Hello From Peterborough

[Nitty Gritty]

Hi Pielight,
Not much change in MPG.
On the standard map fueling is shut off on a closed throttle, so approaching a hair pin on a closed throttle the engine will use up any fuel that is left in the system as it runs on a close throttle to the bend. When you open the throttle, say cranked over in the hair pin, there isn't an immediate response from the engine. With the new map the fueling continues on a close throttle (not running on) so when you ask for power it's immediately there.
On the standard map the bike is over fueled in places through the rev range, the new map adjusts the fueling for optimal settings all through the rev range. This saves some fuel, which makes up for the extra fuel used on a closed throttle. My 2017 has 150 BHP at the back wheel and is as fast as I want prior to the remap so not interested in extra top speed, but the dyno showed a steep straight line up to 142 mph then a more moderate incline for the last 10 mph or so. For me the main benifits have been at slow speed manouvering, U turns, Alpine hair pins when the bikes cranked over and the roads changing altitude by the height of a double decker bus in a few meters, you want a touch of power to keep it upright, no slight delays, the finest of touches on the throttle produces smooth controllable power. Uk riding you mightn't want, need or notice the benifits of a remap, but I'm a bit anul, all the other types - throttle tammer, power commander etc seem to be around the £300 mark (if you allow for knackering the heated grips fitting a throttle tamer), this is the least obvious way to remove the fuel injection lag.

Hi Nitty Gritty. Thanks for taking the time to give such detail....apologies I've not responded sooner...not been on here for a while as it's been manic at both home and work!
I've laid the bike up for the winter so won't get a chance to properly evaluate it for a while. I had noticed the slight throttle lag you describe though. I also have a carb model blackbird whose response is instantaneous and eager, but I'll ride the GTR for a bit to see if I feel the need to address it. These things shouldn't be of concern but tend to be...I'm also a bit anal myself! With this kind of thing, if there was no potential solution you'd not give it another thought, but because there is it niggles away

[Pielight]

the only thing i had as negative was the wind buffering. now a laminar rma x-creen solved that prob too

Looks a good option. Will consider a one myself.

Welcome Paul.

Thanks Gla55y. I see you are from my neck  of the woods (I live in Peterborough now but from Washington/Newcastle.

Yes I'm in Ormesby near to the A174 (Parkway). You will probably have used it to go to Whitby etc.

I've only had the GTR about 6 months but loving it. The ECU map is on my list though as I have noticed the throttle lag.

Passed by many times Mick. Had an Aunt & Uncle who lived in Brid so from the age of 5 spent almost every school holiday there. It took 5 hours from Newcastle by coach back then! This included a stop off at Guisborough. Driven/ridden there countless times too. Once had an extremely close shave with two sheep in the dark travelling at speed on my RD400 many years ago!

Now the seed is planted the ecu map is almost inevitable for me too! There does not seem to be a downside either.
