Check engine ON and OFF when Emanage installed

[Dragtheater]

Good day friends... I bought an Emanage blue and installed it on my 4G63t evo1 engine... once installed, i start the engine.... the Check Engine Light (CEL) turns ON and OFF like there is a loose connection...the CEL is not continously turning ON and OFF, sometimes, it takes a few minutes before it blinks again... but i've already checked the wiring connections many times with the help of some technicians who knows how to install Emanage, we can say that my wiring connection is correct and soldered... i have also checked the toggle/rotary/dip switch from the Emanage and it's set at 3-8-3... and also all the jumper wires are in their correct places...

if i remove the Emanage and start engine, the CEL doesnt blink at all..
what do you think is the cause of the CEL blinking when Emanage installed?

i have a MINES ecu...

thanks and hope to find the solution as soon as possible...:)

Have you checked the parameter settings within the emanage itself? It's a different setting all together aside from the rotary switches. You have to have the support tool cable and software, the software you can download here from the downloads section and I reccomend Giff Tech's usb conversion cable, its like half the price and Giff does great work.

Anyhow if you bought the unit second hand then it's likely that there are unit settings preloaded or locked into it that sending bad signals to your ECU. If you're connections are 100% right then that's the culprit. However I know for certain the emb manual is incorrect when it comes to the pinout diagrams. We also have pinouts loaded into the download section. Check those. Those are the two options that are telling me whats up. From what you describe the information is getting to your normal ecu just fine from the sensors when the blue isnt plugged, but when it becomes an intervening factor the information sent is being bad. I reccomend getts a code reader from the local auto zone or something. Plug in the emanage ultimate and when it flashes you the code, log it and post it here then i can look it up and tell you exactly what packet of information is being rendered bad by the emanage.

Oh and welcome to the site btw!

[Dragtheater]

thanks for the warm welcome sir...

what parameter settings are you talking about?

the tuner had already reset the EMB before tuning it... so i think theres no preloaded or locked program inside the EMB.

ill check the wiring diagram from the download section for me to double check the connections...

another thing, what code from my EMB do you need sir? and why do i need the Emanage Ultimate?


thanks :)

[Accord2nrz]

lol no need for the sir title ;) My bad about the ultimate, I responded to your email after working in 115 degree heat for awhile. I want to know the DTC code from your Check Engine Light. (Diagnostic Trouble Code) like P0401 or something like that. It'll tell me what sensor is showing as false to your ecu

[Dzaster]

And the jumpers and rotary switches are all set accordingly?

i tried to diagnose the ecu for trouble code of the Check engine... but it shows no error codes... some says the problem is my mines ecu...

[Dragtheater]

yes...

[Dragtheater]

Help!:(

I thought I read something about there beign problems wityh emanage and the coil packs of certain EVO's. I really have no idea if this pertains to your car though.

Maybe you can try and disconnect just the ignition wires and see if the car runs with emanage and no CEL light.

[Accord2nrz]

Snap good call! I forgot to ask do you have the igntion and/or injector harness installed also?

[maxgtr2000]

I've heard of issues on certain vehicles that use the ignition harness, usually melted coil packs. In the maxima community we soldered diodes on the ignition output wires from the blue going to the coil and that solved the issue.

hi, if u install emanage on 4G63 or 4G93 the CEL will blink, because mine and my friends did blink also... still cant tell whats the problem, but the car runs fine.... it blinks only for a while... my tuner said something to do with the mitsu engine system....

[Dzaster]

Here is the thread I read it in, about the ignition system in mitsubishis.

http://www.dsmtuners.com/forums/420a-engine-management/275731-emanage-blue-ignition-fix.html

There may be more discussion on the net but I never looked any further.

[Accord2nrz]

I remember now, the ECU system in the mitsu is a bit more intelligenet and resistant to tampering I believe the blinking is to let you know that the ecu knows its being tampered with somehow. It's wierd.

yes...

thats what my tuner said also... hope someone could help us clear things regarding this CEL blinking issue...

ive already ask Greddy about this but they didnt reply...

[Accord2nrz]

Trust USA has no idea why it happens. I tried talking to the japanese company but they talk way too fast for me to translate. basically the mitsu's ecu doesn't like being tampered with and it can tell. You have to reflash the ecu to take that feature out to keep it from blinking.

[Dragtheater]

ah ok, so are you telling me that reflashing is the only way to tune and remove the blinking CEL? or is there any other way?

[Accord2nrz]

not to tune, you can tune using anything. However the only option i can think of right this minute is to reflash the ecu to remove the CEL blinking notification deally.

[Dragtheater]

for me, reflasing my ecu is not an option,since i have an aftermarket ecu... any other options?

[Accord2nrz]

umm.. your running an aftermarket ECU with the Greddy E-Manage? How on earth did you get that to work?

[Dragtheater]

yup... im using MINE'S ecu which basically set to 100 octane rating for the gasoline... since im here in the philippines, there is no such octane rating here... so i use EMB to avoid the problem of engine knocking..

[Accord2nrz]

oh wow, in that case I am almost clueless. octane booster could help or look into snow performances' water methanol injection system. Should help with the knocking.

[Dragtheater]

can i use av-gas (aviation gasoline)?

[Dragtheater]

im still clueless on how to remove the Blinking CEL...:confused:

[Accord2nrz]

not too sure about the aviation gas. JP8 is not really engine friendly as far as I know. Turbineguy may know more of the functionality behind jp8. I know for certain it would not be cost effective at all.

[BOOSTED_CRX]

yea i think theres somthing with the emanaged interfering with the car ecu. Does the check engine flash like its throwin a code or flash like it is a loose wire like dims in and out. Cause the emanage is known for makin the computer throw codes becasue of the parameters or for not upgrading sensors on the engine lol buts thats just my theory.

[Dragtheater]

my Emanage blue flashes like it has a loose wire... but i've already checked it so many times.. no faulty connections!

[Accord2nrz]

If your lights on the emanage are flashing anything but RED then you're ok. Even greddy does not know why they do that. Those things have a mind of their own :)

[RPW00Mirage]

Few things i was curious about.

EVO1 motor in a 5G lancer? why? you would have to fashion all new mounts, move things around on the firewall and move the crossmember. FWD? the wiring? not to mention obd2 vehicle, obd1 car...

on the opposite, if you did swap it in, i admire your work and excellent job! i'd love to see pics, and most likely so would my board www.mirageforums.net


you should be able to run the same DIPS and settings for the EMB as a DSM/early EVO. i think the settings are even located in the manual.


what color is the flashing? mine flashes colors often, usually green/yellow.

[Dragtheater]

yup, because evo1 engine is cheaper than evo4 engine here in the philippines...yes,its FWD..
yes i have same dips and settings as the DSM but the thing is, the Check Engine Light is blinking ON and OFF... my EMB is flashing green/yellow..
heres the pics of my car:

this is my 1st transplanted engine (before):

and this is my engine now (present):

[Accord2nrz]

looks really good, the green/yellow flashing is "normal" for the emanage.

the CEL blinking, is what we're focusing on. were you ever able to pull the code its giving?

[Dragtheater]

i've already tried diagnosing the ecu, but the MINE'S ecu doesnt read any trouble code..:(

[RPW00Mirage]

he's OBD1 now, cant use the data connector to pull the code.

i'm not sure how to pull the code on DSMs/early EVOs....

[Dragtheater]

he's OBD1 now, cant use the data connector to pull the code.

i'm not sure how to pull the code on DSMs/early EVOs....



are you sure its OBD1? some says its OBD1.5

[Dragtheater]

OT: i have an O2 sensor installed at the exhaust manifold... question is: do i still need to install the second O2 sensor which is located at the catback?

whats the use of the second O2 sensor? is this 2nd O2 sensor connected to the ECU?


i dunno but maybe this is the answer to my question...

[Dzaster]

Usually the second O2 is there to monitor the health of the cat. I'm pretty sure it communicates that to the ECU.

[Accord2nrz]

it does, but if you didnt have it on before the emb was connected and the CEL was not on then that is not the issue.

As far as pulling the code, do a search for how to pull the code from the ecu using the pin jumping method. It's old school from the days of the 80's series camaro and earlier, when GM made a "key" that jumped two pins on the OBD connector which causes the ECU to flash a code.

[Dragtheater]

i've already jumped two wires from my ecu to get the code but i guess the mine's ecu doent want to get diagnosed...

i installed a different ecu (rvr) to my car and there you go, the CEL continues to blink, that means theres no engine trouble...

and when i put back the mines ecu, the problem is still there...


HELP!

[Dragtheater]

i still have CEL blinking on my panel gauge..:(

[L4nc3r]

i also have the same problem.
installed EMB on 4G93 DOHC and 4G92 SOHC (evo3 body)
it's caused by injector. without the injector EMB has no problem.
but without the injector correction what's the point? :D
solution is upgrade to EMU.. :D
