makes my life easier....was looking at having to pull the ECU's apart and figuring out where I needed to put jumpers across.
thanks for the headsup the other week about it:)..
will it graft directly into the plug behind the selector?.
or will it be another box to hang next to the ECU?
Works well so it does. Nifty.
Anyone know the ratios of an auto Mr2 box?
Can we have more than 4 gears please....:pray:

Mmmmmm tempting.
The unit will hang next to the ecu.
Not sure about the ratios of the mr2 autobox
8 speed Auto V6.
lol only on TB.
I think the 3SFE Auto box has the following ratios :
1st : 3.643
2nd : 2.008
3rd : 1.296
4th : 0.892
Rev : 2.977
I would assume it would be the same for the 3SGE auto?
Was there a 3SGE Auto? I thought they were all 3SFE.
We need Johnny to plug these figures into his machine for us now.
Assumed the same weight as a turbo box for this...
