The sensor in the intake could cause a major problem and it is called a T-MAP sensor, if it gets contaminated with oil from the air intake it will give false readings to the computer, It monitors air intake temp and barometric pressure for altitude and tells how much fuel to provide the engine, It could cause problems if it gets oil in it, You need to remember that your ECM only monitors the intake for the fuel calculation as well the TBS sensor so what happens after it is not monitored and would not see a lean condition, if the intake says it is all good on its end, it passes the buck at that point with nothing watching the after math, The only way the engine knows there is a lean condition after the combustion system is the o2 sensor looking for what is coming out of the exhaust and it would not no a lean condition at this point without a o2 sensor, these ECU do not do that, they are not that smart, When you make intake and exhaust changes you need to do it the old way buy seeing what the plugs are doing or the new way use a gas analyzer to see how thing are burning, On any dirt bike if you put a exhaust on them you need to add more fuel for it by changing to a bigger jet size, that is what the fuel modules do, Your code 25 is a transmission input:invalid gear code and that needs to be looked at also, My guess at this point would be a faulty T-map sensor due to oil contamination from the air cleaner, But that is a guess not being there to look at it my self. :?: .

No problem. I try to check the site twice a day unless I am out camping.

This was the first i have heard of them but this is what i found out, the product is made overseas and they had some problems with a cdi made for the DS650, here is that link http://forums.atvconnection.com/message … 460265.cfm

This is a very new and un-tested box even stateing it was re designned. till it gets a better name out there and i hear more about it i would not use it in my ranger, I am also very leary about there claims of 20% gain. I need to see Dyno numbers for that claim of 10 Hp.  :idea:  :!: .

If you own a ranger XP 2005 to 2006 The ECU of choice is the one from a sportsman 700 efi atv, The 2005 and 2006 rangers are detuned to the 40 horse power level from 45HP due to cam and ecu calibrations, the 2007 runs a different cam and ecu. It will run the sp ecu but need to run the sportsman cam or one of the aftermarket cams but will still lose the rear end unlock, The ECU part number is 4011560, You can use a sportsman 800 ECU but will cause you to over fuel the engine without a EFI controller like the one from power commander or boondocker, The 700 sp ecu will work well all the way to a moderate level of modification, If you have a 2007 and latter Polaris you need to look at the ones from dirtydawg and mountain performance but remember they will not do much on a stock or near stock machine, Will help a lot on a well modified machine with a cam and exhaust. :idea:  :!: .

Grant check out the posting I put on OEM parts on this site, I think the site is  www.polarispartshouse.com

I am also glad to see that it finally came together for you .

I will do a little looking into this and see what happens .
