Some scalars will need changed and some will not. If you have a bin that runs don't mess with the PROM ID or the checksum - the checksum for one thing is automatically updated by tunerpro when you save the bin.

You should read through RBob's tuning guide so you understand what needs to be changed and why. And before you change any values look them up in the reference so you fully understand what it is you are changing and what effects it will have. This is a learning process and it's not going to happen immediately.

Did you correct the oxygen sensor situation?

Working on the 02 thing now. Scott wrote a good bin. It ran ok just needed tweeked. I'm trying to get to work with the ebl

 

Copy everything you can. Then do a datalog and play it back with the history table open and set to history averages in the top box. Then work your ve tables. say you have a cell that is 118 divide this by 124 and use it to multipy the ve value of the same cell. I work everything to within 124 and 128.

 

Wow, this thread isn't going too well.

First off, the EBL P4 isn't maskid $8D. So can't copy directly from the former BIN to the EBL BIN. To explain better, the XDF file is based on the calibration layout, which do not match between $8D and the EBL Flash products.

That is like using a road map of Toledo to navigate Boston.

If you want to use the SA tables from the previous $8D BIN you will need to manually copy/enter the points (by RPM & MAP) of the $8D SA table into the EBL BIN. Then interpolate the missing rows and columns and extend the SA values into the higher RPM. The EBL SA table(s) are of higher resolution and extend to a higher RPM then $8D.

And, they are not in the same location of the BIN as each other.

As for the VE (Mr ******), just do auto VE Learns. It makes quick work of the VE table(s). More so when using a WB setup.

Charles, for best WB VE Learn coverage, also disable the highway lean cruise mode. Set this parameter to 150° C:

HiWy - Min Coolant

Can re-enable it once most tuning has been completed.

Usually need to disable closed loop, but without a NB sensor it won't go into closed loop anyway. If you want to post a .dat data log, zip it first.

RBob.

 

Ok manually copy and paste Scott's sa tables?

Disable highway lean

I hooked the narrow band back up and installed the wb so i will have to manually disable closed loop in the tune

 

I think I'm finally getting somewhere. Used ****** spark tables and did what rbob said. Idles better right off the bat and not as rich. Will post datalog after a few ve learns in idle

One question. When do i enable closed loop again?

 

You enable closed loop after you do the wideband VE learns. RBob also suggests doing a few narrow band VE learns again after enabling closed loop.

You really don't want to run open loop all the time. There are varying conditions where the speed density system gets pretty far out of whack if you don't have the narrow band feedback (such as hot soak restarts). I've seen my AFR's go crazy lean sitting in a hot drive-through with closed loop disabled. Makes the idle and the off-idle progression pretty terrible. The reality is that having the magic 128 BLM at all times isn't really possible or neccessary. The system has the ability to adjust for a reason - because it just wouldn't work worth a darn if it didn't.

So ve learns while driving need to be done in open loop as well?

 

Made alot of progress today thank you guys. Car idles better than ever. Only issue is when i put in close loop I notice that every so often the idle drops to around 700 then comes back up. Any Ideas? Attached are my current bin and the data log

 

Only wideband VE learns are done in open loop. Narrow band VE learns are done in closed loop.

GD

 

Oki figured some stuff out on my own. The ve learns should take care of allot. I realized that to learn in closed loop mode i have to change the preferences in the ve learn window. Now i remember someone telling me i can use the original memcal for knock sensor and that there were other options can someone on me in the right direction for that

 

Ok this thing idles great now open and closed loop. Stalls in d and r when pressing brake hard. Any ideas what to mess with?

 

I think i figured this out. I was getting a malf code of high map. I raised the map high limit on the ebl and it doesn't stall it now. I have a few questions now regarding some observations


The closed loop nb reading seems lean. On the diagnostics graph in the wud the nb is up in the 20s and the wb reads around 15 or 16 why the big difference? Which one is correct?
Also what is the correct afr in idle? I noticed i am at 15 to 17 isn't this too lean?

 

The AFR scale is for the WB. The mV scale is for the NB.

RBob.

 

After playing with everything the wb read 14 ish at idle... The blm is pegged at 108. I did research and I'm sure i need to play with the 02 mv tables but not sure which direction to go

 

The BLM is the long term fuel trim. Need to lower the VE table in the area that is causing the BLM to be 108.

RBob.

 

If i do that the wb goes lean like 16 or 17

 

Does the engine still run OK? If so then don't worry about what the WB is reporting. Can also run open loop idle.

RBob.

 

Engine runs great either way....i was worried about a lean condition i don't want detination and i have no knock sensor with the ebl

 

Car idles and runs good now. I started tuning the high speed ve tables. I've learned that my cam overlap makes the wb useless for tuning idle and low speed tables. I used blm learns to tune those areas. I have forced open loop and disabled pe to run the high speed tables manually via wb data. My question is what is the target afr? I think i understand that the when pe engages the ecu uses the ve tables to adjust the afr the 12.8 when in pe. Does this mean i should tune the ve to stoich then let pe take it to 12.8? Am i doing this correct by having pe disabled and forced open loop?

 

Only tune the full VE map to stoich if you're a stickler for the numbers being accurate, which is what I normally do. It's a waste of time though. Just smooth out the VE tables based on the areas that you know are already stoich, then work your way up the map increasing injector duty cycle in a smooth and linear fashion. It doesn't have to be perfect, again, unless you're a stickler. Anyways, just target your PE air/fuel, and using the wideband at those upper RPM's, change the PE accordingly until the wideband reads what you want it to read,because that is all that really matters in the end.

How do you like the ebl compared to the tune you had before ?
better power/throttle response?

 

Edit: That question wasn't for me, deleting post...
