EGT gauge users inside> FI application, What cruising EGT temp are you showing at highway speeds? This recent build is at 1200+, is that good or bad?
TIA..
Joe.

Re: EGT gauge users inside> Joe,
I think that you might have better luck getting this answered at www.turbobuick.com, quite a few of those guys run EGT gauges.

Re: EGT gauge users inside> Only problem with asking the Gn guys is there temperatures will be totally different than an our. A guy I work with has a Gn it runs 1600 deg at a AFR of around 11.5. Of course if he cranks the boost, changes what octane he runs, engine temperature, or anything else it drastically changes the temperature 500 degs or more. EGT is nice if you have one on each cylinder. Then you can see how each one is doing compared to another one. I would not use it to tune with since its not directly related to AFR.

Re: EGT gauge users inside> thats probably normal for highway cruise.
i have a 2 channel in mine, but i cant remember what it runs at on the highway. i use it mainly for track runs and it seems that 1450ish it a good number to shoot for. for my gn, i used to run 1550 to 1600, so there is alot of difference.

Re: EGT gauge users inside> Thanks for the replies everyone! I haven't used an EGT since 1995 and don't remember the conversion. When I get on the gas under boost, it will go as low as 1,100 so thats a bit on the rich side. But the 1,400 in change seems to be optimal on the highway, off to the dyno Sat.
Thanks again!
Joe.

Re: EGT gauge users inside> For EGT's, you really shouldn't go by them as an absolute number. The strength in their use is when you use them as a "delta gauge". Every time you make a change, see how it effected your EGT baseline, then use the information to tune your car back to where it was.

not to dig too deep lol
but what is the benefit of running a EGT sensor? im considering it for my turbo build but im not sure how its used to help with monitoring and "tuning" if you can use it for such a thing. I figure this would be a good place to bring this up since its been dead for so long lol reason im asking is im looking for gauges and i have a 3pillar pod to fill and i came across a boost/vac and EGT gauge. just wondering if this is really useful
