Attitude logic box ?

[reed4rmk]

I have a 07 Apex with the boondocker GT25 setup professionally installed. Only a couple 100 miles on the system and have been running it at 7-8 lbs of boost with 50/50 race fuel at about 5000'. I was climbing some hills and it was running great, turned up the boost to around 10 lbs. Went to climb the hill and as soon as the turbo started to spool up it would totally crap out...popping, sputtering, no power. Stopped and turned the boost all the way down and made another run at the hill...same thing as soon as it hit boost. Even on a flat trail, right at about 6-7000 rpm with turbo just kicking in would do the same thing. Below that rpm it ran and idled fine. My Innovate 02 gauge bit the dust and wasn't working..(constant E5) so I couldn't monitor that. As I fiddled with it on the way back to the truck I found that on my Logic box at every mode the fuel had been completly leaned out. By adjusting Mode 4,5 and 6 as rich as it would go it started running pretty decent. My question is: Does the Logic box ever reset itself? Should I have to set it at full rich to get it to run on boost? Is it defective? The only change I made was to turn it from 8# up to 10#. I know this is kind of wordy but some of you smarter guys seem to like details. Thanks for your help!

i would check to see if you blow your throttle bodies off the motor, and check for air leaks, sounds like your problem. take the spacers out of the clamps and clean the grease off the boots, and then glue them

If all the T/b are on and you have no air leaks at the cooler I would think your pl box is junk did you get the update this year for the box? I have a spare that I carry And I think most of the canadians carry a spare to

Thanks, I take a look at the TB's, and check to see if the box has the updates.

Sounds exactly like what we experienced when we took our turbo sleds out for the fist time. In both cases under boost a hose popped off, in one case just after the turbo, in another case at the carbs on an RX1.

What you have described is exactly what happened to us. Really look things over for a hose that may have popped off or split or possibly even a crack in your exhaust prior to the turbo.

We had one sled we were riding with one day develope an exhaust leak prior to the turbo that eventually got so bad it had similar symptoms.

Hope this helps.
