The factory P72 (94-95 OBD1 Integra GSR) ECU's have built-in IAB (intake air bypass) control circuitry. This allows the P72 ECU to control IAB operation for optimum engine torque and power output at varying engine rpm. When using the Hondata S300 setup in a P72 ECU, the IAB's can function normally and the IAB operation

For those of you looking for the IAB pin needed for the B18C4 scroll down to the bottom of the page. That all said, here is the OBD1 big mash-up layout: Common OBD1 pinout. This layout is based on EDM and USDM P06, P28 and P30 ECUs for D15B7, D15Z1, D15Z3, D16Z6, D16Z9 and B16A2 engines, but not limited to.

In this article, we show you the full OBD1 pinouts of Honda, GM, and Ford vehicles. You can also download the handy PDF file for free!

2003年3月25日 · Swapping an H22 into an f22-equipped car, you will need to add: The wires listed above AND. . . The pin locations above are in reference to the standard OBD1 Honda Pinout diagram (which is the same for all OBD1 Honda/Acura vehicles: …

2008年3月3日 · This is the parts kits used to Add OBD1 Style (ECU grounds) IAB control to your 11F0 or 1720 Board P05, P06, PR4 or P28 ECU. IABs or Secondary Intake butterfly valves are used on Stock GSR and Stock H22 intake manifolds, please read our write-up in the Tech Center about this and how to install these components to your ECU."

2004年1月12日 · Directly from the solenoid you will need to run the green/white wire to pin A4 on the ECU, which is the VTEC Spool Solenoid Valve Control. Next, connect the orange/blue wire to pin D6, which is the VTEC oil pressure switch input.

2025年2月22日 · From what I've read the IAB pin on the JDM ECU is 17 not 19. My conversion harness has the OBD2 pin A26 going to pin 19 on the OBD1 side of the harness. This was my first concern, but I decided to see if the IAB's would work the way it was wired. So, I hook up the JDM P72, and I immediately get a code 13.

The document provides a detailed pinout for the Magnetti Marelli IAB ECU used in Fiat Palio and Siena 16 valve models, listing various electronic connections and their functions. It includes information on sensors, actuators, and diagnostic connections relevant to the vehicle's engine management system.

2006年6月24日 · The auto ecu's already have everything needed to open up the IAB's. Take out the resistor in R135 and take out D13 if anything is there. Put a jumper from the right side of R135 and connect it to the left side of D13 where the arrow is pointing just like in the picture. A17 is the pin for the IAB's and the ecu is sending the ground signal ...

2004年9月16日 · For the IAB you will need to move A20 to A17. Since you will be using the OBD2 engine harness and an OBD1 GS-R ECU you will need to cut the black wire at the IAB plug and give it a 12V switched source. You can get this from the yel/blk wire at the injectors or the IACV.
