Hey guys,

Just got EBL and I must say it's awesome plugged the LC! in, got it up and running, open loop locked blm's raised closed loop enable temp ect.. Anyway it's running way rich 11.9-12.0 off the commanded open loop afr which I have set at 14.7 idle and all through the rpm range. Whats weird is that it stays right at 12:1 throughout the rpm range when I rev it. I used the ve table and spark table from a vortec bin. I'm running 16psi on a 454 tbody 80.5# injectors BPC set at 101. I have a chip burned before that was close but not perfect and it was running closed loop but way rich on wot. I noticed the fuel map on the chip I bought the VE table seems to be manipulated to compensate for the increased fuel flow 20 at 800rpm vs 36 on the EBl vortec table. Anyway I would like to VE learn open loop. Should I reduce the BPC until my WB afr matches my commanded afr? Or should I copy the ve table from my old chip and use the correct BPC 101. Or last but not least should I break down and get a VFPR. Thanks in advance for any info or help - I'm hoping to get it roughed in good by the weekend so I can take it on a trip!

 

Update on earlier questions and only two. I changed and modified a much better ve table for my engine -, BTW (383 10:1 all forged eagle rotating assembly and pistons, rpm intake, 454 tbi, comp xfi 260 cam, pretty much top of the line everything). What am I doing wrong, EBL - I'm running a wideband is staying at 12:1 all through the part throttle range even though I set the open loop commanded range anywhere from 14.7 at idle to 12.3 at 4000k rpm and above. But it is staying at 12:1 no matter what. Also EBL is stating a different AFR from my LC1 gauge about .8 less. Gauge on LC1 is pretty close with NB sensor so I know it's calibrated correctly and yes they are all grounded same spot. So anyway main thing what am I doing wrong so the calibration is commanding 12:1 no matter what?

 

For the WB reading on the EBL, make sure that the WUD LC-1 WB set up is the same as the LC-1 is set up to. Can then adjust the set up values (create a user device) to compensate for any offset voltages. This is common and only a few 10's of milli-volts can change the displayed value.

Also, the LC-1 units can revert to the default set up when the engine is cranked. So it is usually best to use the default LC-1 output volts/AFR for the WUD user device.

The commanded AFR and WB reported AFR not matching: this is from the VE table not being correct. A VE Learn via a WB compares the commanded to the reported and adjusts accordingly.

Thanks for the info, I wish I had of read it earlier I would have created a user defined WB instead I went to reprogram the offset on analog 1 vs analog 2 on the LC1 and it won't work keeps going default lambda even tried an old laptop to do it same thing though. When I programmed the output yesterday for AFR it worked fine, now it won't. So I'll spend the day getting it to work again. I did get the ve tables much better after 10 wb learns. So if I can't get the WB working I'll use the NB for a bit until I get a replacement WB.

Thanks,
JW

 

Just want to update-- EBL is incredible--! In a day I went from a burned chip and was only getting about 8-12mpg, now I'm at 16-19- simply amazing thanks to EBL and all the incredible info. Wideband learns and about 5 hours of driving, now I can't stop tuning it's addicting!
