Went to do some VE tuning on my truck. Noticed in VCM Scanner was reading 20.3 no matter what I did driving. When I turned it off it went to around 8. Ordered a new Bosch WB02, did the heater...

Well I have a set of L67 injectors currently in my LS1. So that opens quite range of options for ya!

DAMN! THANKS!!! That looks very helpful!

Hey guys looking to put some 36# L67 Injectors in my LS1. Does anyone have a corresponding pulse rate, offset chart, or anything like that from a stock tune? I have visited the repository but only...

....and the log

Well after hours and hours this weekend I got it to where it seems pretty close. I ended up shortening my min PW, and doing some scaling to the offsets. Will someone just (PLEASE) look at this log...

EC, is rich decel something I will have to live with? I did as you suggested and almost all the cells are checking out perfectly, but the decel cells (15-30 KPA) keep coming up rich. Thanks for all...

What % increase would you recommend for a starting point?

Thanks again EC, just got back from vaca will try and load this in the next couple of days.

Anyone?

A shot in the dark, but have you checked the fuel pressure at the rail?

Well, after 2 hours of logging I now have cells that are off in the positive plane. Most of the cells are checking out, but now I am getting around +10 in cells 55MAP and up in the 1200RPM range and...

THANK YOU! Cfg changed, will do some logging today!

I have run my LC1 behind my new Racetronix 42lb Lucas injectors and I keep a rich condition in the low/decel cells. I used EC Tunes scaling and offset values found here:
...

Yeah, I dealt with the same problem. The best mod I did was trade it in. I got tired of an all around average of 14MPG!

Anyone adjusted thier cruising cells in the VE table to run lean? I have a wideband and was wondering if I just changed the 6-8 cells that my car hits on the highway would that essentially be a lean...

OK, we logged the timing and put the values closer to stock. No KR is being pulled and no noticable difference. We logged the PE and it isn't kicking in until around 3600 RPM, is this common or is...

WOW, sorry guys!!! Been on Vacation, still am. Will check into these things and post back up. THANKS!!

Yeah thanks, I understand that. I am just confused what tuning differences there are on some 5.3 trucks that make some have gobs of torque and some lack all low end power. Granted it is cammed, but...

Hey, this is the tune from my buddies 02 GMC 5.3. We are having a hard time with gains down low. The truck has a small cam, LTs + ORY, Efans, CAI, and a high flowing muffler. The truck wont even...

Hey man, thats ironic! I just sent you a TBSS tune this morning! I was on here browsing around and here you are too. Anyhow, I was getting alot of KR all over the place. With the tune I sent, I...

I suppose that would be another option. I found the wiring and will post it up just incase anyone else has this question down the road:

Purple/wht= high
Tan/wht =low
Pink = 12V
Black = ground

Ok, thanks for the heads up. I will check into this when I get the time. Much appreciated, J.

I have a portable LC1 wideband for my 98 Camaro. I would like to use it on my buddies 2002 GMC.

I need to know what each pin (A,B,C,D) are on his sensors to make it work. His O2s plugins are...
