Need Help F/I guys--E-ultimate issues

[Rio Trix]

Ok guys. Help Please!! Need Ideas to try
Posting for a f/i friend..
E-manage ultimate on a turbo 2zz..
heres what happend.

Car was running perfect..(I mean really perfect all the way up to this point>had a need to unhook battery.
after battery reinstall-car feels like its in limp mode
runs increadably lean (a/F was perfect before-will crank but obviously should not be driven)
Emanage has red light now was green before battery unhook.
went into emanage program and map IS still there..

^^^^This is truely odd ,because this exact same deal happend on my ATR kit right after ATR went bankrupt -leaving me with no options but to send my car hass for a better kit and better engine managment..(speculation then was ECU was kinda fighting with E-Blue)<<now Im thinking that wasnt it all along.. :unsure:

There has to be a simple awnser to this issue..
Need your help guys :unsure:

Currently gonna load map up again see if anything changes :mellow:

maybe there is some sort of backup battery missing or something and it lost the tune. I dont know.

I thought that red light on e-manage = internal problems or some such? I don't recall - call Greddy and ask them or read the manual maybe

perhaps Not sure...were gonna reload map again tommorow (maybe map became corrupt somehow)

Update **unit has green light now but problem is still the same WTF???

manual says
Offline =yellow
online=steady green
real time communictaing=flashing green
On line recording=steady Red

Make sure you are running the correct map. The dipswitches determine whether you are using map 1 or map 2 for the inj adj and the ign adj (only one map to accel inj and accel ign).

If you have map 1 loaded and activated on the map tree (selected on the car parameter menu), but the dipswitches on the unit are set for 2, I'm not sure it will even read info from map 1.

im not to sure about the US but in Aus we have managed to get the PFC working in the corolla's with the only problem being that the stock temp gauge wont work anymore and sometimes it has some idle issues when the A/C is on but other than that everything else is fine. Has anyone given it a crack in the US?

Sorry 2 hijack ur thread rio trix ..... as a piece of help is the MAF sensor on the car ok as it might be recording that its lean when in fact it really isnt ?????

thanx jiltman well check that



we did get some info on the last night(it wasnt to good though)
Ok heres the possible senerio:
seeing the e-ultimate is a piggyback,the stock ECU continues to function almost normal..When we unhooked the battery the stock ECU was reset clearing out trims...<<the perfectly tuned map for the e-manage was tuned based on exsisting fuel trims (now that they are gone car runs like crap) seems like the only logical thing to do is re-tune the e-manage grrrrrrr!!!dyno time and all...double grrrrrrrrr!!!
Its doubtful that just driving the car a while out of boost will get the ecu back close enough to get the car to a decent state,especially seeing a/fs in the 16s now..*not sure*
Now the question lies as to weather its best over all to reset the ecu right before any tune is ever put on a car with a piggyback or youll likely face this issue over an over(dead battery-need to unhook batt,)..If thats the case maybe a emangae map that was made on a ecu with no short/long term trims yet would be idle,that way you can always reset the ecu and fall back on the map for that situation..

We all know Hydra and PFC is hands down the awnser to not having headache after headache.But in this situation the car was doing great til the batt. unhook.

whats your thoughts guys?? seem to be logical??

Hey No prob.Zoom glad to talk any info ..

Noone has tried a PFC on a corolla or Matrix yet (really dont know why-I think it would be Idle and a little less pricy than Hydra) I guess everyone just wants the easy route.seeing noone has a working harness ..I choose the hydra myself (and am very happy) I do have the same temp gauge isssue you speak off and as to AC issues ,we had those at 1st but now have corrected all of them (with help from Hydra usa) they will be addressing the temp gauge issue in the next version I hear,which is due out very soon..
as to the MaF ,yes this was a thought of ours as well(maybe we fried it somehow)<havent ruled it out just yet(need to test it)
Thanx for your thoughts Zoom

It would be if anyone with a Corolla or Matrix would swing by my house so I can take the measurements I need to make a patch harness.

My thought is this: When he tuned that E-Manage he probably did so with a bunch of fuel trims established in the stock ECU. When you reset the battery those trims went back to nothing. He needs to retune to eliminate any fuel trims.

I so agree with you Boosted,We acctually have a guy in Katy Tx, that just installed a kit with E-Blue and we tried and tried to get him to go to you for the PFC (it will be better 4 him and help lots of others) but now he says he,s broke from the turbo build..Grrrrrrrr!!!

We will continue to try on both forums.many guys want this badly but sadly are to far away..

I fully agree !!! odds are your 1000% correct!

hey rio i hope u and your friend find out whats up i to am going to instill that e manage my car gos in at the end of next week finaly got all my parts :) i was wounder about what u said do u think every time u get a died battary or need to unplug it u will lose your tune i hate to keep blowing a few hundred everytime i need a jump or something

To be on the safe side ,unhook your battery right before tuning to reset the ECU.All the anwsers seem to point to this..

Ill 4 sure let you know what we find bud, If the theory is in fact correct.It seems like the ECU should be reset right before you begin tuning the e-manage to clear out all the trims.And as a extra precation maybe use some sort of backup power supply to keep enough volts to the ecu in the event of a need to swap out a batt..Theres a cigerette lighter one that one could plug in as a backup power source just for a battery swap(wont really help on a dead batt. like left lights on)

the ultimate goal would be to tune the emanage to with no trims in the ecu,therefor your map is correct dead battery or not.

how do you get it to stay that way??

Good question.,but seems like a pipe dream at this point..The only true solution is standalone..
Ever after clearing the ecu-its gonna continue to log trims..I guess my thought was the closest thing to idle is to clear the ecu and tune right then.That way if anything happens to battery you at least have a map that was made with no or minimal trims,therefor you can reload that map back into the emanage after clearing the ecu again and all should be fine *in theory* lol

Get a standalone :D

seriously though - before you install your kit you check and make sure the fuel trims are in low single digits on the stock system. If they aren't you figure out whats wrong before you install the kit. Once the kit is on you just tune it to bring the fuel trims to 0 or as close to it as possible. If your tune is food with 0 fuel trim it will be good after battery reset as well.

I guess everyone just wants the easy route.
DING DING DING!!!

All that would be required to make a Celica PFC work on another platform (assuming manual trans and cable throttle) would be buying the Celica ECM plugs from Toyota, backing out all the pins from your existing connectors and swapping them over to the correct spots on the Celica plugs.

i have a 04 and as of now i only realy got the money to install and tune the emanage and kit school books are killing me lol

Sounds like you should be holding off on forced induction till you have more money and a beater.
