Tall claim. Post up the logs and let's all have a look. What you got to hide? If it is, what you say it truly is? Prove it. Why all the carny games?




If you had it. You would of posted it by now. Posted very clearly, so everybody could understand it. You been trying to convince people how you are a tuners for years. But there are some very basic things you don't know or understand. You are proving that over and over.


Maybe you should find a CRX or jet ski forum.

I couldn't agree more. Andy, post something useful or just go away.

Andy,

That is not what I was asking. Go back and re-read my question. Further, as I indicated earlier, I cannot read those picture plots.

Why don't you just answer my question in words, rather than posting pictures?

Oleboy, apparently, the only answer you will accept is "There is no advantage , keep doing what you doing." I don't know how to convince you that I feel the TT option is simply superior in every way I know how to look at it.

You guys would be shocked at the number of bikes that are being tuned with these methods and concepts every week. People that do not want to post data and comments here in fear of intimidation.

Have fun learning to tune.

Andy

Maybe you should learn how to look at data. DC and PW doesn't have anything to do with power. MAP x RPM does not model airflow.

The real difference is the person doing the tuning, not the device ...I think anyway.

Give me a dyno, I'll still not know what the heck I'm doing. For the love of wotzit we're still only talking about mapping VE tables ...THAT IS NOT TUNING YOUR BIKE !! autotune one day, you get different numbers if you autotune next week, who cares what the difference between narrow and wide is.

Unless you want to RUN a closed-loop all of the time (for what it is worth, looking at those traces) - in that case, PV doesn't work, PV+TT does.

but no doubt there will be another 15 pages in this or another thread on the same old same old, keep bumping your gums but I'm outa this one and off to ride my bike

Not arguing, just not understanding this statement. The MAP sensor is telling us the state of vacuum in the manifold and RPM is just telling us how fast the pump is pumping. While it is not a flow bench and is not measuring the inefficiency in the pumping process (flow loss due to friction, restrictions, air temp, etc.), why isn't MAPxRPM a reliable relative indication of air flow to use?

That is not it at all. The PV Pro/TT may be better for auto tuning VE tables . I don't know. All I know is they say that the basic PV can be used to map VE tables but that it is not ideal. Why not? If the whole AFR table is set to 14.6 and the VE tables are adjusted so that 14.6 is achieved in the pipes across the whole AFR map (open and closed loop portions), why won't the PV basic work? Why isn't it ideal? Why is it okay or any more ideal to use a wide band sensor (PV Pro) to map a section of the AFR table that will be eventually controlled with narrow band sensors?

That is all I have ever asked.
