How do I raise the rev limit?
 
I have a pr4 ecu and it's socketed. Now, how do I raise the rev limit on it? I've opened the stock pr4 map, but the rev limit isn't selectable in the options.

I smell a ricer. :P

Why exactly do you want to raise the rev limiter? Is your motor built? What exactly do you have done to it to warrant raising the rev limiter?

If you are using Turbo edit click file and then properties and that will brin gup the flag items. Just selector rev limits.

I don't believe you can do that in a stock rom. ???

No, actually not a ricer, I only drive a Honda for commuting purposes. Actually, It's a GSR in my friend's car, but he's using an LS ecu. Like I said, when I go to properties, I can't select rev limit, only fuel multipliers.

Ah, that makes sense. Sorry for misjudging you. ;)

I would suggest opening a boost rom and copy and paste the maps from the stock PR4 onto that and scale everything down for 240cc injectors.

Thanks. I can't believe how fast that response was. Alright, where do I go for the boosted rom?

And you maybe smellin' the rice from my clothes after hanging out with some of my friends. I'll admit they're ricers. Nothin' rice about MY turbo cars.

Here is a place to download/upload all the bins you could ever need. ;)

BTW, it's a sticky at the top of this forum. :P

I would suggest this one.

Got it, what do I do about "unable to scale to smaller injector"??

Eek, I dunno. I'm by no means an expert at this. Maybe just make sure the values are the same across the fuel curve? Will that work?

Re:How do I raise the rev limit?
 
oops, I thought it was a pr4, that's what he's got in there now, but we wanted to use a pm7 ecu, that's the one I socketed. Can I burn the same map on any ecu?? Or do I have to start with something from a pm7? I don't really understand that part.

go to www.------------- and find the 'basemapper deluxe' download. it's an excel sheet that will allow you fill out all of the properties and make your map for you, then just copy and paste the cells in to turbo edit. the exel program will allow you to put 240cc for injector size and scale the maps accordingly, then just paste it in ng48 and you'll be able to access all of the boost properties that weren't available with a stock rom. i don't mess with turbo edit too much, but i believe you'll also be able to then remove the speed limiter and activate the shift light and launch control as well ;)

Re:How do I raise the rev limit?
 
So you're saying the ng48 will work for anything?? That's what I'm a bit confused about. The same map I made thinking it was a pr4 will work on a pm7 ecu?

projekteg 01-22-2005 11:15 PM

Re:How do I raise the rev limit?
 
yeah, you can use different maps for different ecu's, the main difference between ecu's to run different engines are the fuel and timing maps, in this case you're programming the pm7 with pr4 maps, so it's running like a pr4 ;)

Jmirage 01-22-2005 11:43 PM

Re:How do I raise the rev limit?
 
Okay, I think I've got it. The different ecu's access the same areas of the eprom for information it needs. This way, any map will work on any ecu.

Re:How do I raise the rev limit?
 
Wow!! That was so very very easy. Got it done. A couple issues, but easy. Thanks for the quick help everyone.
