I am ssure Marty wont mind!

Well in Order to Fully test and debug the AA80E Controller, AA80E transmission, and also control functions (paddle shift etc etc) we are building a Transmission test Rig. We started today on the Bare bones of the Frame Work.

And the plan..
We will be using a 3HP 2800 3 Phase motor which will be motor than plenty to spin the aa80e with no actually load…ie. the rear diff and wheels and car weight.
The 3phase motor will be controlled using a single phase to 3 phase digital inverter unit. This will give us full control of the motor speed and braking. In theory at 200hz we should see around 5000rpm at the motor, though 3500rpm is all we need for most testing.
Transcooler will be mounted on the test rig, and from the bench we will have our paddle controllers, selector mechanism, load and tps STIMulator and PC to monitor and edit Data (Megashift) from the Trans controller.
This will save a lot of development time and help iron out problems a lot faster than trying to do whilst in car.
so the basic idea is..

Well TFT Display is almost complete and was test fitted to the car today. We have several data layout screens for Aux and AA80E information. The next part is interfacing data stream to our custom controller ECU which has be STIMulated so far.

We have a few other features now incorporated in the TFT and Control system.
1. G – METER is now functional using precision x,y Acell board

2. Full suspension control – Using our own designed 4 axis stepper contoller and high precision motors with rotary encoders we can now control damper settings on most adjustable coilovers with modifications to adjustment dial hardware and motor mounting. Data can also be used from ecu such as driving mode to determine preset values for damper rating. We will have a full post on this when we have choosen which suspension to run with.
3. Rear Camera – Using power interupt and AV decoder board we now have a functional rear night vision camera display on the TFT when enabled. This basically is initiated when reverse is selected causing AV signal from rear mounted camera to be fed to a seperate encorder board and bused to the TFT controller board. Nothing new but may aswell have it seeing we can
The interesting stuff will start to happen after the transmission test bench has been built..

Well getting a few things sorted. Transmission test bench almost complete, finishing off the rear bumper, and have also started the exhaust system…so heres a few sneak peaks..
