problems

[tree climber]

when i hit the gas it sounds like a car does when the lifters float. you know what i mean. like wawawawawawa. im not sure if its the rev limiter im hitting or if something else is screwy. i just cleaned my exhaust valves and put in new springs to be sure that wasnt causing it. it kinda did it when i only hit it part throttle not wide open too

If it comes out of it after a short time, try adding a couple points to the LOW PSI and maybe to the MID PSI.

sounds like a boondocker box. i have attitude

noise

It is probably tripping the knock sensor! Increase your blue green first if that dosent stop it increase your red. What is your O2 gauge or EGT reading? What is it on? What is your fuel pressure? You might have to have your Box reflashed if none of those do it!

i guess it happens so fast i dont get a chance to see where my 02 is at my fuel pressure is 42 my green blue is the stock 6. i was under the impression at first that it was the rev limiter so i was waiting for heavier weights. i still need heavier but now i feel its not the rev limiter. what is the rev limiter on these anyways

Knock sensor

8250 8300 RPMS is what you should be turning. Go ride a straight strech and watch your O2 that is key. If yours is doing what mine did you would get about 3/4 throttle and it would go lean and do what you explained. I had to get Derek from Attitude to reflash my box to make it richer. Crank the blue green up all the way then try it if still does it crank the red all the way up till it falls on its face if it will if not your not getting enough fuel and that is as rich as you can get it with out reflashing the box. Who's kit are you running?

 

[tree climber]

i got a silber kit. im heading to the hills tomorrow. the snow sucks but i have to go so i hope i can get dialed in at least

 

[Jmanwillis]

I have the same turbo set up your going to have to crank those two settings up and then send your box to Derek or Justin and have them reflash it.

 

[tree climber]

oh great. why do they need to be reflashed

 

[brycter]

Do you have a 2010 or a 2009?

 

[tree climber]

its neither. its an 07 d7

 

[Jmanwillis]

It is no big deal the mapping needs to be changed some! It will run with the flash that is in there but the up dated one will get your parameters where they need to be.

 

[tree climber]

well im gonna try it this weekend if not i got a spare i can ride but would rather not. i will send my box to either justin or derek when i get back

 

[tree climber]

took it out today and had boost controller turned all the way down and it was still building 8 pounds and thats when it would start to do it had fuel turned all the way up and was super rich. was gonna try to adjust the preload on the wastegate then broke the clip. not a good day

 

[Jmanwillis]

What was your O2 showing at full throttle? Are you just running pump gas? What elevation are you running? I had to have the Red all the way up and the Blue green and I was around 8500 feet. and it would still bareley get it to not do that and I was runing 50/50 mix 110 I would send your box in for the reflash I would almost bet it will take care of your cutting out problem.

 

[tree climber]

i got the new flash. i hve them both turned all the way up and it is fat as hell until i hit it but it builds boost to about 8 pounds and i am running mostly pump then it starts the cutting

 

[tree climber]

i should add. on my wideband it never gets below 13.5 wide open before it stutters then its in the 15s to 16s

 

[mtnrider]

sounds to me like your fuel filter may be plugged. had a friends sled do the same thing. go lean at full throttle.

 

[Jmanwillis]

If you don't get below 13.5 your not rich your lean! Who did your reflash?

 

[tree climber]

i talked to justin before i went out yesterday and he said my box had the new flash in it
