In some very rare instances it may be necessary to capture photos of the spark plugs. If you have been instructed to take photos you must only do so after your WOT fuel and spark is dialed in completely. It's required to swap in a new spark plug; It doesn't matter which cylinder, which ever is easiestly accessible. Replace the plug with a new plug and go out and make a WOT pull. At the end of the pull while still at WOT, key off the ignition and coast to a safe area to remove the spark plug and save the datalog. This is most easilest performed on a chassis dyno. Snap a good close up of the backstrap showing the black burn mark across the middle. Be sure to have the angle so as that all the plug threads are visible. And another photo from the top looking down into the ceramic (I need to be able to see the bottom down inside there). This although spark plug photos are only needed when requested; you can optinally perform this as well if you want to be overly cautious in verifying your ignition timing at WOT. If you do not have a digital camera, a camera phone is ok. You can attach the photos to your Private Tune Progress Thread or text them directly to my mobile. |
