upgrading Te250 with power commander to the new 12 hole injector

I own a TE 250 2010 model with POWER COMMANDER (took off all the non relevant components)
i still have no power in low Revs,
I want to upgrade the injector to 12 holes (8000H7563)
should i use the POWER COMMANDER after the upgrade?
any one did the upgrade with the injector and the power commander?

where is the best place to buy the 12 hole injector kit (8000H7563)?

I have the same bike tuned with I-beat 4pt injector and it runs great.

The kit is $400.

what settings did you use with I-beat? how did you do the programming? I would like to do the same on mine..

Well I won both a 2010 Te250 with a 4 pt injector and a 2012 TXC310 with the 12 pt injector.

The 12 pt is definitely snappier but the 4pt runs well too. No stalling on either. The 4pt has a more "4 stroke feel" at low rpms.

My TE250 is running 105 107 108 with an open Arrow pipe with no SA.

With the SA it runs 3 less across the board.....102 104 105

what is SA? Spark Arrestor?

If you use SA, and lower them 3 across the board, how does it feel?

Like in a game chance?

Definitely less off the bottom bark with the SA in. A lot less noise too!

The 310 is too snappy with the SA out. Good for MX..not for slimy woods.

what happens if you put in the SA with the same settings you use without SA? how does it feel on the TE?

If your "SA out" settings are a little lean then it may be okay....all you can do it try it.

I find it best to adjust COs for the SA.

i rode the Beehive and experiences some missing and bit of backfire on on-off throttle transtions.

I'm going to increase CO1 and 2 up 2 points a see if it is better.

I put a 12 port injector out of a kx450 I cant remember what year, but it was much cheaper than a husky part

I run the 12 pt with the 2012 ECI on our 2011 TXC. Works excellent.
