Pinit Racing / Best Dual Sport Bikes Performance ECM
I perused the websites and watched many of the vids offered.
It seems both companies are one in the same.
They have successfully penetrated the KLX ECM and are CURRENTLY IN PROCESS of revealing more and more of the internal tables.
As they learn of the internal processes and tables, they are improving their ability to reprogram our ECM's.
As of this writing, they have found the table that controls the secondary throttle valve, and have defeated most, perhaps all, of it's deleterious affects on power production.
I say "most" because the power curve on this latest vid still has a dip in the upper RPM area AND he says they are still working on the reprogramming.
So, at this point in their efforts, removal of the secondary throttle plate is no longer necessary.
I would advise that we all wait until they announce the final iteration of their reprogramming efforts before purchasing their ECM.
There are indications that they grasp, and understand, the knowledge necessary in order to produce top performance programming - such as fully evaluating stock fueling and ignition schemes in order to determine "avenues of attack", using correct AFR targets for performance refueling, and the fact that they found the need of a "big front end" ignition curve revamp that allows significant TRQ ramp-up improvements when snapping WOT from lower RPM's ( or they read my ignition tuning project thread...lol)
However, there are also indications that they are "religious zealots" , adhering to a unwise tenet come hell or high water. This is evident in their entire performance offerings. They will not "fully uncork" a exhaust or intake tract. They will only reprogram for "slightly enhanced" induction and exhaust tracts.
We know the KLX's can only achieve top performance production when the airbox lid is removed and a full performance exhaust system is installed - at this point, it seems Pinit Racing will not provide an ECM for such "top performance potential" mod combos.
Also, it is very unfortunate for us that, while they offer products that slightly improve airflow on KTM products, they ( at least currently) want us to destroy our silencers (which also melt our side panels), and destroy our airboxes, with childish "butchering" . Note that they do not advocate for such destruction of KTM parts.
I remain hopeful that they will someday offer us an acceptable "power up kit" as they do with the KTM bikes.

Currently, Pinit Racing is only able to create 26 hp KLX's - which we can easily achieve as well.
However, they certainly seem capable of creating truly high performance KLX's - perhaps approaching 30 hp..
But, for 28+ hp, they are going to have to bolt on a Barker exhaust and run the airbox lidless.

At time of this writing, this is his latest results from his latest reprogramming efforts - note that secondary throttle valve removal is no longer prescribed - and should not be done.

It seems odd that Pinit/BDSB isn't willing to test the Delkevic exhaust system. You'd think if, as he claims, there isn't much of a deference between his modified stock exhaust and the Delkevic he'd want to show that as it will help push people to purchase his ECU reprogramming service instead of a pipe, especially if they can only afford to do one of the two.
Well, a few points:
Under no circumstances should anyone destroy their silencer and airbox PERIOD.
Also, It is not necessary to butcher those components as his butchering does NOT significantly alter/improve airflow - meaning that his ecm will work just as well on stock components.
Fully uncorking induction and exhaust seems to violate his belief system - Any results that are contrary to what we already know - regarding silencer and lidless airbox power potential - would be suspect and disregarded.
He is currently only making 26hp. This is easily achievable by "regular means".

I've already done a stp removal should i buy a BDSB/Pinit Racing ECM and put my 02 sensor back in and run lidless?
Should I take my power commander off and run my 02 sensor again.
I feel like based on my black tinted turn signal I am running rich. Seems like it is in the mid range. No one really does dyno that I'm aware near me. Just trying to get the most. I think The next logical step is more air .
I saw you mentioned someone else has a decent map for powercommander. Anyone have a link for lidless stp removed and exhaust no mid pipe ? I feel like we could be in the 30+ range with these bikes with the timing set propper but just haven't seen it yet.
O2 sensors should NEVER be disconnected or deactivated. They are critical in properly fueling the engine during all "normal" operations ( Closed loops ops ) .
At this time, the best mod progression, with "bang for buck" being the only metric, for the newer EFI bikes, is as follows:
1. Remove the Secondary throttle valve and optionally perform the MCM. Evaluate the new performance.
2. If more power is wanted, install the BDSB ECU or the ECU sold by TSC. Evaluate the new performance.
3. If more power is wanted, going the next level is just as dramatic as the above increases, but the complexity and expense are much greater. A dyno shop and a dyno tune is required. So, if such is not available, there is no need to read further.
A). Lidless airbox, Barker full exhaust with O2 bung, PCFC or EJK fueler
B). Dyno shop tune the open loop operations ONLY. Target the fueling, for open loop ops, to stay between 12.6 - 12.8 .
Enjoy 30+ hp and if done, biggy MCM torque as well.

I guess i need to get my bike to the dyno. I went lidless last night and the power increase was pretty noticeable. I've been running o2 delete 6k miles.
I can definitely tell the bike was struggling for air the power is much more linear and doesn't drop off near 7k rpm.
is the aftermarkrt ecu upgrade really necessary or worth it with mcm mod and a tune?
And is the mcm mod needed with the timing advance the aftermarket ecm provides.
if I am going to the dyno I need to have my proper parts installed. Also thank you klxster I've followed your posts since my first 2009 klx in 2013.
