colortune

Hi Guy's I have just finished putting in my new cam and new Headers. I was wondering if any of you have used the ColorTune to set up your carb and if is worth the time and money thanks for the replies :thumbs:

I haven't used one in ages. It was great for tuning my old MG's with SU carbs. Should work on the vette it you can get access.

Re: colortune (DaveL82)

I use a color tune and they work great ! I run 4 dcoe weber carbs on a moon crossram intake with individual runners to each cylinder . This allowed me to make the desired changes to each individual cylinder . It is a bit of a pia but the results were well worth it !

Re: colortune (1977)

i've been successful with an O2 sensor at each cyl. see link in sig. for details.
Question: how do you test WOT with a colortune?
Have an assistant hang on to the fender as you floor it? :lolg:

Re: colortune (Matt Gruber)

Colortune would work on a chassis dyno. I'd wonder if you could see it well enough, though.

Re: colortune (L79vette)

Yes you will be able to see the color tune with the attachments that are supplied . Matt your point is well taken regarding the the use of sensors but,,, I really donot want to hack up my headers for each cylinder to tune a IR system . More people should read your tuning tips as they are a very good info resource .

Re: colortune (ram82fire)

Here's an alternate method for using the colortune to set WOT mixture:

This from the normally-sane David Vizard, the same guy who writes deep technical articles for Circle Track magazine. I don't want to be within 500 feet of a jacked-up car running wide-open throttle up against the brakes.

Re: colortune (L79vette)

Thanks to Vizards recent book(1996); that's where i learned to use an oxygen sensor.
