Aside from a potential spike when it spools up.
That is a hp vs torque graph
A boost graph would be more informative
is that boost spike possibly down to running too much boost so actuator can not handle it? hence it spikes then settles down or am i way of the mark. if i was to run on low boost will this be fine to run or will it need a remap to be safe? - or as you say does the graph not really show us much? - no boost graph : ecu link g4, uprated turbo unknown, manifold uprated. ? And see it on a gauge when driving?jimGTS wrote:Boost spikes usually down to incorrect boost controller settings.
Gain is to high bringing in boost too quickly.
Without a boost graph no one can confirm what's going after this initial spool up area, you'd expect to see a spike in torque when you have a spike in boost.
Can you feel this spike
An electronic boost controller tweak should be able to fix this without any need for a remap.
All depends if you can feel it and it's a problem for you?
.... but there was a peak setting stored that indicated a spike ... will go and have a play with the gain settings on the controller. the low boost setting gain was significantly lower than on high boost .... likely upped to get the magic 400 torque figure? if i turn the boost down will this eliminate the possibility ? eg) shout up to say 1.35 bar then settle around 1.2?adamshaw wrote:
to see a spike on the controller would it usuall shoot up and then settle around a standard figure.
..i will reduce the gain on high boost to get a smoother delivery which should hopefully eliminate the spike should be 1.6 bar. .... i dont feel it when i drive .... would i know if it was spiking? would i feel the boost suddly drop off / pull back ? would it be obvious when driving? it may be someone already sorted the ebc before me? so you would loose/feel torque drop off in that small area.jimGTS wrote:you should be able to feel a boost spike.
car will pull like crazy and die back down almost immediately once boost levels off.
which makes sense given the look of your torque graph.
eg, shoots to 1.6bar, back down to 1.4,
levelling off the boost gain will im sure mean a smoother torque/power delivery.
... i will keep you posted. i think since the RR someone as tweaked the settings as it seemssmooth now. set gain 0.13 warning 1.2. reduction 15% set gain 0.2 warning 1.6 reduction 5% - should gain be higher on hi boost ? this is on a greddy prospec b ebc? 
jimGTS wrote:you must be missing some settings there?
greddy ebc i thought had, set, gain and set gain.
your set gain seems very low, which i guess is not a bad thing.
your gain is pretty low also already, so again, i wouldnt expect to see spikes.
if you cant feel anything on the road, perhaps it got tweaked already?
you really need to watch the ebc/boost gauge to see whats happening.
then gain is 10. set gain 0.13. (greddy ebc hooked into the link?), then id guess the same timing/fueling will be used on all boost settings to a certain degree (boost pressure is feed to fuel pressure reg so it will add in more fuel more boost it sees anyways). shouldnt cause any harm.jimGTS wrote:yes the set gain should be about 4psi less than the desired boost.
least those were the greddy settings i saw suggested a long time ago.
unless you have maps based on boost pressure
turning ebc off will run actuator pressure, and likely quite rich on boost id guess.
... its the set gain which is really low on both so this must be incorrect ? 
'00 Honda CBR600 Follow me on Instagram @c35rob..will got to 1.4 so i need to increase set and perhaps start with set gain at 0.2 ... 20kpa and work up from there ? back down to 0.13kpa and woosh turbo kicks in strong
