The manual really doesn't have much in it. Dowloading the software and becoming familiar with the controlls would server you better then reading the manual I think.
Joe, If you have an AEM then it is able to log internally all of the sensor inputs for you. You won't have to go out and get a seperate logger. It might be that there are still the logs from the shops dyno pulls on your AEM? I would check that out first.
Here are some quotes from the intercoller spraying link that DGarje777 posted eairlier.I know I bolded those for emphesis there, but if your re read that carefully you will notice that when they dump a bottle of CO2 12 feet away from the car peak horsepower drops by 4.O ya, one last quote...
Haha, I would probably want to do a compression test to make sure that the engine is in a decent range. Other then that lowest you can find I would say.
If by aftermarket wastegate you are thinking of a Tial type one then what you would have to do is either weld the flapper shut on your T-25 and weld a flange on your exhaust manifold( hard to do), or ditch your wastgate assembly on your T-25 and then Weld a Flang on your O2 housing while...
I'm not sure why it is there either, but I ran my car with a 3in exhaust and no rear O2 sensor without the grounding wire and things worked fine for me.
So, you have an AEM now? Those things are great for tuning, but you can burn a whole in your motor pretty quick if you don't know what your doing. Just don't get to crazy with things until you fell like your confortable with it.
