i been driving my b16 swapped hatch for awhile and finally got to a place whare i felt high rpm's were doable without getting pulled over and it cutout at 72k?? its a obd0 pr3 ecu in a 89si... the only code i have is a knock sensor because i dont have it hooked up yet. could this cause the low redline? vtec is working at 55k like its soposed to

 

7200 seems like a pretty high rpm to me.

 

not for a b16 redline should be past 8k

 

stock rev limit should be 8200. might be 800 with a pr3. correct me if I'm wrong anyone.

You need to hook up the knock sensor

 

yea the knock sensor should fix it

 

alright, i know its soposed to be 8200, and it runs just fine other than that

 

i run mine too 8000 just to be safe ..

 

i think b16 should be running at 10,000

 

You may have the automatic B16 ECU. If I remember correctly, you can tell by opening the case of the ECU up and looking on some chip on the inside that says AT or MT on top of it. I think that may be your issue unless you have a CEL or something.

Negative... an easier way is just to look at the number on the side of the ECU. That will tell you if it is Automatic or Manual. If you don't know what you are looking for post all the numbers up and we can tell you.

Mine REV's to 11,000 RPM...

 

Of course you could check the numbers on the outside (easier) but can you not open the case of the ECU and look inside or am I just blowing smoke? I read that quite some time ago somewhere...

 

37820-pr3-003, i looked upthe numbers on hondata.com and its a manual ecu..

 

did you hook up the knock sensor yet?

 

no thats prably my problem but i tried it without the ks cell on and it still redlines at 7200.. the cell is intermitent

 

Hook up the knock and your problem will go away, Also check your timing that can cause your early rev limit. Was the car fully warm?

 

yeah... a b16 goes to 8200 bone stock.. at least mine did, and everyone else's.. haha

and you shouldnt be getting on it without your knock sensor hooked up.. When i got my eagle talon, the a$$hat before me had disconnected the knock sensor, so he could turn up him boost hella high.. EVERY piston was broken all around the rings, and the top of the pistons were all kinds of ****ed up.. hahaha..

the Knock sensor retards your timing when it senses knock.. its basically just a microphone that hears knock at the right frequency, anad helps to remedy that..

hook up the knock sensor, and you shouldnt have any issues..

 

I rev my stock B16 to 18,000RPM all day....
