Dazza, no they don't, it was a good point above about adding one. Would the el ecu still work without that? I've heard the are not an essential for the computer to function, it just tells the computer when to kill the engine, but I am open to correction here.

Well I guess if an EB doesnt have one, then my EB definately doesnt and it runs fine.
If any of the smart guys are reading this, is there any advantage in hooking a knock sensor up? I see that it runs out of pin 23 on the ECU.

You have a BBM on your EB Dazza?
If you didn't put a knock sensor on yours I guess it isn't a real issue then.

Yes, any smart people (and that's intelligent smart not smart azz smart lol) have any ideas on the actual function of these things?

Basically designed that when the motor misses real back and gets a big vibration this thing generates up to 3v I think and feeds it back into the computer... The more volts the worse the knock and the computer acts accordingly in whatever way its been programmed to eliminate the knock...

Yes you guys are right if its not fitted to the block and hooked up then if you get a knock the computer isn't going to know... But EA-ED didn't have one and never had a problem... I think with EF/EL it was more insurance for reliability...

When the EL computer goes into mine I wont be adding a knock sensor...

Lowlane, when I said maps I didn't mean the map sensor... I meant the maps in the computer... Spark maps, afr maps, that sort of thing... They are different between the log and BBM and hence the computer to suit the BBM has the right maps built in and works most efficiently for that induction length... think of like maps in your navman... just its internal instructions on what to do at each fraction of a cycle... so to speak...

Cheers...

Ohk, misread that one. Thanks for the info though.

I was thinking too, I have a map sensor off a ef in mine an didn't make a diff.
Blonde moment I spose. Lol.

I think you might find that the map sensor carries the same part number from at least EB to EL. Cant see why swapping them would make a difference. I know if you disconnect it it will definately make a difference...

JOSE,

It can be run off EA-ED computer with the addition of an RPM switch... Such thing can be bought from as a kit from Jaycar, you make it up and set it to the right rpm and use it to trigger the solenoid... MSD do a similar already made up part that does the same thing...

Trouble with running an EA-ED computer with a BBM is that the maps in the computer are for a log manifold... So your best to run the EL computer that has the right maps to give max benefit and then you have the added advantage of having that trigger pin for the solenoid...

Hence why most people go for the EL computer over the rpm switch...

Cheers,
Tim


yes i am aware of that, this thread was started as the OP wanted to disprove his mates claim that an ED will function with a BBM without the rest of the gear, i simply wanted to add real world evidence that IT WILL WORK, the long runners are longer than those of a log manifold, there does seem to be more low down power with it set to long runners and i do a lot of towing so i left it like that, im sure if i hooked it all up properly i would see the full benifits of the BBM setup

oh, and the knock sensor is there so the ECU can adjust the timing, it pretty much works so that the ecu advances timing till it detects knocking, then back off a bit - its why newer cars dont have to have any adjustments made to get the full benefit of higher octane fuel

but yet I can run an EL computer in my ED without the knock sensor... so it can't rely on the knock sensor for normal operation... It must be only there in case something goes wrong and it detects a knock and then retards or advances the timing (whatever fixes the problem)... It can't be trying to make it knock then backing it off a bit... otherwise an EL computer in an ED without the sensor would near not run...

That makes sense doesn't it? :?

Cheers,
Tim

id hazard a guess that the ECU can detect if the knock sensor is there or not (or if its failed) and will just use the timing as set by the dizzy

the knock sensor only removes timing when it detects knocking, no knock sensor or no knock, it just runs as per std map..

I wouldnt even say it takes any great effort. If you have the smarts enough to know that when turning a spanner, righty is tighty and lefty is loosey, then you should be able to swap a manifold over and hook up a few plugs. I think I forgot to add that you need to swap the dipstick tube as a step on my how to guide.
ed2dy4 mate, I wrote that step by step guide as I was doing the conversion. It is easy to do, and if you also convert to thermo fans your ED will be just as pokey as an EL. My EB is about 25% better than what it was with the log manifold and clutch fan, uses less fuel, makes more power and more importantly more torque. There are no modifications to the head or engine, and if you have a wrecked EL then everything you need will be there. My advice to you if you are contemplating the conversion is use the EL, not the EF even though the manifolds are the same, as you need to use the computer from the donor car, and the EF computer wont run in an ED as the EF has coil pack ignition and the EA - ED and EL use a Dizzy. I think you should tell your friend to stfu and research things before he opens his yap. If you have any queries, drop us a PM.

Edit, I think I should stfu before I open my yap. Youre mate is dead right, you can bolt them up direct to the head, and not hook up the BBM solenoid and the car will run. To extract all the goodies from the BBM you need the ecu from the donor car etc, a little wiring modifications and about 6 hours of time to spare start to finish. He doesnt need a smartlock bypass as both cars have smartlock. You are the one who is proven to be wrong.


well he is talking about a ef!? also what about the smartlock? or can you just straight up change from a ed to a el computer???

Only EA an EBI didn't have smartlock...

You can put an EF BBM on the motor... But you must run an EL computer... straight swap... no smartlock issues... no nothing... plug and play...
