hey kdog
im still tryin to get an abs ecu to try and solve this changing gears properly
to the rest i have wired up a crown 1uz with auto ecu
the auto ecu uses the abs sensor as the speed signal for when to change gears this signal goes thru the abs ecu then to auto ecu
hopefully soon ill do some tests to see in and out signals
i have an electronic signal that goes to speedo
drives speedo then it goes to autro ecuu to use this signal to change gears
dont know if its just mine but i found this
if the speed signal to ecu is too fast the ecu will retard timing when kickin down and its very noticably
if the speed signal is too slow when changing gears at full throttle
it will hit redline
someitmes it will stay at redline and not change till u back off slightly
so just as a warning
to run the auto properly u might need to run the abs computer too
this is just my findings on my vehicle
as i have not wired up an auto b4
mine is a guinea pig
i hope to do more tests on a front cut soon
but at the moment my auto is bout 90% right
goes hard but sometimes changes are funny
its hard to get speedom,eter readfing accurate and get accurate signal to ecu at same time
unless u run the crown speedo sensor and crown speedometer
