ok quick question, i tried to search but everything i searched was way to broad and brought up pages and pages of results... :s where does the stock pr3 obd0 b16a ecu open vtec at? i read 5800 is that correct?

 

that sounds right. It should be around mid high 5000. 100rpm off either way isnt going to make a difference.

X2----5700-5900-----

 

and the louder the jerkier the better.

 

I like the PW0 it kicks in at around 5200,

 

huh, maybe im running a pw0. i can't figure out why but my car opens vtec at 48-- to 49-- rpms. what the heck could be the reasoning for this? i'm not throwing any codes, either stored or on the dash. it also runs rich as can be. it's not so noticable when i have the car on the floor but when i let off the gas to shift it will often times have a large puff of excess fuel being burned off or even backfire a little blue flame. as said only when im on the floor and shifting of course in vtec. any ideas?

 

i ust to run a pr3 ecu on my b16 and vtec would engage around 5200 give or take a few 100 rpms. the y8 ingages around 5800.

 

might be chipped.plus if you want to know what ecu your using then look on your computer where the barcode is and it will tell you.pr3,pwo etc...

 

the pr3s vtec engage at 5200 and redline at 8200. UNLESS it is chipped. but as double trouble said it would be alot easyier if you would just look on the ecu. it says it flat out.

 

my b16's got pr3 vtec hits at 4500 rpms, o wait I got mugen ecu chip hehe 95k redline

 

My PR3 (obd1) engages at 6250...

 

i know where to look for the ecu code. thats not the issue at hand, i just though 4800 is a little low for any b16a obd0 ecu.

 

4800 is for single cams, cuz they dont rev to 8200...


but the obd0 b16a ecus factory VTEC is 5200 RPMs

 

4800 for single cams? the y8 engages at 5800 and redlines at like 7200.

 

EDIT.


my ecu was chipped due to boost so my V-taaackk was set to 4500 and now that i think aboot it my roommates gay *** 98 coupe was set to around 5800 which meant he was only in vtec for like 1200 rpms(auto shitty)
