This has probably been asked 10 times before but i have searched and cant find anything.

BBtuning do this:

A timing sensor with advanced ignition. Is this a totally pointless mod that will end up causing problems in other areas of the car? Also is this really in essence what one of the things a "Chip" does anyway?

6 degrees seems a heck of a lot of advance to me. (coming from other engines I have experienced anyway).

It doesnt work.

[Scougar]

That's a sweeping statement

1) The product doesn't advance at all (Then trading standards need to be involved)
2) Product does advance ignition but has no noticeable effect.

Which of the above?

Advancing the ignition on any previous engine I have used definately increases the response when you use the dizzy, but this I don't currently know how it works with the F7P/R's.

The ECU controls the ignition advance on the F7P / F7R

The theory is your shifting the refernce point in relation to the pattern on the fly...so u can swing the timing. However, the large radius of the fly means that it would take a large ammount of movement to give a small angular increase/decrease.

Yeah I thought it would be a waste of money, but I came across it on their site as thought I would ask

So basically its lying to the ECU about the position of the crank?

Ive got one on mine and seemed to make a lot of difference .. saying that though my old one might of been fooked ! also run 99 ron and a mapped chip if that makes any difference
