walkerstrider Posted September 9, 2015 Share Posted September 9, 2015 Just finishing off my na-t build, wired up the emanage blue as per instructions but when I turn the ignition on the left light flashes constantly and the right light stays on. Can't seem to find any info on what the cause is. Any ideas?? Quote Link to comment Share on other sites More sharing options...
Josh42 Posted September 9, 2015 Share Posted September 9, 2015 Do you have an aftermarket Immobiliser or alarm fitted? Sounds like it could be interfering? Are you getting the sound of the fuel pump priming? Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 9, 2015 Author Share Posted September 9, 2015 I do have an alarm and immobiliser fitted, don't think I'm getting fuel pump sound, what should I be listening for? It will turn over too but won't start. Quote Link to comment Share on other sites More sharing options...
Josh42 Posted September 9, 2015 Share Posted September 9, 2015 What fuel pump do you have fitted? When the ignition is turned to position 2 and the car is unimmobilised you should hear the fuel pump prime. Not sure it will be immobiliser though if it's cranking over. Have you checked all the earth points including the stock ECU? Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 9, 2015 Author Share Posted September 9, 2015 Can't hear the fuel pump Just checked. I'll have to check earth's in the morning as it's too dark now. - - - Updated - - - It's a standard fuel pump Quote Link to comment Share on other sites More sharing options...
Josh42 Posted September 9, 2015 Share Posted September 9, 2015 You should hear the pump prime mate, but it wouldn't be as prominent as an aftermarket pump. Quote Link to comment Share on other sites More sharing options...

walkerstrider Posted September 9, 2015 Author Share Posted September 9, 2015 I have had to change distributor, could it be anything to do with timing? I set it with rotor touching number one on cap at tdc. Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 10, 2015 Author Share Posted September 10, 2015 It's started at last but still have the lights on emanage as well as engine light on dash, any ideas? Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 10, 2015 Author Share Posted September 10, 2015 Car is now missing like hell, reset the timing no difference, now when I turn the car off but flick ignition back on, light on right side stays lot and the left one flashes red.

berg Posted September 10, 2015 Share Posted September 10, 2015 I had the same problem on my emanage ultimate on my old na-t Ran like an absolute dog, timing etc was fine 2 of the wires (map sensor, temp sensor) were wired wrong The instructions i had were incorrect which made the 2 wires the wrong way round I would double check all wires match the diagram and even try and source another diagram online, thats what i done Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 10, 2015 Author Share Posted September 10, 2015 Cheers bud I'll try swapping them round. Irrelevant at the min, got a bloody oil leak from return flange on sump! - - - Updated - - - Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 21, 2015 Author Share Posted September 21, 2015 Help still needed, been to mappers today but couldn't get map done as it's seriously over fueling! Got error code 31 come up,also there's no voltage on the air flow green wire! Air flow white wire shows 3.5 volts. Any ideas? I'm at a loss!!

berg Posted September 21, 2015 Share Posted September 21, 2015 Using the Greddy map sensor? Have you checked the wiring as the symptons sounds map sensor/map sensor wiring related Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted September 21, 2015 Author Share Posted September 21, 2015 Yeah I've tried swapping wires and all sorts, so I disconnected emanage and ran it with stock map sensor running the vacuum straight off inlet manifold, it was coming off the branch. and it seems to be OK, no more black smoke but still runs extremely rough.

walkerstrider Posted September 26, 2015 Author Share Posted September 26, 2015 (edited) Any help appreciated. I've just fitted an Afr wideband gauge to see just how rich I was running. With the emanage hooked up it runs at 9.6 at idle and really runs terrible up to about 3000 revs With the stock ecu it runs at around 14.5 at idle. And runs so much smoother although it is a little lumpy at tickover. And with the emanage hooked up the engine light stays on, with the stock ecu it doesn't. Would this be down the a map already on the emanage or something else as I'm a little stuck and need it back on the road asap! Thanks in advance.

Tricky-Ricky Posted September 26, 2015 Share Posted September 26, 2015 Its obviously down to the emanage, but I would suspect something is not set up or connected right with that AFR reading, if it was purely the emanage map the std ECU would be fighting it a bit more than that, as the emanage is not able to keep closed loop AFRs that low, check the MAF and MAP connection's.

Hi walkerstrider, I wish i could help you, but this area of the Supras to me is the most complicated and most important on the car, i just had an NA/T carried out by a experienced professional, but for the mapping and importance of getting it spot on, especially for mpg and performance, is why i did not fit the kit DIY. I would consult a pro and get it sorted as even if you do get it running seemingly ok, you may still have mpg issues or running lean which could damage your engine. Good luck anyway.

Ian C Posted October 6, 2015 Share Posted October 6, 2015 It'll probably be barely running at that AFR, far too rich. If you take a data log of it, recording everything, and post it up here, it'll help with diagnosis. See what the E-Manage is seeing and what it thinks it should do with it.

Yeah it virtually stalls with the emanage hooked up. I don't think it's reading airflow as I'm getting very low voltage on the output wire but 3.5 on input. On the emanage it reads. 1 input voltage and 0 output! Something strange though, if I disconnect and connect volt meter to pin 62 on ecu it reads 4.5 volts? Surely this should read 0 volts until it's connected. I'm lost! Double checked this is correct wire for ar connection. Seems to be according to every shematic I've seen. Runs fine if I disconnect ar wire but obviously I get the error code on emanage. I get this even with it hooked up tho. Maybe it's the wrong wire but don't know what other wire to try.

trebor69 Posted October 10, 2015 Share Posted October 10, 2015 I'm afraid I can be of no help at all other than to let you know that I have an Emanage blue unit here......I don't suppose it could be anything to do with that could it? You are more than welcome to try it if you like. Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted October 10, 2015 Author Share Posted October 10, 2015 Cheers rob are you in tomorrow afternoon? I'll find that dipstick out. It's looking like it may be the emanage. Quote Link to comment Share on other sites More sharing options...
walkerstrider Posted October 12, 2015 Author Share Posted October 12, 2015 OK so I've tried a different emanage with a safe map on and still exactly the same problem! I've also tried different jumper settings rotary switch settings. Nothing seems to change anything. The airflow is connected to pin 62 on the ecu. White going to sensor and green going to ecu. If I leave the emanage connected apart from airflow wire it runs fine. I am completely lost!! Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted October 12, 2015 Share Posted October 12, 2015 So its connected properly, the jumpers are set correctly and the rotary switches have been tried in different positions, have you tried adjusting the overall fuel trim setting? given that you have tried another unit and disconnecting the emanage and allowing the std airflow to scale things works fine. This would suggest that its down to the emanage settings. As I have never owned an N/A can you tell me the airflow setup IE MAP MAF or both?

Literally just exported a safe map which up until the higher rev range all values are zeroed which I understand means the stock ecu settings will apply. It works on the map sensor but there is also a maf probe which pushes in just behind air intake. I changed this for a different unit also but no difference.
