With Ryan being away we have had to do a bit of research and spend some time on it ourselves.
What we have found out is this box very advanced, there are only three manufactures in the world making 8 speed boxes.
The AA80E has been used in a few different Lexus models and also in a Cadillac in the USA.
We are now very confident this box will hold some big power, 700ftlbs (900hp) plus should be no problem at all in stock form.
It works very differently to a conventional Auto Gearbox which is why we have had issues controlling it correctly on the Syvecs ECU.
We have improved it a lot with the time we have spent so far and its starting to drive very nice.
The performance side is amazing and the gear changes up and down are lightening fast, it really doesn’t feel like an auto with a TC.
We are working to try and add some settings to the Syvecs gearbox strategy so we have more control.
The other option which Ryan will be working on soon is to use the stock Lexus gearbox ECU to control the box.
This will give us the silky smooth control that we need but still ability to adjust settings. This is the same way the R35 is done.
With the work so far we really like the box and once completed will be an awesome conversion for an auto supra.
