Ok guys I'm running a Greddy profec E-01 on my sr20 240sx. now my biggest problem now is my intsructions for it are in Japanese.....its all installed but programming it is a *****. Anyone else running one of these could prolly help me out. Now its not totally programmed so i can't run in Auto mode (where u just input the amount of boost and it pulls to that psi) instead i need to run inj manual mode where i have to set the Gain, the set and the start boost. The set is a % and the gain says @ RPM (ex. 32) and the start boost is just psi. Now for a while I couldn't get the thing to pull past 12psi and that was beatin the **** out of 3rd gear....it was pullin 10 in 1st 11 in 2nd and 12 in 3rd with the Hi boost settings @ set : 70 Gain 60 start boost 3psi. Finally we started messing with the duty cycle and we set it in 500 rpm increments. starting at 4000PRM i went 4, 8, 10, 14, 16. and set the set at 70 and the gain at 15 and the thing pulled to 15.4 psi and i had to let off cause thats TOO MUCH. It smoothed out the spiking which it was doing alot b4 like jumping to 11.5 then fallin back down to 9 or 10, then spiking back up and falling repeatedly. Now what i'm going for is 14.0 psi for high boost and 12.0 for low boost. and i was wondering if anyone else was running this boost control and if they could let me know what the best settings for the duty cycle, set, gain, and start boost to get the Boost levels. Thankz guyz,:help
