i have been weighing my options and have done tons of research, but still have some unanswered questions, and would like the opinions of those who are very experienced with the following products and/or "advanced" tuning (not just handhelds and whatnot). also, please read my sig first to clear up any basic questions about my GT.

first of all, i am planning on getting the Delta Forces Commando Kit, as it seems to be one of the most extensive tuners with the most capability for the price. now its to my understanding that the kit by itself can monitor/log AFR but only narrowband, which is nowhere near as accurate as wideband. now to my first question:

1)what wideband should i look into? I am trying to keep this around $200, preferably with a gauge included, and have so far found the AEM UEGO, Innovate LC-1, and PLX DM/SM series. The AEM UEGO's i've seen don't have any kind of computer software, so i'm not sure how i would be able to datalog with this for use with the Commando program. The LC-1 doesn't come with a gauge, and the gauges specifically for it are expensive, although i'm sure i could use another one.. this brings up question two:

2)do i need a gauge with my wideband, or will it be good enough to just have it on my laptop while tuning and every now and then for the occasional check-up? (as a sidenote, i do plan on having someone in the car with me while tuning/logging)

3)I am currently running LT headers and an O/R H-pipe, so since I am cat-less, will it be acceptable to put the wideband sensor in the same bung as the rear o2 sensors, and...

4) can i just use one wideband sensor? I've read that the driver's side runs leaner on cobras, but not sure about GT's. either way, will it be sufficient enough to just run the wideband sensor on the leaner side? two people have suggested this to me (a cobra owner and a 350z owner). i'm pretty sure that's what i'm going to do, but would first like to know which side to run it on and if it would be acceptable to use the rear o2 sensor bung rather than welding in a new bung.

5)i've seen some wideband kits come also with an EGT sensor.. do i need this too? what would i need this for, tuning wise?

thanks in advance for all the help guys!

 

1. I just installed an LC1 this weekend, and an AEM a few weeks ago. AEM was in in like 15 minutes. We $@^&ed with the LC1 for a solid 90 minutes before we even had it ready to start calibration, and that did not go right either. After about 2.5 hours we had functional AFR. Fun.

2. You dont 'need' one, but they are nice to have. The AEM for around $200 with the gauge is a really good value. The AEM does also have analog and serial outputs for logging.

3. Yes, thats fine.

4. Yes, one sensor is the norm, and monitoring the leaner side will work fine.

5. No need for EGT, but there are those who swear by tuning from EGT and would rather use that than AFR.

 

ok, i know this is a noob question, but how do i use the analog and serial outputs to datalog w/ the AEM if theres no software for it?

thanks for the speedy response!

 

The analog is a simple 0-5V output that I would imagine can be tied into the Delta Forces software to provide AFR on the PC as you log. They may even support the serial output from AEM, you'd have to check with them.
