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.

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.

    • roof rail delete used to be a thing, they were made locally for a while too
    • I can get more photos of it here soon and I plan to make a thread detailing the process. I received the car this way and it sorely needs refinishing. That is probably the most appealing photo of it. Up close it is fading, cracked, and needs to be re-glued. Depending on their condition I'm on the fence between refinishing or making a new set.  Another angle hiding the pimples and razor pumps  
    • According to this thread the RS4V with build plate RC40 comes with the R200 diff @ 4.083 ratio as well (mine has said RC40 denotation). We may need to check if the axle stubs are the same pattern as well. The auto subframes have longer axles. However I think yours being a later Series 2 as well, we should have the same bolt pattern for the diff stubs. Unless your upgraded rear also has upgraded axles. Either way, I would not be opposed to pulling the covers to check so I can inspect that  fancy rear core  Also I don't have HICAS. I don't believe that should change things but I hope the people here with heaps more experience than me can correct me if I'm wrong   Let me know if you want to attempt to make this work and I can get some pictures of mine from under the car. 
    • It's not that straightforward. For example I have had this code because my ignitor/power transistor wires were unplugged. It knows something is wrong but has no idea what it means. If you want to actually diagnose this I recommend following the service manual flowchart for code 21. Ohm out the harness, coilpacks, inspect the ECU, etc. And again, it's entirely possible for there to be no problem at all but if you're running a different coilpack it'll trigger the code because it doesn't like what it sees.
    • If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.
