    apologies for very late reply ! but i have since gone for a higher spec ecu (ms3 pro ultimate) full engine build... box build as well still on with this rpm issue is it simple pulse or progressive voltage or proprietary signal ?
  2. centoproject
    the system is also faulting before ecu removal mate can you post a link ?
  3. centoproject
    right guys I'm back ! car will be coming back from tuner quite soon so i want to prep ideas to fix this abs issue summary time... s1 stagea now with an aftermarket ecu for the engine side of things from what i understand all i need from the engine side to the attessa/abs aspect of things is a tsp signal wire ? as said before even when stock the abs module in the back would not flash regardless of what i had tried attessa side i have for now replaced with custom hydraulic system to mechanically lock the system for the dyno i have scoured the internet for ages on this topic but no real conclusion for the s1 stag any new data arisen since i last posted ? would a faulty speed sensor throw any codes/flash ?

    Started work on instilling aftermarket engine management on my stagea ran into a few hurdles one being relays and there location i understand the fuel pump has a progressive voltage feed ? and i know the relay in the kick panel next to the ecu is ecu switched but where is the coil and high current relay ? also the stock rpm gauge is it simple pulse or digital signal or voltage i have looked and looked but all i can find is circuits to convert was to aftermarket tach if i can get this working on the stock ecu wiring end it could lead to an aftermarket plug and play for the s1 stagea almast had it running today on the aftermarket then the relay issue arose so unsoldered everything and reconnected stock ecu fired straight up

    still working on this issue guys loads of info for the s2 but not so much for the s1 is there a way to get the led to flash ?
  6. centoproject
    thanks mate we tried that and it just went through also ran it through generic search annoying thing is it had option for stagea like said top of the range.. do we know what consult protocol the s1 uses and are the engine and abs module linked ? thanks
  7. centoproject
    Right chaps diagnostics cable found now to somehow extract fault codes tried my pals tester top of the range but only lists r34 and s2 stagea. will the bridging work on AN S1 and will it get codes from atessa/abs ?
  8. centoproject
    i have looked right under the dash i can see the grey plastic bracket from its plug where it looked to have snapped off of its mount i may remover the lower dash section soon
  9. centoproject
    looked into this beforehand pal unless yours is an s2 ? won't work i don't think the main problem for me is the fact i can't fine my diagnostics plug almost like it has been cut of
  10. centoproject
    same boat as you pal no flashing just 4wd and abs light ?
  11. centoproject
    Right not to leave a thread without a conclusion 6 is back and strong just abs fault to go cause was a tiny carbon trace burnt into the ceramic therefore failing to spark properly on 6. thanks for those who threw ideas out
  12. centoproject
    right 6 i seemingly back reading further into the mines ecu it seams that it is tuned for jdm grade fuel around 100 ron ? so i found a fuel supplier claiming 99.9 ron cleaned number 6 plug and started it sprayed with water again and 6 is evaporating same rate although after coming back from the trip i have found that 6 is seemingly not evaporating as quick also re installed recirculation valve witch has cured stalling at the lights but when i had returned home i found the return line had blown off so hopefully that had caused the rich mixture to flood the plug
  13. centoproject
    having changed and timed the engine serviced all of the belts ect 6 is still dead sprayed water on manifold from spay bottle and 6 runner hardly evaporated so timing is out of the question starting to think its somewhere in that loom still getting spark ect fuel volume is identical to other 5. so frustrating..... is this the most problematic stagea ever ?? determined to get it sorted ! may go full aftermarket ecu and new engine loom.. may look into spark plugs next go more basic...
  14. centoproject
    right i will stick with it then on other updates found a boost leak on all injectors upon removal of the rail i had noticed that the vac line for the fpr smelt like fuel could this be my problem all along poor or intermittent fuel flow/pressure waiting for serpentine belts then i will re assemble along with the disco fan
  15. centoproject
    should i stick with the visco ?
  16. centoproject
    still not given up been researching and found that timing out a tad and possible poor fuel flow caused by pump or fuel pump 12v feed apparently voltage drops as idle so common cure is constant 12v feed through relay also I'm changing timing belt and ancillary belts while I'm at it also converting from visco fan to 12v
  17. centoproject
    I know tell me about it ! i think best move move is to either eliminate all of the hacks and install a new un fiddled with loom from a known good car. or maybe send and auto electrician to have a field day although in uk at least they rely heavily on autodata for finding electrical gremlins and as for the getting it into diagnostics mode still need to find the port i would loads of ways that apparently work i.e. ignition on then off then drivers door switch 5 times i will continue the mission and get a quote for a loom if its not expensive i will most likely go that rout
  18. centoproject
    right i managed to get my friend to bring out his diagnostics equipment and the plug is not there i mean i looked everywhere is there a way of making my own from the ecu pin outs ?
  19. centoproject
    will do tomorrow afternoon i will start also on a side note some f**kwit appears to have cut the consult diagnostic port of ? well its not there anymore after my mate got his computer out as well ! is there a way of getting a pinout for making my own ? or should i just install a fresh unmollested loom remove all the boges ?
  20. centoproject
    i will have a look tonight pal my friend with a top of the range diagnostics computer will be trying to get codes for me for both this issue and the abs issue just to confirm again 6 is defornetly down after idling for about 5 mins i could grab No.6 manifold runner now this is just a thought but if say 6 intake cam was snapped could the fuel from 6 injector pool and run into 5 causing the sooting and popping or is that a bit far fetched ? as for ecu i should have mentioned that i had attempted to install a ecu master det 3 piggy back after playing with the settings for a bit trying to get it to adjust fuel settings it ran fine then boom i shut it off and it wouldn't start again so i removed the set 3 from the loom at the ecu plug end and still no fire up so i pulled all plugs and dried them out and cylinder by cylinder it splutters back into life (please note that there has always been a misfire and idle issues ).
  21. centoproject
    All assembled and the issue stays at 6 also another thing coming back from the test drive and this has happened before video attached best explains the issue please note the backfire and also the soot plus the engine dose run smoother than this regardless of 6 being out of action http://youtu.be/ilUMXeQUqMQ
  22. centoproject
    thanks for help i will try and get Nissan to read the codes for me much appreciated
  23. centoproject
    not yet pal although i think i will tackle the more likely candidates i think 6 runs intermittently due to number 6 manifold instantly evaporating water on a cold iso start unless the intake cam has gone and there is enough vacuums to partially draw through some of the mixture on 6 just seams unlikely and the valve train is almost silent at low idle just hear the injectors i will get the new spacers on tomorrow and test things out see if it moves swapped 6 and 1 injector to see if the problem moves
  24. centoproject
    may have the possible cause rear fuel rail spacer is not there so I'm printing out a new set of 3 and i will fit tomorrow night
  25. centoproject
    good call i will try that first as for cleaning if i can move the issue with swapping injectors i will upgrade the oem ones thanks i will report back tonight
