hi
so far im a happy customer! running r20 on my 2006 r/t daytona charger
i have a few questions ...searched but didnt find exactly what i was looking for... so here goes
1)how to make the fans coming on early? i have the 180 tstat and live in middle east(sea elevation is only 33 feet) so its crazy hot here.. even with the 180tstat the eng temp keeps going to 100- 101 centigrade ...
2)how to see my AFR ratio? particularly at WOT
3)is the afr ratio calculated (particularly at WOT) accurate ? (i mean should i get a wide band afr tool or not) we dont have dyno here
4)im running 97 octane fuel here with the canned 93 CAI tune (i have mopar CAI, exhausts)
5)when my headers,camshaft and heads come what parameters should i be looking at for making sure im not too lean ????

plz plz help !
thanks

1. Lower the onset temps by about 15* across the board.
2. You need a wideband to see A/F ratio.
3. "
4. Thats fine.
5. At that point you will NEED a custom tune from a CMR dealer.

Thanks

one more thing.. i disabled the MDS.. but the predator also disabled the EGR... i have no idea what EGR is .. should i leave it off or re enable it
thanks for the quick answers !!!
someone told me if i hook the predator to a laptop for live data viewing/recording.. the open loop FA is actually the AFR? is that true ?
if so how accurate that is? cos when i WOT it drops from 14.5 to 10.3
thanks

When you disable MDS the EGR parameter will appear to be disabled but it is not until you do so.
The AFR in the dataviewer is only accurate if you have stock air intake and exhaust, even then it is not nearly as accurate as a wideband, i would not go by that value at all.
