im not sure why you guys are asking which wideband, the fact that its displayed on the dyno graph tells you that it was the dynojet wideband.

one thing i learned, is that the dynojet wideband, in my experience, never reads too rich... with a clogged filter or poor tubing into the exhaust it will read leaner than the car really is.

bigmike, call the dynoshop and ask them what yoru graph is if they change the correction to STD. STD correction almost always reads higher, and 20hp could be realistic depending on exact conditions... its possible the dyno numbers that were previously shown to you were STD correction.

BTW guys, it clearly says SAE correction factor of 1.01 on the graph... am i the only one that can see the graph? the car actually laid down about 1% less in uncorrected.

the smoothing is set to 5 on that graph... you would pick up a couple ponies (not for real, just on the graph) if the smoothing was set to zero.

its not a definate fact, but my opinion is with having dyno'd literally 100's of cars on the same dyno, that its possible that the wideband setup on that dyno needs maintenance and i am basing that on the fact that the wideband graph is extremely smooth in its transitions. i hardly ever seen a viper running a A/F that smooth.

I only asked if it was the dynojet wideband because I have seen someone integrate an Innovative wideband into their dyno to read on the logging software.
