ballsdeep Posted March 18, 2015 Author Share Posted March 18, 2015 Beep testing the wires might not be good enough mate , test them in ohms you would want them all under 0.9 ohms Well had 2mins this morning and checked ohms, both igt and igf wires showing 0.5/6 from ecu loom end to igniter plug end. time to beg borrow steal a third igniter and distributor Quote Link to comment Share on other sites More sharing options...
ballsdeep Posted March 21, 2015 Author Share Posted March 21, 2015 Well I give up!! After swapping 3 igniters 3 coils 2 ecu's and a distributor I'm still getting no spark from the coil so im throwing in the towel and handing it over to a auto electrician! Il post up his results Quote Link to comment Share on other sites More sharing options...
ballsdeep Posted March 22, 2015 Author Share Posted March 22, 2015 I said I'd gave up but couldn't resist having one last check and kind of stumbled across something. I decided to remove the emu and patch extension harness and just see if I was getting a spark with it running off the stock ecu, result nice strong spark coming from the king lead so I must be something to do with the e-manage ultimate or harness but checking the emu Jumper settings I have jp8 set to 1-2 I believe this to be ignition 8v but reading an old thread it should be 12v (2-3) is this correct?

Chris Wilson Posted March 22, 2015 Share Posted March 22, 2015 Sorry, I had no idea you had this "thing" installed, my first advice would have been to go back to base and bypass anything that "interfered" with the stock ecu signals. Quote Link to comment Share on other sites More sharing options...
ballsdeep Posted March 22, 2015 Author Share Posted March 22, 2015 (edited) Not to worry chris I'm just gratefull of all the help! I now have an endless supply of igniters, coils and ecu's Am I right in thinking the NA ignition system is 12v and if so would this be the reason why it's not sparking because I have the emu Jp8 set as 8v? (Iv had it set like this since day1 though) Edited March 22, 2015 by ballsdeep (see edit history) Quote Link to comment Share on other sites More sharing options...
ballsdeep Posted March 23, 2015 Author Share Posted March 23, 2015 Clutching a straws now so changed the jp8 setting to 2-3 and re-soldered the ignition control wires but I'm still not getting a spark! Anyone experienced faults with the e-manage ultimate or has any advise on which wires control spark? Quote Link to comment Share on other sites More sharing options...
T2 MSW Posted March 23, 2015 Share Posted March 23, 2015 Id be looking to get someone that knows the emanage in detail to check out the ECU. Certainly would not be changing jumpers that effect voltage output as if its not correct could blow something. If you get a spark with just the Stock ECU then that MAY be a way to move the car. I don't know enough about your setup to make recommendations but if you have a stock engine and its just turbo changes you have made then the car can be moved about using just the stock ECU.

mellonman Posted March 23, 2015 Share Posted March 23, 2015 If it did work , Then a jumper setting is not going to just change on its own, sounds like your emange is shot , if you have the software down load your map from it , if you dont then get the software to down load your map , get another emanage up load you map and try it Quote Link to comment Share on other sites More sharing options...

I don't know enough about your setup to make recommendations but if you have a stock engine and its just turbo changes you have made then the car can be moved about using just the stock ECU. Problem is I have 550 injectors in so wouldn't be able to drive the car anywhere with just the stock ecu. If it did work , Then a jumper setting is not going to just change on its own, sounds like your emange is shot , if you have the software down load your map from it , if you dont then get the software to down load your map , get another emanage up load you map and try it I'm leaning towards the emu being shot too! But don't know anyone who can test them and nobody's going to borrow me one to try! Might see if Nodalmighty can download the map for me?

Chris Wilson Posted March 23, 2015 Share Posted March 23, 2015 As mellonman rightly says, jumper settings don't change themselves, and it's VERY rare for an EPROM to lose settings to the extent some things work and some things don't. I would need to see a manual and schematic for the EMU, and some superb high resolution photos of what it's like inside to attempt to make a judgement as to whether it's likely to be an EMU issue (and I think it probably is from what you post) and whether it's likely to be repairable at the component level. I REALLY REALLY *REALLY* think that if it's knackered you should save for something better like a LINK or similar. Quote Link to comment Share on other sites More sharing options...
T2 MSW Posted March 23, 2015 Share Posted March 23, 2015 (edited) Right yep can't run it on the stock ECU then. Im sure there was an E-Manage in the for sale section not so long ago for cheap.

Tricky-Ricky Posted March 23, 2015 Share Posted March 23, 2015 I'm confused, and without having to go through the whole thread, have you reverted back to the original connection for the distributer to eliminate the EMU? Unless I am mistaken when using the EMU to adjust the timing when using a distributer its only two wires that's connected as its a global timing adjust? so easy to swap back. Is the EMU showing any fault lights? jumper 8 wont have any detrimental effect as AFAIK its not applicable to distributer equipped vehicles, and only applies to individual coil on plug applications.

That's correct mate I removed the patch extension and emu just to see if it would spark, (king lead disconnected) since I'd replaced everything else to do with the ignition side and had no luck it was the only thing left to check! Iv been lucky to cross paths with lyndon (Nodalmighty) and he's very kindly offered to take a look at the emu for me so il be dropping it off with him tomorrow, if it is screwed then I have 3 options 1 - strip for parts and move away from supra's for a while 2 - find another emu 3 - look for a alternative ecu maybe standalone (this being the most expensive root which I'm not sure I would like to commit too) Out of curiosity if I was to put the 330 injectors back in would I be able to use the car daily but off boost or would this be a bad idea? So stock compression, injectors and ecu. But turbo'd and TT manifold Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 23, 2015 Share Posted March 23, 2015 Are they the std injectors? not sure which the N/A runs, you could remove the waste gate spring. or wire it open, that way its not going to boost, but it will be rather noisy.

ballsdeep Posted March 26, 2015 Author Share Posted March 26, 2015 Yes the 330's are stock NA injectors, I'm struggling to cope without my car so if it's safe enough to drive like that I might swap out the injectors and just cruise around off boost? That being said the 330's have not seen fuel in a long time so there's no saying they will be any good? Quote Link to comment Share on other sites More sharing options...
ballsdeep Posted April 13, 2015 Author Share Posted April 13, 2015 Just to end this thread and my misery I can happily say SHE'S ALLLIIIVEEE :d Turned out to be the e-manage ultimate ignition control side of things that packed in! So we fitted the brand new EMU and the brilliant Nodalmighty set about mapping it in the rain! after slightly loosing traction on the motorway in between two cars we managed to get most of it done, I'm thrilled and can't be happier!

T2 MSW Posted April 14, 2015 Share Posted April 14, 2015 glad its sorted. Not good that a fundamental component of the ECU failed though. Lyndon going to look at the hardware and see what went wrong or have you just binned it? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 14, 2015 Share Posted April 14, 2015 Coil drivers usually die because they are seeing either the wrong impedance (load) or the dwell time is excessive. Or they are plain marginal.... Quote Link to comment Share on other sites More sharing options...

Thanks, it's for sale, http://www.mkivsupra.net/vbb/showthread.php?321263-E-manage-ultimate-partial-faulty lyndon said it can still be useful as a fuel controller or even repaired? Coil drivers usually die because they are seeing either the wrong impedance (load) or the dwell time is excessive. Or they are plain marginal.... This means nothing to me! You might as well be talking to my 2yr old but I hope to god the same thing doesn't happen to my shiney new emu (3days and counting trouble free) Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted April 15, 2015 Share Posted April 15, 2015 It's probably a driver transistor that's failed, it may even be repairable. I would have a look at it if you are in no hurry. Quote Link to comment Share on other sites More sharing options...
