sup guys i swaped a b16 into my civic a coiple weeks back and im having some serious bogging and breaking up problems before vtec. these are the things we have did to try to fix the problem. considering fuel we replaced the fuel pump with gsr fuel pump and the injector with gsr injectors and changed the fuel filter. we also put a new cap and rotor button. now im running out of things to change and im still get alot hole lot of bogging and the car is breaking up EXTREMLY bad at times. but when vtec comes in it seems to rev prttey good any suggestions im open to any at this point.

 

?!?!?!

 

What ecu r u running?

 

at the moment i ahve a 95 gsr ecu in the car before i had a b17 ecu

 

anyone any ideas

 

??????

 

Try and find a p30 ecu, or a chipped p28, I wouldnt use the gsr ecu on a b16a. Also test out the resistance on your coil.

 

are you thorwing any CEL codes? check your spark plugs, i remember my car bogging and breaking up really bad but as i got higher in the rpms it would feel fine.

 

well i was running the b17 ecu and it was doin the same. the plugs dont seem to be the problem cuz it keeps happen even with brand new plugs.

 

any check engine lights hows your oil pressure and timing. List everything you have done to fix it so far so we can narrow the problem down

 

ok so far we have we started out with fuel changed the fuel filter,pump,and injeectors. then we change the cap and rotor button on the dist. i was also running the b17 ecu so we changed it out and put the b18c1 ecu in. the b18c1 ecu seems to help it run better because vtec somes in sooner and picks up the bogging some but the bogging is most defenly there.

with the b17 ecu i had 3 lights fuel system supply, vtec pressure, and o2 sensor. but after we changed the ecu to the b18c1 and changed the pump at the same time i havent had any codes at all

 

Have u done a leak down and/or comp test what about ur oil pressure is it ok low oil pressure would cause the vtec code.

 

im having the same problem with my car. i swaped in a B16 and the cars not moving untill vtec, but for some reason when im on hills the idle drops and sometimes dies, i thought it was fuel related as well so i went out and bought a Walbro fuel pump ( Not installed yet ) and i also changed my Sparkplug wires and notice it kinda stoped a little. the other day i put in a FPR it was set kinda high 65-70psi car ran nice for awhile but i took it back out cuz i couldnt set it lower. for some reason i notice when i 1st start the car is worse. after about a good 30mins to an hour of driving its not really there as much, not to sure how to read the codes but im gunna check it out

BTW i had my timing belt changed not to long ago and my boy that did it said theres something wrong with my Map sensor i swaped it out for a LS Map but didnt seem to help

almost forgot if my dizzy isnt advanced the car runs worse.. i have it as much as it can go

UPDATE...

Changed the fuel pump to a 255 still it didnt work then i figgured out it was the MAIN RELAY, changed that and droped the 255 back in and now its a beast...
