Last resort

hey guys i cant afford to come up with the funds to replace my aftermarket ecu that never got sent so iv got to get rid of my 660cc venom injectors.the engine hasnt been turned over for almost 2 years and its got almost everybolt on you can imagine,so im dying to drive it asap.im gonna be replacing them with 440cc yellow injectors.how can i run those in a 89 rs legacy.is there a factory 4 plug ecu that ran 440cc injectors from factory.i dont really want to have to change the loom.cheers.

the last time i drove my car all it had done to it was

dsr front mount

td05h turbo

wastegate

2.5" exhaust

stock block

chipped ecu running 9psi

since iv driven it iv done some things like

flipped intercooler and twisted turbo setup

Hybrid td05 with custom mse wheel and cover

sti v3 internals

sti throttle body

custom 2.5" to 3" exhaust

custom exhaust manifold

alloy radiator not a crap one

split rail

walbro pump

4" intake

electronic boost controller

sti brakes

braided fuel,brake oil,water lines

and so on

iv spent about 10 grand on my car since i last drove it

One option you could look at that is cheap that will run yellows is to re-pin the plugs to fit into a 3-plug ecu and get an STI ECU. Will also need to find an AFM to suit aswell. There is no 4 plug ECU that will run yellows without being chipped.

Three of the 4-plugs are physically identical to the 3-plugs of a 3-plug ECU so they just require the wires to be swapped around to make them work. Other option is a chip that has been mapped to allow yellows to run on the old 4-plug ECU.

hey thanks for that Koom,that dosent sound like to bad of an option.can you expand on which three 4 plug ecu's are identical to the sti v3/4 and where could i find a rewiring diagram.cheers ohh and i dont have a/c so would that benefit my way with this situation cause i heard the a/c runs almost one whole plug coming from the ecu

[Guest boostcut]

have you tried to run the yellows? coz i have a gizzmo computor that runs yellows perfectly.

I meant 3 of the 4 plugs are physically the same. There's wiring diagrams for the 4-plug ECU's that I made in the Legacy area (try Reuben's single turbo thread) and links to 3-plug STI pinouts in the Impreza tech section I'd guess. It does take a bit of work and depending on how good you are with researching and methodically swapping pins in the plugs it could be easier to run a chipped ECU as boostcut mentioned his work's but the re-pinning is still an option.

[4ORGD]

what sort of car is that in boost cut? does that ecu youve got have a price tag on it by any chance.or even a deal witn my 660cc injectors

[Guest boostcut]

v2 wrx non sti. i didnt even realise that the comp wouldnt run them but mine seemed to work so give it a go.

[Guest]

Get a 4 plug v1-v2 wrx ecu and throw a chip in it and it should run mint with yellows, save the rewiring to a v3-v4 ecu.

Will those 660s fit my v5? If so id be keen on a deal for my V5 440 yellows.
