Default monitoring datas with DH and COBB AP
Anyone noticed difference while monitoring data with theses unit?
With COBB, I see 0 to .3 of knock, and with my DH, I sometimes see up to 7.4
LTFT with cobb: -13% to -10%, with my DH: -17% to -25%
I don't know which one give me the most accurate numbers...
my dh is version 2.51 ans my cobb is up to date.

-25% fuel???
does your exhaust smoke look like a diesel?
sound like the map you are running could be a bit better, or better suited to your mods

as far as whats more accurate, I always assumed both were reading how they should. id update your dh to the beta version of the software you can find on this site and try again. I think you have a version newer than this beta software, but from what ive read, the beta works the best.

I noticed similar differences with the AE scantool vs the dashhawk about a 5-7% -+ using the popular PIDS

i ment speed and latency from the sensor to ecu to obd DD scaling and such..... goal being to make it as acurate as possible. Im not saying the DH or he AE are wrong im just saying we are going to see what can be accomplished.
