problem
 

i've had my car on the raod for a week now.. and last night i went to cayuga.. but it seems my rev limiter is at 7400rpm.. its a first gen b16 with a pr3 ecu

also vtec kicks in at 4400 rpm
sounds like it could be an ecu problem?
i've heard that the guys i bought my engine off use canadian ecu's from hperduck.. and they aren't proper.. but i'm not sure..
does this sound as if its an ecu problem ?

that sounds ok tome? what don't you like about those settings?

well the b16 rev limiter shouldn't kick in till 8200rpm and vtec issuppose to be.. ( i think ) 5200 rpm

get a proper ecu..

well apperently it is.. B16a's need either PR3 or PR0 ecu's and this is a PR3 .. thats why i want to make sure these symptoms are from an ecu and not from sumthing else.. i dun want to waste money on an ecu that wont change a thing

I have a b16 with a pr3 Vtec kicks in around 5200-5400 and readline is around 8300. I would say you have a ckipped ecu.

thats what i assumed with the Vtec kicking in so early.. but what about the rev limiter?

rev limiter is also programmed thru the chip.

so what i open up the ecu and see if there is one in there?
if so can i jus take it out?
and why would n e one buy a chip the lowers the rev limiter?

If the vtec is kicking in at 4400, your max power is probably coming out at lower rpm too, so why would you need 8200 rpm if max power is earlier, and then drops off.

so they dont blow the motor :wink:


if you can find a buddy or someone on here that can burn ecu's you'll be ok... b16's need the rpms to make power so you'll probably gain power using a proper ecu :thumbup: since max power is at 7800 rpms in stock trim :drivesafe

is the chip removable and all is well.. or should i just buy a new one?

Chip is removable, however you'll have to intall another one in it's place for the ecu to work. I might be able to help you out, drop me a PM.

well i did open my ecu up today and there is no chip...
its weird..


but i borrowed a nice authenitc SPOON ecu :yummy:
noticed a HUGE difference

can you post pictures of the inside of your ECU...? ( so that those that are here can see whats going on in there,... :p

also is teh ECU throwing any codes?

well when i changed them.. it threw secondary O2 sensor.. just as a punched the gas.. then i changed them again .. same light.. sometimes it never goes off.. but sometimes it does.. is it anything to worry about?

and i'll take a picture later
