odd timing.

[240sex]

so i was reading that sr’s timing is supposed to be around 15 degrees BTDC. so i was just doing some general check ups and decided to check the timing. so i get it all hooked up, and at idle (around 850RPM) the needle was probably between 25-30 degrees BTDC (if the markers kept going). so i lowered it down to 15 BTDC, and took it for a spin and it barely ran and was SUPER sluggish if i put force into it. just sputtered like crazy. so i putted back to my house and put it back to where it was and took it for a spin, and it ran perfect.

i took the spark plug out and checked to make sure TDC was on the mark it’s supposed to be, and it was.

i guess i’m just asking if anybody else has noticed this same thing with their sr and having the timing up much further?

maybe its running a higher boost so the timing was changed to compinsate

if it ant broke…

as far as i know it’s running stock boost (7’ish psi). it weird, but it’s definately not hurting my car with it being that high.

On some cars there is a timing “check connector” that you need to disconnect to set base timing. ECU controls your ignition timing.
Not sure on SR’s how ever.

heh

are you reading the right markings?

@spd-dmn

definately. 6 markings. -5, 0, 5 , 10, 15, 20.

i took out number one spark plug and checked TDC, and it’s bang on the zero mark.

Did you disconnect the TPS?

[87s15lt1]

thats part of the procedure for a KA, same for SR?

[face]

Yes.

[87s15lt1]

Good to know…

[240sex]

Apparently the only reason to unplug the tps is to steady the idle, but my idle was steady anyways so there was no need.

your crank sensor may be out a few teeth. you may have to set the timing mark of your cam gear and c.a.s. gear.
