  1. fuel injectors r33 gtr

    in G4+

    Posted

    Yes ok. I have innovate wideband im installing soon so will use that for ratios.

     

    Thanks simon.

     

    As regards to the actual ecu, what 'link' is it as my previous car had g4 extreme and you could see it installed with loom etc

     

    This one has few wires but is inside oem ecu casing....

    Measured across injector pins with ohms set at 2k....had readings of .156 across all injectors

     

    Does this sound right and if so does the link need to be adjusted at all or will it be fine with literally plugging oem resistor pack and new injectors on?

    Hi all.

    Ive recently got hold of a skyline r33 gtr.

    Its running a link ecu although not sure what one as its actually inside oem ecu casing.

     

    Now i bought car with 700cc injectors and the resistor pack removed. Previous owner requires these injectors back as they were not his and has supplied me with rc1000.

     

    Car is mapped relativley well....think its tad rich on cruising ....but anyways.....i need to swap injectors over but will this mean i need to redo whole fuel map or is there a way of keeping it even with larger squirters installed.....also will resistor (oem fitting one) interfer with anything.

    Apologies if standard newb question....always on the learn.

     

    Regards jon

  8. annoying issue

    Hi all.

     

    Recently started having a problem occuring and not sure how to go about sorting it.

     

    I changed when my aux fans kick in from 90 to 88 as was trying to get car to run cooler in traffic.

    Ive also changed my overrun fuel cut as it was set far too high up in revs making car run on.

     

    This is set to 1400rpm at ect of 80 across to 110 and a delay of 0.7 sec

     

    The recent problem altho i am not sure if these are corrilated is that after engine has warmed up and ive been for a bit of a drive the idle doesnt settle. It bounces from 1k to 1500rpm and eventually settles but at a higher level (1100-1200)

     

    On cold start the car will start and stay a lovley 850rpm steady.

    After warm up idle is 1k sometimes higher seems to vary unsure why.

    Also another note to put it after car is warm and turned off....the next time i turn car on it instantly revs to 3k...holds for a second.....then drops to idle then 3k then settles again.

    I was told that this was done to clear any excess fuel in cylinders due to the large injectors. 

     

    I dont really know all the terminoligy to start tinkering with idle settings so if someone could help or point me in the right direction that would be great....

     

    Thanks jon

    Soooo me again.....i was fed up so thought as one last attempt i would revert everything back to the way it was....driver 6....ign and inj and 6 cylinder configuration in firing order......and wham.... it fired up fine.....

     

    So i havent got a duff driver somehing else is up....possible earth....??? 

     

    Anyways....looks like i can make castle combe but will be looking in meantime for gremlins

    So had a tinker and this where im at.

     

    Checked how igt and inj are wired. 

     

    Cyl 1 is inj and ign 1

    Cyl 2 is inj and ign 2 and so on

     

    Ive configed ecu to run as 7 cyl as without doing so it seems i am unable to use driver ign 7.

    Ive used auxiliary outputs for fuel and ignition as shown in pics.

     

    On cylinder 6 ive swapped both ign and inj drivers from 6 to 7 (1 pin along on ecu)

     

    Ive tested ign and get spark from cyl 1 all the way to cyl 6 but obviously have to use "7" to fire the 6th coil and injector.

     

    I have spark in each coil and fuel from each injector.

     

    Started car up and it seems to run a bit better since changing firing order (see pic) but still isnt right.

     

    While car was running i pulled coils off one at a time starting with cyl 1. Engine note changed and it struggled

     

    Cyl 2 it ran no different

     

    Cyl 3 it nearly cut out

     

    Cyl 4 it ran no different

     

    Cyl 5 itnearly cuta out

     

    Cyl 6 it changes note but continues running

     

    All coil are sparking while removing but idle is lumpy and up and down

     

    Im stumped as to what is going on.

     

    Oh and i cant seem to upload the pics i took on my phone :-/

    Hi dave thanks for reply.

     

    I will have a look tomorrow but i couldnt find a way to use driver 7 without configuring it to think it was running a 7 cylinder car...??

     

    Im pretty certain coils and injectors are wired cyl 1 : ign1. Inj 1driver

    Cyl 2 : ign 2. Inj 2 driver  etc etc....

     

    Will have a ganders tomoz as need to get this sorted as at castle combe track on sat!!

     

    Will also post pics of what ive changed.

     

    Regards jon

    Morning....so i have taken injector drive 6 and wired it into 7. Turned the injector drive via ecu function to injection fired her up and it still doesnt sound right... have lumpy idle.

     

    Is there something else i need to do to injector/ignition as im running out of ideas...??

     

    Basicly i have done the following.

     

    Configured setup to be a 7 cylinder

    Changed firing order to suit....(spark on cyl 6 fires in order 4th through driver 7)

    Used injector drive 7 for cyl 6.

    I thought it were unusual that driver had gone down too. I am talking to link themselves but they replied quickly and now have seem to of forgotten about me. Am located in uk so not sure where to seek help with link.

     

    Anyways i am grateful for reply....i shall get on it tomorrow and let you know the outcome.

    Hi all new to this forum and the link too.

     

    Basicly i have a mk4 supra running the extreme ecu.

    Im new to it so still getting to grips. I am no tuner but know a few bits and like to learn.

     

    Few days ago cylinder 6 started missing....tried all sorts but turns out no signal coming from the ecu pin. So guessing driver has failed. Cars been running spot on since ownership (1year) )

    So anyways what ive done is told car its a 7 cylinder and swapped drivers for number 7. Ive also switched firing order so cylinder 6 fires as 7 and 7 fires as 6.

    The ignition test says its all fine as can hear coil firing so wires all good and its getting signal.

     

    Started car up and it sounda awful....banging away and missing/firing at wrong time it seems

     

    Have i missed something as in essence all ive done is swapped drivers around.....??? 

     

    Regards jon
