Default Engine code help !

Heys fellow riders ....I have 2012 RG and recently added a Thunder Max performance module . Having a lil trouble here too I must say . I have added my new 02 sensors and wired and have my laptop hooked up to it as I type this and not REAL sure I know what all I'm doing . I have , I think , loaded up the best map for my bike and I show an check engine light on my speedo . The code I have is a P2128 TGS2 . I understand it means P2128 TGS2 High but that tells me nothing really . I use the Thundermax program to clear the code and the light comes right back on . )(*&^%$#@!&*^%$#@

Not real good support that I got over the phone , 1st time , on helping a novice computer installer on my bike . Any help would be greatly appreciated !

Anyone here that might be kind enough and knowledgeable enough to help me get back running stronger than ever , your welcome to call me . IM for any help or for my phone number .

Thanks again in advance !

Danny

TGS Twist Grip Sensor..... it does not like something with your Throttle By Wire system.

you have to figure out if it is the grip sensor or the one on the throttle body... check for clean tight connections all over

I pulled my THundermax because it was not playing ice with MY bike (everyone else I know that has one it works the ballz!) but you might want to go back and read the initialize procedure again

IIRC there is a on off on off on sequence that gets the module to read all the sensors and self calibrate.

It may help you to try that

Thanks guys ...I'll check my connectors . It worked fine with the stock Harley module though . Tech says that Thundermax will pickup so much more than the stock pc does .
It does make sense since my hand throttle is sluggish to the Thundermax system and max's out the RPM at 3200 RPM's . All I know Is that I'm not happy with my system after paying out nearly 800 dollars for something that was what I thought a plug and ride system and now my bike has been down for a couple weeks with no help from the Thundermax people I bought it from . VERY dishearting !
