Hey guys, got it dyno runed and experienced some popping, my plugs are at 1.1 for 231rwhp at 13psi

i have iridium bcpr6eix-11

i was told to reduce the gap to .65 to me that sounds to thin of a gap, would i get a better gain out of .7 or am i better with .8

cheers

I think if you just get bcpr6eix, you wont have to regap them if I am not mistaken?

I think they will come pre-gaped at 0.8?

The "-11" at the end, bcpr6eix-11, means there gaped to 1.1 right?

Im just assuming here, I know that is the case with the plugs I am using. BCPR6ES (0.8) BCPR6ES-11 (1.1)

Yeah I've heard it's something like that.

It's always best to go for the largest gap you can do without your car missing.

abu, why buy .8 plugs when i can just gap the 1.1's to .8 anyway.. seems silly :S

If you've already got the 1.1mm gapped plugs, regap them. I think what he was trying to say, is if you want plugs gapped to 0.8mm already, buy the plugs with that code.

It's always best to buy plugs already gapped to that size isn't it? I think it was iridium or platinum plugs you can't regap.

you can regap them, you just need to be careful. certainly better than throwing them out for a pre-gapped set.

i did my platinums against a piece of soft-ish 2x4 wood. soft taps.

Yep sorry.

What I was trying to say was if you want plugs gapped to 0.8mm, just buy them pre-gapped at 0.8mm instead of having to re-grap them down from 1.1mm for instance.

I think factory gapped plugs save you the hassle and chance for error.

I usually check the gap before putting them in, just to save time and hassle later, but they are usually at the correct gap as on packaging.

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
