I am running the factory e30 aux electrical fan for the AC and a viscous mechanical fan for the engine.
I have a factory chipped MS54 ECU on my e30 swap. E36 compressor with factory e30 wiring for AC.
The idle bog with AC on drives me nuts and sometimes stalls the car in heavy traffic in hot weather.
If you recommend running various e46 components, i will get them and install them. I have no issue trying to improve/optimize my AC setup.
Please let me know what you recommend and when your components are available.
Thank you.Ian Simon

BTW - the current board design has the following i/o capabilities:
Input
-2x digital 12v for E30 A/C inputs or E36 A/C input (only one used)
-1x digital gnd for E36 A/C input
-1x analog for E46 A/C pressure sensor (not required but useful if running E46 PWM aux fan)
Output
-3x digital, can be used for any combination of lights for check engine/cruise/EML/oil level warning, driving a relay for additional single speed aux fan, or ?
I can customize the firmware depending on your installation. My E36 install is using the E36 A/C inputs & E46 A/C pressure sensor plus outputs for CEL and running a SPAL puller fan (on at 210 degrees, off at 200). I can provide firmware updates via email and they can be applied to the board by connecting via USB.

For anyone interested - I'll also flash your MSS54 for to make it work with your swap. $100, return shipping via USPS Priority Mail is included. I can also do it remotely if you have a vagcom or k/dcan cable. I don't do any tuning, just swap flashing.
Mine is running perfectly in an E36 and the E30 isn't much different. Each flash is customized depending on what equipment you want to keep in place - anything from retaining all emissions components to a fully stripped track car.

That is a steal of a deal.
I'm ready to buy one of your modules whenever they are ready.
Ac signal and cel plus maybe the oil level sensor as well.

Yes I'm talking about the flash.
250 for the module sounds acceptable.
Let me know when it's ready to ship, I'm ready to buy.
Will it come with wiring instructions?
