When I had the 3.27 gears and the EL Ghia Tickford ECU, the auto maps worked ok. They were a little out of synch at times, only really noticeable to the really picky when slowing down to a stop. |
My repair manual indicates the same upshift points for the standard EB 3.27 and XR6 3.45, and it's not overly clear but seemingly different kickdown points (95LE versus 91LE XR6). I don't have information for the EL. Is that what you mean?
Could a tickford ecu controlling a non-tickford motor allow it to over-rev?
Another point, i figure the ecu relies on the speedo drive gear to know the vehicle speed. So if the drive gear isn't giving the correct speed due to altered wheels and/or axle ratio, this will have an effect on the shift points. The effect may be positive or negative, depending partly on the drivers preference.(?)

In that case, what do you see as the differences if any between the fairmont ghia and xr6 ecu's? It seems they have the same motor and diff ratio.
To summarise:
EL fairmont ghia tickford 3.45
EL XR6 tickford 3.45
EL fairmont std4.0L 3.23
EL GLi std4.0L 3.08 |
