The sensor specs are ±1% for Combustion.
The timing trigger that I fabricated adjacent to Mazda’s timing wheel would be the area for greatest possible error. To check this a test run is then made where the engine ignition is cut at 6000 rpm and the throttle is opened fully. This double-checks TDC in relation to the logged actual compression hump. To my knowledge the rest are calculations. ![]() |

If you know the calculations they're running for any given reading you can easily perturb the uncertainties to get a culmulative percentage of error. That way you can at least know the accuracy of your results. From my glances you could be on the mark or you could be slightly off. Without the error it's hard to gage application to different stress/repeatabilty.

For aircraft testing instrumentation we had to recertify sometimes every six months. I don't want to certify different dynos for the FAA or DOT. I want it to be accurate but I will pass on recertification. Really I just want to know is this log an improvement or have I gone too far! I am using it just like our Datalogit tuning for AFR, transition, etc. http://www.optrand.com/Papers/fisita98/fisita98.htm Barry Last edited by Barry Bordes; 07-14-2010 at 05:54 PM. |
