Air Temperature Sensor - Improving Engine Performance?

Come on, please, one of you guys take Robert up on his return policy and test his solution to what you guys have worked on and let the rest of us know what you think.
You've done all this work, we've kept up with your posts, don't stop this close to the finish line.

Thanks Gerry for your idea!

However, this is about a resistor and the effects thereof only. The Power FRK Module has NO resistors.

Let's see what resolves in this thread about resistance as a tuning medium.

Best to you!

Couldn't tell.....no sig diff. (I'm referring to the Aussie foam filters that BMW Atlanta sells.) I put them in both S bikes. I'll just keep the stocker in the R. It seems to run fine as is.

The Unifilter was a definite improvement over the BMC filter I was using on the R12S, but the RT never had a significant problem with the standard filter to start with so the Unifilter made little differences.

A write-up on constructing and flow testing graphs for a $10 home-brew filter using foam media from Unifilter can be found at my website. The graph include flow measurements for stock paper and K&N filters with and without the snorkel. This should answer any questions about K&N versus stock versus foam (at least for the 1100 form factor filter).

Greetings Bob,

Yes you are right. The filters will not tune a bike - They will only make demand for tuning as they free up the pumping losses.

Subjective opinions could be the placebo effect. Empirically there is a loss when added to a stock BMW. Worse with a performance exhaust (NO CAT) and NO tuning!

Thanks!

Hence my acquisition of FRK x 2. Problem solved. But you knew that.

Resistance tuning Ben!

Not air filters!

Stay on topic - Resistance tuning!

You spoke of it many times!

It would be comparing a

Please don’t use this thread as a platform to promote your product Robert.
I for one don’t give a rats what’s in a FRK, it really doesn’t matter.

Its not about flow as any filter has plenty of flow at 5000rpm.

Trying to curb discussion, Shirley?

We have an angry lady here?

Do you really think that we need to have another FRK thread?

[Bob Hancock]

Well, under the filter topic, you more or less asked about the mid-range flat spot? All I was doing was responding to what solved my problem, which I think is good enough bandwidth to waste in light of the rest of this discussion. My two cents.
HEY....I just noticed. I don't have access to a "cents" symbol. Is it hidden in here somewhere? (Maybe I need to start a new thread on that. )

As careful as anyone should be in disputing your opinion, it is possible you haven't taken a close look at the R1100S filter, snorkel, or my write-up data. I measured the stock R1100S set-up as equivalent to a hole about 2.3 square inches.

Given the size of the TB throat, does that sound OK at 5000 rpm?

Please have a peek at my graph.

BTW, a "Bennie Duct" and sticky foam filter (which also filters better than stock paper) comes in at 5 square inches.

This is about Resistance Tuning ONLY!!

That is the topic!

You Spoke of it OFTEN!

Make us proud of you Ben!

I was providing information not asking a question. If the Unifilter did not work for you that s fine, my mistake I should not of mentioned filters here.

[Bob Hancock]

No mistake Owen. These internet discussions ramble.... you know that. What you say brings something to my mind that I want to comment on and vice versa. Hard to mandate how the thread goes.

Greetings,

Here is an average fueling graph of an R1200 series @ 40% throttle.





Lean Eh !!!

Owen,

Stay on topic!

If we get into resistance tuning with filters then go for it!

[tm1100s]

OK, Foster, that's it.

Where do you get off posting hard data, anyway?


By the way, the hardware kit you sent had stuff I didn't even know was missing on my system!
