hey!!! (ive made this topic everywhere.. but i shouldve done it here coz of the head im using)
bloody hell had to remake another account because i forgot my username, but hey I own a vl calais turbo and im just about to put a rb26/30 into my car..
the motor is out at the moment (i bought it off someone else who also had a vl) and just before i put it in my car i need to know what to do....
previously the engine was running off a microtech ltx12s (or lt12s if its the same shit whatever lol) and the car is still in its run in tune, at 10psi.
so having said this i could get the ecu off the guy aswell, and plug his into my car and away i'd be.
he also has a decent coil setup. but id probably give him my motec m4 and i'd pay less for the engine or watever ("cash adjustment")
now my dilemma.
im really confused and i have nfi what to do with my Motec m4 (which i still own)... it sez on their webpages etc that it can run upto 4 ignition drivers? then people said what u do is batch them or whatever..... but it wont be as good as the lt12s coil setup or whatever...blah blah
well this is what ive been told so far -
you can run a Motec 'ignition expander' (runs up to 8 coils) and use batch or semi seq fire for inj, no probs
Or if you want / like CDI ignitions, use the motec CDI-8 module, easy as. both of these interface directly with the M4 ecu.
and then..
"As trev and shazza said, if you dont wanna run the expander, just run wasted spark instead of sequential, with 3 Bosch coil packs and you'll have an ignition output spare.
I dont know who told you that batching them will make idle bad, but its totally not true if its tuned correctly. It just means that the coil fires during the power cycle of two cylinders, rather than just one"
i am soooo confused and dont know what to do ay.
all i know is i gotta buy atleast an "ignition expander" for 330bux or i could pay nearly 2grand for some CDI bs... which seems shithouse coz thats too much.
what do yas reckon is my best option.. go for the ecu which is good enough and is aleady tuned etc (microtech) or go the motec way???????
big thx.
ps - dont tell me to speak to my tuner lol, i will but its a public holiday on monday, so they wont be open and i NEED TO KNOW WHAT TO DO ASAP!!!!!
