2000 2.5RS BRP
I scale my injector timing later as the revs rise, FYI.
Second that! I was hoping for a write up somewhere but at least we have this thread and the notes inside the software.Trying to figure out what does what in the software is what I've been trying to do since I bought it! My fuel trims are like -20% for LTFT and -3-5% for the STFT, but i havent spent enough time figuring out where to fix that (ie. using the target fuel ratio table, VE table, injector settings?).
If Project Lambda want to write a little book on how their software works theres a big chance I'll be the first to buy it haha.
Whats the specs of your motor Crawlerado? Mine is an ej251 with delta 1500 cams. Was very lean above 4500rpm, managed to get that to a stable 12:1 right up to 6200+rpm and its runing the 3bar maps sensor nively. Haven't touched timing yet as it rarely seems to make sense.. The timing figure doesn't equate to the base plus/minus any corrections and the IAM figure.
Is this an effective way of tuning? I know what we have to work with is extremely limited but I didn't have much luck with forcing OL and targeting 14.7 at the cruise rpm's with my emanage.Closed loop is supposed to be around 14.7+/- a little bit. My difference is that I just give it the narrowest possible window to use closed loop.
Even with boost, give it some more tip in fuel. These engines LOVE fuel.
I may have reached the end of the road on my second ECU. I've written probably 200 tunes or more, messing with little stuff. They're only good for 50 or so reflashes from what other sources tell me. This ECU appears bricked, or at least injured. The IAC programming bit me. Limiting number input ranges (I.E: +50max, -50min)I don't think was ever included in the software. This would go a long way with helping the end user know how far they can go with certain adjustments.
Yes. It still uses closed loop just at low throttle inputs and low kPa values. I tried to get it to just run in open loop all the time, and it "worked" but sucked as a street car. The plugs would fuel foul in a few hundred miles instead of clean themselves off at cruise. That's about all stoich is good for.Is this an effective way of tuning?

Hey guys, started having another issue (or always had it and mis-diagnosed it).
As I get into higher rpm (4000+) I start to lean out. My targets are all set to 11.2ish, however my wideband is showing closer to 13.5+.
My setup is a walbro 255, 550 cc injectors, td05-16G, 5-6 psi. I'm currently testing my adjustable FPR to ensure the boost referencing feature is working correctly, as well as replacing the filter element in my fuel filter. Fuel line wise I've got a parallel fuel setup with 6an lines.
Last season I had the same issue. However I was running 440cc wrx blues, a td04 at 6-7 psi, and a differently fuel setup (hoses and brass tee's instead of an lines). Same fuel pump, filter, FPR.
I've added a dropbox link to my "tune". Its rough but just need to get moving properly.
I'm starting to suspect a fuel pump, as the walbro was new to me last year. However with the huge amount of knockoffs, who knows. Anyone have any idea?
