ok so heres what happened, i did a dpi to mpfi swap in my ef and my timing is retarded 4 degrees. So i tried to advance the timing and it won't rev high enough. Also when i advance it to even 0 degrees it sounds as if its hitting the rev limiter, although its the original ecu. My friend said if i put the the original cam gear it would probably run fine. Also i just want to say that i have a d16a6 from the d15b2 with an aem cam gear, and i was told it might be from an eg d16 so just trying to give as much info as possible. And thanks alot for the help

 

When you say original ECU, you mean one from an Si right? Not the on before the MPFI swap?

 

yes the si ecu i'm possitive

 

mine does the same thing. i narrowed it down to the cam gear timing and/or the cps in the dizzy.

is it slower than it should be and has too much intake noise?

 

When you did the timing, did you use the side marks ( - - ) or the / on on the cover?

 

yeah exactly thats my problem to a t

 

my friend larry did it and he's chaned his timing all the time so i don't believe that would be my problem. But thanks for the thought, just one less thing it could be right

 

Yea.

Does the tach bounce around alot when you get up there? I had this on my ZC, the ignitor was dead. Can you try a diff dizzy?

 

will any d16 or d15 distributor work or could does it half to be the d16a6 distributor

 

From what I've read, a MPFI distributor only. But I've only done the swap to a ZC ( not mine).

Maybe somebody else can back me up.

 

retard the cam timing a little bit and it will raise the power band, and try another dizzy. i got mine from here for $25 and its bad, but i still drive it. it runs like **** after 5k but its still faster than dual point.

 

can it hurt the engine to run it retarded that much

 

bump

 

long term, yeah. but no big deal to use it in the mean time for transportation.

 

so what everyone is saying basicly is if i replace my entire distributor it will be fine right. Also after getting another distributor what should i rum my timing at. and does any one know if you use an aem cam gear from a 92-95 sohc civic if theres a difference. any and all help and opinions are apreciated

 

your tps sensor is probably in need of adjustment. if its bad or needs to be set you wont be able to rev very high.

4 degres? no, unless you have a huge cam, high compression pistons, and a milled *** head. But at that point you wouldn't be on street pump gas.

 

how do i adjust my tps sensor

 

anyone

 

Are you sure you swapped the wires on the distributer plugs right?? Or the connections at the ecu??

 

yeah i believe so

 

also i replaced my entire distributor with no change what so ever, although i was reading in my manual and it says it could be the fuel filter and opinions on this as the source of my problem

 

i went out and purchased a new fuel filter thinking this would solve my problem i will respond with the answer asap
