I bought a 1993 civic ex with a 94 b18b1 motor in it with hydro tranny. I used to have a 97 dx with a single overhead cam. On my single when i would take off in first and slam into 2nd i would spin the tires a bit, but with the new ex with b18b motor in it, when i take off in first and dump into 2nd, i downt spin tires at all, it just takes off slowly almost as if it was restricted in some way. My brother in law has a 94 civic bubble with the same motor in it, we both have open exhaust with no cat, but the only difference is he has a header on it. But when i drive his car it just feels quicker, and when i dump 2nd gear his tires spin like crazy. Even when were racing he sometimes just launches on me in 2nd 3rd and 4th gear when were on the hight way. I just feel like mine is losing power somewhere. It runs great, never backfires or anything like that, just seems slower than it should. Any ideas where to start, ive heard maybe clutch is going but i dont know, it catches higher up than my brothers does. Please help

 

What kind of ECU are you running?

when did you last change your plugs/wires/rotor/dizzycap?

how wide are your tires?

Need some more details other than "Its slower than my bros"

 

its a ecu for a b16a2, i was told it makes it run faster than the ls ecu, dont know the truth to that. i have the 15" swirlies, i dont know exactly how wide but stock size, and i have not replaced anything on it yet, i just bought it a few weeks ago.

You were told incorrectly,
A) your motor doesn't have Vtec so the fuel mapping is all kinds of screwed up
B) your motor has a much larger displacement than a B16, causing your fuel mapping to be all kinds of screwed up
C) you may have already damaged your engine running that ECU

So long story short, Buy a B18B1 ECU and watch how much faster your car will be.

Oh, and I hope you haven't been reving up to the 8200RPM redline of the B16 ECU because that is a sure-fire way to destroy an LS engine that was never designed to get much past 7000.

 

not at all, i been keeping it down around 6300 at the most, i will swap the ecu thanks

 

who told you that a b16 ecu on a stock ls motor will make it run better? they should quit messing with hondas.

LOL

 

see ive never been involved with the ls motor, i turbo'd my d16 on the other civic. the guy who i got this car off of said it makes it run faster so i believed him but unfortunately shouldnt have. i just gotta find someone with a ls computer they are looking to part with. i appreciate the help

 

chipped p75 FTW!!!!

Tell whoever told you that to end himself/herself.

Now, that you got correct info on here, good luck!

 

Hello i got same trouble with my engine, i got a Honda civic hatch 92' swap b18b1 from 94' teg, Mine is when is on 2nd shift full throttle i loss power sounds like its drowning or something, and it more often happen on the 3rd gear full throttle? my ecu is the stock one (complete swap) dc header, staright pipe,16's rims 205/45 tire, aem 2.5 short ram intake, E3 spark plugs (new) It affects a lot when i do it on track , runs 16.15 on a 1/4 mile . please needs help
Thanks....

 

I have a 99 b18b1 integgy and i started to back ire after i changed the oil pan gasket. So the common thing i did was change the spark plugs and spark wires as well as the rotor, but after all that i still backfire.... what can it be.?.

 

change the ecu for sure.. also what transmission are you running? an ls trans right? the guy with the hatch probly has a gsr or b16 trans, i have a b18b1 in my coupe with a gsr trans and it pulls a hell of a lot harder than with the stock tranny

 

Run the p75 ecu
