Timing issue
 

I Have 99si so i have the obd2b-obd1 conversion Ive recently purchased Ectune. So i wanted to do things 100% correct i bought 1 of those digital timing lights to my suprise my car was runing extreamly retarded. With the distributor fully advanced i still had to add 12 deg to my tables to achive the needed 16deg btd. Ive heard of people advancing dizzy and retarding timing do gain a little edge on there bottom end im thinking its the conversion that has things runing funny. Has anyone else run into this problem the car feels great i def have throttle responce gains im just nervous about adding so much timing ontop of a fully advanced dizzy.

Re: Timing issue
 

lock belive i figured it out

Re: Timing issue
 

imho if you have the dizzy fully advanced something is wrong...check your mechanical timing

Re: Timing issue
 

that what is was b/c i had my head and deck milled the true tdc of my motor was a bout 4 deg late acording to my crank pully

Re: Timing issue
 

Two degrees off @ the cam (is four degrees @ the crank) is a LOT of deflection.

You need to lock your timing at 16 degrees, center your distributor, and adjust cam gears to get your engine into electrical AND mechanical time.

Re: Timing issue
 

thanks for the advice after driving around today i realized ---- is still wrong after doing small pulls only in vtec my car pulls enough vacume to enable fuel cut on decel. looks like ill be buying some cam gears. so do i put my motor in time mechanicly then adjust the cam gear for 16-deg btc do you suggest that i make new timing marks on the pully or do i try to make the others work im gunna post pics later so mabey if someone else has the same problem they can see.

Re: Timing issue
 

Why would you make new timing marks on your pulley when the existing ones are the ones you go by?

Re: Timing issue
 

b/c when i put the motor at tdc the notch on the pully is off about 2-4mm

Re: Timing issue
 

set your crank pulley to TDC via oil pump mark then align the cam gears correctly. As long as the head has not been milled and you are running a stock gasket the crank pulley will line up at the oil pump at the cam gears will center up perfectly. Once you have that done, adjust the distributor to the center and lock the timing via ectune and set the timing manually to whatever base timing you are running.

time for cam degree wheel

Re: Timing issue
 

Why? You only need a degree wheel with an aftermarket cam whose lobe center has nothing to do with stock cam alignment.

Re: Timing issue
 

hmm, news to me. How do you determine a engines cam timing which has been altered by milling without knowing exactly where to adjust the cams to? Maybe im just used to the OBD2 setup which has a crank timing gear with a magnetic pickup....so what you are telling him to do is line up the cam gears and forget that the crank pulley is not in time with the mark on the oil pump?

Re: Timing issue
 

Step back and think about it again. If you lock timing at 16 degrees, center the distributor, and adjust the (stock) cam(s)' adjustable gears until your timing light says 16 degrees then - holy ----! - you are in mechanical time. It is impossible to have a correctly timed stock cam engine and not have the distributor centered with the ignition timing correctly set.


PS - why do people on htuner think you are a big meanie pants?

Re: Timing issue
 

thanks for the explanation. I have yet the chance to use the ignition lock being that i am stilling running the OBD2 distributor setup.

because they have HUGE vagina's and cant take a blunt answer with a grain of salt. I like Mr. Cash to express my feelings. I'm still trying to figure out why being an "douchebag" aka ------- would exempt anyone from being an -------. I've always provided sound advice, in my opinion, and im not a noob to moderating. Most people from the "other forrums" dislike me solely because i am a moderator....oh well. Isnt going to phase me :)

Re: Timing issue
 

Look here, bitchtits, nobody wants a straight answer when they could get a warm fuzzy and an electronic blowjob. WTF is wrong with you?

Re: Timing issue
 

my sincere apologies. I forgot that internet forums replaced physical sex.

Re: Timing issue
 

by the way, i saw what you were talking about and made a post. I wonder how much more i can get out of them?

Re: Timing issue
 

Link please.

If you don't understand me then you don't come around here enough.

Re: Timing issue
 

i have 94 posts and have been a member for a few years. What does that tell you about my presence here?

I mostly lurked because i knew how many people disliked me. Now i just dont care so yea, i have no ------- clue what you are talking about their Mr. Davis.

Re: Timing issue
 

Why would anyone dislike you? You withstood the onslaught of 95% of HMT over your stance on HT without ever losing your cool. Don't agree with you, sure, but that's something different.

Re: Timing issue
 

i guess i will take that as a compliment.

Re: Timing issue
 

ok i understand what i need to do now im gunna pick up some gears tonight but how do i find if the motor is at 16btd if the notch on the pully is off which also has me thiniking how can that be off if b.c if the rods are the same length the rotation of the block wont change. so it should line up.

Re: Timing issue
 

What?

Re: Timing issue
 

JD thanks for helping me i have to inform you that im a total dumb ass i have the digital timing light i was doing everthing ass backwards. I didnt understand that i needed to put the light at 16btc and aim for the tdc mark so thats why i could never get it to match up cuz i had it at 16btc and was trying to hit that mark.

Re: Timing issue
 

I don't like timing lights with fancy dials or digital advance functions. They make n00bs think they have to screw with them, thereby screwing themselves on the deal. As a pretty bright guy with a rep for thinking out of the box I have to tell you... I can't think of a single ------- thing those adjustments are good for. I carry around a simple non-adjustable $30 Actron timing light, that's all you need.

With a non-adjustable gun, and timing locked in eCtune to 16 degrees, you adjust the cam gears to get the engine to go into ignition (and therefore mechanical) time. That means you line up the middle of the three marks on the crank pulley with the marks on the lower timing cover. :)

Re: Timing issue
 

yep thats what i was trying to do but this dumb ass digial light is differnt it sucks. here are the directions

To Set Intital timing push the up or down button until the idsplay shows the desired degrees of advance setting. View timing marks turn dizzy until moving mark is aligned with stationary 0 degree mark. then tighten. Thanks for the help though i seriously apreciate it.

Re: Timing issue
 

You can use your timing light just fine, set it to what you want and then you will use the lone mark on the crank pulley that denotes TDC, not the other middle mark in a group of three.

Like JD said though, ---- a digital light.

i finally set it i also got a good deal on some full race camegears 100 bux with a no slip warrenty
