are the jumpers correct on the internals of the emanage?

if the cells are at zero then it will just run the original ecu's map as its not making any adjustments, it doesnt matter if that map is selected or not

Hi Dale,

Yep all jumpers are set to the factory settings. That was what I thought about the maps too, but I don’t understand why its saying there is an issue with channel ¾ when I only need ½.

I also don’t understand why if all the maps are set to 0 the engine runs badly, yet as soon as the emanage is disconnected it runs perfectly

Cheers

the injectors fire in pairs so it shouldnt need 3 and 4 connected and it should know this from the jumpers. youve definitely connected the injector ground wire right? on the emanage main plug with the clip part facing upward and looking at the back where the wires go in, this is the bottom left wire (in the pictures i sent you its purple). this would cause issues.

if you cant get the problem to resolve itself then maybe try bridging 1 into 3 and 2 into 4 on the injectors. it wont hurt because youve got no output wires attached, it might just get the emanage to ignore the error?

the other thing to check is that youve set all the jumpers 100% correctly. and also that youve set the dials on the back of the unit. bearing in mind 3 of them are hidden until you take the case apart. one of these dials is the "number of cylinders" selector (far left) which would definitely be messing you up if its set wrong. bearing in mind that the cylinder number should be set to 2, NOT 4!!! this could definitely be the problem if youve set it to 4.

also youve got the 5 visible dials on the back that are airflow correction adjusters to lean/richen the fuel at 5 predefined RPM points. i cant remember off the top of my head what the RPM points are. just set them in the middle for zero adjustment for now.

Dunno about the JDM ECU but the UK mk1 MR2 ECUs have a single injector driver. All 4 injectors fire simultaneously. So as long as they are all connected and healthy then if one fires then they all fire.

Does the emanage have its own injector drivers? Does it replace the stock driver?

Yep injector ground is connected up correctly.

That was what I was planning on doing to see if it prevents the code. Seems strange though, have you had to do this with you unit?

the other thing to check is that youve set all the jumpers 100% correctly.


Will pull the board tonight and check again.

and also that youve set the dials on the back of the unit. bearing in mind 3 of them are hidden until you take the case apart. one of these dials is the "number of cylinders" selector (far left) which would definitely be messing you up if its set wrong. bearing in mind that the cylinder number should be set to 2, NOT 4!!! this could definitely be the problem if youve set it to 4.


The 3 hidden pots were set to 2 4 2

also youve got the 5 visible dials on the back that are airflow correction adjusters to lean/richen the fuel at 5 predefined RPM points. i cant remember off the top of my head what the RPM points are. just set them in the middle for zero adjustment for now.


Yep all 5 dials were set to 0%. I didnt adjust the other 3 as they relate to VTEC and as I haven’t set the VTEC jumpers they shouldn’t be active.

Well I checked the jumpers - all fine.

I also checked all the leads and connections all fine.

I re-read the manual and it states that if you dont have the same number of injector cables as you do injectors then you need to group them - 1/2 3/4 so popped in 2 new cables and hooked these up.

No code 23/24 which means the emanage is picking up the extra channel signals.

Still idles rich and stumbles when revved though!

Now I am not sure the crap running is anything to do with the injectors. I noticed the Emanage flash code 11 - Airflow/Map sensor incorrectly wired? Yet it is correct, at least in line with the diagram - could this be wrong, I will do some testing tomorrow to see if they have marked the wrong cable for tapping.

I left the Emanage connected but unplugged the Map cables and put that back to stock and it ran alot better and revved up nicley etc. Need to test it properly when I wont p1$$ the neighbours off. Dosnt run as nicley as it would do as stock though.

Typically disconnect it all and it runs sweet as a nut. :( I suppose some consolation the car is still usable and easily reverted back to stock.

Aye, showing TY PR3 which is correct for the engine.

The AAV RPM setting boxes were left at the preset RPM points and the adjustment values set at 0.

Injector box was left empty as they are factory injectors.

Didnt touch anything else other than selecting the maps I wanted.

Ignition timing map
Additional injection map
Airflow adjustment map
Anti engine stall setting

Oh and set the TPS up.

It even automatically populated the engine model box so its shopwing as a 3sge / 4age. Going to compare the wiring set up for the 2 and also see how they compare.

More fuel for the fire ... wooo.

I did a data trace with the engine running so I could track back over the info.

Picked a few basic values to monitor.

RPM,
TPS,
Airflow in,
Airflow out,
Airflow adjustment,
Injector duty,

So anyway looking back through the grap the Airflow is showing volate in, but nothing going out? Airflow adjustment says -1 yet all maps are 0 and exported to the Emanage.

Strangley injector duty also shows 0. But this was taken before I connected the other 2 channels up so many that screwed things up with that reading.

This is a joke it's all wired correctly and still runs like xxxx. Sigh. Think I might just punt it on, not like I can find any evidence of people making this unit work on a 4age.n

I cant think of owt else that you havent covered :? it seems very strange. When I put my emanage ultimate on, I just wired it in, turned the key and it was perfect and as no maps had been edited then it just read and ran from the stock ecu.

All I can think is that you are going to have to go over the wiring again, jumpers, parameters, surely it has to be one of those. Im selling my emanage ultimate now as im going a totally different route!

Bit miffed really, been over everything multiple times everything is set properly and I cant find one person online with any documented evidence that they have got the unit to work properly on the 4age.

Its amazing the difference is night and day - unplug it and the engine is a peach, plug it in and its xxxx.

I did say a few months ago a stock 4age is bliss, it just works - why did I bother?! POOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO


How much you selling that Ultimate for Dale, drop me a PM if you prefer?

I will try changing the airflow sensor type and see what happens. Found something detailing the switch settings as 240 rather than 242 which is in the manual.

have a word with Nathan Freke, he was running an emanage with throttle bodies and made 207bhp!!

think his name on here is Century Motorsport

also the best source of information i ever found for the emanage, bearing in mind this information was all being discussed about 5 years ago, was the club4ag forums.

Tried Nathan a while back but no luck. For a system thats been around for years you would think the knowledge base is huge - maybe people dont like sharing!? :(

I have trawled club 4ag on the Emanage and read alot of drivel, and it seems as a whole people avoid it there are a handful of people who have got it to work but thats a handful and its only word of mouth and nothing reliable or usable.

Sigh ... what a waste of time. Should have just saved for OMEX!

Hey Tiny if your interested I will do you a good price, its a great unit ... 8-[ :-k :mrgreen:

maybe you just have the wrong wire from the orginal loom?
get a multimeter in the tps and check its actualy ok and work down the wiring from there.


The 4E-FTE MT TPS - is just closed or WOT. No linear region.
