FooSchnickens:
Thanks for the great looking pics. I have a couple of questions for you:
1. the black hose on top thats connected to a 90* nipple, where it the other end connected to?
2. does the coolant still run through your IAC?
3. Is the OEM ECU still controlling your IAC?
TIA!

The 90* connects to the fuel pressure regulator and the MAP sensor on the piggyback unit

Yes, the IAC is still functional

Yes, the OEM ECU still controls it. The piggyback unit merely translates a MAP signal into a MAF signal the ECU can use. Sorta. I'll be mving to a standalone soon which will still be able to retain the IAC and all the other OEM functions.
