why was I not given the chance to reflash the ecu like you said?

I dont have my records back that far to know for sure how that ecu was set up.

We both agreed this reflashing the ecu was the only fair way to do it. It is not right to compare a flash not done to your spec to a flash done to your spec.
I decided I wanted to ride and when I found the differences to be minor, I figured I would say so. After all, the bike I got it from was setup exactly like mine. I was hoping your records would indicate that. And after you flash it again, I will again compare, but it will be a lot more in depth than what I put out already. You should be proud of the flash as it is good. especially the B-mode.
I expect that your update will be even better.

the bike you got it set up being exactly like yours is only part of it , like I said before.

I set up the ecu to each of my customers wants, its been one of my things since day 1.

Im glad you liked my original flash but im betting you like the new one thats set up for you even better

This ^ is what makes vcyclenut awesome. You said you probably won't ever use A mode - well you can ask him to make it into something useful for you. Imagine what you might want other than the B and STD modes and write that down.

Although I am way to particular to allow 1/4 turn to get the slack out of the throttle, once the throttle is engaged that slack measurement is irrelevant. That slack is only relevant from 0 throttle until the throttle is than engaged. Once driving the motorcycle I find it rare that my throttle isn't engaged even if it is a little bit therefore the jerky throttle is more to do with fuelling and the ride by wire maps.
I couldn't disagree more. Minimising slack on my throttle cables improved twitchiness noticeably. The reason being that the neural connection between your hand and brain is waiting for a response when twisting the throttle, when it doesn't get it as expected the brain tells the hand to turn more and faster, which is usually too much.
You can see a similar effect with a sticky throttle cable.
I'm not saying it completely removes twitchiness, but it helps.

Here's a thing, why is my throttle response less jerky in A mode when riding fast in the twistys, and less jerky in STD around town? I don't use B mode as it feels too flat.

You're comparing apples to oranges here a bit talking about different modes in different riding applications. Try riding around town only and use A, STD, and B mode. B mode is designed for smooth throttle response in the lower throttle and lower RPMs. A mode is designed for smoother throttle in the higher throttle, higher RPMs. STD mode is a balance of both, this is why A mode feels better in the twisties and STD feels better around town for you. Just imagine A mode is dialed in for 50 - 100% throttle, B mode is dialed in for 0 - 50% and STD mode is dialed for 25 - 75% throttle. I'm exagerating these numbers a bit just to help visualize but each throttle by wire map is designed with a certain range of intended throttle use. If you keep the RPMs higher in A mode you'll find it won't feel as twitchy around town but not too smooth being that you'll be in first gear most of the time lol.

I understand what you're saying about the cable slack but once the wire is in tension cable slack has no relevance. It does however come back into play when it loses tension and you have to find the throttle position when it gains tension again. One of my riding buddies has so much cable slack I can't stand riding his bike for this very reason but it doesn't make his throttle twitchy, it just makes his bike awkard pulling away from dead stop and sometimes when shifting gears.

OK riders, here is an update. I've been very busy and between that and the weather, I have not been able to do the back-to-back rides with both ECUs.
I have been able to ride with both ECU's that were set up for me and my bike. I now don't think it's needed.

I did a throttle body sync and asked my friend to install one of the 2 ECUs. I had been riding with Ivan's ECU flash and I knew right away that the flash I was riding was from VCyclenut.
Both start in the STD mode and both are good, but one is better for me than the other. In this case, VCyclenut offers the superior flash for me.

Why is it better?

1. It's just smoother.
STD - exactly what I wanted. Smooth power like a perfectly jetted set of carbs.
A- The throttle is definitely more aggressive, but I can still manage use it comfortably in 1st gear tight twisty roads.
B- Deceptively good. It will be great in the rain, but you will want to short shift as when the power ramps up, the front wheel will loft.

2. It's less expensive. $100 saves is a $100 saved.

3. David is a pleasure to deal with and he obviously stands behind his services.

Agreed, I can't say enough good stuff about his work and his patience. I don't have anything other than the stock flash to compare it to, but my bike is so smooth and a joy to ride fast. One of these days I'll have to try that Ivan's just out of curiosity.
