12/13 WR450 Comp ECU Maps?

43 posts in this topic

Ok guys, I’m switching from red to blue and am looking at the 12/13 WR450F and have a few questions. Is the comp ECU plug and play or do you need to install a map to it? The first thing I plan on doing is putting a pipe on and opening up the air box. My buddy just got a 12 WR450 and bought the tuner so I have access to a tuner and can install maps if it is necessary. I was hoping I could just uncork and put the comp ECU on and that would be enough. If you have to install a map to make it work, does anyone have the setting for some good maps?[/size][/font]

It's plug and play until you start changing exhausts systems, etc. So if all you're doing is the typical throttle screw replacement and taking the exhaust restrictor out then you're good to go.

So if an aftermarket pipe goes on, how will that effect a map designed for the stock pipe?

I'm running the FMF map with a twist. I've set the fuel map per spec sheet but I ended up removing the ignition advance due to the power being too snappy off the bottom. It's just about perfect now.

I would imagine the bike would run leaner as the air flow has improved (well hopefully it improves lol). Would it run and be OK? More than likely yes, but it might be worth to get the tune checked.

I have been running the FMF map and so far have nothing bad to say about it. I haven't ridden any real technical single track though.

Google fuel maps for yamaha gytr tuner and pick the first link on the results page. There you will see a link to suggested baseline settings for yz or wr.

I got to ride my buddy’s 12WR450 this weekend and WOW! Love it!. He got the comp ecu in and a 2008 YZ pipe on. The suspension was great on the trail. The bike is a beast down low on the trails. It had more snap than his 09YZ 450! He is going to have to retard the timing down low. He has the tuner but forgot to pack it so we couldn’t play with the setting this weekend. I can’t wait to get mine just need to sale my bike now.

Good job RSWR450F! I found some maps for the YZ450F to tame it down in the woods that might work good for the WR. I've got about 6 pages of maps I'm going to try out this weekend and I post the results here later.

Has anybody worked out a custom map for tight, rocky, multi stepped singletrack? I was in Moab last week and the FMF exhaust map i was running was no bueno. A lot of the trails were 5 mph trails with multi level stair steps and this bike is a beast to manage at that speed. The FMF map is too agressive when going slow (at least for me) and needing to delicately add power to take the weight off the front, etc.

My bike has airbox mod, comp ECU and FMF Can only (stock head pipe)

The bike is fine in the desert or on 2 tracks with the FMF map, just need something now for the technical stuff. The majority of the published maps seem to be for a stock exhaust. I guess I could interprolate between the two???

what say you experts?

thx

I have the SAME set up coming for my 2012 WR450F. (Air Box done, ECU/Programmer and CGYTR PowerCore ordered)

Same question as above... and also any recommendations to boot the stock header in favor for a PowerBomb? ?
