Proper Ignition Timing?

88fivepointoh · 04-30-2003, 09:05 PM

I have made an appointment with my ford deal to set the timing on my car. where should I have them set my timing to? I am running the F-303 cam. i heard 12 degrees is the max but also heard guys running more advance?

Well there is really no set timing for any car. The best way to set the timing is to mess around with it until u get the car to run perfect.

go to walmart and or sears or somewhere and buy a 30 dollar timing light and do it yourself... it's one of those things that's really reasy to do.... tehcnicaly the car's stock timing was 10* I think.... I'm at about 16....

Most wind up between 13-16 degrees advanced.

Thanks guys.. I have been fighting with my car for a while on timing and fuel issues.. I have a code 41 now that means lean mixture at all times with no change. I have a 155lph fuel pump, AFR set at 40lbs with line off and still lean as can be.. my plugs look like i never fired the car up. I also have a code 67 engine tempurate out of range.. I have the 160 degree thermostate in my car. could that be causing my lean condition?

drtbiker · 05-01-2003, 07:29 PM

yeah i would deffiently change the t-state to at least a 180, the car is not getting a chance to warm up....

180 is as low as I would go.

88fivepointoh · 05-01-2003, 09:31 PM

ok I will pick up a 180 first thing in the morning.. do you think that would cause a lean condition? i would think i would be running rich but the ECC-IV is a crazy machine..

What mods have you done to your car?

First I would throw out that 160* stat. It's not allowing the car to get up to the proper operating temp! I have a 1958 stat and it has worked the best out of any other temp stat I have used.

When you got the code 67, how did you go about doing that? KOEO, KOER? Was the engine cold, or warmed up?

When I bought my adjustable FPR, the instructions said that the stock regulator is set at 43psi, but I had always thought it was 40psi. At any rate I would try upping the fuel pressure out of the regulator some more. I have mine set at 46psi at the moment and it definitely helped keep my top end from falling off.

Oh and I have my timing set at 15*.

I got code 67 after reseting the computer and running the car around the block hard and idleing and everything fully warmed up to its potential with that stat... I plan on getting rid of that stat this weekend. this is what i have done to my car. trickflow upper and lower, 65mm TB with spacer, F cam, 1.6 to 1 roller rockers, equal length headers, h-pipe, flows, msd coil, holley anihalator TFi module, #24 injectors with pro-m 75mm mass air, bbk 155lph fuel pump, k&n, A3M1 ECU, etc. i have thefuel set to 40lbs with vaccum off. maybe i should raise it to 45 but i heard guys with drivability problems.. but then again every car is different. could that stat cause my code 41 lean fuel constant?

I would go with an edelbrock HP or other quality aftermarket thermo @ 180 deg. By paying a few bucks more, you will get an accurate thermo with a larger mouth for more flow when open. It is amazing how different parts store thermos can be with regard to advertised temp vs. actual opening temp. I have tried several and also tested my Edelbrock on the stove in a pot of hot water with a baking thermometer. You may also like to swap out the 155lph to a nice 190 or even 255. Your pump may not be providing its advertised flow at higher RPMs when the pressure rises on the reg. If you install a FP gauge (I recommend an Autometer electric running off the schrader port), you will know for sure where you stand and it will serve you well moving forward.
