Syvecs Forums

There are some on here who will say each and every sensor needs its own calibration ( que Rice Racing :) ) and they no doubt have their evidence to support that. So maybe that might be an option for you to to have your sensor given a test and calibration chart to use. I've only done a few cars, but...

We took the syvecs lambda sensor out of the bung today and placed it down the exhaust like the aem and reads perfect put it back in and now we have the offset this is only 6 inches max from each other
I think it's been mentioned that we might not be getting a true reading with how the exhaust is

Iv just took the lambda loom out and fully checked it and refitted exactly the same!

The thing is we have tested on another car with the same setup and that reads perfect! It's bugging me so much now as we can't find anything wrong

Fuel is largely irrelevant, as it's fair to assume both are using the normal petrol scale, so normal AFR numbers are valid. More importantly...is there an actual running problem or change you're trying to resolve ? Which reading do you suspect to be wrong ? If you feel the NTK AFR's have changed ov...

Good point tim
Well the car runs e85 at the track but we have tested with both e85 and v power.
We are getting the same difference
My friend has the same setup as me syvecs s6 ntk sensor so we did the same test on his car both sensors reading the same value at idle 14afr

Hi guys Iam having some trouble with my honda civic drag car running a s6 with a ntk lambda sensor the car has been fine in the past and ran times of 8.7 @169mph but we are now having a problem with afr readings. We put a second lambda sensor (aem with gauge which we know is good) in the exhaust ver...

just got hold of some sunoco e85r
put it in the flex fuel here are the results
sunoco e85r = 81%
vp racing = 61%

why is this?

Who tim?
Vp e85 should be 85
This bioethanol is 95 percent ethanol but don't know if it's safe to use with vp e85

just got some drums of vp e85r delivered and tested a small amount in the flew fuel sensor and exactly the same raeding as i had before 65percent.
i seen someone saying about using bioethanol used with fireplaces to bring the content up
is this safe?
thanks kiel
