@Adamw yes I have tried the test function, but doesnt work. I am in Ireland so should be around 10 degrees in the evening time. Will recheck all this eve. @DerekAE86 I didnt have a pinout for the honda cbr tps, I may have my wires mixed. Will check that this evening. I can only assume but maybe I have 5v on the ground pin which is spiking my iat & ect.

@DerekAE86 sorry i thought it was something completely different, i have attached it now. Are you able to see why my fan on aux2 isnt working and oil pressure not working on it? 04.07 Micra.pclx also to not my iat temps and ect temps. engine is cold and reading 30 degrees celcius. Could this just be the two pin plugs wired the wrong way around?

@essb00 probably a silly question but how do I do that? another thing I’ve noticed is, once trigger calibration is done the car sometimes revs up to 3500 rpm until I turn it off. Any ideas? thanks

@Adamw @DerekAE86 I have attached a log file. Can you give me some feedback/info on my trigger calibration. The car will run at 6 degree offset or -354. At 6 it is slightly erratic whereas -354 it is bang on 10 degrees at crank. Car dies every time I add some throttle. There is also a very strong smell of fuel. Do I need to set injection up as I only have crank trigger, tps & iat? As you can see when idling injection time is 400 btdc, surely this is wrong no? I checked the wiring to oil pressure, if I earth multimeter at engine I get 4.97v at 5v pin, if I earth it at 0v pin I get 0.3v , nothing at signal wire. Any ideas? Battery voltage issue is due to a faulty alternator which I will be replacing. any updates pointers would be great, thanks Log 1.llgx

@DerekAE86 that’s the exact wiring I have , I was just wondering should show continuity to block. Will post results of multimeter this eve. @Adamw will be uploading this tonight, thanks

@DerekAE86 the weird thing is it was working, as you can see in photo attached, I previously mentioned it was reading 30 psi/2 bar which is perfect for the micra engine. But now there is an issue. Will have to look further into it this eve. Should I be getting continuity through the wiring on 0v side to engine block ?

@essb00 I get you now. I had it at 10 btdc and offset 6 degree to have 10 degrees on crank and 10degree on pc. It ran using those figures. @DerekAE86 thanks will update tonight with more work carried out. @Adamw is it possible oil pressure sensor has changed settings snone where since I’ve uploaded a new map? Although I have configured it to analog volt 2. Very confused as it was working. thanks

@DerekAE86 the standard engine runs 15 +/- 2 degree BTDC. Is there a reason to change to 10 ? Just curious. Thanks

@DerekAE86 is this trigger calibrate ? I have it set at 10 degree btdc and 6 degree offset

@Adamw the oil pressure sensor was working perfectly yesterday and now not. It’s a link 10bar. I will attach a log file tomorrow and see what has happened. In better news the engine started and idled, although rough as It needs adjusting on the timing side. when the car is idling what ignition angle should I be seeing 10 degree btdc?

@Adamw Hi Adam, didn’t get much further this evening as I now have an oil pressure issue , no fault stored but since firmware update its reading 143 psi ? Is there something I need to change in settings ? See attached also when wiring wasted spark with k20 coils do I need an ignition or module inbetween or just splice ign 4 into ign1 and ign 3 into ign2 and set firing order to 1212 or still 1342. thanks

Sorry for annoying you @Adamw but we are getting somewhere. So the crank is now picking up around 2-300 rpm , injector test works on all injectors as does ignition coils. I still need to rewire the coils. IAT and ECT are reading correct, oil pressure is getting up to 33psi on crank (should rise when idling) and TPS and fuel pump is working as should. So once I wire the ign coils correctly all that is left is to set the timing. I’ve turned it over and it gives a splutter so we are on the right track. Need to check if my trigger lamp is working as didn’t seem to flash when connect to the car , will try on another car tomorrow. I’ve 3 questions you may be able to help on. when I crank the car a message pops up about a new ecu has been found with a different map ? I have a red error fault for aux 2 for engine fan? Even with all the wires disconnected it is red ? I’ve told the ecu that the fan is aux 2 and still the fault. and see attached photo about btdc if you can give me any direction to go with setting it up. (Please note no lambda fitted yet) thanks so much

@Adamw the link you attached for 4age doesn’t seem to work? I found one you sent somebody else a while ago but I think it’s set up for map sensor? I wired ignition powder to ecu relay and all working perfect now and can see sensors reading. Just need to calibrate crank and should be good for a start. is there something I need to do to tell I’m starting for example to prime fuel pump? I can activate it through test function thanks

Thanks guys for the responses, will be looking at the car this evening and see how I get on. @Adamw do i need to rewire the coils or just set it to wasted spark ? also would anyone know k20 coil pin out and cbr tps pin out ? Just to be sure I’m right. thanks

@Adamw sorry it was a typo error it has a 36-1 trigger wheel. I only got the wiring finished yesterday and spent an hour messing around. Will check the acc or ignition feed to ecu. So the ecu doesn’t need a second power to keep it powered on cranking ? also how do I set base timing through the ecu? I have a trigger lamp but as car is coil pack now and not ht lead how do I set that? also would you know correct pin out for k20 coilpacks to check if I have it wired correctly thanks for attaching that. I will give it a go tomorrow evening.

Yes I have a battery charger on the battery reading 100% and new battery. I’m just conscious that I’ve wired my 14+ from a relay triggered by ignition switch which turns off when key is off. Should the ecu be getting battery voltage instead ? Also , the car only has a crank sensor as no cam sensor. The crank sensor has also been added to the car so I need to tell the ecu where the offset of sensor is for tdc ?

Hi Guys, I’ve just finished my wiring loom on my 1997 Nissan Micra with a Link AtomG4X ecu. I have the ecu connected to pc but I have two issues. 1. Every time I crank the car it disconnects from the ecu from pc? 2. Theres no base map in files for a Nissan Micra so where do I start about getting it started or a base map? spec is 4 cylinder NA firing order 1342 33-1 trigger wheel crank honda k20 coilpacks link can lambda honda cbr itbs with tps & injectors link iat link oil pressure sensor nissan coolant temp sensor Thanks in advance

Thank you so much

Can this model take one or do I just use a normal lambda sensor ? thanks

Hi All, Starting to wire up my g4x and will be running a link can lambda. On my pin out (Loom A) I don’t have a can high or can low pin labelled. My question is , can this be used in aux 7&8 ?

Thank you

Hi Adam, Would this kit be the right one to work with atom g4x. Thanks

Hey guys, Just about to start into my first wiring harness for a NA 4 cylinder. I’ve got a link atom g4x ecu. Do i need a wideband? If so what else do I need to make it work, can system etc.. Thanks

@Adamw many thanks for the replies and help much appreciated. as for your questions yes the dash has a coolant gauge and oil pressure light (not pressure sensor or gauge ) i will probably look to buy an oil pressure gauge so will be using a 3 pin universal oil pressure switch then . The guy who will be mapping the car said I just need to upgrade from 3 to 4 wire lambda sensor ? And with the Tacho i don’t know if it’s a high level type will be a case of trial and error . Also these engines have a coolant switch on the head for the fan , will I need this or will ecu activate the fan through my aux output Also do you know what sensors etc should be used for digital input cheers

Hi guys Ive got a 1997 Nissan micra k11 which i have a link g4x atom ecu got for it(34 pin plug), currently making my wiring loom and have a few questions i hope some of you can help with, Q1. Im going to be using my factory cluster (rev counter model) the only sensors i need on it are oil pressure, coolant temp, rev counter. How do i go about wiring from the ecu to the cluster ? do i just feed off the sensor wires going back to ecu? Q2.Ive upgraded my 02 sensor to a 4 wire universal, where do these 4 wires go on the ecu? Q3. The micra originally had a distributor but i am running a 36-1 trigger wheel and going yaris coil on plug conversion, the original rev counter was wired through the dizzy , will the ecu know the revs through the crank sensor and i can wire to rev counter through aux 3 ? Q4. The yaris has 4 pin plugs , obviously the ign 1-4 go to one plug on each but where do the other 3 come from ? Q5. My original oil pressure sensor is a 1 wire sensor and earthed through block , will i need to upgrade to a generic 3 pin sensor thanks in advance
