Which Wideband?
 

I am looking at getting a wideband to go with my EMB. I know that the Innovate is used by quite a few members on this board, but is there really any difference between the Innovate one and any other? I quite like the look of the AEM gauge 6-in-1 type controller.

Is there any reason why I should'nt buy this kit?

Yes, there is a HUGE difference

The AEM has a very noticeable lag when compared to the inovate.
Ive had both hooked up simultaneously and its an obvious difference.
Imo the lag is bad enough that I would never use an AEM for tuning (Ive done it, but it sucks)
If you just want it for mild tuning and letting you know if something bad happens, then thats fine, but if you plan on doing any serious fine tuning youre going to want an innovate.
PLX is supposed to be good too, but I dont have any personal experience with their stuff.

I recommend the 230 dollar LC-1 + DB gauge combo. The gauge updates as fast as the LC-1 can output a signal (Which FYI is *theoretically* fast enough to read each ignition event) and install is easy if you RTFM.

I've only used the AEM one time on a friend's car and I must say: DO NOT WANT. It is slow as hell.

I use the UEGO in my 252rwhp car and have put over 10k. Paul uses it in his 311rwhp car that's about 2 years old now. Paul's GF uses it in her 232rwhp car. Paul used to use one in his 230rwhp daily driver for over 30k (Paul drives a lot for his business).

Not one single problem with the UEGO. Very happy with it. Personally, I wouldnt deal with the calibration needed for the LC-1. But to each their own. Some ppl love it, others hate on it. This has been discussed many, many times.

The LC-1 only requires recalibration when you remove the sensor, so its not really that bad.

They actually recommend a monthly calibration.

Mine seems a little off (been 8 months), but tons of other variables have changed.

Just about anything negative you read about the LC-1 is from people hooking it up wrong.

A friend sent me this a couple days ago:

He said the dyno's LM-1 and his LC-1 were dramatically different by 1-full point. Then he told me that he had 4-GND's on one bolt because the shop who does this let me know that the electrical engineer on staff insists that stacking the grounds is OK. So he changed it to each GND on separate lugs and now it miraculously works.
