Cheaper than crappy Yellowjackets too!

Genuine? Cheaper than yellow jackets?

http://www.skylinesaustralia.com/forums/topic/187108-jjr-coil-packs-vs-oem-vs-splitfire-vs-other/page-21#entry7236243

Have a search around here, someone did a comparison of fake Nissan coil packs vs. real ones.

FYI, even though my GT-R runs off the factory actuators (so ~12psi), the Yellow Jackets have been working fine for 2+ years, lots of km plus two track days. I run 1.1mm gapped spark plugs.

People had YJ coils fail, people had Splitfire ones fail as well. Plenty of info around here to make up your own mind.

YellowJackets - as good as they sound, as good as their marketing say they are.. they're only good for a stock application.

Once you start ramming in boost they misfire all over the shop.. then you increase dwell (as you do) and they die on you.

In my experience, Splitfires have always been superior even with silly dwell settings.

Exactly, you get what you pay for. But why risk buying ebay "Nissan" coils for $300 when you can get Yellow Jackets with local support/warranty, the seller being an active member on this forum? (that's my point)

Anyway...

That's not even the correct argument. Why risk buying yellow jackets at all, despite the warm fuzzies of forum trader and all that stuff, when they have a higher number of failures than Splitfires and don't save you much money anyway? I'd rather pay the extra and suffer the tiny failure rate of Splitfires than save 30% and near 1 in 3 failure rate that I've seen with yellows.

From my experience, stock application it works fine. So if your car is stock, and you need new coils, would you buy fake OEM coils or yellow jackets (assuming you can't spend more than $500).

Under the artificial limitation that I cannot spend more than $500 I would clean up my existing coils and/or buy some 2nd hand originals until such time as I had the money to buy Splitfires or new genuine coils.

Face it. $500 is co close to the price for Splitfires or genuine that the gap is almost meaningless.

Let's put it another way.....would you buy a known non-genuine Z32 AFM for, let's say, $100, given the knowledge that they do work and have been used by a number of people, or would you rather pay $200 for a known genuine one? The other part of that question is that the known non-genuine ones, whilst they work, don't have the capacity that the proper ones do, and therefore can't be treated as if they actually were a proper Z32 (ie you can't use the Z32 curve in PFC or Nistune). I see the Yellowjackets thing in the same way. They work, but they don't work well enough and reliably enough to justify the relatively small saving in purchase cost.

    • If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.
    • This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).
    • I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.
    • You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?
    • Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
