I already have a microtech lt12s ecu, but im having ignition problems.

i will be running six coils and im looking at getting a microtech x6 ignition module to replace the standard one.

apparently they can handle more dwell.

all up the coils are $300 with mounting brackets and the ignition module is $150.

so both are still cheaper then splitfires..

$50 cheaper...

to bring in another element of questional reliability and so on (when factory/replacement factory is beyond adequate), its not worth it for $50-$100

So you are saying to get splitfire or stay standard??

my reliability is out the window at the moment with the setup i have so i need to try something hey..

bullshit

it'll only be a problem if they arent installed properly

not bullshit at all.

when you change something from factory (thats worked fine for 20 years), you bring in another element to track down, makes things harder to look for etc.

The more stock the car, the easier to diagnose common problems.

When you've changed everything but the kitchen sink it makes it harder.

My car uses more stock parts than ever before (when i had a RB25) and troubleshooting now is a piece of piss

No that's not what its like saying at all.

You can change what's needed to achieve a goal, however changing something that isnt needed, serves little to no purpose which is whats going on here altering from the factory setup

Why are you having ignition proplem's thou???

Go to the main power feed wire for your coil's, (will be white or white/black) see what voltage you have on idle, then rev the engine up, as your alternator charges up to 13-14 volt's, see if you get the same reading at your main coil feed wire??

I bet you dont, which mean's on full load, your getting voltage drop, and your coil's are breaking down...

Try it.

Try it.

i tested the feed + wire earlier before reading this but i didn't test it while it was running.

I'm getting 12.2 volts with the ignition on but not running and the battery measures 12.4 volts.

I'l test what you said soon and post my results.

thanks for the help.

i also changed my spark plugs again and removed some fuel from the tune when off boost

i think it's an over fueling issue also compounding the problem.

but i dont have a exhaust sniffer (air/fuel) meter so i'm a bit cautious of leaning it out.

Well thats .2 of a volt lose with ignition ON, wait till you rev it up then if you loose more than 1volt, imagon that on full load, you would end up loosing 3-4 volt's to your coil's, there is your ignition break down, not the coil's fault.

Hope that help's you out.

Goodluck.

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
