I'm planning on producing more of the CAN interface boards and selling them. I could support M/S52 compressor with pressure switch or S54 compressor with pressure sensor.

Originally posted by R3Z3N View PostI would also purchase for either S52 or S54 compressor, however I would prefer to use the S54 compressor.Originally posted by Staszek View PostYes, if you make this I will purchase! So you are saying you you can use either S54 or S52 compressor?
The pressure switch vs pressure sensor does affect the way the DME compensates for load. It can do a better job if it uses the pressure sensor. It will also regulate the aux fan speed based on pressure and radiator outlet temp.
My latest board prototype with work with the pressure switch or sensor. Compressor doesn't matter. It will also drive a check engine light. I hope to have production-ready batch of them completed in the spring.Last edited by gpeterson; 11-24-2015, 08:37 AM.

Either compressor will work. I wanted to use the S54 compressor because it is variable displacement (should reduce/eliminate cycling) and I got one with my motor.

Any update? I could actually use this now.-Dave

I just noticed your username/location and realized I purchased an item from you in bf.c last week. Funny.

Ha hey Garry! You should see the airbox tomorrow depending on the weather (it's snowing here now).
I'm getting ready to tie up the wiring on my S54 swap. I had the CAN wiring added to my swap adapter harness to make this addition very simple. I'm mainly interested in the CEL function right now, but I may put the AC back in depending on how much track time the car actually sees. I have enough wiring in place to stick this unit inside near the glove box or anywhere else really. If you can make something up that would be awesome!

Did you already get your DME flashed?

Frank Smith (TTFS) has the DME now. That would be awesome if you can throw something together!
Sent from my flux capacitor.-Dave
