4afe ECU wiring help needed

[chali]

Is ac amplifier box different thing tahn ac control unit which is mounted in dash above the blower black ecu type- my car have such box
i just connected check light and shorted te1 n e1 light was blinking fast at same interval-- which means no error of sensors but i need to get fc and ac right- plus whr to power rpm from

FC Will Power Up Your Relay On Crank....So Wire Your Relay WIth FC ....!

@atta1111 Babajee There's No IGN- Pin On ECU....What You Suggest Now???

[SER_GTR]

@xulfiqar....kindly listen to baba jee...he's going to teach us some magical stuff

[chali]

kindly teCH ME LOL

Hook It As TOLD...!

Ser gtr -bro how fuel pump relay is installed and where is its location
1. i connected batt to the battery directly with 10a fuse
other two r connected with ignition switch ( while book says they need to connected with efi relay ) where is efi relay located also

[Xulfiqar]

Uncle ji please ask him not to connect the rpm at IGF pin instead . he has to connect it on the distributor wire which is originally IGN- pin .got it janab

The signal feedback of IGF is the exact same as the coil negative which is controlled by the ignitor, original wiring setup has that thin black wire going to the diag box in the engine room and also to the tach meter. If for some reason that wire is damaged or broken one can use the IGF signal on single coil setup.

This Is A SWAP SO Don't Ask Where Its Located..........They Won't Have Installed It Or Maybe Installed Just Beside ECU...Check For It Or Trace If They Have

Original LOCATION Of EFi Relay Is IN Main Fuse And Relay Box Under Engine Room(Beside Battery) And Fuel Pump Relay Is Somewhere Close To ECU(Behind Centre Console) ....!!

The FC Pin Will Power Up One Point Of Relay COIL(-ve) And Hook One Point With IGN ON.....!!

When You Crank .....The FC Pin Activates The Relay And It Will Power Up Fuel PUMP.....!!

Check That FC Pin Foir Signals Before Hooking It Up.......!!

For +B And +b1......They Will BE Connected To IGN Switch Via Relay And Fuse............Put Relay And Fuse(15A) If IT Don't Have One

Some People Are Just LAkeer Ke Fakeer

You Will Be Actually Connecting FC And STA Wire Also To Fuel Pump Relay As Its 5 Point 2 Coil Relay

This Diagram Will Surely Make You Understand

[SER_GTR]

Iss Actually STA Coil And FC Coil...... 2 Coils In One Relay

STA Coil Works And Power Fuel Pump While Cranking

STA Works Till You CRANK ......Once Engine Started....STA Signal Disappear And STA COil Gets Close But Then FC Goes LIVE From ECU After NE Registers Signals So FC Coils Get Activated Till NE Is Registering SIGNAL Means Engine Is Registering Revvs.....!!

Its Sole Purpose Is To Disconnect Fuel Pump In Case Of Accident.........!! The Engine Goes Dead And FC Signals Goes OUT

If its so hard to find a double coil relay then u can use an ordinary Relay (4-pins)

[SER_GTR]

Yes That's Also Possible.....!!! But You MOSTLY Find Them If You LOOK For One With Body Parts Spare SHOP

Ok im now sitting in car with my ipad and i opened the ac amplifier for connections

[chali]

Bro how to give act connections

[ecu_designer]

another cheap way of doing same thing, U can also use any low current 12v Two Relays (SPST)

[ecu_designer]

3 different ways

which colour of wire of ac amplifier to be connected with ACT
and AC1
