Diesel Tuning Box On 1.4 Yaris?

[PG1]

Has anyone tried fitting a Diesel Tuning box onto a 1.4D Yaris?

I'd be interested in finding out peoples opinions of whether they are as good as they claim.

I've been looking at the units from www.chipexpress.com.

£400 seems a bit steep for the unit, I guess you need to be doing a reasonably amount of mileage in order for fuel savings to offset the rise in insurance?

And for performance, I just Part Ex-d a 51 T-Sport for a 08 Yaris 1.4D SR. Would a box give my SR the performance any where near the T-Sport?

I presume that plate glass Toyota dealerships would take a dim view of such devices?

Thanks

I have just removed one from a 2003 Yaris.

Yes they give more power, yes fuel consumption is no worse... BUT - when cold the engine - normally quiet - rattles like mad under any acceleration. This was a simple box supplied - by a Toyota dealer.. They still supply more sophisticated ones...

mine is for sale if anyone wants it.,.£30.

I think a remap would be the best option but I still have 1 years warranty on the vehicle. The cheaper Tuning boxes are fine but are not particularly intelligent other than fooling the ECU to push more fuel in at lower revs. The ChipExpress box looks a good contender as it is a fully digital system that has been specifically mapped for a particular engine. It also has the best performance and economy figures of all the systems I've looked at.

Has anyone got any other recommendations?

remap wold be better, all them boxes do is fool the pump into thinking ther isnt enough pressurein the rail and it works harder, in the long run the pump will give up, im getting my yaris remapped on the 3rd october, il keep u posted what power ect i get

Do you still have that running box for your Yaris? What was the brand? Was it for diesel or petrol?

Thanks

Sorry for resurrecting a super old thread - but I guess that's better than making a new one? 

Does anyone have any experience with the eBay chepo tuning boxes for D4D Yaris?

This is the one I'm looking for. The link takes to eBay in case someone wonders what I've linked 🙂 Didn't want to link the long direct eBay link.

TIA as always.

The vast majority of them are usually just a load of badly soldered resistors in a fancy box. Some of them actually do a piggy-back ECU remap (One of the people on this forum worked for a Toyota dealer who used to sell them as an accessory back in the day!), but I suspect those are practically non-existent for older cars.

Unless you have a really strong reason to do this, I'd not bother and put the money to something more useful - Most likely it'd just set off a load of engine codes when you push the engine.
