No idea, fixing the misfire first.

Oh yeeee,
How does she sound??

Well damn, Higgins muffler did a great job! He fixed my O2 sensor clearance issue, 2 02 bungs for wideband in both banks, and post cat bungs, though I would need to lengthen VERY much, but that is perfectly fine as they are just used to check cat health, not for any engine parameters while running.

Correct the file is for gen 1 board with coolant and pressure sensor. 2nd digital out is for second trigger at temps stated, using a relay. Though for ease of tuning Derale makes an adjustable pwm fan module, that way you are not relying on files or or switches for a puller, and you get something easier on your wiring

So I said to myself, why finish later when this software trial ends tonight at midnight. After this it will cost me at least $7 for Visio, or $109 for a year of SmartDraw. So I whipped this up and added what is needed for a full MSS54/HP A/C and Aux Fan experience for the Gen 1 CAN board.

This one represents the program file you sent me correct?

[R3Z3N]

Hope to maybe get a pic if I can drop in on the exhaust shop. He is V-Banding the system, 2 Cats for CA visual and sniffer, post O2 bungs (even though it is coded out) and 2 bungs pre-cat for my Wideband LC-2 and George Graves Narrow/Wideband in visual in car. Going dual 3.5" all the way back. Not sure on muffler. No resonator for now on either bank.

Going to pass smog first and then add a remote electric exhaust cutout for fun.

You're a genius this build is insane.

Verified AC Pressure sensor connector is P/N: 61132359998
Real-OEM is F*ing wrong.

Just read this from start to finish ... WOW - IMPRESSED.

If the M50 in my '88 M3 ever gives out I think I would try this.

Again - every so kewl.

For the pressure sensor check out what I did on the last page of my thread, if you want you could send me your sensor and I can modify it. Granted it hasnt been tested... But also, there are adapters, 1/8npt to whatever the pressure sensor is. I found one that came with my VDO gauges, but the adapter wouldn't incorporate the E46 O-ring which may not be a concern if thread sealant is used.

Notes for later when the car is back, will be input into OP once verified and pics taken.

Items needed to control AUX fan with ECU such that Aux fan will be triggered for engine temp, engine speed and AC Load/Request:

PWM fan Module from E46.
•P/N: 64546988914
Not sold separately from fan, but can be found parted out elsewhere such as ebay. Choose your 2 and 3 pole connectors. I found a stock E46 harness clipped to length on ebay.

A/C Pressure Sensor & Connector
• P/N: 64536909257 Sensor
• P/N: 61132359998 Connector
Connects to Gary's CAN controller. Easiest? to have stock E30 temp sensor cut and welded closed, then tapped for the E46 versions threads.

Lower Rad Temp Sensor and Temp Sensor wiring connector (need connector part/pins)
•P/N: 13621433076
Needs to be in lower rad outlet IE via 38mm? (or 36mm, not sure) rad hose joiner with thread for temp sensor such as this from Amazon This adapter needs to be tapped for M12x1.5


Wiring schematic to come for Gary's Can controller, X60004, and chassis side. I wont be able to install this for at least several months though for pics.

[masterofnone]

You just read my mind from across the world, wild...

Im in China at the moment, but Im very interested about your plug and wiring information. Im looking for the coolant temp sensor plug in the lower rad hose too, if you know where to source that. I think I got it figured out but I feel you may be more of an electrical wizard than I aha

[R3Z3N]

Decided once I get the car back, I will add the PWM fan module so that there is less shock to the wiring/electronics with the huge 16" Spal 30102048 fan. I'll start documenting what is needed, and make another wiring chart for that for the Can controller and DME so that it's visual.

Hopefully I bought the right connector for the AC Pressure sensor, real OEM is piss poor for finding connectors/pins imo as I wish they were cross referenced as to what is compatible. Otherwise off to the junkyard or buying the harness and snipping it for 1 plug.

Nice! Looking forward to this!
