Car Leans Out - Turboedit Cells Are Maxed - What Can I Do?
Hey guys. I recently upped the boost to 15lbs today and went out for a rip to get some baseline numbers
I richenned up all my boost portion and got it running at about 10.8:1 up to about 10 psi. I then gave it and went for 15psi in 3rd gear and as soon as the boost gauge shot up past 12psi or so the number leaned out crazy fast.
Went into turboedit and added 20% fuel, the number in the cell is 20.62
I ran that car on this and did the pull in fourth gear this time and once again @ about 4k rpms and 13+ pounds the numbers started leanning out fast
The car is an 88 Crx si, dsm 450's, turboedit running a gm 3 bar map sensor and walbro high flow pump. Adjustable FPR set at 41 or so psi
I need some help on this. Let me know what I can do
Thanks guys

Re: Car Leans Out - Turboedit Cells Are Maxed - What Can I Do?
how do you run such a high duty cycle?
I was planning on maybe bumping up the fuel pressure to about 46psi or something like that seeing if that would maybe help. I would have to redo my entire tune though
Any formulas for this?

I put the stock regulator in, it definetely raised my fuel pressure and I had to redo my entire tune, got it dandy tonight and went boosting, its still set to hold @ 10psi and the ------- numbers just keep leaning out, I dont know what to do here

He was joking about the duty cycle LOL. In theory, 100% DC would be open all the time, though in practice 85-90% is all you would be able to run.
What you need to confirm right now is that your static fuel pressure is correct at WOT. If not, you have a regulator or pump issue. If it is correct, you need to do one of the following:
Bump DC to 85%
Increase static fuel pressure
Install larger injectors
Also I may have missed it, but are you running 1:1 fuel pressure ratio or rising rate?
