timing issue?!? what is the stock base timing for a 92 z28 and what do I have to disconnect before I do this and where is it located? need to know as soon as possible! thanks |
Re: timing issue?!? disconnect the EST wire and I believe the stock settings are *12 |
Re: timing issue?!? Where is the est disconnect? I can't find it |
Re: timing issue?!? it is a single tan colored wire located near the blower motor on the passenger side of the eingine and the proper stock timing is 8 or 10 but while you have the EST wire disconnected it should be set at 6 |
Re: timing issue?!? Is it out In the open and easily seen or is it in a wiring harness hidden well? Hopefully I can find it and set the timing correctly |
Re: timing issue?!? it should be a single tan wire connector should be relatively easy to see and reach disconnect it after letting the car run to get the operating temp then set timing to 6 while the wire is disconnected turn the car off and reconnect the wire it should be set perfect then the timing may jump from 6 to 8 but that is not a bad thing |
Re: timing issue?!? is this correct? i thought it was 10*BDTC? |
Re: timing issue?!? The stock setting is 6 BTDC. TPI engines seem to run better at 8 to 10 BTDC. |

Re: timing issue?!? The 6 is to the left of the zero the est wire comes out of the wire loom somewhere between the a/c unit and the distributor, its a tan wire with a black weatherpac connector on it. |

Re: timing issue?!? First of all 0 degrees is the biggest dip, the center of a "v". the next one above it is 6 degrees. |

Re: timing issue?!? Evilemokid94, BTDC means before top dead center. Top dead center is the zero mark. |

Re: timing issue?!? 1 Attachment(s) I do it with a zippo sometimes, works great! But, in actuality, yes, you need a timing light. You will not be able to get it set correctly without one. The EST connector is here ---------VAttachment 391548 |
Re: timing issue?!? i got it, didnt need the light :], just adjusted the dizzy with it running, now it runs great!! idles fixed!! |
