Hey guys, So I got a new to me a boost-it pro, and ever since getting it, I'd get a random det code set, usually before it was say, 1-2 times in a ride and around 6-7k rpm, only happened when i was on off the gas for a second, again all day it only did it once or twice max, I was told to check the TPS adjustment, it was at like .630v so i set it as close to .700v as I could. then it says for the idle adjustment/voltage you set it to 1.800V, I did that, fired sled up and It started easier than before, less of a tug on the pull start for it to fire, however idle was about 2400-2500 rpm so I turned it down to about 2000,. I will contact the boost it guys as well for help and info but I figure'd to post here to see about some ideas and suggestions as well that may help.
for about 1/4 of my ride the sled ran fine, that 1/4 was lower elevation, approx 4300 feet, I can pin the sled and hold it wide open and it will not detonate at all down low, revs at that elevation were about 8200 rpm. But then as the day went on when I pinned it and let off the gas, it would throw the DET code, ONLY when I let off, not while wide open, So I thought thats odd, added some fuel on the control box to ~7500-8250 rpm to see if that helps, I *thought* it helped, but then all the sudden it decided when going wide open it would kind of run then stutter after a second, and make a Puff pop noise and then the DET code would set, It almost was like a back fire but softer toned and not a rpm limiter stutter. I was at 6500 feet pulling 7900 rpm when it was doing that.
I do not have a boost gauge or a/f. But I feel like since this started happening after the tps adjustment and or coincidence..... maybe I have a bad TPS? or maybe something else is going on? I thought about reeds but it runs and idles fine and can play the boost by hitting the throttle on and off for a while.
I tried googling the symptoms of the tps but I couldn't find much other than most people saying their sleds would cut out or they had a weak idle/no reverse, all of which I don't seem to have happening.
