You're likely to gain more HP from the seeds :thumbsup:

Can't even spell Citroen correctly!!

Wow!! A 16 pin Dual in line chip mounted on Veroboard with only two wires connecting it!
Obviously a state of the art product. I wonder if Trading Standards have shown any interest?

Hi all,
Perhaps I am going to put a spanner in the works!

It may work!

The device would appear to be connected in series with the MAF (Mass Air Flow) sensor. This sensor is normally of the 'hot wire' type. This works by applying a voltage across a length of platinum wire which is in the intake air flow. The wire gets heated by the current passing through it and as such it will have (relatively) a high resistance. As air flow enters the engine via the sensor assembly the platinum wire cools down and its resistance increases accordingly. Using these results the ECU can determine that the engine is working hard or less hard and control the amount of fuel into the injectors accordingly.

Now, this device looks a little cunning. Most people assume that if they see a 16 pin package as in the photographs of the device. This DIL pack can in fact be a pack of resistors thus giving the wrong impression that it is some sort of electronic wizardry.

As the engine is required to produce more power so the air mass flow increases and the resistance of the sensor also increases. By putting additional resistance in line with the hot wire sensor the ECU can be fooled into thinking that it needs to provide more fuel to the injectors which will in all probability provide more available power from the engine. The way the ECU controls things should mean that a lower throttle setting is required for the same power output leaving the extra horse power to be available at higher throttle openings. This would appear to be how a large increase in power and a marginal improvement in fuel economy can be achieved.

Now, I am looking forward to comments on my theory and also has anybody tried it yet?

By the way, before retirement I was employed as a Professional Electronic Engineer.

Google 'bore wash' and then decide if you'd like your engine to over fuel for a little more power.

Hi Jim! How're you doing? Long time no see! How's the 'boss'? I hope you're both OK. :thumbsup:

I agree with what you say but the seller's ad states that it's not just a 1p resistor....I suppose it could be a 50p resistor network in a DIL format in which case a 1p resistor of the correct value might work just as well (or not).
I think the seller is relying on people seeing a 'chip' and thus assuming it's a hi-tech piece of kit.

I think Jim's answer is the best reply I have seen to any post ever on the Forum!
I don't care if it's correct or not?
It's brilliant. :woop:
