    #1 how do you know your on compression stroke on no.1 cylinder. did you remove the plug to check this?

    #2 if you are running wasted spark, you will get a spark on both the exhaust and compression stroke of no.1 you need to rotate the cas so the spark your timing the cas with is the first one you get after the no.1 injector pulses. This is assuming your running sequential injection.

    I pulled the intake cam rocker cover off and watched the no1 cyl valve, and aligned the timing mark on the crank, with plug out to get TDC on compression.

    Now obviously I cant tell when the No 1 injector pulses as they all fire at ounce so how am I ment to set it up.

    Please Help, Cas Problem.

    Okay I have no idea how the coil packs are set up. They are splitfire series 2, so Im under the impression the ignitors are built in.

    The map u have posted is a different version of the software than I have....

    Hmmm, I have also read in the EMS help that with ems the CAS needs to be set 60 degrees BTDC which requires snapping the locating tang which might explain why mine is missing.

    When i say injectors all fire in 1 rotation of the CAS I mean they all fire at the same time?? Is that normal??

    Okay I just got number 1 piston to tdc on the compression stroke and set the cas so it was letting a spark at that point, still no go and big backfiring in both directions.....

    My set up is running a wasted spark so setting that is hard BUT, it seems for every rotation of the CAS it fires all 6 injectors??? Is this normal.

    I had the car running a week ago but it was very rough and idled at about 1400rpm due to a leaking plenum gasket, so I pulled the plenum off and sealed it up.

    Now Ive tried every concievable way to put the CAS in and Im scared to even turn the ignition on for fear of massive backfires.

    There has to be an explanation for this is there anyone running a stinger 4424 that can give me a snap shot of their ecu setup screen even though I havent changed any settings its might be worth a shot.

    Thanks very much for all the help so far. :thumbsup:

    from what i understand the are, except the very late model 33's have one the same as a 34.

    still running stock coilpacks?

    what you could try is: (just to check everything)

    unplug the injector harness from the main plug at the front so as not to inject fuel. pull the coilpacks out and place them where you can see them spark. manually rotate the cas and check that the firing order goes in the sequence of 1 5 3 6 2 4. you may not get that a first depending on your current cas position, it may start from 3, etc.

    if thats all good, then set the engine to cyl 1 at TDC. with the cas held the right way up, rotate the cas till coil 1 fires, then turn it around a very tiny bit more. that'll be where the right cas tooth alignment to the cam is, then put that onto cam and set the cas bolts so they are about halfway in the slotted holes. this will be a good spot to start till it gets running and you can get a light on it.

    then plug the injector harness back in. make sure they are plugged in the right way, and getting a signal. and your fuel lines are the right way around.

    if thats all good the only things left are your MAP sensor, and ecu settings.

    I did try that but the problem is Im getting multiple sparks at the same time. Im sure the computor uses a wasted spark setup which makes it hard.

    The other thing is it seems like the sparking is random depending on how fast I spin the CAS.

    How do I know which stroke the number one piston is on ie intake or exhaust?

    I tried unplugging the fuel line both into the rail and the return from the regulator and they both flowed a cup fuel in a couple of seconds but the pressure didnt seem massive, how much should there be?

    Everytime I try and start it now, I pretty much get nothing followed by massive backfires I mean BIG.

    One thing is I dont have the intake pipe on so its sucking straight into the throttle body although I cant see that making a difference.

    that tells me that the cas isn't lined up properly. or you cams are out. have you checked that your timing marks on the cam pulleys all line up.

    i know its probably unlikely, but is there anyway the ecu has been reset?

    I havent touched the cams or the timing belt since it last ran.

    The compuor still has the maps when I plug it into the laptop.

    Im ready to set it on fire.....

    Is the series 1 and series 2 CAS the same????

    yes, what ecu are you running? i just looked back to your first post and you say that you have fuel and spark, if the cas was faulty you would have these. how did you check for fuel and spark?

    on some aftermarket ecu's you have to tell the ecu your firing order for it to work. also whats you battery voltage like? if its low your coils may not be charging properly giving you a weak spark.

    Its an EMS stinger ECU.

    It was perfectly tuned about 2 years ago when I took the car off the road, and as far as I know none of the settings should have changed.

    To test spark I rotated the CAS and watched the spark plugs fire.

    I can also hear the Injectors ticking and my fuel pressure gauge is reading 30psi of fuel pressure.

    Okay, Im sure the CAS is in the right position and the F&*%ER will not start...

    Ive pulled the plugs and checked and they are sparking well.

    Its getting fuel and the injectors are working.

    My computor runs a map sensor so basically it cant be anything such as AFM or the TPS caus eit dosent have one.

    Is there anything else here it could be its got me baffled?

    Please Help, Cas Problem.

    Okay, so stupid question here,

    Does one rotation of the CAS equal six injector pulses or does it need to rotate 6 times?

    Is it possible Its injecting fuel into say cyl 3 and cyl 6 is the one that needs it? If you know what I mean..

    What Im saying is could I be 3 or 4 rotations out or does it just work on one rotation. :)

    Okay I recently finished a build up of my car and have finally come to the turn key stage.

    When I crank the engine I get all sorts of farts and blurps-Backfires etc but it wont run.

    I had the crank/cam angle sensor off and I believe this is the problem as I have fuel and spark.

    Now the problem is my CAS is not keyed so I have no idea where it should be?

    Whats the easiest way to get it to the correct point before installation?

    Do I just need to turn it a tooth and try again, and again etc.

    Engine is an rb25det (I believe series 2) with standard internals.

    Oh and when I pull the cas out and turn it the injectors pulse so Im sure its fine.

    Im at my whits end I just want it running. I have searched and searched to no avail. :worship:

    Thanks in advance.

    Please Help *urgent*

    The common solution is to use a throttle stop on the XF throttle body to control the idle rpm and piss off all of the ECU controlled idle speed hardware.

    :D cheers :wub:

    Could you please elaborate on this sydneykid?

    Are you saying not to run any of them including the two on the back of the plenum?

    Thanks.
