It doesn’t matter how many times I ask there’s no limit, on this forum or anywhere else in life, and guess what isn’t not up to you

there’s is no reason for you get involved anyway, but you obviously TROLL forums looking to post useless remarks

If you have nothing useful to say then please why bother to respond, you’ve taken it on yourself to add your useless TROLL comment 

No one was tapping on your screen or banging on your door, you just logged in of you own free will to do WHAT ? Nothing

Hopefully others will respond to you with the same downbeat manner, having looked at some of your responses on other threads I can seen that you have “know it all demeanour” well aren’t you the lucky one that knows everything and doesn’t need to ask anyone about anything ever again.

Please feel free to Foxtrot Oscar, I’m sure the forum will be a better place without you.

 Once again, thanks to the forum members that did make useful contribution

On an Atom you can theoretically connect a 0-5V output from an external knock amplifier box to one of the spare analogue inputs, but you can't do anything with it as there is no knock control section available in the Atom ECU 

OK, so that's where I've gone wrong !!

However, looking at a basemap would mean little or nothing to me and/or would just lead to ore questions, which are of little use really, as ultimately I'm bound by the capabilities of the chosen ECU.

once again, thanks for the input..... be it analogue or digital

Incase you still don't understand. ATOM DOES NOT HAVE KNOCK CONTROL. 

No need for the superior tone mate,

Remember, The only stupid question is the one that you forgot to ask

and FYI "In case" are not one word

Keep in mind that the atom isn't capable of accepting a knock sensor signal, if that is still on your "want" list of sensors, as stated earlier you'll need to go with a storm if you want knock input

Surely you're pulling my leg.. That's what this post has all been about.

I know that the storm has on-board map sensor but the engine has it's own which shield be fine,

I was told that the analogue inputs can be assigned to be ANY function including knock control from a knock sensor.

Can someone please give me a definitive answer to this as I am about to buy one , maybe this week.

Thank you for the response to the original post.

As is often the case with when venturing in to a new realm, such as in my case replacing the old ECU with relatively old technology to a bang up to date one, it's easy to be get overwhelmed by amount of information that is available on-line BUT Information is not knowledge

Looking at ECUs and their capabilities and terminology is something that I have had zero interest in until now and I’m sure that once I have sourced one and had it fitted and mapped I will have no reason to go searching the net with regards to this situation for quite some time.

So when embarking on the search for an upgrade, all that I had to work with is the specification for the original ECU, and bear in mind that in 1991 this corolla and it’s engine was way ahead technically than most of it’s competitors.

So what you find on manufactures websites is basically jargon to the uninformed, and what I have found when requesting information , is that the responses in many instances, implies “What’s the matter with you “ are you stupid”, “ what don’t you understand” ...........

So No , I’m not stupid , quite intelligent actually, just not been following ECU technology for the last 20 years.

What I do know now, is that the inputs on the ECU can be programmed by the installer, to be any of the items that I need, such as TPS, Knock and MAP etc, and really that’s mainly what I was missing.

So I have decided after speaking “On the phone, with a real live person” the UK sales manager,  that the G4 Atom will be suitable ECU for my needs and now I just need to narrow it down to finding a capable local installer that can get my ECU mapped and set up correctly.

Thank you for the replies and a big thank you to the up-loaders of videos on YouTube without who’s help I would still know little or nothing

Thank you for the replies, It's all very informative but what I haven't been fathomed out from here or any other forums, why us the the knock control IS NOT REQUIRED, on a modern ECU ! The knock must be managed somewhere surely.

Also what about the MAP sensor ? my car has one, it's wired into the ECU, so it must be doing something and if it's no longer required by a modern ECU .. How come.?

I'd really just like a better understand of why these features that were once important, no longer are.

I watched a Haltech youtube video about tuning out knock and it was very interesting and it sort implied that tuners tend not to be bothered about it

Here is a link

The guy seems to know what he's talking about but I'd be please to hear views about it

The reason for knock control in the OEM ECU is it had to run the engine safely on a huge range of fuels and huge range of intake temps - anything from the premium fuel it was designed for all the way down to the poorest quality columbian 70MON fuel.  

I doubt very much that the ECU for the UK 4AGE Corolla would have designed to run on the same fuel as you might find in Columbia.

The ECU part number for the UK model is unique to this car/engine combination, in the UK we never get anything less than 92 unleaded

Some searching of the website would have saved you a lot of headaches.

 

Mate, I've spent so much time searching the internet about this ECU the wife nicknamed me Google.

Looking at the spec chart that you have posted I don't see MAP sensor anywhere

Thanks for the input it's really helpful

[phil till]

It's not a case of "if I want knock control" the engine has it and it needs it to run smoothly

a few years ago I blew one these engines

I then spent ages trying to find another 4AGE and eventually found one from a breakers yard, what I didn't know as that the engine I bought was an earlier TVIS version without a knock sensor.

By the time I realised it was too late, the engine was in the car and there was no way retro fit the knock sensor to the engine

The car could not be driven properly as it would hesitate at traffic lights and traffic island, or under and kind of acceleration, it would knock and vibrate.

I traded the car in for another to get rid of it

So really what I need is an programmable ECU that can handle  an external knock sensor and and external MAP sensor.

The supplier in the UK Fensport told me that the link atomG4 would be suitable for my car but you are telling me otherwise.

So as it will cost around £1,000 I really don't want buy something I find out to be unsuitable the day it's on the ramps at the tuning shop and the guy tells me I wasted my money.

The engine is stock other that hight lift cams

It won't ever be boosted

The engine as it's own KNOCK sensor screwed into the cylinder head,

If I disconnect the knock sensor from, the engine, the car is undriveable

Why would I not bother with knock control,  the 30 year old standard ECU has managed it

[phil till]

I have contacted many ECU manufactures including Link to determine what would be a suitable ECU for my UK spec 1991 Toyota Corolla Gti-16 valve.
The engine is the 3rd Generation 4AGE and has it's own KNOCK sensor and MAP sensor but does not have O2 sensor.
I had narrowed down the ECU options to the Atom G4+ but have had conflicting messages from Link support
So, before I click the buy it now button and possibly end up with the wrong ECU.
Can some one confirm whether or not the Atom G4+ can manage my KNOCK sensor and MAP sensor

Eventually Purchased an Emerald K6 ECU , from Emerald UK,

They were able to supply a Plug n Play loom to connect the Emerald K6 directly into the Corolla wiring loom for £60
