Temp Spoofers

[jduke]

Opening the exhaust and intake without doing anything else will make the engine more lean. Which sounds like what you described.
Curious to see what the Booster Plug will do.
Just checked with Rexxer and for $300 they will flash a custom map on your ECU (you have to send it to them and I'm sure pay shipping both ways) that should add fuel on a more as needed basis than the across the board +6% the BP is said to do.
Looking forward to your comments.

I have a FRK temp spoofer but I'd go with Rexxer if I were you. It's only a little more expensive. Having ridden back-to-back (my bike/friend's bike), Rexxer is hands down the better performance option compared with the simple spoofer. But the spoofer is better than stock with the aftermarket exhaust.

They have a 100% money back return policy. If it doesn't fix it, I'll ship it back

The header has O2 sensors and the BMW dealer, and what I've read, makes me believe that the computer will sense the change and make some corrections

Another option you guys in the States have is Brentuning the American version of Rexxer

I did the same with my SuperMoto the gap between stock and a spoofer is the same again from a spoofer to a PC.

Rexxer has a USA office in Virginia.

Rexxer ECU Tuning, tune ups for European sports bikes and scooters in Yorktown, VA, a short drive away for customers in Newport News, Norfolk, Virginia Beach, Chesapeake, and Richmond

I just received my Booster Plug, thanks Jen. Fast, prompt service.
The instructions weren't right for the R12S but it wasn't a problem.
Remove both side fairings, remove the 2 bolts holding the tank on, lift the tank about 3".
Unplug the current AIT connection, install the BP, route the sensor to the front of the bike and put it back together.
I don't have time to test it today but it started easier, the idle was smoother and the throttle felt better. Hope to have some time this weekend to put about 50 miles on it and see.
I'll post here when I've had a chance to ride it.

Now I know a lot of what went on with mine but not everything and I realise it spent some time on a dyno well in actual fact most of the day!! But even allowing for the camera sound and many other variables its a billion lights years away from how yours sounds.

It's not struggling Chris, if anything I am bogging it down a bit not wanting to go back to 1st gear in a hairpin turn as it can be a little snatchy in 1st sometimes. It goes like stink.

I have some issues still, but those are completely different.

If you want your bike to not-bog-down, so that you don't have to downshift as often, richen the mixture a little. That will shift the mixture from the lean stoic setting of the stock bike toward Best Power Mixture. The effect is quite remarkable.

You can achieve that by adding an Innovate Motorsports LC-2 (with its Wideband O2), instructions here: Wideband O2 Installation Overview.

You can do the same thing by adding an AF-XIED (a microprocessor based data acquisition device) to a stock narrowband O2 sensor.

Your bike will still run like stink at higher throttle angles. You could also advance the HES a couple degrees.

I took the bike out yesterday and put about a hundred miles on it. Around town, 4 lane US highway and some Interstate miles. The Booster Plug is an improvement, probably more so around town than at Interstate speeds.
I think its fine for a pure stock engine like mine but I think the best option is to send the ECU to Rexxer USA and have them flash a new map for $300. I can't see any advantage for the AF-XIED, it actually costs more than a Rexxer map.
I might send my ECU to them after the first of the year anyway.

When you lambda-shift you know exactly what you've done to your bike, unlike chip-swapping/reprogramming, where the changes are secret. Although the Rexxar can change spark-advance, there are several advantages to the AF-XIED, which moves fueling toward Best Power Mixture:

1. The user can select how much fuel is added, it isn't one-size-fits-all, and complete ECU operation is maintained.

2. Fuel is added at small throttle angles, even in closed loop operation, where these engines are the most snatchy.

3. The bike can be returned to stock at any time.

4. When/if you sell the bike you can take the AF-XIEDs with you.

If you adapt Innovate Motorsports LC-2s to your bike, in addition to the above:

5. You get two programable, selectable AFRs that you can switch between.

6. You can ride and record AFR, even during acceleration and deceleration.

7. You can program leaner that stock settings if long range economy is needed. (Note: leaner than stock results in cooler EGT and cooler CHT.)
