Incredibly lean after calc.vet.
I have a c5 with a modified ls7. Cam heads ls9 injectors. 90mm. I have been killing myself trying to tune it. I finally got to take it out for a decent drive and flashed in my B5001 and B0101. Now it is so lean it will not rev. at least it starts and idles better. Could I have my wideband set wrong somehow? Innovate lc2. Every time I log it it goes so lean I need to add 10 or 20% to B0101 to get to even run ok2002 Z06 922_0000.ctz. I followed the calc.vet instructions to the T.
LS9 injectors are not the best choice. They will give you some weird fueling issues from their angled spray pattern.
Are you running SD? Or Blended? or MAF?
I'm running MAF. I have a few issues. I can't disable the maf to tune. I pulled the yellow wire out to disable it. It will not run like that. So I plugged it back in. Logged a good 45 minute drive. coppied b0101 and multiplied b5001 then the car ran worse. It seems to create lean holes in the blocks that got changed. So bad that I get a flashing check engine light. wide band shows lean not rich. I may not have CL disabled, I can't seem to figure out how yet. It is definitely correcting the ve table while I log. I just don't know why. I have to be doing something wrong. I went into summary notes and corrected every table to log. I would really appreciate a nudge in the right direction.
Could you suggest a good replacement injector? If I'm right I just need to change the IFR and injectors and start logging.
Current tune and most recent log.
Can anyone give me a hand with this?
I use these in a bunch of cars and trucks.

Ill have to go get the other laptop to be able to open your tune. Your using a newer verison.Originally Posted by TJWells
But i wouldnt worry about tuning it till you get some better injectors. The LS9's in a LS3/LS7 intake will give you some weird fueling issues.
Unfortunately this forum is dead on the gasser side.
I got the correct LS9 injector data in the tune and set it up for OL-SD.
I find its much much easier to get the VE dialed in first.
Your VE table was a huge mess. Thats why it wouldnt run with the MAF disconnected.
Ill PM you my email if you need help getting the VE done.
Load this and get a idle datalog of about 10 minutes or so.
What PIDs are you logging?
