Got Splitfires, And 1.0mm Gap=missfire (update) 0.8mm

[WogsRus]

HI All

so i got my new splitfires today, put them in, ran 1.0mm gap, and getting missfire at the usual rpm 4500-6000. Only running 10psi of boost, had no problems wiht old coils at 0.55-0.6mm at the same boost,

SO WHAT THE HELL. The reason i got these is to stop the missfire and increase my gap to increas mid range pull and fuel ecconomy, so gapping down is a bit of a waste of my money.

Is it possible that the earth might be a bit crap or something?

CAN somone advise me ASAP please

New or old plugs?

[WogsRus]

New ish, done about 50kms

[R31Nismoid]

drop the gap to .9 and see, and keep going down

Coils might not be seeing enough juice

[Guest 40th-edition]

thats what i was thinking man... coil is weak.

but if u r trying to cure a miss did u say?

there might be bigger problems

check your ignitor

[WogsRus]

It's a series 2 with no ignitor. In regards to bigger problems, what else can it be, could the problem be a CAS sensor or something else.

I am going to regap to 0.8 but this sux, hopefully i can sorgth it out.

I have no errors on the computer, it has been tuned, new pump and so forth, the car did not miss at 0.55 gap, but the coils were shot, i mean i could hardly see the spark.

[WogsRus]

Sorry should have explained. When i got the car stock it was ok, but soon after i saw some cracks in the coils so i silliconed them up and they ran for a bit and then got worse. SO i gapped the plugs down till they worked wich was 0.55mm.

I am running the copper plugs that everyone gets on here, the BPRS6 things, NGK, you know the ones.

My fuel ecconomy started to suffer as soon as the coild started to fail, so i am trying to fix this by trying biger and better coils with bigger gap.

[R31Nismoid]

Thats not the right plug code... you sure thats it?

There are a few that are similar.

If you gap them down and its working, you have a faulty connection somewhere and isnt letting the power through

Find the cyclinder thats misfiring and it will be easier

[WogsRus]

Ok plugs are BKR6EYA gapped at 0.8mm

[Guest 40th-edition]

So you have new or not stuffed coils in atm?

could be leads but ushally miss all the time when its leads.

sounds like coils to me, does it change as the car heats up?

[SLIPPERY]

so i got my new splitfires today, put them in,

id say theyre in

[WogsRus]

I just put in brand spanking Splitfire coils to replace the old coils that only ran at 0.55mm, and new plugs

CAN somone advise me ASAP please

You need a HKS Twin Power, the new coils wont alow you to run 1.0mm gap, they will still need to be gapped at 0.8

[Guest 40th-edition]

yeah k.

i would check all my risistances, such as coils (even though they are new dont rule them out) leads, also give your afm a look and clean.

[WogsRus]

Well series two with ignitor, did check with MM, and primary is 1.4k ohms, wich is standard for series two, series ones are like .6k ohms.

AFM is clean did that, just finishing the plugs and see how it goes.

BTW i am on my lappy next to the car while working so hence the responces on the run.

[R31Nismoid]

mm, you'll have to gap them too .8mm

Then no problemo

Unless you back off the boost to 7psi, then you can run 1.0 1.1

[Guest 40th-edition]

let us know how it goes... did u gap them back down to .8?

[WogsRus]

just doing some more changes, back soon

[WogsRus]

OK so

gapped to 0.8mm, still get a slight miss under 3 full load, bugga. I guess there must be something else wrong, not sure what though.

Any ideas. If my engine was getting crappy earth, would that cause problems?

ALSO installed an R32 wastgate actuator, and DAm, doe the car pull much better now.

HOWEVER also noticed with the splitfires, the car idles better, more pull through the midrange (this was before the actuator), and easier starts.

SO all i need to do now i figure out why it might still be missfiring.

I read somwhere that if the CAS is playing up that might cause some issues.
