Initial test of Monster Fuel ECM upgrade

[Wildrice]

Noticing a surging of power at 7500-7800 in 5th

Your first and second gear improvements are more from restoring the back pressure that the primary cat and muffler give. Still, glad you are pleased and I hope mine turns around but I don't hold much hope as it should all have been there from the get go according to Steve.... Except for the "fine tuning" that does happen as you amass more miles.....

I don't recall this lack of acceleration beyond the 7500 rpm in 5th gear earlier. 1st thru 4th pull strong. 5th gear around 107-110 mph felt I was buffeting wind on the wind shield--took a while from 7500-7800 in 5th until traffic forced me to back off. I hadn't really noticed this before but my freeway is traffic limited--getting more congested. Still haven't been able use 6th gear in the top end. I gotta find a new test area:doorag:. Big windshield, passenger backrest, & saddle bags don't help my top end. What ever happened to the guys that claimed 130 mph?

Seems that the CAT delete pipe without any baffle hurts low end torque. I took the CAT delete pipe off and put the CAT/Muffler back on. I could not believe the difference that the OEM set-up has in performance over the CAT Delete. Most people the first thing they do to there new bike is change the muffler system. The OEM muffler system for the most part is already perfectly tuned for the best performance. Removing it just to get more noise.


I can not wait to try the Monster re-map. I will be ordering when the Snow flies..

Something dawned on me that with more miles on the ECU it's not just the ECU learning but the driver learning the flashed ECU shift points as well. I led a group of about a dozen mixed cycles today and at EVERY STOP they talked about how some things I was doing was giving them fits to match. I have learned where my cornering and acceleration advantages and limitations are. I lined up with a FAST rider on an FZ09 and told him to let me start first. I laid down about 25' of perfect starting rubber and nutted the 2nd and 3rd gear shifts at 8,600 rpm and had a big lead up to about 90 mph. He caught me but the road I selected didn't allow him enough room to pass before the next corner. He thinks I'm just about as fast as him but little did he know he was about to toast me if the road was straighter a little longer as I was quickly running out of steam.
What exhaust pipe are you using? Ackrpovic right? You shouldn't need the Thunder Baffle with an Akra.



Dennis--out accelerating a Yamaha FZ09 to 90 mph is awesome--I would have thought he'd be even with you at 50mph. I've had mixed thoughts on using the Big City Thunder Baffle with the Cat & Akrapovic straight shot silencer. It just may reduce my top end performance. Looking at the BCT baffle in the exhaust pipe it looked like minimal air could escape via the exhaust. I really hate taking those 3 springs off/on even with Doc's wire connector. I may need to fabricate a spring hook with a heavy bar for leverage--otherwise I'm stuck pulling the spring when no one else is around to guide the spring hook to the Cat. Anyone have a photo of the device their using to hook up the 3 springs??

I used my brake tools to leverage over the springs worked very well reinstalling the header springs.

Chris, you have absolutely right. I tried the cat delete on my F3 with Thunder Baffle and after two weeks I come back to OEM setup-up. I saw instantly the difference. The low end torque was come back. The monster re-map will be done soon.

Does this increase too speed? you

Gonna start a new thread on this but in case someone stumbles into this one I thought I would link to an update I made in another thread:

I have a 2013 RSS that is rated at 100hp @ 7500RPM with Two Brothers exhaust. It sounds like even though I keep the stock RPM limit that I may get up to 125HP. I have been to the Monster Fuel Injection web site and they show instructions for ECU removal for the 1300 but not the 998. Does anyone have instructions for that?

Time & light rain weather limited my testing to 1st & 2nd gear. I would give it a 25% increase in power to the the new 8600 rpm redline. There is a definite increase in power. 25% increase for approx $400 including freight is a really good deal. I've spent $1900 to go from 170 rwhp to 190 rwhp on my 1st hayabusa. Over $10K + on my turbo hayabusa. Brisk would be my definition of upgraded ECM acceleration. Everything else other than new 8600 rpm redline & improved acceleration appear to have remained the same. More info to follow with time & weather permitting.

Will it help me out run a Corvette for more than 10 feet?

I ask this as I pulled up to a Vette today and we had some quick fun :yes:

Of coarse he blew me away in like 15 feet.

Yeah, there’s no way a jogger can keep up with a Vette, triker .
