Emanage Ultimate Problems

Hi all,

I am having problems with my emanage ultimate. Went to have a dyno tune yesterday and they weren't able to connect to it because they are running windows 7 on their laptops and the emanage requires XP or 98. So i got it home and had a go connecting on an old laptop. Still had problems connecting at first but managed to connect after returning the e-manage to an older firmware version.

Now however the car is running like shit, misfiring and struggling to idle correctly. Obviously something has changed with the emanage settings after i changed the firmware version to do this as the car was in top shape coming back from the tuner's. I cant figure out what though as i dont know what the settings used to be and it is pretty much undriveable now!

also is there a way to disconnect the emanage easily so i can just run off the stock ecu? at least will be able to get it back to the workshop that way and they can have a look at it.

Any help would be much appreciated

it has a proper harness if thats what you mean, i didnt install it myself but its been in the car since i bought it over a year ago with no dramas. is there any reason why going back to an older firmware version would stuff up the settings on it?

Just unplug the harness and plug the standardard eve back in as normal.

Pretty sure I had to reload my maps back in after a firmware update. So maybe a bug in the software?

ok will give that a shot in the morning. do you know what settings i could try changing to get rid of the misfire? the maps are still as they were before

Have you downloaded the update? V2.2. http://www.greddy.co...upport/e-manage

It would need the current version loaded. Make sure you have a copy of the map saved.

was going to try that too, except that it already had the latest version of firmware on it when it couldnt communicate, thats why i reloaded an older firmware version back on which allowed it to communicate but screwed the settings

i should probably mention this is also because i dont have the cd, had to download the software off the net and apparently they struggle to communicate when the firmware on the emu doesnt match the firmware on the laptop. hence why i tried the older version

Surely theres someone around with the disk nearby, where are you located? Fresh install, update from greddy and then update the unit.

update: downloaded and updated the software thismorning, successfully updated the firmware and was able to communicate with unit still. the misfire and bad idle problem still remained so had a look at the ignition wiring (which was coming up with errors) and it was out of sequence (1,2,3,4,5,6 instead of 1,5,3,6,2,4). Disconnected the battery and rewired these to the installation instructions and tried starting the car, which did not like it at all! The original sequence was correct even though it was different to the instructions i do not know why! it does say on my ecu that it is a reconditioned one so maybe the ignition wires have changed spots im not sure. Anyway i rewired it back to how it was before and it started fine again, but stil idling bad and misfiring. Ended up giving up and disconected the laptop, turned the car off. Decided to take it for a test drive to see if i'd be able to get it down to the workshop tomorrow and it doesnt seem to be misfiring or idling bad anymore! Dont want to speak to soon tho hopefully it stays good until i get it to the workshop, no idea what would have changed to make it better again!

There were some issues with some of the earlier units regarding the igniter signal I seem to remember, it could be related to that, otherwise I have had issues sometimes when I dont write the data to the emanage after changes on the fly, and occasionally where it wont start after a tune for some reason, it always comes good though.

See how it goes after a few starts. Hopefully its fine now.

i reckon the ignitor chip is damaged, the early ones were to close to the case slides and the board would be damaged upon removal and install. What letter is on the main board? look inside there will be a letter A B C D or later ones are E

e-manages can fickle at the best of times and unfortunately due to the crazy factory R33 (most other cars dont have a timing map that goes from 9-18-5 in one load line) mapping the emanage is not the best solution even if it all runs sweet. We do alot of them and most we've been able to extract with one is around 410rwkw but R33 factory ecu makes it hard to tune nicely... its adequate but far from nice.

      r34's love to squeal

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
