ditching the EFI mystery box

[hondamanlxi]

similar to a carb accord i want to remove the mystery box.

ive done a 88lx,95 240sx,88 crx si but i dont know about this! The only things of importance is the map sens and the vac advance for the dist right? I need any info yall have THANKS!


ps: if you ever wanna de-emission a d or b series pm me!

[bobafett]

oooh i gotta try this on my s13!!!! i have no idea how to help you, but i agree, i think its just used for map sensor, and vacume advance for mr dizzy!

sorry, but unless you get emission free ECU you can't ditch that box.
your ECU will through all kinds of codes and make your engine run like a crap.

[hondamanlxi]

bobafet: theirs only like three vacuum line on the ka24de trash the charcoal can and cap off the line at the TB! thats all you gotta do to these newer cars

DOWN WITH VACUUM LINES!

me and justin86 have both basically eliminated the box, although he completely removed it and i havent gotten that far yet. As long as your MAP sensor is hooked up the engine will run OK. I'm throwing an EGR code right now and it runs a little rough, but when the throttle is opened up it runs better.

For ease of use, i wouldnt suggest doing that because it can become a pain in the ass to drive. i want to figure out how to get another programmable ECU so i can eliminate the useless crap i dont want/need.

aww come on give a breif how-to

you still selling stickers? ill pm u later for my order THANKS!

You need a european market ECU. That means no O2 sensor, no EGR and a lot of the shit in the vacuum box wont be used.

[Vanilla Sky]

hmm... the great dane is onto something... what about canadian ECUs?

[shepherd79]

i believe canada had all the emission crap.

[Vanilla Sky]

hmmm... i would assume the same, but that's worth looking into... i need to do some research into the emissionsless ECUs i posted in the marketplace about to see if it will be as simple as i think it could be...it would be great if i had an EFI car to work with, though... that's in the planning stages, as i still haven't gotten my tranny replaced...

[hondamanlxi]

didnt euro accord's come with MOSTLY b20s?

[Vanilla Sky]

no, if i'm not mistaken, most were a-series motors... the b series being an upgrade engine

ditch the efi box lose your dual runner intake manifold switching

[NXRacer]

if they euros dont have the emissions crap, couldnt we just get the binary out of the euro ECU and burn it onto a new chip for use in the US?

[carotman]

the EFI euro has the same crap... it's the carb version that's different.

it's not crap. all the vacuums have a purpose if you look at this closely... not like the carbed mystery box.


you could remove it completely but you'll need to hook-up the switches/sensors somewhere else.

A newer TB has the map sensor on top of it. Run an electric advance distributor and hoo-up the dual runner manifold with a H22A vacuum reserve... the only vacuum line that will remain is the EGR... you couls even use a newer valve that has the lift sensor on top of it...

No more vacuum box.
