I only have stage 1, cat delete with can opener baffle & stock muffler. The very bottom end (taking off) lags for about 1 second (maybe less, haven’t timed it) then it comes alive & boils the tire off. Without the baffle & straight shot muffler the delay was much greater & more noticeable. That was both tested from dead stopped to WOT. Just my experience.

It has taken about 250 miles for me to get all the mapping changes working. It's not just the ECU receiving information and adjusting, I have to adjust my driving and shifting style.
Stage 1 has about the same hp and torque as stage 2 until about 6,500 then the dyno graphs start to separate. You have to be a seasoned rider to really feel the difference.
So, Stage 1 will put a smile on your face just fine with only a slight change in sound.

Hi Dennis,
I just received back my ECU from Monster (not even put it back on the Spyder yet) and was surprised about the dimension of the holes in the air box lid. Just never realize how 2 holes of 35mm might be big
On your experience, is there any precaution to take regarding dust or water that might comes in ?
I know that I should be careful when washing it but I guess that riding in rain should not be a problem ?
Thanks

looks like to me if you get water in there you tried really hard dust no problem the hoes outside of filter

Monster Fuel Injection - another happy customer :)
Results !!!
I finally sent my ECU to Monster Fuel Injection for a stage 2 tune.
I reinstalled my ECU and Air filter lid yesterday and took a small test drive with it. Only about 40km.
As everyone says, it's really a good difference. No more hesitation when twisting the handle and just a good acceleration feeling.
you can fell that the torq is now all along the revolution and not just in high rev like before.
And regarding my concern about more noise coming from the air box holes, I can say that if there's a difference, I can barely hear it.
So far, I'm very happy that I finally got it done !

I just got mine back from upgrading from Stage 1 to Stage 2 and I emphasize Upgrade!
Though I was somewhat happy with the Stage 1, I did find that my Spyder (2014 RT-Ltd) ran rough & jerky on take off when it was cold.
I couldn't wipe the smile off my face after taking it for a rip after installing the ECU with the Stage 2 flash.
The Spyder runs sooo smooth and the throttle response just couldn't be better!!!
Some have mentioned that the addition of the 2 air holes added to the airbox lid was noisy, to be honest I never noticed any increase in volume. The test ride was with stock cat & muffle. (Cat Delete pipe is on the work bench ready to install)

They have my wifes for her rt Getting stage one Also sent mine back up to get stage two for my f3

Today I decided I had to try the Monster stage 2 in combination with cat and stock muffler (= original stock factory setup) and I was truly surprised when I took the Spyder for a spin and realized it had just about the same performance but without the annoying and very loud exhaust note I had with the cat delete! ��
It really is a lot more enjoying to drive when not disturbing the neighbors or having to wear ear protection anymore. Especially since the performance is still very good '
That's why the stage II is a better all around choice...you get more low to mid range performance...also...you have a better selection of exhaust to choose from without a loss of performance.

This is good to hear. I am looking to upgrade my F3T with more power. I want the most tq. and hp. that I can get without being too loud. Right now I am 100% stock, but I just need a good direction to go. Don't want anything too loud, but do want as much umph as possible.

I just have akrapovic exhaust with no ecu flash and original cat. Thinking of going with RLS cat delete and stage 1 flash and than compare stock exhaust with akrapovic.

Okay....strong bit of advice ...before you do anything pertaining to your exhaust, do your map first...then look into the exhaust.

So you are saying ECU flash before cat delete / exhaust?

Yes...do the ECU flash first.

I would do the cat delete & flash at the same time. Just my opinion (learned from experiences)

That sounds strange. So are you saying that if you do the ECU remap, the computer will pick up the exhaust changes and make the appropriate changes? I actually thought you would need to give your bike specs before getting the ECU tune. Inquiring minds want to know.

You can do it either way..but ..I wouldn't do so due to the fact of your motor running too lean because you're getting more air and not fuel...because you changed your exhaust...I agree with js535..the best way is to do them both at the same time...but if you're on a budget..do the flash first. that way you're not running lean prior to installing the map...my mechanic gave me this advice...

I verified the same experience. I went back to all stock exhaust and was hard pressed to notice any power loss. Owning two ECUs, stage 1 and stage 2, I went back to stage 1 ECU flash, covered the holes in the filter cover that stage 2 required. I'm getting older, but I like the quiet exhaust of stock and have basically no power loss. There is a definite honking intake noise when the holes are open on the top of the air filter that is a modification requirement for stage 2 flash.
Stage 2 flash has a noticeable power advantage that really kicks in above 7,000 rpm. But with all the new lower power the flash delivers down low, I just don't rev that high anymore.
So just to confirm other posts, it DOES NOT MATTER which flash or which combination of exhaust, our Spyders adjust to all combinations.
Just wanted to share

BTW, I am willing to part with my RLS delete and Spyder 1 Stainless exhaust. I have over $1,000 invested in my set up. It has a combination of three in line baffles. It can be reasonably quiet when need be, and has a good bark when you get on the power. $300 plus shipping OBO. PM me if interested for pics. This is a flashy set up of stainless and Chrome. Only fits RT, F3L and F3T.

I currently have the cat delete with baffle & stock muffler, and stage 1. With the new mods I did (F3ST) it’s actually louder in my helmet. I think the exhaust echos off the ground & my windshield which I’m right in the middle of. I would really like to try a T or L muffler on mine to see how it sounds. I thought I was going to get away from running ear buds & just use helmet speakers but no such luck.

Hello, wanting to do this ecu mod. But have a few questions. How do tell if you have Generation 1 or 2, or other, with regards to the Rev limiter? And the mod for the air box, is that to make room for a modded ecm stage 2, or just air flow?

Wildrice I too have the stage 2 remap with RLS Cat Delete with two additional baffles on a F3-S Daytona. This thing pulls like a rocket. However off the line absolutely NO tire spin. I had considered putting my Cat back on. Just to see if it is a back pressure issue.
-
What exactly is the cat delete and what does it do for you
-
Interested in how yours performs with the stock cat back on. I have a Daytona also with just the Akrapovic Sinister pipe. Am I running lean with no tune?No bark off the line but it picks up fast. I was expecting more off the line snap. Are you saying the stage 2 didnt help or could it be the baffles you're running? I'm considering the stage 2 and RLS cat delete.
