Cold running spark plugs...

I'm planning on running bigger injecters, walbro, fmic, remap and a few other bits and bobs and right now I have a missfire on hard boost so I'm ruling a few things out, also on low boost it come is in waves but still missfires a bit, doing the easy things first, plugs, fuel filter, redex lol gonna hunt for a missing vac pipe and or a boost leak round the intercoolers

using colder plugs will be great when you're thrashing it around the track. Problem is when you're driving normally (which is what most of us do most of the time) it will foul up the plugs

So shall I just get normal plugs then? Where's the best place to get them?

stick with standard plugs unless you're running 500+ bhp

 

don't bother with the walbro unless your fuel pump is on the way out

don't bother with a fmic, upgraded smic's are much better

 

what turbo's are you running?

Standard ones, I'm running the tt fuel pump with the na fuel pump ecu (as that's what I was told) however I'm also told I need to run a 3rd wire from the main ecu to the fuel pump ecu??? This is for the3rd speed??? I don't know enough about all this to actually do it tho :( could be another possible culprit for the fuel problem, yea cba with a fmic tbh /:

are you running an NA to TT conversion? If so, then yes, you need to use a TT controller and also run another wire to the fuel controller that doesn't exist in the NA loom

yes I converted from na to tt in may, Iv got the tt fuel control unit, the third wire thing is exactly what I need more info on, I need an idiots guide with pics tbh /: I dunno where it needs to go on the tt ecu or on the tt fuel ecu

Awesom legend!! I stuck a new fuel filter on and a bottle of redex and that seems to'v solved it at lower boost but it still getting pissy above 11psi /: I'm gonna do this 3rd wire thing and the plugs on saturday see if I can fully resolve it, standard engine should be able to have more than 11psi surely?
