microsquirt ford A4LD OD control

Post by techdog1 »

I have several questions about the Microsquirt. Can the Microsquirt be set up to control the TCC and OD solenoids on a ford A4LD transmission? I will be using it for fuel and ignition on a 2.3 turbo. Can I use the outputs on pins 16 ALED and 17 WLED spare relay outputs to do this? Also can the outputs be programmed to provide the output based on TPS and speed, or MAP and speed Inputs? How do I set up the conditions to allow the output control?
Thanks

The main problem with this is that it's very difficult to get a speed signal into a MicroSquirt (unless, of course, you're using its transmission control code version).

MegaSquirt?

As far as I known MegaSquirt can be used with the 6 Ford injectors in Batch Fire mode, 3 injectors on each ground and if you get the newer units you can also use it with stock waste spark coil pack, 3 grounds as well

Might need a flyback board kit for the low impedance Ford injectors, if you have an old Megasquirt unit
(From MegaSquirt: you do NOT need this if you are using a MegaSquirt equipped with the PCBv3.0 or later, this is only for PCBv2.2 users running low impedance injectors!)

The A4LD did have torque lockup and 1987 and up, OD shifting via solenoid done via stock PCM(computer)
You can use manual ground switches for these
