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.

    • There's plenty of OEM steering arms that are bolted on. Not in the same fashion/orientation as that one, to be sure, but still. Examples of what I'm thinking of would use holes like the ones that have the downward facing studs on the GTR uprights (down the bottom end, under the driveshaft opening, near the lower balljoint) and bolt a steering arm on using only 2 bolts that would be somewhat similarly in shear as these you're complainig about. I reckon old Holdens did that, and I've never seen a broken one of those.
    • Let's be honest, most of the people designing parts like the above, aren't engineers. Sometimes they come from disciplines that gives them more qualitative feel for design than quantitive, however, plenty of them have just picked up a license to Fusion and started making things. And that's the honest part about the majority of these guys making parts like that, they don't have huge R&D teams and heaps of time or experience working out the numbers on it. Shit, most smaller teams that do have real engineers still roll with "yeah, it should be okay, and does the job, let's make them and just see"...   The smaller guys like KiwiCNC, aren't the likes of Bosch etc with proper engineering procedures, and oversights, and sign off. As such, it's why they can produce a product to market a lot quicker, but it always comes back to, question it all.   I'm still not a fan of that bolt on piece. Why not just machine it all in one go? With the right design it's possible. The only reason I can see is if they want different heights/length for the tie rod to bolt to. And if they have the cncs themselves,they can easily offer that exact feature, and just machine it all in one go.

    • This is how I last did this when I had a master cylinder fail and introduce air. Bleed before first stage, go oh shit through first stage, bleed at end of first stage, go oh shit through second stage, bleed at end of second stage, go oh shit through third stage, bleed at end of third stage, go oh shit through fourth stage, bleed at lunch, go oh shit through fifth stage, bleed at end of fifth stage, go oh shit through sixth stage....you get the idea. It did come good in the end. My Topdon scan tool can bleed the HY51 and V37, but it doesn't have a consult connector and I don't have an R34 to check that on. I think finding a tool in an Australian workshop other than Nissan that can bleed an R34 will be like rocking horse poo. No way will a generic ODB tool do it.
    • Hmm. Perhaps not the same engineers. The OE Nissan engineers did not forsee a future with spacers pushing the tie rod force application further away from the steering arm and creating that torque. The failures are happening since the advent of those things, and some 30 years after they designed the uprights. So latent casting deficiencies, 30+ yrs of wear and tear, + unexpected usage could quite easily = unforeseen failure. Meanwhile, the engineers who are designing the billet CNC or fabricated uprights are also designing, for the same parts makers, the correction tie rod ends. And they are designing and building these with motorsport (or, at the very least, the meth addled antics of drifters) in mind. So I would hope (in fact, I would expect) that their design work included the offset of that steering force. Doesn't mean that it is not totally valid to ask the question of them, before committing $$.
