, alot of newer and upcoming TD's and TTD oilers are finally starting to look desirable IMO

What I've found is that most brands give or advertise a straight 25% increase over stock power and torque figures (some of which I find hard to believe without a dyno verification) and some have an adjustment to go either up or down, they also claim/advertise better economy with 'normal' driving...

Maybe some of the guys on here (Ain and others) who've had oilers can shed some light as to whether those numbers are actually achieved or not ??

Hi mate,

Look up the i800 on www.superchips.co.uk

I've also got a diesel iLoad, we flashed it in house here with superchips, and it made 165hp at the wheels, or basically what it started with at the fly:





And the thing is now suitably a rocket ship, and tows the rally car like it's not even there... Under a $1k.

Anyone in Brisbane we can do the Superchips/Bluefin flashing, but not sure who does it in Adelaide. I've also just Superchips flashed my diesel Forester, with also similarly incredible gains.

Computer can also be reverted back to standard if need be...

Any questions at all just let me know, but some of the results we get from the VAG diesels (Polo, Golf, A3, Touareg etc.) are quite incredible!

Cheers,
Greg

Hey Greg, are you able to get any numbers from or have you guys done any of the current 'blue efficiency' MB oilers at all ?? specifically the 250 CDI 2.1ltr TTD engine, some of the numbers I've seen from tuning boxes on those do seem a little incredible or hard to believe...

LOL he does seem to be everywhere, but it's all good

The numbers are definitely achievable, at least with the Astra. Stock ~ 90fwkw, greenbox ~ 118fwkw, crd-t ~ 125-130fwkw. All with little or no sacrifice to economy. on long hauls they actually improve the economy.

Checkout the Superchips website (the UK one, not the Australia one as it's not updated as often) and if it's got it listed, it will have the claimed hp and torque increase. Having personally done my diesel Forester and diesel iLoad (both modern common rails) I can definitely vouche for Superchip's figuires being damned close to reality... In fact the iLoad exceeded the expectation...

Having seen what they screw out out of the VAG group of diesels, nothing would surprise me, and at the end of the day they all run the same management systems, so the results are all very similar. The iLoad runs the Bosch common rail computer (same as most of the Euro's) and the Forester is a Denso unit. There's not really any other systems used by modern Diesels... and having had two modern diesels (both still owned) I'm a massive fan of them!!!
