That some serious rpms there. It's also way past safe, IMHO. A burnout is especially hard on a vehicle when you overrev.

Does the majority of all your chips have 7k set as default?

Thanks man,

BfB

 

This is done as per customers request. Our regular chips usually have the rev limit set at 6000rpms. Both 1BadTk and Wyldman run nitrous and on the spray the revs come on so quick they felt they were hitting the rev limiter so they requested the 7000 setting.

 

8:42 am - question posed.

8:46 am - question answered.

 

?? Is that a good thing, or a bad thing??

Oh, you might want to correct the settings for your UBB time display, the correct time is 11:42 and 11:46 for those posts.

 

Sal, he's in CA. The UBB compensates for timezone differences based on your settings.

By looking at the elapsed time between these posts and responses are made, I have come to the conclusion that all three of you are one in the same!

(oops, I mean all four of us)

 

I think trabuco meant it as a good thing. Saying your response time was awesome.

Well trabuco what if it's the wrong answer?

Sal we have a MAJOR problem. Guess what rpm my limiter is set at from you? I asked you twice if it was the correct number because I did not specify any limiter number but just want to know what it was. You remember what you told me? It's set at 7K and i don't have nitrous. Should I be concern now that I might BLOW my engine? Please give me your input on why my limiter is set at 7k by you....not me. I did not request that. I hope there are not tons of other people out there with the 7k limit. In fact in my opinion 7k is too high for any L motor. I don't care if it's for a milisecond or what. Our rods are already subject to heavey loads and a short blast to 7K just might gernade a motor.. Sal should I send my chip back so you can back down the limiter to 6K? I can also get the lastest and greatest program. thanks Jeff

 

***Trying to figure out why people do burnouts w/ Nitrous***

Other than the fact that this is a cheap way to "purge" their line, LoL.

Even so, I could never sell a chip to a stock blocked/headed Gen2 Lightning owner w/ a rev limiter past 6k. I believe that would go against my ethics.

Why keep in the run if you spin your tires? It's a lost cause, the run is toast for a best e.t., so why risk it...just abort!

Jeff, I set your limiter higher because you told me you thought you were hitting the limiter at 6k, and then I set it to 6500 and you said you still thought you were hitting it, so I raises it to 7k. Before everyone starts freaking out, there is something you need to understand. First, many times where we set the limiters in the software is not where they actually occur. So a limiter set at 6k may be shutting down a truck earlier than that. If a customer is obviously not revving to 6000 rpm but the limiter is kicking in, then we raise the limiter. This is based on customer feedback on a specific truck. Second, there are MANY limiters in the PCM. And not only are there limiters, but the limiters are broken down into "stages". There are 3 stages to each limiter. Each one starts limiting a tad more than the next until you reach stage 3 where that gives you an actual large power loss or engine shut down. The rpm that we state you are limited at is for the stage 3 shut down. If I set a stage 3 limiter ar 7000 rpm, the stage 2 is usually set at 6500 and the stage 1 is usually set at 6200. Most people don't feel the lower ones, but they do cut power. I also don't usually set rev limiters over 6k unless it's a race program, or the customer asks for that.

As for doing a burnout on the spray-- are you serious? People do that? Why would anyone do a burnout on the juice? The motor revs WAYY too quick like that and you can easily damage stuff. When I race on the spray, I purge before I get to the burnout box, switch the nitrous off, do my burnout and then switch the nitrous back on.

 

Sal,

If that was me flipping the nitrous switch at the line I would end up leaving the nitrous off for the race and leaving the truck in second gear which I have done several times and never hear the end of thanks to Jim(JDM), and Brian K!!!

I never ran nitrous, but I was using the nitrous switch analogy as something I would do in a racing situation!!!

I should have had some sort of checklist for the staging lanes!!!!

 

Sal I remember once asking you if you could raise my limiter or lowering my shifts points because I thought that I was tagging it. Just once...that is when it was already at 7K I asked you why I was dumping boost if I had a 7K limit. You did not give me an answer. I have since found out that I have been overclocking the pcm. I think I need to send my chip back so that it can be reprogramed... 7K is way too high for any blown chipped 5.4 to be running IMHO.
Here is some of your e-mail......Hey Jeff, actually the shift points on this program are about 100 rpm lower than your previous program. The rev limiter is at 7000, and it was also there on your last one too

I'm not trying to start anything here but there is a STRONG chance that I could possibily harm my engine with a 7K limiter. Don't you think I should have my chip reburned for a lower rev-limiter? Please let me know what to do. Jeff

 

Is this safe on Nitrous, or is this for your N/A and your N2O programs are different? On N2O this could be very harmful to an engine.

For N/A, why not just set all 3 stages to the same, say 6000?

Ah, ok, sorry Jeff. I had you confused with another customer. I have several "Jeff's" I currently deal with, and since there is no way to get someones real name on F-150, I get the screen names confused. I'll be more than happy to lower your rev limiter. Just shoot it back and I'll fix and update you.

 

Ok Sal I will. I'm glad that I did not blow my motor this Saturday at the track. I'm Jeff from Crete, IL 60417 I did have one funky pass Saturday but I'm sure it was not related to the rev-limiter. I'll get the chip to you for an update... 6k on the limiter too.. thanks
