AOS was tested via manometer at 4.53 so that is fine for now.
Leading evidence: 'Test via manometer at 4.53 so' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Check deviations' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Did you check the deviations after a good drive to fully warm up the engine?

I have a Foxwell NT710 and it uses Porsche terminology.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I promise I did the googling of this but I can�t seem to find the answer or understand the answer.
trying to look at fuel trims on the fox well nt510 elite. I�m in the live scan section and can�t find anything titled long or short term fuel trim�. Is it called something else?
thx!

Your Foxwell device will probably be similar.

There�s three data values on each bank that you should be viewing. I think it�s RKAT, FRA, and another one (whose name escapes me right now). They ought to be grouped together, so that last one will be nearby above or below in the data list.
If I had to guess, the third entry was titled something like �oxygen sensing� or similarly.
No problem. There�s also this video by LN Engineering featuring Tony Callas which really helped me understand how Porsche deals with fuel trims.

[QUOTE=996love;20170579]�understand how Porsche deals with fuel trims� gives me horrible flashbacks of tuning the Manifold Pressure Sensor on a 914 with DJET fuel injection 😂😂🤢

AOS was tested via manometer at 4.53 so that is fine for now. Add to this that I’m in the very early stages of light scoring in Cyl 6.
I think I can stave off the bore scoring for quite a long time so at this point I think my most pressing concern is going to be the cam pads with deviation around 8 on position 1. I can do the job at home and will pull the car off the road this fall for a chunk of time to complete this. I swear the more I dig into things the more I
don’t
want to know!
Did you check the deviations after a good drive to fully warm up the engine? Have you been seeing any plastic bits in your oil filter media during changes?
Yeah, that camshaft deviation isn�t looking good.
And although your Bank 1 RKAT is rich, it�s only trimming away one percent, which is an acceptable value. Plus, it�s on Bank 1 - the side less susceptible to borescoring.
I just watched the PCA and Jake Raby video on the cam shaft pad job. initially it seemed beyond overwhelming but the video does an amazing job and while I still slightly dread the task I do believe after watching that it�s totally doable in my garage. 1 year into 996 life and I�m really starting to realize what Jake and everyone has done for this car and the community. I am very appreciative!
