BBL Logging and PID Selections

[kwhiteside]

I can get BEN Factor Ban 1, Serial wideband, LS1 Style, but all of the BEN Numerator PID require and ext analog connection??????

This one is the CALC.BEN1, but it still isn't a numerator PID??

Shall I use the BEN Factor Ban 1 in my map to replace the Ben-LC11 numerator and run it all over again?

Yes, for serial WBO2

[joecar]

Yes, replace BEN-LC11 with BEN1 in your map and save with new filename.

Pay attention if map is displaying cell counts, min values, max values, or average values (the last one is the one you want).

Post new screenshots and log/tune files.

Mark the intake manifold bolts with a paint stick to later see if they have rotated.

Good idea on the bolts, I'll do that.

Question for you. I'm going to get a good log after work tonight, but I noticed at the end of the tutorial we are expecting my LongFuelTrims to go down to -4 to 0 range. Being that mine from the track day were 10 to 25 all day long (maxed out) Is it really expected to see this kind of a reading?

Ok, pretty much thru the AUTOVE Tutorial. I'll post I'll my stuff up. A little unnerving how much it pinged when I got on it a couple times. I've pasted my averages over and multiplied to VE table, then I went ahead and flashed that up to the PCM. Thats where I stand now. I haven't taken it out again after that yet. I could do another run tonight, and I plan on driiving to work tomorrow. Looking forward to the next steps.

The two pics show the VE table before I pasted over and after pasting over with the average cells.

I looked at the log file and the few times I got on it (frames 4190, 6050, 6520) my afr is about a point richer than commanded. Maybe what we just did with the Autotun will help rectify that? Please explain to me as I'm kind of just following instructions without a good understanding of what we are doing. I see that the VE numbers have drastically been lowered after the paste, up to about 5000 rpm. (City driving, don't want to go to jail tonight!)

Oh, I noticed my long term fuel trims were right at zero the whole time. I totally don't understand how it changed so much. Please explain to me.

Where from here? More tweaking with this tutorial, or on to the next one?

Joe,

I skipped the B4001 Injector Flow Rate table and am backtracking. Can you help me figure out what injectors I have.

2001 Z06
They piece that clips onto them has a purple top and has "PED 42" written on them. I have reason to believe they may not be stock, but I really don't know.

I've hooked up a fuel pressure gauge and run at 68 pounds most of the time. I know stock is 58 pounds, so it appears my fuel pump has been upgraded.

If they are 42pounds injectors PED 42, how do I know what the Injector Rated Fuel Pressure should be. The spreadsheet has 43.5 in there.

I reread the tutorial last night and realized I didn't follow the last part right. I have now loaded the original tune, and alternate of SDAutoVe_000, then overlaid the VE table with the new values, Saved Original_Tun_0000 and flashed it up. Drove to work with BBL logging on and found my Long fuel trims -2 to -5 and my AFR staying right on commanded AFR. I was not able to get on it at all, it was a total cruise, but at least under those circumstances, AFR and commanded are in line. Also of note is that since I started messing with the AutoTune, I have not had the rpm dive bomb problem I posted about. Hope it stays that way as I progress thru the tune.

I will be able to make some tweaks during lunch and get on it a bit on the way home with BBL running. Hopefully you guys will come back from holiday or whatever happened yesterday and read this.

On the injectors, mine are gray and say bosch on the side.

I've researched like crazy about Injectors and have some understanding now.

Stock Z06 Injectors are rated at 28lb for 58psi 4bar. The spreadsheet defaults to 43.5psi 3bar because that is how most injectors are rated when sold.

So if I input a flow rate of 28 at a rated rate of 58, but then change my actual pressure to 68 which it is, I start seeing problems. This is assuming my injectors are still stock. ( I now know there should be a part number on the side of them, I'll get that when I get my glasses to read ) So I'm racing around and my commanded AFR is based on a 58psi table when actually I'm pushing out 68psi and more fuel. This explains why I'm running richer than commanded. Now if my injectors are upgraded bigger ones, that condition would be even worse to the rich side. The pcm is sending voltage to the injectors like they are small 28lb injectors at 58psi, but if they are big 40lb injectors being hit with 68psi, they will be releasing too much fuel.

How's that, do I pass Injector 101?

[mr.prick]

What injectors are you using?
You will need to change all the offset tables as well as {B4001}.
Do a search or start another thread for this info.

[joecar]

Yes, that would be why you're richer... recalculate for 68 psi (you measured this at the rail...?).

The stock Z06 injectors would be 28.8 lb/hr at 58 psi... or is it 28.0 lb/hr...?

I think the other injector tables may be ok at 68 psi, but I'm not so sure...
