LSX454 swapped 95 BASS burb.
- Thread starter shady
- Start date
Little lower, little cooler, bigger sounds.
Someone needs to teach you how to take a screen shot
.(not what you think) lol
My anti virus removed the stock windows one, then went belly up, and I deleted it.... Now I don't believe it's protected in any way, but can't figure out what to do about it
I've had McAfee and Norton, and hated them. So I'm kind of lost as to what to do.

I got the last filler piece made and in on the drivers rear lower corner.
Now I just have to trim the panel to size and start tacking it in
Also, I decided I am going to have to replace this well lip. Probably up to the slight flare line.
You can see the definite bad spot, but if you look close along the whole edge you can see it's swelled up a bunch of places.
They don't seem to make a specific repair panel for that spot on a burb. So I'm hoping real hard that the pickup truck one I ordered fits.

It only kicks the rev limiter based on RPM, and it's either on or off, not somewhere in between. If you go to the rev limiter line, it will show min and max at the top to show if it ever triggered it. Your data log is confusing , and with a screen shot I can't see the actual data to see what happened.
It does look like it was slipping and you let off before it completed the shift.
You will notice you can see with the yellow line when the shift was commanded, and then you can see from actual RPM and Speed how long until the shift actually happened. Even on a good shift it takes a little time.
Blue line is the limiter.
Kicked at 6400. Not 6800 as it's set for, and only after it slipped.
Only time I've ever actually had it trip the limiter since it was set for spark high only, was the 1-2 shift with that bad transmission.
Not once did it ever come near 6800.
I was letting up before it shifted not because of slip, but because of the speed I was going already and the road I was on. But I was still pulling it hard.
The second it tripped the limit I let off the pedal all the way.

You might find some help on the Holley forums, or just googling, on the actual algorithm for over-rev protection. Maybe you expect it to do nothing until the rev number is 6800.00, but it may start lower based on "RPM dot" (1st derivative of RPM). Especially if you're in neutral (or break your diveline or something bad), you could overshoot in the time it takes the adjustments to take effect. Some software has like a desired max and a hard limit.
What does it do? Just cut all spark?

Its pretty normal to be 200 - 400 RPM early when it first hits, when you set the rev limit it tries to not let it reach that limit so depending on how fast the crank is accelerating, it may come on early. That is typical of MSD box limiters too.
I don't usually see above 400 early, but you make me wonder with yours I have to admit, either way, raising it a little higher to get your actual RPM where you want it is common.
However, when it hits the rev limiter, its either on or off, 1 or 0, so it doesn't make any sense you have two diagonal lines, that is not normal. What happens in the data log when you hit it, each time you hit it, it has two vertical lines, one for when you hit it, and one for when it turns off. Because its normally 0, then you hit it, it goes to 1 for on, then back to zero. Its a single digital data point, 1 or 0, so a diagonal line doesn't make sense.
It has several options, soft limits, high only, spark only, fuel only, spark and fuel, etc.

So here is how I have mine setup. It does not hit it early at all on the main limit.
Main Limit I have as fuel and spark, and it does not hit it even at 7440 in my logs.
Limit #1 is during the burnout for consistent burnout wheel speed.
Limit #2 is on the two step on the trans brake for consistent launch.
I do not have on the "soft limit".

I suspect it's just an artifact of how it draws the graph - it's always connecting data points with straight lines. You'd need infinite points to get truly vertical lines there.
If I stay on the gas when it hits that, it does not go any higher in rpm.
I tried that. Just found asmt logging that time.
I was pissy so I stayed in it a bit looking at the gauges to see if a sensor was off or something.. and it stayed between 6300-6400.

I have a zipped file that I planned to put on the holley forum. Had my tune at the time, and that log overlayed.
But the more I dealt with the holley site the less I wanted to deal with the holley site, finally flipped my computer the bid and have never went back to their forum.
It kept jacking me around on signing in, stared back over from scratch and it then said I couldn't because there was an account with my email already, so I went through the BS to reset it all, taking pics along the way. Got all done and it wouldn't let me in.
Again.
But, the place reminded me of PIRATE when I was in there, so I just kind of said fug em.

Yeah I went and looked at one of mine, it does the same thing, but my scaling uses the entire height of the graph screen so it appears vertical, when you make the line 1/3 of the height, then the slight angle is obvious.
It is still only zero or 1, nothing in between in the data, goes from 0 directly to 1, however, one data point over is .020 second later in that resolution I recorded, so that makes the line at a very slight angle that appears vertical with the full height.
I have hit it if I have the throttle too high yes, usually I am just below it as I don't let it sit on the chip. (we still say hit the chip even though we don't uses the little chips/capsules any more.
)If you want to send me your log and your tune file I can overlay and look at it for you. It might just be a matter of switching what rev limit type you use.

I'm using the same one you are. Just set at 6800 instead of 6500. So if you can get almost to 6500, then I should be able to get to 6800 lol.Yeah I went and looked at one of mine, it does the same thing, but my scaling uses the entire height of the graph screen so it appears vertical, when you make the line 1/3 of the height, then the slight angle is obvious.

I seriously think it wasn't happy with what the trans was doing, (hey, I shifted, but the shaft speed is still climbing!), and trip the limit as a safety.
I'm pretty positive it's not going to do it with this trans.
And, around like July or something last year, I believe I sent you that log and my tune lol.
Because of the limiter. May have been later than that. When I get a chance I could again. But I don't believe it's in my limit settings at all.
I know I was able to get near the limit with the original trans. I had it set to 7100 with that engine, and I know for a fact it was still smooth at 6900 once, because I had the whole "69!!" Moment lol.
I don't data log the burnout, I did for a few runs years ago but always had to zoom in to the run so I just eliminated it, I may be hitting that one it at 6300 I don't know.
I can tell you this, I have had to adjust the shift point lower so I don't hit it. And I know of a lot of people, including myself who have had to move the rev limit higher to have a clean run off the rev limiter. If its consistently hitting it 400 RPM low, you can raise it up.
For example, my shift points are 600 - 700 RPM lower than my rev limiter, because if they aren't, I hit it when I spray it, and it shifts firm too, no slipping. SO a shift point of around 6800 for 2nd gear and my actual RPM hits ~7440. Without the spray I can get away with a little higher as the RPM is climbing slower, but its still a big gap from shift point to rev limit, because in that short amount of time the engine climbs 600 RPM or more.
I have a dominator ECU, not a Terminator X Max, so they may not be exactly the same, but I have used Terminator X with a lot of success too, if you dont need internal data logging or high current injectors don't spend the money.
Didn’t my truck have this issue?
Yes I wouldn't really call it an issue, its normal, just a trans tuning correction.
The actual shift point is what matters more than when it's commanded to shift. RPM will climb faster in low range, on the bottle, under boost, etc.
If he is hitting the rev limit, I would raise it.
Now, if its not consistent, and it hits the rev limit under WOT at 6400 one time and 7000 the next, that could be an issue.
