hey guys

i swapped b16 out of an sir into my eg, and the motor runs really strong and gets great gas mileage. the only problem im having is that the engine feels like it hits a rev limit at 7k. it pulls strong but when it gets to 7k it falls flat on its face.

i don't know what to do about it, the ignition system is functioning properly, new plugs, wires rotor and cap. i replaced the fuel pump before the swap, its an autozone pump for a civic si. when it cuts off it kind of feels like a fuel problem, but i don't know. the car has fuel pressure at idle.

vtec engages fine, and the car runs great. I've got a b16 with the trans that came out of the sir, and the p30 ecu from the sir also.

i don't know if anyone has ever run into this before, i don't know what's going on here. i'm running out of ideas.

thanks guys

i got that problem too... along with my cel problem... lol i was told to get an sirII gauge cluster and it would be fixed... but would make no sense cuz my friend did this same swap and everything worked fine.

 

what ecu are you running?

 

p30

 

i was told that my tach could be off, but i think it's kind of unlikely that it would be off by 1k at 7.

i let you know if i find out anything. this is really pissing me off, and i need to take this thing to the track before it gets too cold.

i don't think the tach is off by that much, because vtec still comes on around 5300, which im pretty sure is when it is supposed to

 

what kind of cel problem are you having?

 

fixed the tach problem... iono how tho. wired up the knock sensor and all wires. and now my motor doesnt stop at 7000 rpm it goes to 8200. so fixed that. as for the CEL i have no idea what im throwin. is there a way to tell without running a diagnostics test?

 

http://tech.hybridgarage.com/t...6Aeg6 there are all the wires. dono if u have wired them yet or not but there u go.

 

im throwing codes 21 and 23 dont understand... vtec works.... n e help?

 

i believe that's a vtec solenoid and knock sensor, not sure though.

im assuming you had to wire at least the knock sensor, and possibly the vtec solenoid. check to make sure those circuits are continuous.

i'm starting to think we both may have ecu problems.

 

starting to think mayb we both have automatic ecu?

Could have been an intermittant problem, reset ECU and see if CEL comes on again and still indicated both codes. If your ECUs were auto you would throw some codes (19, 30, 31 maybe others can't remember) for the auto BS. But just to confirm check this link

reset ecu? what u mean? just unhook the negative wire?

 

That would work, or remove the Back-Up fuse in the under-hood fuse box. This will wipe the ECUs ROM of any stored codes. If the CEL doesn't come on shortly after starting the car most likely it was an intermittant problem.

I have a similar problem, idk what it is!!

 

my rev limiter is fine now i can go all the way to 8200 and pulls through. problem is i couldnt tell u what i did haha one day it was stopn at 7 the next day went to 8200. next.. reset my ecu but engine code still comes on.... so i just orderd a skunk 2 ecu
