    Egt and twin scroll?

    My exhaust manifold is twin scroll. Do I really need two Egt probes or can I go off one side for at least an idea?

    Matt I've got four one in each runner, but I can't find anything with four egt channels so will just use all four for mapping then leave one in as a precaution. I'm just using the zeitronix set up.

    Ah right. So have four bungs in place and swap the probe over to each when mapping?

    Nope four individual egt probes so that each cylinder can be monitored during mapping.

    Pauls dyno allows you to plug all of them in together so he can monitor all four channels on the dyno.

    Ah ok cool. Another one, my manifold has two runners into a divided collector. Do I just place the probes in each runner close to the turbo or just use one probe per half of the follector ie monitor two combined runners?
