hodge Posted March 30, 2009 Share Posted March 30, 2009 Hi Guys. Ive got a few problems with me EMU setup, could any of you shed some light on the subject please. The car seems to be coming up with a error code 14 (ignition fault). as soon as i crank it. Ive checked all the conectionson the field harness and there fine. Ive even taken the EMU out and started it with the stock ECU and it started with no error codes. I did a comparision with the main unit and it came up with 3 parameter errors. Channel Settings Front pannel Ignition. Im at a total loss now as ive tried everything i can think of. so its over to you EMU experts if you dont mind. OH and i should add I got the map from Ian C, and its for a Siingle with 800cc hi-impetance injectors, veilside intake and 90mm throttle body. Any pointers or advice would be great here. cheers in advance john Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted March 30, 2009 Share Posted March 30, 2009 Couple of things to check. 1. That the wiring is correct i.e IGT Wires from Stock ecu goes to Ignition Channel Inputs, Then Ignition Channel outputs to Stock Loom (ignitor)... 2. That you have wired up the Ignition Inputs to match the Firing Order. Ie IGT1 - ICI1 IGT2 - ICI5 IGT3 - ICI3 ETC 3. That you have only Tapped into the NE and G1 wires not cut off the feed to the stock ecu. 4. That jumper 7 is set to 1-2, jumper 8 is set to 2-3 and Jumper 15 is set to 1-2 Ryan Quote Link to comment Share on other sites More sharing options...
hodge Posted March 30, 2009 Author Share Posted March 30, 2009 Cheers for the reply Ryan. All the soldering was already done when I bought the unit. It had previously been running on a BPU car with 550cc injectors. I bought if from Flukey lukey who bought it from Kranz. heres a list of the jumper settings I have. 1, open 2, open 3, open 4, open 5, open 6, open 7, 1-2 8, 2-3 9, open 10, 1-2 11, open 12, open 13, open 14, 1-2 15, 1-2 16, open 17, open 18, open 19, 1-2 20, 1-2 It has the injector 2 adaptor harness thingy fitted in also.

hodge Posted March 30, 2009 Author Share Posted March 30, 2009 well after spending all day messing around with it (well as well as cleaning my sons sick up) im starting to think its a settings/jumper error. The car will fire but slowly just dies after a second or 2. if I apply the throttle it cuts out instantly. After a few of these attempts the active LED flashes green indicating fouled plugs. Odviously this will be due to overfueling /flooding. Could someone please give me a cross reference for the jumper settings and I can start there. Many thanks Quote Link to comment Share on other sites More sharing options...

Your jumper setting look OK to me, can you do some screen shots of your parameter setting? if it been running on another Supra then the wiring must be OK, so i suspect a settings problem.

hodge Posted March 30, 2009 Author Share Posted March 30, 2009 Cheers for the reply fella. ill sort that now and stick some pics up. Many thanks. Quote Link to comment Share on other sites More sharing options...
hodge Posted March 30, 2009 Author Share Posted March 30, 2009 Ok after a bit of a fiddle ive got some screen shots but yet there rubbish. The comparision errors were in the perameter settings. So ive taken pics of the ones that were highlighted. Ignition Front panel channel settings Anything you can suggest would be a help. Cheers.

Tricky-Ricky Posted March 30, 2009 Share Posted March 30, 2009 Bit blurry, but anyway what i have noticed is that you don't have any maps selected in your dip switches, and although it shouldn't stop start up, it won't help when you want to use the maps, you need to at least select an injector map and a timing map, and make sure you flip the corresponding switches down. What i really need to see are, injector settings, vehicle settings, front panel and throttle setting, you have done the throttle setup procedure i take it?

hodge Posted March 30, 2009 Author Share Posted March 30, 2009 I set the throttle up the same as I did with me e01. Pushed the throttle to the floor and them pressed the apply button. Is this correct. Does it matter what channel of dip switch i use for the injector and timing. The base map was done by Ian C so i am confident thats ok. Ill get the injector, throttle and vehicle settings pages up. Well thats if you can see them. Quote Link to comment Share on other sites More sharing options...
jevansio Posted March 30, 2009 Share Posted March 30, 2009 John, to get better pics, with the window open (and with focus) hold Alt & hit the Print Screen key (near scroll lock along top). Then open something like MS Paint (or equivalent on XP/Vista) & from the Edit menu choose Paste or Paste As New Image, then save it for use on here as per a normal image Quote Link to comment Share on other sites More sharing options...

As long as you have the 0 %with a low voltage besides it and 100% with a high it should be fine, check it still there next time you open it up, It doesn't matter which of the four channels you use, as long as the corresponding switch is turned on. If Ian sent you the complete set up and not just the maps then I'm sure it will be right.

Tricky-Ricky Posted March 30, 2009 Share Posted March 30, 2009 OK first off you need to input your injector sizes (or has Ian done you an airflow map?) Second you need to select your injection map1 and your ignition map1 in the dip switches. The rest looks OK, what about the throttle setting? Also can you open the water temp adjust map so i can see?

hodge Posted March 30, 2009 Author Share Posted March 30, 2009 (edited) Yeah there is an airflow map see below. So if I just set dip switches 1 and 2 to on this should be ok??? Edited March 31, 2009 by hodge (see edit history) Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 30, 2009 Share Posted March 30, 2009 Thought so Ian compensates for injector size via airflow map, yes you need to turn on the injector and ignition maps, but AFAICS there is no reason that it won't start, are you sure there is no problems with the wiring? have you made sure that all the multi plugs and ECU plugs are connected firmly? Can you try taking a log of an attempted start? Quote Link to comment Share on other sites More sharing options...
hodge Posted March 30, 2009 Author Share Posted March 30, 2009 ill give that a go tomorrow when i finish work. Like i said when i did a comparison it came up with 3 perameter errors. Ignition Front panel Chanel settings. There must be a discrepency in my settings and ians map. Just something that ive missed. I think i need to find these errors and sort this error code 14 as it doesnt apear with the emu out the equation and the car starts no probs.

Ian C Posted March 31, 2009 Share Posted March 31, 2009 You don't need to assign a map to the DIP switches to actually enable them. I've done a few without assigning anything in the DIP switch settings, and they all worked And, if you look at the options available in the DIP switch assignment, there is boost cut setting, water temp correction, intake temp correction... All sorts of ancillary crap. You can just assign maps in there to switch between on the fly if you have some esoteric need to, it's not essential. I leave the injector compensation bit well alone as it shafts the datalogging values and causes more trouble than it's worth in the tuning process - you know where you are with a table of values Also, I've only ever had to adjust the injector lag timing once on some oddball injectors. I've PMd Hodge about JP10 and JP14, they aren't set right in my opinion, although I'm not convinced it'd stop the car from starting. If you are getting comparison errors between EMU and what the laptop software says you need to try exporting to the main unit again. It's not a UK spec is it? They don't like the ignition system being messed with. -Ian PS uploading the map I sent you will give you everything you need settings-wise apart from the throttle positions, they'll be set to my car Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 31, 2009 Share Posted March 31, 2009 I know you like to use the airflow settings map for the injector correction, but doesn't altering this before the std ECU cause ignition timing adjustments in the std ECU ? However i'm not sure if the global injector setting achieves just the same result anyway, but hopefully without the timing adjustments:) Interesting point on the panel dip switches, i have never tried turning them off completely,i have 1 set as injector map and 2 set as timing. The guys from OZ and NZ seem to advocate using injector maps 1 & 2 together to create an expanded map with more scale, been meaning to try this. I think JP10 is just an option for either being able to use the Skyline twin AFMs or the Vtec, cant see it being a problem as one wire is not connected anyway? JP14 is just if you want to use an input for knock or water temp, so the option is for a normal input or pull up depending on wiring, so i can't see any problem with either that would have any impact on starting. Still sounds like a wiring issue to me. Quote Link to comment Share on other sites More sharing options...
hodge Posted April 1, 2009 Author Share Posted April 1, 2009 the unit was running in a supra before i bought it thats why i didnt think it was a wiring fault. Just a point of interest does my laptop req any software updated for the support tool my mate mentioned something like firmwire or something like that. Also can the emu be formatted back to its factory setting. Just trying to cover every avenue really. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 1, 2009 Share Posted April 1, 2009 There are a series of updates for the software, unfortunately they where all hosted by Mhodparts, which is no longer running, greddy have the latest, not sure if they have an archive, The latest version is 2.20 1.13 but as long as the laptop and the unit are running the same its not a problem. Not sure about the backward software possibility, don't really see the point as more functions where added and bugs fixed with each update. Like i said have you double checked the multi plugs etc?

hodge Posted April 1, 2009 Author Share Posted April 1, 2009 now i think you may have hit something there. The emu was 2nd hand but i just put the support tool on the laptop without updates. Ill update it today when i get up and see if any miracles occour. If not then its harness out and inspected. Quote Link to comment Share on other sites More sharing options...
