D16y1 into an ED = 2 ECU's??

[Val]

Hey im getting a D16y1 VTEC done into my ED3, do i need to have 2 ECU's to run it?? That what the mechanic told me, i need one for the dash instruments and aircon etc., and the other to run the engine but its sounds sus. Can anyone confirm/deny plz??

[VTi_b0i]

LOL thats the 1st tiem ive ever heard that in my life! all u should need is the d16y1 puter in which i have if u need (p28)

[bennjamin]

it should work all off the D16y1 ECU. Your mech should be able to rewire it so the ECU controls all the ED's accessories too.

lol,

one ecu will do the job

I thought it sounded dodgy when i heard it, just wanted to make sure.

[ECU-MAN]

get another mechanic ( in a nice way )

he will probably add his cut to all the prices

[JasonGilholme]

nah man 2 ecu's makes it better!

Get a new machanic dude. lol

[SINISTR]

2 ECUs? mmmm... should tell him to install 3 or 4 cos you heard its better still! 1 for the engine, 1 for the aircon and cluster, another for vtec and maybe another one for the fuel pump?

[Edgeauto]

lol, somepeople shouldnt be allowed to touch cars

[panda[cRx]]

lmfao, just make sure he doesnt overcharge your for your headlight fluid or muffler bearings!!

[SINISTR]

all jokes aside tho ... the idea of two ECUs is pretty riduculous really, I'd be warned of going to this mechanic for any type of major work, Minor work like oil changes etc you can do at home yourself.

Its the last time i went to this guy... But my car still has the old fuel pump intank(mechanical), and also addition of a new external pump(electrical) for FI setup on D16y. So it will be running 2 pumps, does this change anything??

[SINISTR]

You shouldn't have to run two pumps. You should change the tank from the EFI car as well so you're running only one fuel pump!

[Val]

I asked my mechanic to use one from an FI car, but he said its easier to use an ext. pump, so that they don't have to cut into the tank?? And also it costs about $500 extra to cut in.

[SINISTR]

the tanks I believe are interchangable - the only thing that needs to be changed is the wiring, since its electronic...

Let us know how you get on Val, I've bought an ED sedan recently and a fren wants to buy it off me provided he could turn it into a sleeper with a higher output engine ie B16A but our main concerns are the costs EFI conversion, fuel tank+pump/wiring, A/C hook up and cable clutch setup on later engines.

Mechanical fuel pumps are not intank.. how do they run if its mechanical???

clowns... ur mechanical fuel pump runs off the camshaft like every other carby engined car ever built.. You'll be running one fuel pump and it would be External unless u change the tank which r interchangable

Im going to be doing a B18C conversion on my lil ed myself (i am a mech after all) and im not gonna change the tank.. its easier just to fit an external pump.
You also need to change ALL the fuel lines to EFI lines as carbies generally dont run much over 3-4psi.. and thats after the almost all the fuel line.. They explode when runnin efi pressures.
