Guessing you have a 90 spg.? perfect for the setup. You just really need to take an old LH2.4 ecu, unsolder the connector, and make an adapter to plug the MS into your stock adapter w/ a little cleverness.
You can use the stock relays (power, fuel pump), they are setup up in a similar manner
Use tps from a 90+ 900s w/ LH2.4.2
Get an AIT sensor and bung from a 91+ 9k turbo, the sensor curve is identical to your ECT so reprogram the therm tables w/ the oem temp/voltages out of the Bentley. Have the bung TIG welded onto the IC->TB pipe (if newer type), otherwise just tap a hole into the earlier style. I have some picks of my pipe w/ H20 nozzle bung too, but I haven't setup my ftp program yet. You can use the NTC resistor connector under manifold to attach the AIT sensor (wire 23 on OeM LH connector).
You can use the stock AIC valve, if you replace transistor Q5 w/ a NPN Darlington (TIP-110, 111, 112) and use brian fielding's PWM IAC code. This allows control of the oem aic which is a single pole 100hz pwm valve. He's even edited MT to set it's parameters.
For the injector programming, run injectors off one of the FET's and use single fire mode.
Other than that, all the other sensor will work perfectly.
And if you want to... Edit Eric/Guy's DT code w/ the PWM code. The DT code has the ability to map each fet output indepedently so you could use it to map h2o inj using an Aquamist HSV. You'll have to run a 2nd line out to the engine though, the 91+c900t have a 5th injector line already, too bad. If you setup a diy h2o inj like I have, add some code to trip a transistor on one of the extra output to activate the pump when the 2nd fet output is greater than 0 (w/ the aquamist setup, it isn't necessary given the pump is press activated). Something extra in the DT code is that Eric programmed for a single pole solenoid bc on one of the other outputs. The signal goes to one of the jpr's. I believe it is programmed for 40hz, so some editing needs to be done to lower it to 12hz (for oem saab solenoid, audi valve might be 40hz though) and and an external jumper board is needed. Working on that right now. The boost control is TPS dependent which is kinda nice. W/ mappable h2o inj and bc, you could probably dump the apc system, especially once MJ is released w/ ionic knock detection for timing control.
Fun stuff..
