so yea, over a year later..i finally broke down and bought a wideband. lol
i figured it'd be nice to actually tune the car off boost...lmao rather than just adjusting things by feel..lol i knew i wanted somthing that had datalogging capabilitys, so i started looking around at some of the units out there... since i did not need a display, (ill be using a laptop for display and datalogging) i ended up getting the Zetronix unit, because it includes datalogging capabilitys, with A/F, RPM, TPS, (all included with no extras to buy) and can also log EGTs (it comes with a pigtail to make an extension if you already have one, or you can buy the probe from them) and boost. the sensor range is 9.5:1 - 21:1 it does have an optional display,so that you can have a standalone display setup, if thats what you want/need. heres a pic of everything you get when you order the unit. heres a screenshot of the logging/display screen. ill have some datalogs and more screenshots for you guys later this week. -------------------- Former Team 5SFTE pro member ;)

naa, not really dustin...just been doing some minor tweeks here and there, the damn SAFCII is a peice of worthless junk IMO.
you know from our conversations, exactly what im talking about...lol just the whole way it manipulates the ecu is just bad when it comes to our cars boosted. i mean, dont get me wrong, the car runs good, and the SAFCII has helped with that, but, its really so crude, you can only do a very limited part of the big picture with it. for you guys that may or may not have any experience with the safcII, basicly it allows you to change the fuel on 2 different levels. you have a "hi-throttle" map, and a "lo-throttle" map. you have 12 selectable rpm points for each map. meaning, you can select which rpms you want to change your fueling at, X12. once you have that set, then you can choose where your "lo" and "hi" throttle points are. basicly, you choose that by selecting a throttle position for each. for example, IIRC the stock settings have it set at 30% for lo and 70% for hi. what that means is that @ any point below 30% throttle, the SAFC will use the "lo-throttle" settings, and at any point above 70% it will use the "hi" in between, the SAFC interpolates. so basicly the SAFC gives you a 2X12 map, based on rpm. the problem with that is that at any given rpm, i can be @ WOT, or barely touching the gas, and all the safc knows is under 30, or over 70. i can build boost @ under 30% throttle...so, i can be boosting, using my lo thottle maps, which is normally tuned much leaner, which is bad. thats the main reason im wanting to switch over to the emanage ultimate, cause of how much more control ill have with it. instead of a 2x12 map, you have a 12x12 map. so instead of having just a lo and hi tuning point, you have 12 different load points to tune with, which will give me a much smoother fuel curve, and that means more hp, just from tuning, and a better running, more fuel efficent car, on, and off boost. -------------------- Former Team 5SFTE pro member ;)
