advance timing

[Kid Racer]

Hey guys what dagree of advance timing should I do..I thinks its 14 but I could be wrong...

another classic in the making...


its a old motor no particular number is going to be best for you. you just have to listen to the car and really just feel out the best spot...

yup thats what i did with my turd gen. start out around 10 degrees and run that sucka at wot. if it didnt ping, id advance her some more!!

if you knew what a dial back timing light was and even knew how too use it than the correct way would be to set the timing at 38* at around 3000 RPMs than see if it pings if not add 2* each time you re set the timing till you start to get pinging than back it up 2* and that would be the most advance you can add to the car -- worn motors and race type compression allows more timing than a stock set up - giving to the fact you can change the timing in the first place being a non computer car -- jz

What motor? what car? If is the new car you just got the only way to properly change the timing in throught the prom. Other wise you will screwing with the tables that are programed in the prom. The intitial setting for the dist. IIRC should be 6 deg befor TDC. This is if its for the TPI car you have.

All you can so is set static timing, the ecm does the rest. I never messed with TPI setups much, but the other EST cars I messed with only liked a few degrees advance of past what GM called for.

You are right, its 6 degrees advanced...

However, if this is that TPI car, you aren't screwing with any tables (they haven't changed at all), you are just making the computer more blind than it already is. The tables are calibrated for the thing to be at 5.98 degrees advanced, so by you advancing the distributor, you are lying to the computer. The computer thinks its at 6 degrees, so at WOT lets say the table calls for 29 degrees, well considering you have added 8 more, you are now at 37 degrees instead when the computer thinks you are running at 29. If I were you I would leave it stock (at 6), if you want more timing in it at WOT and even cruising, idle, wherever...spend some money and have someone tune it...otherwise you could end up causing major issues that could cause the demise of that engine.

not to be that guy, but i never had any problems with advancing the timing in my old turd gen tbi car. disconnect the ESC wire or whatever it was called, bump it up some, plug back in , run it down the road, see if it pings or not, Gtech it (it was accurate!) and see what if i'd improve or not. i think i was 10 or 12 degrees advanced and it was a different machine than when it was set to stock im sure its different than a tpi car, but this was my personal experience with it. same thing goes with a 93 dodge caravan i used to have. lol hondas couldnt hang

yep, its different than a tpi car...

haha cool then technically im not being "that guy"!
