Timing Question
 

Hey all. I'm having some trouble setting timing. I've checked the base and all of the marks are lining up perfectly. When i use the timing light i can't get the marks to line up and the distributor is turned all the way. The idle is about 800 rpm.

Would a basemap retard timing at idle? Should i put in my stock injectors and run the stock ecu to set timing? I still have to get my IAT sensor in, would that throw off timing? I'm trying to get everything set for getting it tuned and this is the only thing that is giving me trouble.

The engine is a D16y8. I'm running off a p28 ecu with a crome basemap and 450cc injectors.

Re: Timing Question
 

what kind of timing light are you using if its the digital set the number for the deg of timing you need then aim for the the TDC mark.

Re: Timing Question
 

Here I'll give you my y8 tune. I don't feel like explaining y8 timing right now.

Re: Timing Question
 

Is this a Y8 with 450cc Dennis?

Re: Timing Question
 

I plan on having you do my tune Chris. Is this something that I need to have resolved before tuning? Or could you fix this issue during the process?

Re: Timing Question
 

I never understood the y8 timing dilemma. If you're unable to physically sync timing to the map, just offset the map and make a note of it.

Re: Timing Question
 

Set idle timing to 12 degrees (that's where your timing mark is on the D16Y, not 16 degrees like earlier D-series) and accept the fact that with OBD1 your distributor will have to be cranked all the way one direction because D16Y are "made funny."

There is a small chance that, if the engine has been milled/decked, that you won't be able to quite get it into timing. You need a cam gear at that point. However, if this happens, it is MUCH more likely that you have a lower timing cover and a crank pulley that aren't off of the same exact engine. 20-40% of D-series I see have the wrong pulley, and it throws a timing light off.

Re: Timing Question
 

make up your mind is it 20 or 40?
for fucks sake.

Re: Timing Question
 

If you're using a dial-back timing light on the TDC marks (JD's favorite), then you dont need to worry about what crank pulley is on there. Â

Re: Timing Question
 

I was asking the guy above you who posted.

yes, i would prefer that you make sure the motor is timed before bringing it in...just to make sure there are no mechanical issues (timing belt, distributor issues, etc).

My advice, take a Crome map, set ALL of the values in the low cam timing map to 22 degrees....every value, get the car warmed up all the way. Put the distributor in the middle, and use a timing light and synch to the 12 degree mark on the crank pulley. If you can get it close to that mark....yur good. Oh, and listen to JD, whenever I have D-series questions I call him 1st :)

Re: Timing Question
 

Wrong. The marks on the timing cover are specific to the crank pulley that rested against that cover from the factory.

There's a 2 degree timing difference between A6 and Z6 cover/pulley combos, and that's the CLOSEST any combo I know of comes to being in alignment.

Re: Timing Question
 

A mismatched cover/pulley puts the TDC mark out? Didnt know that. Thanks.
Stethoscope FTW, to ensure a non-grenaded motor.

Re: Timing Question
 

Yeah with 450's... How I set the timing on this one was ,start with stock p2p maps then add 8 degrees acrossed the entire base and then synced the distributor to the mark on the crank at 12degrees in crome. After that while tuning I actually advanced the timing even more almost everwhere. my timing maps have some wierd looking numbers like 11 degrees final timing at 11psi. but hey it runs great and the plugs look good. I took like two weeks datalogging and making changes to and from work so it's really smooth running.

Re: Timing Question
 

Dude to tell you the truth synching timing doesn't even matter. Half the junk I get the pleasure of tunning has a shiny ebay crank pulley on it with no marks anyway. I just go by feel being carefull turning the boost up in steps and really checking plugs. I hate tuning these crap mobiles. I'm getting to the point where I don't answer phone calls for tunes anymore.

I wish I could get sweet cars like you all do. LOL I'm lucky if I get the guy to spring for the a couple $8 dollar sets of spark plugs. Anymore I focus on my own cars and thinking of ways to get Dave to let me hang around him more.

Re: Timing Question
 

I cant remember the last time I worked on a car that had an aftermarket pulley. Luck I guess.
Syncing timing is a habit for me. Plus, you're able to tell them that the next time they have the dizzy off or do engine work, to set timing to 16* and everything will be ok.

Re: Timing Question
 

Telling them that doesn't mean anything of the sort. A lot of these kids don't know how to use a timing light... but you know this if you know why I hate the timing advance lights. :l

Re: Timing Question
 

Man I agree with everything you just said. For me it's been that stupid ebay pulley 90% of the time. The last car I tuned I showed up the car had no timing marks to use and the guy had no new plugs I had a moment there were I could feel it I lost the love. I like to do a really good and thorough job on a tune and it's just not fun when you don't have a few simple things you need to get it done.

Re: Timing Question
 

Okay, why do you hate advance lights?

Re: Timing Question
 

is that the proper way to fix the fuckered up timing with the p2p timing map? i had a bitch of a time trying to figure out the timing a few years back. got it ok but always knew it could have been better.

Re: Timing Question
 

Run race gas and dont give a ---- what ur timings set at :6

Re: Timing Question
 

old craftsman timing light FTW :6

So bisquick did you try my .bin?

Re: Timing Question
 

I have to order a chip burner. :'( I downloaded crome and started messing around with it. I'm a complete tuning nube...

Re: Timing Question
 

Anyone have a good deal on a willems burner? ;D

Re: Timing Question
 

Do not get a willhelm burner. Get a Burn2 it can link with crome and burn the chip right from the program even on crome free. If you have a zif socket you can work two chips one in the ecu and one ready to be burned. you can chip tune fairly quickly.

Thanks for all your help ;)
