I just returned from a couple days in Revy that were both cut short due to issues with my sled. Prior to this trip, I had just over 500 trouble free miles on this sled with respect to the motor/turbo. I did have an issue with my overstructure (both front and rear) which was replaced under warranty. Following this warranty work, I did have two rides without issue before heading to Revy.
Day one, hit the 30+km's of trail into Area 51, sled ran fine though I was never much past 1/2 throttle as the trail was pretty whooped out. Did a few climbs above the old cabin and sled seemed fine, just a bit boggy in top end, figure its something to due with the amount of snow covering thee hood/intakes. After a lunch break, hit same hill and sled does a big bog when when I hit it wide open, RPM's drop down to 6000 instantly. Check primary spring, plugs, all the easy on hill stuff, but it does it all the time now whenever I give it some throttle. Turbo is spooling, idles fine, runs great until it needs to be stepped on. Have it set at about 8 lbs at the cabin. Don't feel like having my sled stranded this far from truck so call it a day and head back to town.
Day two, checked all hoses and plugs that I could reasonably get at with hood and panels off, looked for kinks in boost line from intercooler to control box, all looks good. Decided to give it another try into Sale. Again, mostly 50-60% throttle to start so no issue, running good, as snow gets much deeper and start giving it more throttle, issue comes back. I did some testing and reviewed the MAX data on control box. Box is set at about 7 lbs and I seem to be able to build to about 6.4 before bog hits but now I notice that the AUX injectors showing zero fuel on the stats screen. I turned boost up to see if I could get them to show a reading and pin it till bog hits again but box continues to show zero for the AUX and about 70-74 for the stock injectors. Figure there's not much I can do on the hill and call it a trip.
My first thought was that the injectors are pooched but I would think the control box would still be trying to send fuel to them, even if they where plugged and still show a reading on the box. Tonight, I will look over all lines, tubes, cables, connnections, etc. but I have kind of already done this with no success. Where else should I be looking/testing that could have this type of result? My only other thought is that the control box is faulty. Any suggestions appreciated.
