Uncle said:Hi all,
I've got an Ford AU3 Fairmont that has aftermarket rims/tyres.
This throws the speedo out by about 10%.
I am trying to sort out whether a Jaycar speed corrector
(http://tinyurl.com/dblvbw) will sort out the speedo error without
incurring other issues.
Other issues may be shift points for the auto transmission and/or
problems with cruise control.
I've hunted around the net looking for answers and came across a post
where someone suggests that to control shift points it may require TWO
First corrector to drop the signal from the auto transmission to the
speedo and the second corrector to increase the signal from the speedo
to the ecu.
Can any of you electronic boffins shed some light on this for me.
I'm competent to assemble and install the kit but when it come to
understanding electronics I'm lost.
Thanks for reading.
What about putting the correct size tyres on?
