Help!engine Light Indicator Comes On R34 Gtt!

You running standard boost levels and tune Mike?

Yeah bud, bought it privately awhile back "unmolested", only mods it had were a BOV and rear strut. Probably needs a tune at some point

[Cadmoon]

Can't tune the factory ECU unfortunately. Unless you put a NISTUNE chip on it. You should go back to 1.1mm plug gap when you put the splitfires in.

Bigger gap after the coils go in? Why is this? Don't need to compensate for the shorter gap with the Splifires?

[Cadmoon]

Biggest gap you can have without misfire is the best. The reason people gap to .8 or even .6 is failing coil packs or big boost. Since you will have neither you should go back to the recommended 1.1 gap.

You sir, are a gentleman - noted! Let you know how it all goes!

[Cadmoon]

No worries, that's what we're here for.

Hey Cadmoon, am I going to be right to re-gap already previously gapped plugs? As they were a 1.1 standard but I gapped down to 0.8 - only had them in for around 3000ks. These are the NGK BCPxxxES

[Cadmoon]

Yeah, copper plugs are fine to re gap.

If you have a primary ignition code it is the coils. Gapping won't fix a dodgy pack.

No but it can sometime get you out of trouble if you can't get new ones for whatever reason.

[666DAN]

Not with an R34, the primary ignition code means the pack (transistor) hasn't fired, hence no spark on the secondary coil. You gap away all day, no spark means no fire.
