Hand warmer ecu flash opinions needed

As a nytro newbie I've heard a lot about the less than stellar hand warmer performance. Does the collective think this could be better fix than others like yamaheater? From my point of view it certainly seems more simple and cheaper.

Its a relatively new thing that came into affect last year. I dont think many if any have tried it yet. What did they say about the amount of heat you will get from the update? I would guess most have the Yamaheaters on ... I know I do.
 
hand warmers

if you are just looking for a cheaper alternative, I added Polly handwarmers to my wifes rev and if you leave them on high the hole time your likely to burn a hole through your gloves they get so hot. cost = $30. I have herd nothing but good about the yamaheaters though also, and whats nice about them is they are just plug and play no splicing wiring from what I understand.
 
If I didnt have yamahaheaters on my Nytros already I would sure try it. For $100 that would be a easy clean fix. I do love my yamaheaters though. Shane.

2008-2011 Nytro hand warmer fix: The reason the hand warmers do not work adequately on older Nytro's has nothing to do with the warmers themselves - the problem resides in the ECU programming and how the hand warmers function. We recalibrate the way the ECU handles the power output to the hand warmers which makes them function more effectively like the newer 2012+ models.This flash works on ANY 2008-2011 Nytro $99.00 or $69.00 with any other flash
 
Just to throw my opinion out there. If you haven't rode the Nytro yet to experience the handwarmers, do that first before any mods. When I bought mine I thought I would need to address this issue but found that my handwarmers are more than adequate for my riding and I usually use thin gloves. My bigger issue is I keep breaking mine and needing them replaced under warranty. When they are working though I rarely need them turned up past half. Everyone is different however when it comes to handwarmer preference

I have 16 costumers ECU’s right now that are getting re-flashed right now. All of them have some sort of timing reductions, but every one of them that is 08-11 is also getting the hand warmer re-flash. It works! No needs to re-wire any thing just plug your ECU back in a go ride.
 
Excuse my ignorance but what is everyone talking about with this ecu flash ...if this is a fix for the handwarmers then how do I get it done
 
I got their upgrades for my ecu, timing water and hand warmer, the hand warmers work good only at high rpms, and they said it would work better at idle too, which is not the case (I didn't notice any difference at idle) but It did burn my rsi heating element and odi grip on the left side.

I would like more details as well. First I heard of it.

Here's some info on the Re-flash of your factory Yamaha ECU.

Mountain Performance Inc. (MPI)/ Evolution Powersports is proud to announce a broad range of ECU Programs for the Yamaha Nytro. Our strategic development group has spent the last 3 years perfecting a variety of different OEM ECU software calibrations that are ready to be unleashed on the Yamaha community.

Safety Flash: In this software recalibration, the engine timing is re-calibrated to reduce ignition timing as water temperature increases and the temperature light illuminates 20 deg F sooner than stock (stock 212F, now 190F). The stock parameters are not sensitive enough to protect the engine while under boost. When the stock program turns on the temp light while on boost, the engine may already have been damaged. Our software flash protects the engine by reducing timing as water temperature increases to help safeguard against engine damage. The rider is also alerted by illuminating the water temperature warning light.
Part # HSE-0060 $299 (or $99 when added to 550cc Injector Flash).

Reduced Timing Flash: In this software recalibration, the ignition timing tables are re-mapped to compensate for boosted applications. Ignition timing is gradually reduced as the engines load (throttle position) increases which is essential in eliminating engine detonation. The reduction of ignition timing allows for more boost at any given octane fuel. Example: if OEM programming is safe at 5PSI of boost, this re-map would allow 8PSI of boost while using the same fuel. A second example: Vehicles running race gas to allow a given boost level could now be run with pump premium fuel. It many cases this flash can eliminate the need to run a head shim (and remove all the liabilities of having to disassemble and reassemble the engines cylinder head). A good rule of thumb is that this calibration allows for 2 to 3 more PSI of boost without further engine modification or fuel octane increase.
Part # HSE-0062 $299 (or $99 when added to 550cc Injector Flash).

Safety Flash with reduced timing: In this software recalibration, the safety flash and reduced timing flash are combined to offer the ultimate performance and engine safety package.
Part # HSE-0061 $399 (a $200 savings)

2008-2011 Nytro hand warmer fix: Hand warmers on earlier model Nytros do not get as warm or heat up as fast as the 2012 and later models. This is due to the ECU’s programming and is actually not the warmers themselves. By simply re-flashing the OEM ECU grip warmer performance is greatly enhanced. The recalibration increases power output to the hand warmers which makes them function more effectively. After the re-flash the grips actually get hot while the engine is idling. The increased grip warmer is immediately noticed and appreciated by the driver.
Part # HSE-0066 $99.00 ($79.00 when combined with any other flash package HSE-0067).

550cc Injector Flash (used in conjunction with MPI/Bosch 550cc injectors): This software recalibration replaces the OEM 330cc injectors with 550cc injectors. The 550cc re-flash is used in conjunction with your existing piggyback / auxiliary fuel controller. The 550cc injectors allow for 40% more fuel versus the OEM injectors. The vehicle maintains perfect drivability with 550cc injectors, with no hiccups, glitches, etc. It is widely accepted that supplemental fuels controllers do a great job of managing fuel for boost as long as the OEM 330cc injectors are maintained; unfortunately horsepower is limited by the injector size. With the 550cc re-flash, the OEM computer compensates for the larger injectors leaving the piggyback / auxiliary fuel controller to manage the boost fuel. Property scaled larger fuel injectors are the only way to increase fuel delivery and have an OEM like performing engine – without hesitations, stumbles, etc. The OEM computer contains all the knowledge and strategies for idle, acceleration, deceleration and all other transitional throttle changes. When the OEM injector size is changed, the OEM computer must have all of its tables re-mapped to compensate. If the OEM ECU isn’t remapped, the piggyback / auxiliary fuel controller must constantly try to second guess and correct for transitional changes that are miss-managed by a non-reprogrammed OEM computer. This also eliminates the need for a second set of supplemental injector; an alternate method sometimes used to overcome the 330cc injector limitation. Idle RPM has been increased by 150 RPM, eliminating the need to manually adjust the OEM throttle stop (manually adjusting the throttle stop often results in unexpected idle characteristics because the computer’s ability to electronically control idle has been overridden). This software flash is sold in conjunction with high quality Bosch 550cc injectors, which includes all necessary hardware for direct replacement of the OEM 330cc units.
Part #s HSE-0063 & HSK-1238 $799 (includes injectors and hardware).
Please specify Vehicle Year plus Supercharger or Turbocharger type
 
Had the MPI fix been around when I had my Nytro, I would have gone that route due to cost savings and no need to route all that extra wiring the Yamaheater has (not knocking the Yamaheater, it worked great). Looks like an easy job...remove ECU and send out for reflash.

Matt, was there a reason why this was so long in coming?

Yamaha's ECU isn't the easiest thing to break into.
 
Can you re calibrate the temp light for any temp as a separate package? Say I want my temp light to come on at 200 and a handwarmer flash as well?
