I’ve been quite busy lately dealing with trying to move back to the states, so this has been on hold a hot minute. I’ll try and find some time this weekend perhaps, or the next. No promises there, my plate is overflowing right now dealing with buying and selling homes, and of course actually getting ready to leave. I didn’t forget though, just been very tied up lately.

I'm glad I'm not trying to do any electronic idle control. Prime pulse on mine is just zeroed out, stock. I guess that's an option, or it uses a per 90 degree table that starts high then slopes down quickly.

Hi, do I need to scale if I'm using 2Bar OS?

Hey there, not sure that the VE table needs to be scaled for a gen 3 ECU. You technically already scaled the airmass when you scaled the displacement. The airmass is essentially displacement * VE (VE on Gen 3 is just a % of displacement, unlike gen4 where it bakes both values together). By multiplying VE by your scale again, you're over-scaling the VE table.

True, however in practice it doesn’t always work out that way. Another symptom of needing to scale in the first place is numbers on the VE far beyond 100%. I’ve seen numbers as high as 130% on N/A cars, which is “impossible” but is what it is because that’s what it’s asking for with those injectors. In practice slight adjustments to VE after scaling are often needed, but I haven’t seen anything off the charts after scaling it. I suppose you could technically skip that part, because you’re right, but for whatever reason it’s going to show pretty rich after the fact if you don’t scale that table. The idle areas do require attention, because of the unseen formulas behind those, but the WOT areas and so forth don’t need much work in my experience. Honestly you have me wanting to compare my files now to see if the numbers came back in line lol. The physics are complicated when talking airmass too, which is another major factor, so % of displacement isn’t necessarily as simple as that sounds.

So in simple terms, for what I’m saying, if my VE numbers were above 100%, say something like 120 or whatever, would I then leave that number alone, or should I drop that down by the scale percent? Which in this case should be at least 25% leaving my new number saying “90” and not 120. Just because it allows numbers above 100 doesn’t mean they are correct, unless we’re talking about boost. Does that make sense now? The whole point is to bring my airflow limits back into the margins. That also implies my VE is also “off” by at least that much.

Yeah i get what you're saying with regards to VE numbers that are comically high (120+) are just to overcome airflow issues and should be brought back down. In theory you shouldn't have to scale any sane VE value on a gen 3 ECU though. Of course nothing is perfect in practice. Just figured I'd call out this one thing i saw. The video is well done, though. Great reference

The concept for the rest of the numbers is the same. Once adjusted to a set of injectors, none of the numbers are going to be right if you scale only the injectors. The presumption is that scaling is needed after a calibration in this video. Therefore, everything in the tune is off by the amount determined by the amount out of limits. Since this means the VE is changed to map those injectors, the entire table must be changed to reflect the percent change applied to the injectors. Otherwise you’ll be pig rich and need to adjust anyway.

Not sure if you'll know, but does the fuel qc need doubled as well?

@ChopperDoc181

You are talking about fuel qualifications right? Under transient? I’m not sure why this would be doubled. Normally the only time I mess with transients is when fixing tip in or tip out AFR spikes. Since the entire fueling calculation will change, most of the transient fueling will be left untouched since the input formula will be reduced by the scale percent.

Forgive me if this is in the video and I missed it. So I am installing 80lb injectors and plan to scale by 50%. Would I scale the injectors too, by putting 40lbs in the KPA vs flow rate (injector flow) or would this stay at 80?

@ChopperDoc181

2 жыл бұрын

Yes you would reduce the flow rate by your scale. Make sure you use your injector data from the injector manufacturer first. It is actually in the video, but that’s okay. You don’t have to change really any of the other data because it’s mostly time… therefore it stays the same.

Hey.what happen..your videos are dying off.. you do the Best job explaining things .. I had a question tho.. if I wanted to start over on my tune.. on hp tuners.. do I just pull the stock tune file up and just reload it.. do I write it as a change or entire ..

I’ve been in the process of moving, fixing up the new house, and training for an Army school coming later this week. I don’t have internet set up at the new house yet, and hardly enough time to finish even half of a seemingly never ending list of tasks. So naturally the KZread thing has to take a backseat for now until the dust settles.

To your question, pull your stock file and save it as a stock file. Any modifications made to it should be saved separately using the “save as” feature, and most folks make a new folder so the stock file doesn’t accidentally get over written.

why does this need to be done? Does this need to be done for just a cam swap?

@ChopperDoc181

It’s done normally when you put in larger injectors, and you want to stop riding the bottom row on your spark tables.

Why do I need to scale by 0.8?

@ChopperDoc181

Жыл бұрын

It’s entirely dependent on your need. Many scales are 50%, especially for boost applications. Some go even farther. I explain in part 1 how to determine a scale amount before starting. I used .8 to show a more difficult scale, for the purpose of the tutorial. As long as you use the exact same number throughout the tune you’re golden.
