Nice page!

I made one construction change to my sensor -- I found a plastic kit box with an aluminum lid (from Radio Shack). I mounted the LED on the bottom of the circuit board (on the solder side, rather than the component side). I then mounted the circuit board to the aluminum panel, drilling a hole for the LED to stick through. This way, the aluminum lid acts as a heat sink (with exposure to fresh air) and you can still see the LED.

Thanks Bill. I'm still thinking to do a better mounting, so thanks for the idea...

Thanks. I'm pig rich. It's around 11:1 in 1st and 2nd and goes under 10:1 in 3rd at WOT. :eek: Will work on it. I'm wondering how much power could this mean... Jim said that I might fdind it more powerfull on the rich side, but I still hoping for some impovement. :p

I had it at 11,5 to1 but it didnt feel right
Now it runs better with 12 to 1 and more agressive advance curve
NO DETO
You will gain serious power if you take it back to 12-11,5 to 1
Whats your best ET ?

No official ET yet. :oops: Best ET with DM is 13.0 at 100 MPH on 15 psi. Hoping for high 12's on the track this fall. Don't wanna take her to the track till it's running perfect. I'm wondering, will I ever get there? :-? Anyway it's really hot out there now, so that's a good excuse.

You are in Greece, right? Which part? Beautifull country. I love it. Been there a couple of times...

Help,, I need a little help please,
I understand the WB02 allowing you to see your air/fuel mixture, (this is a great thing) however i dont understand how you adjust it if,, say you are runing rich at part throttle, it seems if you adjust adjust your fuel pressure you would change the mixture through the whole RPM range, so what do you do? it seems changes to injector pulse through certain RPM ranges would be the fix but how??
Sorry about being ignorant about this, but I am trying to learn.

Yep, you are right, you should do some custom chipping. However my concern is not part throttle stuff, but the different AFR's in different gears at WOT. Part throttle leanless can be solved with chipping, but I can't see the solution for consistent AFR through the gears. As far as which tables to modify, you should ask somebody more experienced with this. BG, Leroy, Dig etc.

Part throttle stuff is a little more forgiving because most of the time you are running in closed loop so the Sterms and Lterms can take care of some of the fine adjustments.
