I believe this is for the Petrol vehicle, so no use for your diesel 300!

Hello Alastair,
No good for diesel... How about Veg?

Really, I just lost four pounds then...

just got a reply from the seller:

If you have the sensor then it can be modified
I have one on a 2001 vitara diesel with a peugot engine in

Perhaps it does something...

I got it, its a simple resistor that attach to the temperature sensor plug instead of the sensor. I did notice something but I wouldn't say much at all...
Its a 17 pence resistor, I'll get the value later and post it if anyone want to try.

Finally got the resistance value, sorry for the delay. If anyone want to try, Maplin ( like radioschack) told me its a 4.7 K ohms resistor.

Veggie oil or diesel won't change what sensors you car does and does not have.

AFAIK neither of my cars even have IATs. All you're doing is making the PCM think that it is seeing the coldest air so it will run more fuel. If you don't have more air flow in and out, what is extra fuel going to do for you? Make you mpg take a dump.

If you can find an IAT on your car, you can give it a shot and get back to us, as a resistor can't be more than a couple of pence. But don't expect any changes.

I have it in the car since I post the topic. I think it does something but minimalistic and certainly not the 30 HP gain, the best would be to test it on dyno. I have slightly blocked the air for the booster sensor as well, those 2 might do a bit of improvement, but again, only a dyno would tell.
