Hi Capaci,

I run EGTs in all our race cars, as well as a wide bands on my boosted street cars to make sure I'm safe, or agressive, on A/F depending on what I need on a given day. Only reason I want to run the carb on the Lola is plain old simple simplicty. Four barrel carbs work well, don't cost a fortune, and they are easy to tune. Natually I'll run the thing in on a dyno with EGTs to make sure it's all tuned in well. If we really get out on a limb, I can use with real time track conditions to re-jet when needed - but this is just a street and track car so over kill there.

I tune EFI cars too, do my Lightning all the time. Even the cheapie modifiers allow you a lot of control over timing, fuel in ranges, and many other parameters. Other complete systems I've been able to use like Motec, Wolf, and Megasquirt are really nice giving you full control. Looking forward to doing a Megasquirt on the TR8 we race next year when we go injected.

I fly as well, and use the EGT when operable, or my ear to lean for cruise when they are not operable, which I think is most of the time lately. Not exact, but it'll save a little per hour and keep the engine happy. There are some street car carbs with real-time adjustable mixtures, that is, they have leads fitted to fiddle with them as you go. Don't think I'll go that route though, just not needed.
