I'm new at the whole FI tuning. If I get a Utec would I still need a wideband? A member on the forums has a Utec and AEM wideband which enables him to display his readings on the stock navi screen. I'm thinking about doing the same thing but getting a Zeitronix wideband instead of the AEM. I like the Zeitronix screen, because I can hide it easily and I can temporarily the use it to monitor my readings until I buy some gauges. So is the Zeitronix compatible with the Utec? And is a wideband necessary?

 

Yes a wideband is needed. YOu need to make sure your A/F ratios are good or you could blow your motor. Do you have a turbo or SC?

 

sc

 

Yes get one. I have the AEM wideband. It works well. Yu need one for tunning the car. On the other stuff. I am not sure.

 

+1 for zeitronex, my friend on this forum have s/c Vortech with w/b zeitronex ... u can take his advice usename: xav_350z
good luck

 

I can't speak to zeitronex specifically (I have AEM and am happy with it) but you definitely need to log and view AFRs to be able to tune.

 

Wideband is a must with FI IMO
btw, i have the zeitronix unit in my z (logs boost, egt, and boost) and im happy with it too. thats how i tune my z

 

 

whats so funny ? :/

 

zeitronix lol

 

stop polluting the thread dude :P

 

**** off

 

Play nice gentlemen...

u dont HAVE to have a wideband...ive had a procharger/turbonetics and soon greddy tt....i "might" buy one...they can use there wideband when tuning your car...up to u....

 

Just to make things clear... If you are going to tune your car yourself, you gotta have the tuner wideband which TXS provides to properly datalog A/F with the UTEC... Other aftermarket widebands are not going to provide you with the info needed to tune.. If you do not get the tuner, you gotta have a shop tune for you..

 

umm that's not true, you can use uti or mps datalogger and tune your car just fine. why spend the extra money that txs charges for their wideband

 

+1....

 

Well.... Isn't it recomended not to tune off the factory widebands as they aren't very accurate? And if you do have a decent aftermarket wideband (that isn't the TXS Tuner), don't you have to run multiple connections to your laptop (1 for UTEC and 1 for the wideband)?

But yeah, you don't *need* the TXS Tuner to tune... It just makes it easier since it is native to the UTEC. The TXS Tuner connects directly to the UTEC via a serial cable.

 

After spending LOTS of time with both of those programs, even helping UTI with his coding, In My OWN Opinion, I would ONLY stick with the TXS Tuner..

No I am not an advocate for TXS.. Just going off of what I have experienced myself..

 

I like UTI as far as the eye candy goes. I think the author has the right idea and I don't regret buying a full copy to help support his efforts. But (at least with my copy of UTI) -- It's hard to make accurate adjustments to a tune with UTI logs because UTI lags a lot behind what the UTEC is actually doing at any given moment.

When I compare native UTEC logs to the actual tuning map, the values are spot on. Comparing my UTI logs to the actual tuning map and I see sever lag. So (at least in my case) I'm back to using the native UTEC serial dump for road tuning (which is what I believe most pro-tuners do anyway).

To tune in native UTEC mode, you do need a TXS Tuner module.
