Just got back from a ride after installing the XIED on my 08EGC. \\;\\\\\\; The bike seems to run better and had areading of 291 deg at the rear cylinder near the spark plug when checked by a IR thermometer.  \\;\\\\\\;I bought the thermometer after the install so I don’t have a baseline. \\;\\\\\\; Do you think  \\;\\\\\\;291 is better than stock. By the way it is 90+ deg today.
291 is a great temp. \\;\\\\\\; There is a huge difference between cylinder temps and actual oil temps. \\;\\\\\\; Your bike is running much cooler than a stock 08. \\;\\\\\\; I measured my buddy's stock 05 Low Rider and his temps were higher than yours. \\;\\\\\\; 05s did not have the heat issues the 07s and 08s have. \\;\\\\\\; J.B.

I get temps of just over 300 on mine with the Powercommander..
AISTQM............ \\; Those are nice numbers, \\; Ive got a set of the XIED comming next week , \\; been running the first generation IED's when they first came out, \\; in fact I only paid $59.00 for the set, \\;they work pretty well, but Im going with ture duals, more for the sound and the clean look, hopefully I can get away without any down loads, \\; \\; We will see...

Thanks for the replies but here is the next issue. \\; I'm throwing P131 and P151 codes. \\; No check engine light. \\; Can I just ignore the codes or is it something that can damage anything.
Those codes are for lean conditions in both cylinders. \\; My guess is that they've been there before the XIEDs. \\; I've read a stock bike can set off the codes. \\; I would clear them and see if they come back on. \\; If they do then I would either call Steve at Nightrider or put back on your stock airbox if your running an upgraded one. \\; If you're already running a stock airbox then I'd be suprised if the codes come back. \\; With the temps that you have you're definetely not running lean or at least not hot. \\; I had the XIEDs on my Dyna, but it ran too lean with a 2-1 and upgraded airkit, so I put back on my PCIII. \\; I did try the XIEDs with the stock airbox and it ran great, but I wanted the performance of the 2-1. \\; J.B.
When any O2 sensor code is set, the ECM will switch to \\;open loop control on the offending cylinder and the XIED will be doing zero. \\;
 \\;
The cylinder isn't actually running lean. \\; The ECM is \\;trying to integrate the average O2 sensor \\;voltage \\;up to the Bias setting (500-600 mV). \\; If the O2 sensor is hot, \\;its max voltage will be around 800 \\;mV. \\; Depending on how \\;much \\;voltage the XIED offsets, it may be possible that the ECM cannot acheive the desired Bias setting. \\; \\;The ECM adds fuel until the integration limit, which is hard coded in the ECM. \\; Once the integration limit is reached, the ECM sets the code.
 \\;
My opinion...It will be common to set these codes with the XIED. \\;
