are you saying what he said is false, well if so your wrong. if the blms are between 108 and 160 the a/f ratio is 14.7 so being at 128 doesnt affect anything, except if you have a exhuast leak before the 02s and your blms go to 110 then you will get bad gas mileage becuase of a false lean. but thats not the cars fault it yours for not fixing the leak. but with that leak it should be 14.7 as long as its no below 108

 

BLM's aren't as magicall as you think. Tune a car that runs 128 and compare it to one that sits at 110 and you'll see the difference.

 

Ok... I am going to hell but....... I changed the MAF tables back to stock ones and upped the injector constant a tad and the cars seems to behave much better, no more choking at 4000 rpm and it pulls like a friggin tractor. I just did a short drive. I will do about 25-50 miles tomorrow and see where the BLM's land. I amd going to try and set the injector constand back to where the tuner put it with stock MAF tables just to see, for the sake of aurgment so to speek. I have a sample of a MAF table with the factory "errors" corrected that i am try as well, only a few cells modified in it.

 

oh yeah car starts much easier too

 

I just looked at your order sheet and then your program and I did miss the injector constant (it's rare, but I miss things occasionally). I am tweaking your program and sending it to you with it set up for the accel's.
Thanks,
Bryan

 

Oh holy christ. Sorry. I don't know why I bother with this anymore. You and I have different ways of doing things and on multiple occasions you've disagreed with me and never explained why.
Fine, whatever.
And yes, I have tried it. Multiple times, on multiple cars. And not all LT1's. And in everycase what I said is my experience. I've never had a file that I did for another person not have blm's between 115 and 140 in damn near every cell. And I don't have to screw with the maf tables to get that result.
And I'll be damned if what I suggested wasn't tried by the author of the original post and what were his results?

Rooster, if you want to disagree with me that's fine as I'm not always right about everything...but at least explain to everyone why you're smarter than I am.

 

Know what Bryan, in an industry such as yours oversights like that are what cost people money.
But at least you had the ***** to admit you made a mistake.

 

We are humans aren't we? We do deal with 50 different cars a day and people who don't realize we can't remeber every little detail right?

The biggest thing is we work to correct it.

 

Don't get upset, just come to the tables with facts and experience. I'm telling you from having cars on WB's and driveing cars that are stuck on 140 etc and you will definately tell that the car isn't right.

In fact, try this on your personal car.. Add about 2 lbs to your injector constant to put it in a high 135-155BLM range.. Then go drive it and see how it drives.

Now, it is definately OK for the BLM's to vary from about 118-135 but if you average those numbers you get 128 (or thereabouts). Thats just normal operation and the car adapting to different alt, pressure temp etc.

 

What kind of facts do you require? What I gave was my experience and the experience of many others. Where are your facts and experience? I didn't know that my posts had to meet your criteria before I could give my opinion?
And that's all I did. And you decided to tell me that I was wrong without explaining why. If I am, so be it. But don't tell me to "come to the tables with facts and experience" when your only contribution was...
Ok, and I'm telling you that I have driven and tuned multiple cars while using a wideband and what I said is my experience.

Which one? The 04 Monte Carlo or the 87 GN? I don't have my LT1 car anymore...does that disqualify me from this discussion?

Ugh...ok. Not sure what that means, but I sure would like you to tell my why a car that shows blms of 115, or 138, or 147 doesn't run as well as a car that shows a blm of 128 in every cell?
Cause if there is something that I'm missing I would love to learn more.
Sorry Rooster, nothing personal, but you struck a nerve with me tonight...

 

It doesn't matter what car you try it on. Just try it. Raise the injector constant 2 lbs and watch the afr on your wideband and note how the car drives.


By your logic of the BLM's self adjusting there would be no need for custom tuing fuel, the comptuer does it itself. Now.. that isn't right is it?

A big part of being mature is learning how to deal with people who disagree with you.

Oh, and as far as experience on my end. I'm doing my 461th and 462nd cars today, so I think i'm more than qualified to make a good opinion on tuning.

 

Can you explain to me what a blm is/does then?

Agreed. I've been mature about this. But I've repeatedly asked you to clairfy why what I said was wrong. And all I've asked is that you explain why I'm wrong. But rather than explaining why I'm wrong you'd rather **** yourself with statements such as this...
And I don't argue that you're more than qualified to have an opinion, but at least explain why I was wrong so that we can all learn. As I've said, I don't know everything and if what I said was wrong that's fine. But I'd like to learn why.
You wouldn't be sharing some secret that you don't want to share or something would you? Cause if that's the case than just say so. It is your livelyhood afterall.

 

Bud, your still not getting it. Raise your Injector constant by 2lbs to put the BLM's off and drive the car. You'll see the difference I mean, that is if your car is in tune now and around 128's.

 

I have done what you've suggested. Did I do it on purpose so that I could see the difference? No. Have I been through this before and had cars that did this on initial programs? Yes. Did I go through and fix them so that the blms were more centered around 128 in each cell? Yes. Did the car drive any different? Not really.

This is my last post about this though. I just asked for you to explain why I was wrong.

 

I have to agree with Dan here Rooster. Please explain. By doing so, it helps us all. Where you come from is experience now put that experience into words that we can understand and apply to our own tuning.
