TDi chips

dont touch them, well its up to you if you do, most of them are a resisitor in a box, which basically fools the ecu into thinking the engine is cold and making it deliver more fuel iirc thus some supposingly extra power gain, i know what you said, but save your money, there are some cracking remap deals around

you could do that for a couple of pence by buying a small resistor and putting it across the correct wires. But as said it no good for engine, remaps can be quiet cheap and if you get a proper one can give around 50bhp with a good amount of torque as well.

The ones that go to the fuel pump simply adjust the reading from the fuel temperature sensor (which is sited inside the fuel pump) and the ecu thinks the fuel is hotter than it really is. As a result, more fuel is injected to compensate for the hot fuel (which is less less dense) and the engine is simply overfuelled.

If you look at the more complex ones in the pics you posted, all of them are literally "straight through" except for one wire which is interrupted to modify a single sensor reading.

as you have a non PD i would get an upsolute map, he travels to you and is a very good price. Ive heard nothing but good things with his work and the non PDs.

my mate got one of the ebay jobbies and gained 30bhp and mae 311ft lb torque proven on rollers on his 130 ibiza

The Picture in the top is what I have on my PD100 Ibiza 2005, I bought one of these because my car has warrenty therefore I cannot remap as it will void it.

This chip has definatly made it quicker and torquey but this thread has really put me off, what should I do, leave it on or take it off?

your call buddy, only you can make the choice, we can provide all the facts and opinions, have a search back through for tuning box in the tdi section for loads more. after reading it all make your choice.

Is the tuning box totally different or something?

but as I said above, its a ten year old car not worth spending £300+ on map for it, otherwise I would run it down to superchips, they arn't that far from me and I have used them in the past will good results.

I suspect an Upsolute map will be comfortably below £300.

Personally I'd go Upsolute all the way, they've got loads of experience especially with the older non-PD VAG TDIs.

Superchips on the other hand have never been held in particularly high regard on here or other forums for the TDI remaps. Whether that's based on any sound reasoning I don't know, but if I had the choice I'd be going with the company that has the good reputation for VAG TDI remaps.

nope, people may refer to them as chips or tuning boxes, both the same essentially.

So the chip that I have which is shown in the top picture is a tuning box???

yes

Thanks mate
