Quick EBL WOT WBO2 Screenshot
Ran the car with the LC1 hooked into the EBL today for a while, could only get in a few short WOT blasts because of traffic but I still managed to figure out some things. Here's a shot of the analysis. Commanded AFR is 12.8 so I'm running rich, but I corrected that already. The big things I noticed are the drop to 94/93 KPa MAP and the duty cycle getting up to 97%. I'm running the stock TBI with ultimate mods so either that is a restriction or the 14x2 open element. I'm also running stock 55# injectors at 21psi. So, according to my calculations, I have enough fuel at 97% DC to support around 315hp. I obviously need more pressure or a switch to one of the other sets of injectors I have around. It's hard to tell where they're going static, because the AFRs actually seem to match the VE table fairly accurately all the way up.
Just thought some of you may be interested in exactly what the EBL puts out and how easy it can be to tune with all this information. Looks like I'm making pretty good power too for a cheap setup.

That's a nice setup you've got, are you going to dyno it any time soon? I was thinking about upgrading to something along those lines.

Re: Quick EBL WOT WBO2 Screenshot
thanks, I doubt I'll dyno it any time soon, but I want to get to the track before it closes if I can. Just installed some made4you wire looms and new Summit ignition wires. Very nice products. about 28 bucks for the wires, and I believe they're made by Taylor, so that's an awesome deal to me.

Re: Quick EBL WOT WBO2 Screenshot
Only experience I have with the EBL is from my own setup, which is different from yours, but from the jpg posted, it looks like your already static at the beginning of that log section. The sPW is maxed at 5.7, and the afr is going richer, which on my setup, was when the injectors were static. I believe the DC% is still going up because the rev's are increasing, so the 'available' PW time is less, and the DC% goes higher.
My MAP goes down quite a bit also at upper range WOT. I made a run with no air filter and housing at the track, and picked up 2 mph (in the 1/8th), and MAP went from 92-94 to 97-98. So that shows it might want more air. Which is good.

I'm also not complaining about it wanting more air haha

Re: Quick EBL WOT WBO2 Screenshot
Well, after a few calculations, I think a 5.7msec pulse width is not static until about 5200RPM. But, if figuring that I want under 85%DC I still am probably on the verge of static injectors for most of that run. Time for a little tuning.

Not cheap, 115$ for the regulator, and probably another 70$ for the AN stuff, but its worth it. I had to replace the fuel pump also, but still worth it.
