Get rid of the LC1 and move on to anything else. I deal with them constantly and around 2 out of 3 I have seen have needed to be sent back for constantly loosing calibration. Getting one that works seems to be like russian roulette. I got lucky and bought one years ago for my daily driver that has never lost calibration (I use an Apexi Turbo Timer as my display), but most dont seem to get this quality. One thing I would say... I would rather have a wideband that was off by 0.2AFR than to have one that needed constant attention to keep it working.

 

true, and I suspect the .2/3 off is because of ground offsets anyways...

Personally I would rather not have to buy another one, but I have lost confidence with my LC1 and that makes it pointless.

Anyone know the best/cheapest place to get a ZTX?

 

I bought a lc-1 for my first wb and i installed it myself and it was fine for a month. Then it just stopped working. So I just contacted the shop I bought it from (Dyno Tune Nitrous) and he said send it to me and Ill take care of it. Got my new one in and has been working fine since.

I use evo scan all the time on the car atleast once a day and I have not had to re-calibrate nothing.

I have the lc-1 on the downpipe more towards the back of intake manifold way before the cat though. I also run it as my front o2 simulated narrow band with the yellow wire and have no problems at all with drive ability issues.

I was thinking of buying a Zt-2 to install where my front o2 is and just hook that heater ground to it so I dont get a cell and I'll have two wb signals to see the differences in the two.

 

installing a wideband into the front 02 position will destroy it in next to no time...

 

After all this talk, I am definitly going to keep my ZTX. I will try logging using analog to see how close it is to using serial logging. I might have to play with the groun location but if I can get it to be very close than I will use analog.

Especially with mrfreds new closed loop wideband patch.

 

With a good ground location, I think the analog out will do fine. ZTX likes the serial out because its a more direct value.

 

If the analog turns out to still be off even with a good ground I will continue to use the serial for tuning purposes but I will use analog for controlling closed loop operation as I think even .3 accuracy is fine for that.

It would be nice to only need 1 cable but accuracy is also important.

It's going to be nice when the new tactrix cable comes out with the ability to log directly to an SD card, then having AFR readable through the ECU will be very handy.

 

I will do this later

 

as far as i know the authorized zeitronix dealer are RRE and TTP. I bought mine from TTP and the transaction was quick and easy.

 

I bought mine from TTP with no problems, he usually has a sale on them every once in a while, might wanna wait for one of those.

 

oohhh interesting.. how much are his sales? might contact him direct :P

 

Here is a link to the last time he had a sale. If he does it again the same time this year then you have a couple months to wait.

[QUOTE]Tephra, join the hundreds of others within Innovate's own forum that experience the same failures you have.

Zeitronix and yes they are trouble free.

The innovator of the zeitronix came from the medical instrumentation field where precision instrumentation and reliability become of life and death importance.

No calibration needed.

Self calibrating.

Circuit protection. Even a monkey could install one, even if they reversed polarity and tapped 13 wrong wires before they got it right.

Out of the box, the system comes with proprietary software that is excellent to log, trace, read, scroll and save.

It has many options for kavlico precision 3.5bar and 5bar sensors. It can read in a selectible CELCIUS, FAHRENHEIT, PSI, BAR, AFR, LAMBDA.

Out of the box it comes with tach input, TPS input, AFR, and AUX USER1 input for raw voltage logging.

The logs can also be split into smaller logs and separated by numeric points to isolate specific logs.

The logs can also be output to excel format in tab deliminated format at 74 samples per second. The fastest sample rate I know of.

It is a modular unit which you can add on MAP sensor, High speed K type thermocouple for EGT logging.

There is a programmable safeguard and warning alarm module you can use with it that can program simple alarms such as "900*C EGT" or complex warnings such as "IF BOOST 20PSI> AND TPS 70%> AND AFR 12.2>, THEN TRIGGER ALARM".

In the end it is an amazing unit which we owe much of our successful tuning career to. They have been trouble free on all of my personal Evo's, customer Evo's and we even have integrated one onto our 2008 MUSTANG DYNO AWD-500 SE EURO and it continues to work flawlessly.

As the master distributor for ZEITRONIX, I'd like for you to send me a PM so we can answer any other questions you have about the unit and get you taken care of.

Thanks Tephra.

 

Let me analyze your way of thinking real quick.

What qualifies the Dyno Dynamics wideband as being more accurate reading leaner?

Could you imagine for a second that there was no dyno there at all.

Now which one is more accurate?

Just because a wideband is connected to a dyno, DOES NOT mean its accurate.

Furthermore if the ZEITRONIX is tapped at the downpipe or testpipe and the other dyno pickup is at the tailpipe, then the tailpipe pickup WOULD READ LEANER because it is closer to free-air and the sample is diluted.

This is why we ONLY tap the upstream exhaust and do NOT use tailpipe clamps on the TTP-Engineering Dyno.

 

Scott, I don't think this is a fair argument. Yes, many people do post in the Innovate forum with problems ... but why else would they take the time to post anything other than problems there? It's a support forum and people post there when they have problems ... it's logical.

I've heard people say that changes to the LM Programmer don't save, loses calibration, changes to a different fuel setting ... never happened to me. Mine has worked flawlessly from day 1. Maybe I'm in the minority ... I don't know.

Either way, I think Innovate and Zeitronics are neck-and-neck in the WBO2 race. They both have good products to offer and it's really a preference thing. If you want the simplest WBO2 logging tool, get the LC-1 for cost alone. If you need to log boost the Zeitronics unit moves to the front. Beyond that it's honestly the flip of a coin.

I will agree that a dyno doesn't make any sensor more accurate.

Tephra .. sorry you are having trouble with your LC-1. It would suck if you had to buy a new setup.
