CCP and EGR duty cycle percent. Is this normal?
I just datalogged after my tune and used TTS Datamaster to do it. The Charcoal canister purge duty cycle (ccp) percent when ever i give it gas goes up. My first 3 accelerations showed readings of up to 62.9 and on my two wot runs it only reached 37.3 and on a quick wot that quickly downshifted it only reached 5.9 and otherwise it was at 0. My egr duty cycle percent also showed 12.5 in the first 1/2 of acceleration and would be in every other rec #. I only used Freescan before and it didn't have these reading to see.
Like usual Injuneer had it in the writeup he has and answered every question i had in detail. In case your wondering the EGR will not run at idle or wot but on mine it runs during acceleration. The CCP runs whenever so i guess its meaningless to even monitor it. http://members.aol.com/InjuneerZZ/ScanMast.htm
