When installing a performance chip, most of the times it is required that the distributor ignition timing be at the stock setting. This is brought here, because prior to installing a chip, many car owners, often do a manual timing advance (global setting) in an attempt to make more power out of the engine. Other times, it is caused because of a mechanical fix that required removal of the ignition assembly and it is left unadjusted when it is installed back.

This should be reverted if a performance chip is used, since the chip advance timing in various points by itself already and adding any extra manual advance will possibly result in dangerous detonations, also known as engine pinging or pre-ignition. This, could be very destructive for the engine at high speeds.

Here are some tables showing the stock setting of some Honda cars that are chipped often.

93-95 Honda Prelude Ignition Timing Adjustment

For doing the adjustment on Prelude, you will need a timing light. The car must first be warmed up until the fan turns on. Timing marks for timing light are exposed by removing the rubber cap from inspection window on the cylinder block, by the bell housing. Also, the ignition timing check connector must be jumped. It is located under center of dash. See the drawing below for its location.

Connect jumper wire between the Blue/White and Brown/White wire terminals.

To adjust timing, loosen distributor hold-down bolts and turn distributor housing counterclockwise to advance or clockwise to retard timing. Align the pointer with the Red timing mark.

When the job is done, tighten the distributor bolts to 16 ft. lbs. (22 N.m). and recheck timing.

If it is all OK, remove the jumper from the ignition timing check connector. Reinstall the cap into inspection window on the cylinder block.

94-95 Honda Accord Ignition Timing Adjustment

Adjustment for the Accord is similar to the Prelude described above, with exception that timing marks are located on the timing belt cover itself and the service connector is located somewhere else. It is located under the glove compartment, as shown below:

92-95 Civic Ignition Timing Adjustment

Again, the Civic procedure is no different from the two above. As in the Accord, ignition timing marks are located on the timing belt cover itself. The ignition check connector is located different. You will find it on the right side (passenger’s side) kick panel, near the ecu. Check the drawing below for location:

Here are the timing marks on the 1992 – 1995 Honda Accord:


1992 - 1995 Honda Accord Ignition Marks

On the above picture, the red mark is 15 degrees BTDC, while the white mark is TDC (0 degrees BTDC). If colors are faded, you may clean the area from dirt and/or grease and highlight each with white and red chalk, so it shines through the timing light. Remember that the last mark at the right should be the white one (TDC).

Great info! This has everything I needed to know to check the timing. Well, except for one minor detail. It would be very helpful, if you could show a graphic of where the inspection window is located. I can’t find it. And no timing marks show up when checking the timing from other angles. I have a 94 honda accord ex

Hello Henry. The window part is for the Prelude. Your Accord should have the timing pointer on the timing belt cover, unless it is broken or not present for any reason.

Actually, the last picture on the article is from a 1994-1995 Accord. Yours should be similar. Anyway, I will do some research. If I find something will post a comment here.

Best regards and thanks for writing.

Hello Juan, welcome to this blog.

I am afraid that I did not fully understand your question. If by OBD 1 you are referring to the data link or diagnostic connector, it is located behind the glove compartment and has three wires.

If it is not what you are looking for, please let me know.

Have 94 Civic EX. Had to replace the distributor on the car. On setting the timing… Do I set it right on TDC or the 16 degree mark (RED) mark as shown on your sketch?

October 11, 2009

Hello Gilbert.

You should use the red mark. At idle, it must align with the pointer, provided that you already warmed up the engine and jumped the service connector. If it doesn’t align, then you should loosen the distributor to adjust until the red mark aligns. If there are three red marks, try to align the center one. The other two are maximum and minimum accepted alignments.
