2.2Hdi 180bhp remap vs Diesel Tuning Box

[Doggy]

It's almost irrelevant what's in there. Ultimately, its purpose is to mislead the ecu about the fuel pressure so it will be increased artificially.

It's enirely possible there are more sophisticated devices that may be selective about when and possibly how much to modify the signal, but the only possible way they can increase power is to fool the ecu about how much it 'thinks' it's injecting.

Here's your answer.... http://www.ebay.co.uk/itm/Diesel-Econom ... 19aef94822 They certainly talk a lot of crap. It's clear that there are a couple of resistors in that box. And the "chip" is probably just a series of resistors, rather than a proper IC type chip.

Absolutely, All this is the direction I feared my post would lead and is is missing my original point in that the driving experience such a (potentially basic) box gives is close enough to a good, proper 180bhp remap (giving the benefit of the doubt to the unknown created of the 180 map) to be almost indistinguishable during normal driving.

Anyway as we have gone down this rabbit hole so far we might as well continue the journey

Pulled the board out the box this morning and pictures are below.

Both "chips" have had their markings crudely ground off (which is a shame) implying they are mass market (basic) affairs rather than anything technological.

The set of dip switches appears to control the path through the larger 'chip' potentially corroborating Captain Jack in it being a series of resistors so you can switch up and down the resistance level (it was on 7 out of 8 )

No idea what the smaller 'chip' is doing.

So overall, more simplistic than I hoped, but not as basic as a single resistor inline in the wire.

Seeing as all the big boys are already in this thread and to give you something else to talk about before you blow a resistor How do you guys fair with your insurers?

Didn't really want to open a new thread just for that... Btw nice crude work whoever rubbed those markings out.

[Bailes1992]

Don't think I'm dead against tuning boxes. I think they have their place for quick, cheap and temporary power BUT I think log term a remap is the way to go.

Have you tried them back to back? I bet you'd notice a difference!

[Captain Jack]

Er......

[steve_earwig]

And how would they ever find out? Score one for a remap over a tuning box I reckon

[scotty73]

They were the kinda replies i was hoping for.

That really does look rather basic. Would it be risky to ask what brand of tuning box this was/is?

[Captain Jack]

They certainly make a killing on these boxes. The parts aren't worth more than £10...

as per the link posted earlier, Diesel Express http://www.dieselexpress.co.uk/

From the site:

"Fully Digital with Microprocessor controlled settings, non linear maps..."

erm. ok.

[Captain Jack]

They really shouldn't be allowed to operate. At the very least, they could be honest with their customers and put blow smoke up their arses... It will then be down to the car owners to decide what is best.

[Bailes1992]

Thing is you could buy some conectors (Most connectors on cars are universal) and a 150ohm resisitor from Maplin and make your own!

The microprocessor is more than likely just a series of resistors, when you change the settings it just adds or subtracts the resistors.

Seems very suspicious that they have ground the top of the proccessor off too!

Personally I would rather a box with one resistor in it, or a single variable resisitor because at least you know where you stand!

Maybe I should make a 'tuning cable'. Would probably cost me a fiver a cable and I could chuck them on ebay at £20 a pop!

Anyone take a picture of the plug for the FPS? I can work out exactly how much one of these would probably cost to make.

Looks fairly good on the surface, but only using a gmail address. Would be interested to see how the likes of TDi Tuning & Dragon etc compare as these appear to be more professional & it would be reasonable to expect something of a higher calibre.

However, that doesn't necessarily mean that their products would actually be better. It could just be the exact same components as the Dieselexpress box, but just of a higher quality.

£74.95 13 sold.

anyone want to buy mine?

if you search for 406 tuning box (http://www.ebay.co.uk/sch/i.html?_trksi ... &_from=R40) you will find loads that look identical apart from the sticker. I would suspect some factory in china tuns them out by the bucket load and resellers (like diesel express) put their own sticker on them
