The wiki page on pgmfi is not working and I can't find anywhere archived on here how to do it.

Can anyone shed some light on how I can modify the p28 ecu to run the secondaries on my h22? I don't want to zip tie them open or run additional wires either.

 

shoot me a PM.

 

sent. why not post it in here lol

 

cause its one of john's super secret tuning abilities.

haha, na it is just easier to discuss over a PM.

 

The procedure to add IABs is different depending on how they are wired. One IAB wire will always run to the ECU, the other will run to either +12v or gnd. Choose the procedure to match how your car is wired! This is very important!

USDM ODB1 B18C: ( ECU sends ground, IAB wired to +12v )

IAB conversion... (this is for Manual cars only, but an AUTO USDM ECU converted to manual will have all the parts you need present)

Remove: R135...11F0/1720 autos only R150...1980/LS only

Add:

Q17(A143)...already present on USDM auto 11F0/1720 (A5x, L5x, etc). Not present on EDM auto 11F0/1720 (G5x, etc).
Q34(D1780 or C3225?)... already present on USDM auto 11F0/1720 (A5x, L5x, etc). Not present on EDM auto 11F0/1720 (G5x, etc). may use PCS trans: Q31(D1780)
jumper from right hole of R135(trans side) to D13(arrow side)

Jumper wire for OBD1 IAB control:

your welcome.

 

Exactly. The OBD2 version is a bit more tricky. It is a easier to just rewire the car and run the car off the OBD1 version.

 

its not that bad you just gotta know what obd the iab is.
