I started out at 12% rich but that caused a lot of sputtering. Finally settled on 8% rich at WOT. This is just the basic translator, nothing fancy, no power logger. Car seems to like 48 psi fuel pressure (line off). What setting are you guys using at WOT?
Best Translator setting at WOT?

The wot setting is tuned based on your wot o2#'s. If wot o2's are low, add fuel, if they are high, take fuel away. The idea is to target upper 700 low 800mv @wot in third gear. You can go leaner as long as no knock. I like to keep it safe and run a little rich.
I have tried different WOT fuel settings & settled on 0. The TT chip seems to provide adequate fuel w/o going to a richer setting. In fact, my car will sputter a bit at richer fuel settings. I run at 40 psi.
Easilly explained since the WOT setting knob is designed to work only with Extender chips, not TT chips. The TT chips have their own internal adjustments.
There is no "best" setting. The setting will depend entirely on what your car wants and can use. And the setting you end up with will be different for street and race settings.
Turbodave- can you explain this a little more? How does the car know if it is on the street or a dragstrip? Only difference I can tell is, at the dragstrip, you go 1/8th or 1/4 mile, which would be further than a quick street race. So please enlighten us. Thanks.
By that I mean, you will end up with different WOT settings depending on whether your are in street mode or race mode.
Your setup for the track will likely be much different than that for street use.
I.E. higher boost, higher timing, better gas/alky, etc.
Your wot setting would be different if you were running 28# of boost that if you were running 18# of boost. Fuel requirements would be much different.
When I was racing, I ran 28# of boost, 25+ deg of timing, and had the octane to support that. If I didn't turn the WOT knob up from my street setting (20# of boost/19deg timing) I would be extremely lean with all that boost.

Maybe I missed it, but if you aren't running an extender chip its not doing anything but richening up your mid part throttle boost (thats usually enough load to be considered WOT by the translator) Set it to 0 with a TT chip.
Thanks Dave but I don't think your reasoning applies to me. At 12% rich, my car sputtered so bad that it wouldn't even make 1 lb of boost, let alone 28. That is with alky and pump gas. My direct scan showed 21.4 degrees spark advance. Is that the timing you're referring to? It's programmed into the chip. I'm not sure if I can change it or not, but I wouldn't feel knowledgable enough anyway and would do more harm than good.

translator settings
HI rick, I have the same setup as you,mine was surging and missing with alky because the alky controler was interfearing with the translator. I had to get the power for the controler from the battery side using a relay turning the relay on with the ignition side.

So my surging problem wasn't related to too much gas at WOT? My alky never even turned on, as I couldn't make any boost. So I don't think the alky interfered with the translator.
Like I said, there's no "best" setting. Every car is different. You have to find the setting that your car likes. Might even require some - numbers.
But if you're running a TT chip it's all a moot point as the WOT switch ISN'T affective with any other chips, just the Extender chip.
