as some of you no i am swapping out my f20a4 for a h22 vtec the engine and gearbox and loom came out of a 5th gen so i need a 4th gen loom which i now have but it seems to have some weird electronics attached to it nicely housed in an old tobacco tin

and i have this little box which looks like a kms to mph converter

heres the lid off the tobacco tin

the only thing i have noticed missing is the injector resistor box so is this lot some sort of upgrade or maybe some sort of way of fooling the injectors to deliver more fuel

the 3 wires on the grey plug match the wires coming out the loom so its all been spliced inline

That's amazing!

So do you know what the grey plug plugs into? I can't quite tell it's position along the loom.

The connector for the resistor box has 5 wires going to it. One for each injector and an earth.

Love the tobacco tin!!!

Like you, I'd hazard a guess that this is an over-ride for the duration that the injector is operating. Can't imagine that'd make any notable difference with stock ECU and FPR though!

I'd stick a JDM Spoon sticker on the tin and get it on Ebay - it'll sell for a thousands!!!

Pity the 'baccy tin has no branding. If it did, I'd have bought it off you.
