What tool is necessary for tweaking the turbotweak or extenders?
I really do appreciate the info. |
Mechanically/electrically...they may not be badly worn, but, they are surely gummed up, and, at a minimum, need a properly cleaning and flow testing.
With regard to tuning,, one needs at least a Scanmaster. It is a monitor that allows one to see what is going on with a single parameter at a frame rate of once each 1.4 seconds but it does not allow recording. As far as I am concerned, it is of more benefit of serving as a detonation guard as it reports timing retard at all times....and, timing retard is the ecm response to perceived detonation.
It does provide all the info required to program the chips.
For serious tuning, the PowerLogger is a necessity in my opinion as it allows the simultaneous display on a laptop of all parameters and can record/replay long lengths of data so one can sit back and examine a run at some 20 frames per second of data. This is invaluable for both tuning and troubleshooting as one can see what event triggers problems, etc., or, the effect of changing fueling, timing, etc has on detonation, A/F, etc.
It also feeds data to the Scanmaster at a higher data rate making it more sensitive to events. The SM's normal display rate of one frame of data each 1.4 seconds is pretty coarse on a fast car whereas it is stepped up to 5 per second when receiving its data feed from the Powerlogger.
The great thing about Powerlogger is that it allows one to take input from other sources such as a wideband O2, EGT, boost, etc. and display them in sequence with the standard ecm data. Makes tuning much better/precise.
For a newcomer, the danger is in being overwhelmed with data
At the beginning, a Scanmaster, a fuel pressure gauge, and an analog boost gauge plus a cd copy of the shop manual are probably a good starting point. Not to mention some study to understand how these cars work and what the terminology means.
With a car with as few miles as yours, the spring cleaning article on gnttype.org is a good starting point. My site has a lot of info on it as well, and a read of the Basics section may help you understand how to adjust things as well as how to avoid some of the myths that continue to exist among those that don't really understand some of the workings.
