Trying to reduce Cfs LCR - APR Stage1

[ChrisGTL]

I'm trying to work out why I have so much CFs on my mapped LCR. I'm running an APR stage 1 with the following;

SAMCO TIP
007P
Jetex Cone /w 3" CAI
New OEM plugs
Toyo FMIC

Did some more logs today as the outside temp was low. 5.5C on the dash

APR is very aggressive timing, leave it stock timing and you'll be ok.

Cheers Willy.

So those CFs are typical for a APR map?

 

[Avant4me]

They are not massively high on 0 timing, but still more than i ever had. Weird how its just one cylinder. I used to get very high CF on my LC after fitting my turbo back exhaust, but it was across the board. After a custom map i got to down to below 2 even at spool up point which is the worst point. Have you tried swapping a spark plug and coil to another cylinder to see if the CF moves?

No I didnt think of it in that way. I suppose it is possible to get a weak spark plug, does those logs mean that the CF's are in banks 1,2,3,4? Bank 1 been the very most left bank as you look at the engine from front of car?

I've had REVO flashed to my car now and the CF's are much lower, I was able to put 1.5degrees of timing on without CF's been anything to worry about.

I've got a new set of NGK's which are one grade cooler, not sure if a stage 1 would run good on these though?
