Innovate Wideband Question

Innovate Wideband Question
Could the calibration be off on my Innovate? Around town cruising on the stock ecu I am getting about 14.5 AFR. Under WOT I am getting 12.5-13.0 AFR. I asked Jeremy and he told me not to trust it, but it is bugging the **** out of me. The engine is running strong with no detonation. If it's not accurate I'm pissed I spent the money on this POS. Anybody else think they are getting innacurate AFR's? What can I do to check it's accuracy?

My Innovate is usually real close, but the day before the motor went it would read a E8 code and a few minutes later it would read correctly then back to the E8 code and so on and so on. Does anyone know what the E8 code is? Can you take it by a shop with a dyno and just have them hook up a sniffer to compare your A/F? Is the sensor tapped into the drivers side or the passenger side?
IIRC the gauge is supposed to be calibrated once a year.

E8 is sensor timing error. That's what mine showed. I just replaced the sensor and it's good to go.
As for you Jet, mine has read .1-.3 higher than the dynos I have been on, but never that high. Just try recalibrating it.
E8:
7.7 Sensor Timing Errors
These errors are typically encountered when the sensor does not have outside air available as
reference gas. If you encounter this error, restart the LC-1 and operate the sensor in free air. If
you still encounter this error, the sensor may be bad and needs to be replaced.
Replacement sensors are available from your nearest VW dealer under the VW part-number
021-906-262-B or direct from Innovate Motorsports.
Sensor timing errors are also common when the sensor overheats. Relocate the sensor further
downstream in the exhaust, install a heat sink or Heat-Sink Bung extender (HBX-1).
Sometimes it’s possible to encounter Error 08 when the exhaust gas suddenly gets too rich.
Normally the LC-1 will display a ‘too rich’ indication if the exhaust gas is too rich. If the mixture
gets rich very suddenly, the LC-1 cannot distinguish between a too rich condition and a sensor
timing error.
LC-1 Support can be found here http://www.innovatemotorsports.com/s...C-1_Manual.pdf
Mine was over heating so we moved the sensor back after we replaced it and no problems since.

Jet, im talking in general terms on what can kill lamba sensors.
* If u were running too rich and your sensor is not placed optimally (manufactures specs) in the exhaust stream. Fowling can occour.
* Pre-turbo sensor exhaust leaks.
* Mis-fire events. Anything that will cause fuel not to be combusted will mena the fuel is not read by the sensor.

Larry,
I had a loose positive battery terminal
that was causing all my strange electrical issues. One of the issues was that my WB was reading 1.0 -2.0 points leaner than it actually was. As soon as I fixed the terminal, my WB reads just fine.
The other possibility is that JT tuned your car to an A:F of 12.8. That's typically an A:F ratio for max power production.....if so, I'm sure he adjusted the timing accordingly to make it work. Most tuners seem to tune to low 11s in an effort to "cool" the combustion chambers, but I recently read an article that had data showing that fattening up the A:F to low 11s only cooled the intake charge by about 5 degrees. In the article, the conclusion was that the car made more power at 12.5:1 with less timing than it did at 11.5:1 with more timing.
Just some food for thought..........

My Innovate also read a little high compared to my last dyno. The last shop that did my dyno just put the sniffer at my exhaust tip and I'm wondering if which one is more accurate, Dyno or my WB.
Before my Innovate read around 16.4 when the car is off but now it seem to read around 18 - 19 when the car is turned off...

Will a load on the car cause the AFR to lean ex.. from a dynojet to driving on the road?
I have a friend who owns ashop with a dynojet. I was thinking of putting it on his dyno to chec kthe AFR, but his dyno obviously won't put a load on it either.
Will open dumps change the AFR? I heard that but I think it's impossible since no air is getting int othe exhaust gas.

Did you have the dumps installed when it was tuned? If not then yes the dumps will cause the AFR to be leaner. They will affect spool time which will require the fuel curve to be adjusted.

By reducing backpressure... When the wastegate opens to dump excess boost, it will not occupy the same space as the rest of the exhaust flow. This should allow for a quicker spool and for slightly more efficient operation of the turbo.

Are you runninga Fcon with a navigator?? If so get ride of that Ino gauge, I did that thing runs great for a while then does its own thing. Jeremy right dont trust it.

use the new HKS AFK which reads the left and right side bank of the engine indivigually also its has a knocking sensor alarm .. really accurate piece worth every penny. the car drive way smother with it

i had Innovate wideband on my z and the A/F after 1500 mile went bad after that it start to affect the Fcon reading. just get ride of it
