Christian,

Do you have any way of logging data?

EGT will go up as your driving and eventually hit an equilibrium depending on how hard you're driving. If you're driving harder, it'll go higher, easily into 4 digits.

11.1 is pretty damn rich, is it varying from 11.1 all the way to 11.9? That's a really big range. Do you know how accurate your gauge is?

If you do not have a way of logging data, I would suggest you get the equipment to do so.

this is the software that you will need, but i just realized in order to get the data out i am going to need to order a 60.00 cable, so I will have to wait for that to come in. I have already recorded a couple sessions I just need to download them (waiting on cable though)

Keep in mind that the stock AFR sensors read about 1 unit rich in the lower range.

yea i finally finished programming the virtual gauges and setting the ranges so it looks good. Now i will be able to log runs at any time and upload them to keep an eye out to make sure everything is staying in safe ranges. Once its set up it seems pretty easy to use, just had to learn the software. I do seem to be missing one of my temperature gauges though, it shows up on the monitor but I can graph it for some reason after I download it. I am going to call PLX devices tomorrow to see whats up.

thanks everyone.
