What chip to get? If any...

[Bob K.]

Question,

I have a 1999 R1100S with the cat removed, a Unifilter installed, and a very mild mod to the air snorkel. The bike runs well. However, I have been wondering if I need to do something to the computer. I have some questions/concerns however.

Is it really needed? Will I even notice a difference with my butt dyno?

Which system is best PCIII, Techlusion, or one of the $29.99 wonder boxes that you can get on ebay that gives you remarkable HP, etc.

I know that there are several threads out there, bit many are conflicting. I hear about one being junk, one better than the other one, hard starting problems, not even really needed, etc.

I know lots of guys have experience here, what are some thoughts. At the cost of these boxes, I don't want to invest to be unhappy, or can't really even notice the difference!


HELP!!!

Talk to Robert Foster here on the list. He sells more than one aftermarket solution.

Given your mild state of tuning, I doubt you'll get much of a performance boost. If it runs well, I'd leave it alone and save your mod dollars for an exhaust. Better yet, suspension if you haven't addressed that yet.

It goes without saying that the cheap crap on Ebay doesn't work.

After a great trip down south, I figure that I need to step up and get a Techlusion. Now that I have no CAT, slight snorkel mod, and a UniFilter, I get some mild popping under decell.

I need some advice from the Internet experts out there. I see two different Techlusion models out there for my '99 R1100S.

FI-1031 - Does not use O2 sensor
FI-1032ST- Uses O2 sensor/ a few $ more

As they have took the time to engineer two dirrerent units for my bike, I am sure that there was a reason behind this.
I guess (hope) that someone out there can inform me of a reason why one is better than the other???
HELP!

I agree-it's a mild state of tune. If it runs without lean spots or surging, you not going to get a big boost. If you are lean, getting a lot of popping on over-run, a Techlusion is $250 and can reduce the lean condition. I like the difference it made in my R12S, but the full, open Akra and K&N really prompted the need to increase mid-range fueling.

[Bob K.]

I guess I want to get the Techlusion for two reasons. Mild popping makes me think I am lean now, even though I admit that the mods so far are not too extreme.

However, some day the exhaust cans will change, and as I mod things, I can adjust along the way.

Now, why two models to pick from?

[Boybiker3]

You don't have a problem, so no need to fix anything. The engine runs better with a foam filter and that compensates for any change in the leaner direction.

The decel popping disappears when you close the throttle fully (there's a software "switch" for detecting idle in every modern ECU, duh). You can then open the throttle a wee bit, if you need it that instant. If popping persists, your TPS might be set a bit high - don't set over .37 volts.

The Techlusion with O2 sensor algorithm is a mystery to me - a bit of an oxymoron when you think about it: how can you "correct" a feedback loop. I think it is just a way to keep the O2 plugs from jiggling around and maybe showing some kindness to the cat converter (none of them are still working, even if still installed). The non-O2 unit is a swell piece of gear that can add a whiff of gas and sweeten you driving; easy to install, set-up, change, and remove. BTW, it has an accelerator pump simulator - the Motronic 2.4 (and other n-alpha EFIs) perversely goes lean on acceleration - as far as I know, only the Techlusion and some models of PC address this acceleration shortcoming.

You can also add some gas by wiring a 30-cent resistor in the ambient air temp sensor line (either wire, doesn't matter which). Exactly like an FRK (which sells for hundreds of dollars), this fools the ECU into thinking it is a cold morning. It's a very blunt instrument and it doesn't change timing, a knowledgeable guy at RhineWest told me. I've posted the resistance value needed in a few places; anything over 1,500 ohms will add gas but likely as not, you won't notice a performance change anyway. I've meant to experiment with it but I hope somebody will and will report back to all of us.

Since BMW do a fine job with the ECU fueling, the only power left on the table is by cutting into the safety margin of their spark advance - for the last 40 years, they have kept the margin at 3 degrees. The RBIII can change timing but tuning, if done well, will cost you as much as BMW invested (that is, many tens-of-thousands of dollars).

Chips can change timing, such as the BBP chip which has 6 levels of heat or the RhineWest. I'm not sure if any Australian chips are available anymore - but I don't think they change timing, only address changes like a Staintune. I don't think the Laser chips change timing either, but let's hear if that is wrong.

yet another screen name for Ben?

[roger albert]

yes, with the usual technically incorrect babble mixed in with the valid stuff. One old dog who doesn't learn new tricks very well.

[ckcarr]

Look, over the hill...

It's... Boybiker4...

[SergioK]

Lol

[JonyRR]

I'm doing my doctoral dissertation in clinical psychology on the facinating subspecies of so-called 'psychologists' that use continuing psudonyms to spout illegable nonsense in linear fashion while desperately trying to sound technical and accurate.
My submission will include my naming it '****** syndrome' in honor of overeducated imbiciles trying to sound smart with a subset of escaped MKULTRA psyhrinks let loose back into the general populace.

I won't have to defend anything, as the facts are self-evident.

Lookat me!
I have a degree!
In psychologee!
Whee!

[SergioK]

Jony, excellent use of prepositional phrases. Makes it sound very accurate... and important too!

[roger albert]

Try more use of the passive voice. Makes you all dispassionate and educatedy soundy. Truthy even.

[JonyRR]

well shucks;
IF I knew what 'passive voice' meant, I'd be all over it.

I'm just a blue-collar Hick from Parkland, Washington that was able to fake it all these years.

my undergrad work was at the modern Heartbreak Ridge, and my postgraduate work was at that famous university, The School Of Hard Knocks. I'm still learning.

[boxercup]

Thanks Jony!

You never know...No Ben repeats the same spiel. Continuous Rumination and multiple personalities would preclude him from being included in that study.

Oh, BYW - Hi Ben turning into a boy biker?

[phoenixtexoma]

Jony: Speaking of "wiring," maybe we could wire this guy up to the electric fence in my pasture and watch some real algorithms.

UltiMap no longer provide chips so that is not an option.

Closed up shop for good.

Lennie -

Sorry to hear they are gone - good BMW things from Australia, not least your goodies.

I think Brad Black said none of their BMW chips adjust spark timing. Is that so?

[lennie]

boybiker,

thank you for the complient on my parts.

no, their chips dont adjust spark timing. fuel mapping is spot on and a shame I did not purchase a bunch of chips.

at least I have access to the FRK module now.
