2WheelDynoWorks - ECU flash - Review Thread

Here is my initial assessment.
1. The guys at 2WDW are professional and responsive. I had zero issues getting questions answered and communicating the payment, delivery and such.

2. Fast service too.  My ECU arrived at their shop last Friday afternoon.  Being a holiday weekend, I anticipated the work to start on Tuesday.  Tuesday afternoon I had an email with the return shipment information.  My ECU arrived today (Friday) even though I'm at the opposite corner of the USA.

3. The details.  

My wife picked me up at the airport this afternoon.  As we approached our driveway, the mail lady was leaving. The ECU was in the mailbox. YES!

My wife had taken the afternoon off because I've been out of the country all week.  I was worried that he ECU might be calling my name all day.  Luckily, she had a dental cleaning.  This gave me just over and hour to install the ECU and reconnect the battery. About 3m total time. 

The bike started instantly. No codes, no weird lights, nothing strange at all. The battery was disconnected all week, and the ECU removed, but all the settings for traction control, ride mode, and quick-shifter remained as they were.

I let it warm up for just a few minutes. (130 degrees F}

I can detect some sort of adjustment to the fueling or timing at idle.  It has a very slight difference in cadence.
Rolling out in B mode, I can immediately feel the the B mode jerkiness is now more pronounced.  Not even a slight lull in responsiveness to throtttle inputs off idle.  Kind of like a carbureted bike with zero slack, or even a small amount of preload in the throttle cable.

Through the rev range, responsiveness is the most noticeable change. The revs very quickly change to match whatever throttle position you choose. This is true both opening and closing the throttle.

Power.  This is where I didn't really know what to expect.  After all, the bike was fast right from the showroom floor.  Really fast.  Would 10 or 12 or even 14 extra horsepower make a huge difference?

The answer is yes, but not in the way you might expect. 
The wheelies that we all do because we can and they're silly fun? They now happen sooner and more often. Almost like adding a tooth or two to the rear sprocket. The lack of throttle restriction below 8k RPM is part of it, but the additional power is obvious.  But, it's not "in your face" whacky, Bultaco MX style, crossbar to the mouth delivery, it just offers more than before, the revs climb smoother than before, and quicker than before.  

I would like to take an extended high-RPM romp, but even first gear near redline is far exceeding non-freeway speed limits. From a streetable perspective, I can attest to the fact that the ECU flash will make your stock FZ-10 much more crisp and responsive to throttle inputs, as well as more powerful from idle to redline. 

I still need to evaluate a and b ride modes. Maybe when I get old!

Nothing mechanical except for the O2 sensor removal.  

I have just a few things.
Blaster-X programmable tail light.
Vagabond fender eliminator.
Proton 500 front turn signals.
CRG Arrow mirrors
SC seat (and a Yamaha Comfort seat.)

and now an ECU tune. 

Nice write up. My ECU is heading off to WA next week.

Oddly enough, my band Superluminal Velocity has a song titled Cruise Control.

Just received my ECU back from 2WDW and all I can say is wow, there is a very noticeable difference.

1. Service: Nels was professional and very quick to respond with any questions I had concerning the flash and shipping process. I shipped out my ECU 2-Day air from Florida on Monday to be delivered on Wednesday and he had it back to me by 12:00 noon on Saturday.Fast Service, considering I live on the opposite side of the US.

2. Mods: I have removed the EXUP, AIS and 02 Sensors and installed the Dan-Moto Stainless Cat-Delete pipe. They were able to clear any trouble codes on the ECU from removing those systems and disable them so no codes would be thrown from the mods in the future.

3. Power: Wow, the increase in low-end torque is very clear and makes the FZ-10 more fun to ride in general. Before, when cruising at 40 mph I would keep the bike in 4th gear as any higher gear would cause the engine to have very little response and bog down under load. Now I can cruise in 6th gear at the same speeds and the engine has much better response and doesn't feel overloaded AT ALL. Torque Is felt much, much sooner and more throughout the rev range. "B" mode for whatever reason does not feel nearly as jerky as before because before this flash I refused to even use "B" mode but now it is my favorite. Wheelies happen sooner and smoother as said before and power continues to climb faster all the way to red-line.

I'm not sure exactly what they adjust to help with throttle response in accordance with the "Ride-by-Wire" system but damn does it work. The throttle is very responsive but not snatchy when rolling on or letting off the throttle like before. The bike does not feel restricted at all now and I highly recommend that EVERYONE have this done to their FZ-10 regardless of your riding style. It is clear that the flash improves performance across the board and would yield better torque when loading luggage or another passenger onto the bike as well. 1000% recommended

THANKS NELS!

This is where your ass dyno will notice a large increase of response and power with the Flash and Cat-Delete

Yes I received it today and he did mention he was in California earlier this week. I didn't get any tracking info via email but it showed up today like he said it would!

I'm impressed with the level
Of service since Nels has been out of the office with a serious injury, but no drop off in service! These guys rock!

Didn't mean to click send yet on that last message. Nels has the best customer service I have ever experienced. Took time out of his busy day to answer all my questions before I had even bought anything. And my bike is a completely different bike now.. between the flash and the autoblipper I am amazed, and if anyone is on the fence about it I would highly recommend it

Alright, I'm sending my ecu off this week. I have a question for those of you who have done this already. Do I still need to have a Servo Buddy since the reflash removes the exup? I'm trying to avoid squandering money I don't have to.
