Carburettors vs EFI Tue, 20 September 2005 23:32 Go to next message
Arrgh, my back hurts. I don't no how they can sleep, and not a chair insight.

Learning more about twin injection, there wasn't much of a point to run it. You have to run 2ECU's and all it really does it just makes the car little bit more responsive and cools the engine down better. For the cost its not worth it and there isn't much to gain.

Anyway, to the topic of the thread, carburettors have chokes and jets in the air-stream which limits peak airflow, so I don't think it will outperform a good injection system.


I would like to know peoples experiences instead of opinions and what they think.

Confused

Anyway, you obvisouly didn't do that much research if one of your conclusions is this:

Quote:

You have to run 2ECU's


I know of a particular car that I see regularly that is setup for staged injection and runs one ECU. I think I can safely assume your two ECU info came form some Jap website where the car had a zillion electronic devices all doing the job one decent ECU could handle.

Quote:

Learning more about twin injection, there wasn't much of a point to run it.


Oh dear, probably not much point in some instances and probably quite practical in other instances. I don't think you actually learnt much at all.


Quote:

so I don't think it will outperform a good injection system.



Please define "performance" are you referring to peak power, driveability, economy etc???

Here are some of my EXPERIENCES:

Living in a place that sees sub zero temps meant that my car with twin 40mm sidedraft carbies was a farken pain to drive until properly warmed up. They needed regular tuning, offered average fuel economy, had adequate top end, sounded tough.

My EFI on the same capacity engine shites all over it in every respect except induction noise.

Carbies are old school and fitting them to something now is only done to keep the car setup like it was back in its day, for the sake of being different (eg carbs on a 4AG), the owner is scared of technology or they were fitted because they were laying around the shed.

Refer to the twin injection thread which is blocked. Check the last 6 posts.
Installing two injectors per cylinder can require two ecu's.

No one is disputing that you can or could but you said:

That was what I was pointing out. Smile


Looking at what a lot of Japanese folk do to their cars highlights what can or could be done but it does not make it the best or only way to do something Wink

Refer to ke382TG's post.
Any DECENT ecu can run staged injectors.
ie, a second set of injectors turning on when you like.
Rotors run them stock.

You saw the 2 ecu thing, because ppl in japan don't used decent ecu's.
They use piggypack ontop of piggyback ontop of piggyback.

So you set the 2nd stage to come on at 500rpm instead of 3500rpm

It doesn't matter.

That changes nothing in this discussion, 2 ECUS are not required to run 2 banks of injectors whether they are run simultaneously or staged.

How's the weather in Japan Wink

I found your "reference" and this dude clearly has done this just for pose/wank factor. 180ps is nothing great and does not require twin injectors nor 2 ECU's.

Then whats the point of it then, ie by staging them you have smaller injectors that deliver a more accurate flow at low rpm in an attempt to not have huge fuel consumption, then when needed the second set of injectors chime in and add the extra fuel needed.
By not having the staged you may as well have one big set of fuck off injectors as you are just complicating matters.
Another thing to note on the twin injection drift car is it states that the transmission is only a TRD 3 speed i mean wtf.

Lol my main concern is the guys face sheesh did somebody say pull my finger Razz . Second how the fuck is he running a full original exhaust on what looks to be a 20v black top in RWD setup when they came FWD only.

Anyway I have read the old thread. EFI rules.

corona: I think thats the name of the exhaust.
And the trd 3 gears, use some common sense, just a little.

having owned:
carbi (RA23 & GC galant & motorbike)
forced induction carbi (RA40 18RCT)
EFI (MA61)

.. and have driven numerous other vehicles (i'm over 35, so i think nearly 20 years of drivingcounts for something)

In my experience EFI is the best for reliability, power, fuel use and maintenance overheads.

Tunability only comes with aftermarket ECUs (which my humble RA40 is getting) will cover the remaining gap.

As for the twin-ECU bullshit?! - what kind of cheap crack are you smoking? that has to be some of the stinkiest bullshit i've read here in the last week.

BMW 850 ran two ecus on its 5L V12, mind you it was plagued by issues of it catching fire Smile

the BMW ran 2 ECU cause it was easier/cheaper to treat the V12 as 2x 6cyl engines than develop a new ECU.

was nothing to do with staged injection.

The 1GZFE does the same, but its only so that if one dies, you can drive around on 6cyls for a while.

Welcome to the 21st century old man Wink Carbs are great for nostalgia, and they're great when they're in "the zone" but they just can't cater for everything like a well-tuned EFI setup can.
