My Ride: E46 m3
E46 m3 hpf ECU question

So I'm turboing my M3....myself.
To run the motor I bought a used HPF standalone ECU to run it all....I know a lot about engine & turboing & everything. I rebuilt & did it all myself, isn't my first time eaither. Now when it comes to this computer, I'm lost. It came with the computer & some wire harness & extras. I've done as much research as I can & still haven't found a few things & have a few questions... I was wondering if anyone had a wireing schematic or something of that manner for it to show where everything goes. & do these not use a MAF? I do mechanics not electronics...

I can help u out..... I don't have a wiring diagram but I know it in my brain....


Aem ems and attached bracket. Has two sensors one brass ( boost for external Gauge it has no other use) stainless is the map sensor for the Aem itself. ( Aem is configured by a combination of tps and boost reference map/ table) This needs to connect to vacume rail. Two relays one for,inline fuel pump the is boost referenced to start at 2-5 psi depending on stage of kit in AEM. The other relay is for oil scavenge pump and is set to prime on engien start and shut down and is 13 seconds. There is a harness that plugs into gauges particular importance is the AFR Guage which is used to decode the AEM specific o2 sensor and send that info to Aem ems externally as opposed to internal.

No MAF is used.... On the DME side of the harness there is a AIT sensor connection fits under intake. . Also main harness from Aem running on backside of engine runs to jumper-box. Jumper box In turn plugs In to DME and DME connections plug into jumper-box..

Feel free to email me with questions. acafik@live.com
