I just give him the new data logs yesterday,don't think he will need to adjust anything but we will.see.I think it's a tad rich .76 .77 but I can turn down the bap a little more too if I want.Then when I pulley down I can add fuel if needed without needing a reflash.
Mine is like .79ish in midrange, then up top it gets real safe at .76-77

Yea mine too and to me just my opinion I think that is a little to rich for e85..79 to .81 is where allot of guys that are running e85 seem to like,at least from what I read.When I was having problems my a/f were going as lean as .90 up top and not one sign of detonation,this shit is amazing how it resist knock.

From what I understand it won't knock on e85 pretty much until it goes kaboom...lol.

Wow that's kind of scary. I'm looking forward to tuning with E85 soon - the safety margin it provides seems amazing from all the stories I've heard. I got worried when I started creeping above .81-.82 towards top rpm (pump gas) which is how I ended up with a BAP and now moving to a fuel system.

The one Achilles heel of e85 is it someone prone to pre ignition,crazy how it's so knock resisting buy can be subject to pre ignition,I read in some cases depending on setup that u have to ramp the timing in a little slower as where good race fuels u dont.

Well put my car on the dyno today to try out the new fuel system,d1 with 4.88 pulley running through the auto and 735 rwhp and 575 torque,on a dyno jet.Will have one of my buddies post up the dyno sheet when he emails it to me.

Hey guys just an update on my g350 pump install.Everything is done now and I took the hand full of suggestions guys were giving me about running a boost reference.It made a huge difference,so much I might take the bap back off,my pcm is commanding less fuel now all the way to 7500 rpms.But here is the better part I was getting knock down low rpms at wot.Well turns out having 63 rail pressure at that low of an rpm and basically no boost was causing knock,it's gone now no knock and have more fuel if I want to pulley down in the future.

:cool:

Stock manifold no headers,cat deletes,also this is on the 4.88 pulley,I can drop down 2 pulley sizes easy.It will run 9's just like it is.

My car on 13-14 psi on E85 seems to be perfect with the Sai Li base fuel system. No leaner than 0.78 lambda in my logs in 3rd gear up to 7700 RPM. Using ID1050X injectors.

Where do u connect the the dual 10 gauge red wire to? It goes from the battery fuse box to where?
To where ever your going to mount your relays at.

But I’m asking does it connect Directly to the relays?
Yes,the heavy gauge wires from the battery are you positive feed wires for relays,one wire to each relay.
