Hey guys so im on the hunt for a ecu for my m35 vq25dd stagea and im struggling to get one with the code mec14-521 a1 3328 i can get the mec14-521 but not the last four numbers. I did see one on ebay all numbers matching but if i can would prefer one in nz , are the last for numbers important or are there any others that will work cheers

So on the 3 wires to the sensor there shold be 1 earth 1 12v ignition and a 4-5v from the ecu which when the sensor detects something it cuts it out which is how it knows when the cam is at, well thats the understanding i have of em. Might be a auto electrician mish

Yea thats what it seems I tested my ecu current to the sensors and i seem to not be getting the ecu current so back to the drawing board on that one

hey guys i know this post is almost 10 yeas old but im having similar issues but my m35 vq25dd, car starts but runs like ass and shutters when cold but after 10 mins its fine n starts normal, running a scan on the ecu comes up with 0340 camshaft bank 1 circuit. i have removed my intake to clean it n have more room. apon inspection im not getting a ecu voltage on either sensor with the ignition on, i do get a 12v constant and the earth is also fine. any ideas please guys

0340

So read the ecu n got error 0340 camshaft sensor circuit, have since removed the intake to clean it and so i have more space to work. It seems im not getting and current from my ecu signal wire to the cam sensors any ideas on this?

Do you know the best program to read a vq i know they don’t respond to most obd2

Hey guys my 2003 vq25dd m35 stagea has got a miss/stutter when cold. Its starts like crap and hesitates and stutters when its cold but after about 10 mins of warming up it goes away and drives fine and start’s perfectly it also occasionally gets a engine cheek light. Any ideas on where to start looking

Hey guys any ideas on my culprit on my miss fire been chasing it for months, my r33 s2 Rb25de has a slight miss / rough idle which can sometimes be heard when i give it a rev the thing that makes it harder is it comes n goes. Things iv checked n fixed are checked intake for air leaks there are none, replaced my coil loom with a brand new one, brand new spark plugs, reset the timing with timing light. Im going to be getting the injectors serviced soon. I done a compression test about 3 months ago and got 160 av so should be sweet there. Any ideas or tips highly appreciated cheers

Standard r33 20e loom n ecu but the engine is from a vl i pulled the engine to go Rb25 and a mate wanted to buy these off me but can’t figure out cc rating

Hey guys can anyone identify these injectors they are from my rb20e from a vl commodore the model number is a46-00 and there a greyish brown in colour, quick google only comes up with red n yellow in this model. Want to know what the off so i know the cc rating cheers

Hey guys im in need of some help with my r33 rb25de s2 thats misfiring, i recently had my car go for a wof at my local shop and when I picked it up my mechanic noticed that my no6 injector was leaking and it was also missing which it surely wasn’t doing before, i have sorted out the leaking injector and it solved the misfire for about a minute then it was back, i went along and checked a few things like vacuum leaks n with some start ya bastard and got nothing so i checked my plugs there fine, so i replaced my coils and it went away then it came back, it has done it a few times just goes away then comes back, all 6 cylinders are firing when it misfires but ones not running properly but unsure of which and why any ideas appreciated cheers

Hey man i had a fully charged battery throttle wide open and i cranked the car six times per cylinder yea its not all even results theres a 10psi variable from low to high which is ok yea was just seeing if its acceptable compression for a na that might get the cheeky turbo later

hey guys i recently done a engine swap on my r33 and i did a compression test its a rb25de s2 and got these scores (all in psi) 1-160 2-165 3-155 4-155 5-160 6-155 so a average score of 158psi, and my question to you is this good compression for a rb25de engine, all googling give me information on rb25dets so no use to me as turbos are normally lower compression the non turbo's. cheers cameron

Finally found the issue the dam air regulator under the intake now she runs beautiful cheers guys for the help
