I'm still using the stock ECU, and you know what that curve looks like... when I cut back the ground straps and used VP Racing 109 race fuel, all the plug meltdowns just stopped. I see that the true NGK racing plugs have recessed tips ( ? iridium ? ) which are highly recommended for "true race engines".
I did rebuild my fuel delivery system from "tank to crank" and now all the plugs look like they should. I had very uneven fuel supply to the rails and I think the 300ZXTT fuel filter wasn't up to the job, so it got changed out too.
Never a dull moment on the track, eh? Great job at MIR last weekend.

Timing has always caused any problems I had with nitrous. Without timing control race gas is a necessity. My old setup included a 1 gal cell, pump etc with 116 feeding just the nitrous. Worked well but added a lot of additional parts and circuitry and you know me "keep it simple stupid". Now its just a 255 pump with the fpr at the tank for a single feed line and dual feed rail.
Have you decided what you will be using for engine management yet? Sticking with the stock 4th Gen ECU will work but with all the stuff going into that engine I though you might go stand-alone. If I had it to do all over again I would probably go Megasquirt just to have something to play with and give me a challenge. Down the road my next project will probably be an Revup engine with a CVT setup and Uprev or Cobb for tuning. Thats when I get sick of my current setup and I still have a few things to try out yet.
Anxious to see you get your new engine going, its going to be a handful. Any idea yet when it will make its debut?
Was a little disappointed in the number of cars racing at MAXUS 09, was hoping for a lot more. It was a pretty easy field except for the Nissan All Motor Unlimited and Aaron. It was pretty hot and my cooling system quit after my first run and was leaking water. I finally got one of the fans working at low speed and tied a rag around the cooling hose leak but temps were still way over 200 and I had to wring out the wrag after each run to keep from dripping all over the track. Probably shouldn't have ran at all, it was a recipe for disaster being 600 miles from home. It turned out to be a severed low speed fan signal wire to the ECU which prevented any fan activity.
