Gabro chip fitted today.... but

[fatboy]

I only managed about 5 miles before it mis-fired and stopped. Got it running again but mis-firing and EFI randomly appearing on dash display.
Conneting diagnostic lead showed DIAG 0.
Swapped ECU over to Forza chipped one, ran fine for a mile, then repeat of above, then not running at all.
Visual of wiring seems fine, no flash at all from test lamp on injector wiring, Cannot hear fuel pump priming so would seem pump relay at fault.
Would this cause the EFI on dash display ?

Hi all,

Have you checked the air sensor connection in the right-hand air duct?

[fatboy]

Thanks Greg, no not checked that but have established no power to fuel supply side ( again ).
Now some major wiring tracing issues to be done.
I did suspect RH bar kill switch as power to ECU seems to come from there but engine turns over, no power exiting ECU from green/black wire to fuel pump relay and rest of fuel supply side.
I did notice a split in breather/airbox pipe and wiring below covered in oil.
Im now out of my depth here, ring Griff again tomorrow.
I think I love my Falc more than it loves me

Do you have an alarm fitted?

Take the rear surround cowling off before you call griff

[Aladinsaneuk]

Oh

Check the fuses - right hand front fairing

Numbers 1 and 3 are part of the ignition / fuelling cycle...

Thanks Alad, how much do I wish it was just a fuse....?
First thing checked. No alarm fitted, checked tilt switch, anything else I could think of.
Didnt get chance to look today, much wiring to be traced ( phone a freind time )
Just got that feeling that its gonna need a trip to AP.
Fix the bike or new clothes... fix the bike !

did it have an alarm fitted?

if so, there is likely a bridge that is loose or lost on the left side.....

ask me how i know!

.... reported to you by Green Flag along with may other problems they've rescued you from ?

No

Much prodding and probing reveal no voltage to the ECU. Have power into and out of RH starter/ kill switch but then vanishes somewhere along those yellow/red cables.
Bit of a wind up as I can hear both injector relays switching, then they stop/start/stop ect.
Im thinking a broken wire somewhere near the RH switch where the wire moves/flexes, which would explain the very low fluctuating voltage
If anyone could provide a colour print out of a Falc wiring diagram I'd be happy to pay every exppense incurred, Im reading off an RSV diag, similar but not exact

Can't do that but this is really useful in identifying particular circuits:

Thanks D-R !

be worth checking the operation of the diode module while your at it, IIRC there is a simple enough checking procedure described in the manual.

[fatboy]

That was my first suspect so I rang Griff (AP). He was doubtful as he has only had to replace 2 in over ten years.
I have power to injector relays, power into pump relay but no power out, from my understanding, the diode, when it operates relays power to the ecu,where I dont have voltage.
Would this cause the EFI warning on dash display ?
