Maxchip ECU Tuning Box

Got a link ? . See it's alot harder to run an interceptor on a petrol car , on a diesel you can get away with it cause all you are modifying is the injection duration and perhaps inj timing. On the petrol unless you can modify boost the gains won't be much at all . In fact you really have to do ignition timing, fueling and boost so it's alot more complex especially on a modern engine with so many failsafes. I could go into more detail . Anyway they might have sorted something out just make sure you log it to make sure things stay happy

I'd be interested to see how you go with it; I don't see how that kind of unit can modify ignition timing, whilst modifying injector duration times and at the same time modifying the real boost but also fooling the ECU into thinking it is running a near-stock level of boost at the same time. There's alot involved in a proper piggyback setup!

Yeah, I frankly don't want to be the first to try this. I'm at least going to wait until more is known. I think the 1.2 tsi box is a new development. I'm going to wait.

I did a road trip to Sydney on the weekend to see Neil Diamond actually. Four adults and baggage up the Hume, and I was really impressed with how it pulled. I just put on the cruise and it only dropped below my setting on a couple of occasions and there are some reasonably steep hills in both directions. So I'm in no rush to soup it up.

i dont see how this would work on a petrol? what's in the box? hopefully it's not just potentiometers / resistors etc...

one thing that strikes me as odd, with this product, is there are plenty of tuning-box companies for diesels, and they're damn good at what they do - ptronic, diesel power ca, chip express, dtuk, etc etc... these guys are the kings of piggyback tuning boxes in the diesel world... why arent they making a mint with petrol cars, too, given their expertise? or is intercepting the fuel signal and causing the computer to request more petrol a slippery slope?

good luck with whatever your decision may be. i love the polo 1.2 tsi - took one for a test drive, i was really, really impressed. if it were my car, i'd have greater peace of mind going with a proper remap by a reputable tuner who has tuned your particular car too many times to count, and reliably.

not to "push" the product, as i dont have a DNA tune myself (im with Viezu/ChippedUK), but i've seen at least 3 cars with DNA tunes on them. all owners extremely happy, all cars pull HARD post-tune, all cars very daily driveable post-tune (read: damn smooth), etc etc...

the extra $430 premium that John is charging in the DNA tsi promo deal is really a tiny price to pay for what you're getting. i know you're concerned about warranty, and i was extremely concerned before i got tuned too, but if you go with a reputable remapping service.... pffft. nothing's going to happen to void your warranty - it's in the tuner's best interests to work within acceptable parameters, whilst still putting a big smile on your dial.

Guday everyone from UK,
My 1st Post on here, I have one of these on my Allroad 2.5 TDI 180, takes it to 220 BHP but I bought it for the fuel it saves...
adverage of 19mpg to 30+mpg...
They do work well on the diesels, as for petrol....not sure. I went for one as did not want a perminant re-map and they can be transfered to another car.
