spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

ok.
d16z6 in a 1990 civic

fully converted to obd1

Car runs alright. pulls decent. But it seems to be spuddering at high rpms. Like if i rev it real high, then shift into 4th and give it gas it will spudder/bog. Almost as if its detonation. But the I double checked cam timing and ignition timing is good. However, in order for the ignition timing for be lined up, the dizzy has to be rotated all the way towards the bumper. I did jump the service connecter when i did ignition timing also. Any help will be greatly appriciated. Thanks.

I have a turbo kit sitting in my room waiting to get put on. I just need to figure this problem out first.



if you can lead to the problem ill paypal you 5$. ive been trying to fix it for a while.

Make sure the engine's warmed up completely before setting distributor timing. Once it warms up and the idle drops, then jump the service connector (which pretty much just eliminates the chances of the iacv opening up and jumping the rpm...which in turn jumps the timing) and set your base timing. What's your setup? Unless you're using an obd0 head the dizzy should sit somewhere in the normal "centered" location.

i have the car warmed up completely than jump the service connecter. in order for the dizzy timing to be on you have to have the dizzy rotated all the way towards the front of the car. i am stumped. I am running a non vtec ecu with the d16z6 but thats because my p28 is chipped for boost already with a basemap. Would running a p06 with a z6 cause this maybe??

What distributor are you using. If your using the a6 dizzy that's normal, if your using a z6, your timing is off or 180 degrees off. Is vtech hooked up. if so your running lean up top.
Do you have an FPR? increase the fuel pressure a little.
hows plugs, wires, cap rotor?

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

how can it be 180 degrees off? There is a notch in the dizzy so it cant go in 180 degrees off. Its a z6 dizzy. vtec isnt working cause its a p06. i dont think it would cause spuddering.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypa
 

You can't use an a6 dizzy on obd1. It is very possible that since vtec isn't working, it's enrichening too much on the high cam setting causing it to sputter. You should really get vtec working first and see what happens.

Sorry...clicked post accidently...I edited it.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypa
 

your timing has to be off if your pointing it all the way the firwall. cause normally it's in the center.

The z6 cam gear doesn't allign to 12 o clock. there's a notch on the cover behind it at about 7 o clock and a notch in the cam gear at about 6o clock or whatever (not the two center notches) that have to be alligned. not the 12 o clock side notches to the head surface.

how your ignition, plugs, etc.? Tighten your spark plug gap a little, you might have high rpm blow out

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

what do you mean by high rpm blow out?? And can you explain the cam timing. i dont understand what you are trying to say. When i did mechainical timing i lined up the line on the crank pulley, and put the cam gear at tdc by lining up the two lines with the head deck surface and the tdc mark at the top.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypa
 

HOW IS YOUR IGNITION: PLUGS, CAP, ROTOR, ETC?????

blow out is simply something blowing out the spark, ethier fuel or something. To much exposed increasing resistence or whatever. Doen't hurt, but if it only at high rpms it might be it.

if you look at the cam gear there's 3 notched on it. the two side ones and another beneath the left side one. that notch need to be lined up with the mark on the plastic cover behind the cam gear. theres a pointer that it lines up to on the cover at about the 7 o clock position. Go adjust it to that. take out the dizzy, face the rotor to the number 1 cap terminal and put it back in.

He should only have to worry about spark blow-out if he's boosted...usually around the 8psi mark it tends to "blow-out" the flame. I'm willing to bet it's because you're trying to rev your motor up to normal vtec area...above the 4500 rpm range...and the ecu might think it's in vtec when it's actually not, therefore adjusting timing and fuel towards the hi-cam curve. Of course that's if the p06 is setup for running vtec with the sensors turned off.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypa
 

The plugs could have been gap inproperaly or there shitty plugs.

I'm guessing the p06 isn't setup for vtec, cause he said he has a chipped p28.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

im running n/a. i just put in the po6 to get the car running after the z6 and obd1 swap. i will double check cam timing and let you guys know how it turns out. if info i got from anyone ends up being answer ill paypal 5. keep the opinions rolling though. Thanks

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

and the p06 isnt setup for vtec. so the car would be running on low cam all the time. not sure if that could cause spuddering though.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

No that wouldn't cause spuddering. it'll run fine on the low cam. You have something wrong with the way your checking your timing and possibly mechanical timing but I doubt that if you had mech timing off you'd have bent valves.

But I'll forget about timing for a second. the spuddering is a cylinder/cylinders not firing, Just check regular maintenance things like distributor cap rotor button and plug wires.

If the car will spudder by reving the motor while your not moving. Just make it do it then start pulling plug wires one at a time until you find the one that doesn't make a change in how the car sounds. then you'll know the cylinder with the problem.

If it only does it while driving make it do it turn off the key coast into a parking lot or something and pull your plugs find the one thats differant then check everything going to that cylinder plug, plugwire. crud in the plug to the distributer.

and just maybe the injector clogged to that cylinder.

Im sure your have your timing wrong though. So try looking at that some more. maybe even reburn your bin and see if that fixes it. could be a funky burn.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

yeah definately check the ignition stuff first, esp. plug gap. I had a bad IAT wire once and it totally fucked up my mixture up top and caused sputtering because it was putting out the flame so maybe because you're not using the right ecu your fuel mixture is off combined with a shitty plug gap. Are you sure you have your plug wires in the right holes if you need to move the dizz so far to get it in time?

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

the ecu isnt chipped. its not like horrible sputtering. motor actually runs pretty good even tho its in low cam all the time. it just sounds as if the car is held back. Like the motor needs to clear its throat. hah. like when i stay on the gas it doesnt sound too bad but when i am rolling in 4th than give it gas it kind of sputters/ bogs. ---- sucks. i wanna boost this nignog but i need to fix this problem first.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

Check the timing on the p06 burn...sounds like the issue I was having with BRE and my modified n/a basemap.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

the ecu is virgin.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

Why don't you hook up the p28 and try that? Honestly you should have your car setup with the motor and ecu combo you want to run when boosted first, make sure all the bugs and issues are worked out, and then boost it.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

thats what i am doing. comprehending owns you. I did a z6 swap. BEFORE I BOOST, i need to fix this issue.

Re: spudder issues. Fix this so i can put my turbo kit on! u fix it get 5$ paypal.
 

Go rent a timing light, if your car feels like it's being held back at high rpm it's because it's a vtec head and you're running low cam all the time, it's a stock cam, it's optimised for low rpm operation -- airflow up top is gonna suck.
