i just helped a friend put in a b16 into his 91 si and it started, no probelms, no check eng. light, wired it up for vtec, the only thing is that i didnt hook up the 2nd o2 sensor but we didnt get a code for it, so we took it for a test drive vtec kicks in but it only redlines to 7000rpms does the stock ecu only go to 7000? any help would be great.

 

are you using the b16 ecu?

 

sounds like u guys got a 6 for 9. what ecu r u running? sounds like an ls ecu but u said vtec kicks in?? hhmm might wanna listen more carefully for it..

What ecu are you using?
DEF hook up that second o2
My b16 still pulling hard at 7lk
redlines 8200

we're using the pr3 ecu? i think? on the cover its written b16 vtec-maybe it chipped? any more ideas?

 

Does it cut off at 7k when you try to rev it up there? If so, my guess would be that its chipped, ask the person you bought it from.

 

if you're speedometer and tach aren't hooked up it wont' work.

VTEC won't engage also if you're motor isn't warmed up. There's also another parameter for VTEC not to work, but it's slipping my mind at the current moment.

Oil Pressure.

we warmed up for 20mins then test drove, vtec engauges, if it was the oil pressure,vtec would not have come on, so we pulled over and tryed to rev it while parked it still does not rev pass 7k? i just dont know whats wrong?

 

What is the code written ON the ecu sticker, don't give us 'it says B16 on the ecu' . Importers do that to trick the people who don't know.

 

Like this yo, check if yours says like this. PR3

Thanks, appreciate it. I was racking my brain trying to remember earlier.

 

maybe he has an auto ecu?

Ooh, didn't know the auto ecu redlines at 7k.

OP, I mean when you rev up to 7k does it just kinda hover up there or does the fuel cut off(Bounce off the limiter)?

 

its chipped

yeah it bounces at 7200k, well i will go over his house and check the ecu again.
will the dizzy make it do that if its 180 degrees off?

 

i have the same problem with my crx with b16 swapped, my ecu reads:
37820-PR3-003
410-106089 AA
it's from an integra xsi, not sure if it's auto or not, bought a chipped ecu from ebay, problem solved

 

Most likely its the ecu then, I have no idea what would happen if the dizzy is 180 degrees off, I don't think it'll even run if it were 180 degrees off. Not to thread jack or anything but wouldn't it spark the pistons when it's at BDC if it were 180 degrees off?

that could be true. but here is the number on the ecu.. 37820-pr3-901-411-105197-ab this might be a auto. ecu? can someone check?

there is no way to check like that. You have to crack open the ECU and see if it has an Auto chip.

Yes there is.
Here's what I know:
88-91 ECUs (PM6, PR4, PW0, PR3, PM7):
5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00
Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80

And the dizzy can't be installed 180 off. Honda designed them that way so you can't install it 180 off.
Auto b16's redline -7200
Manual b16's -8200

 

So you do got an auto ecu, just go buy an mt ecu and its cool.

 

the stock pr3 that came with my swap redlined at 7200. everyone just told me it was because it was an old setup (manufactured in 1989)

 

there is no second o2 sensor

there is only one

figure out what the other plug goes to that you are talking about

OBD0 jdm b16's have 2 oxygen sensors
