My chilton manual says start the car, let it warm up until normal operating temp( so the cooling fans kick on at least once) turn ignition off. Jump service connecter,start car, check/adjust timing,retighten the bolts if you had to adjust it, turn off car,remove jumper, start and re-check( i have know idea where it would be in your 94 hatch, do you have a manual for your hatch?, did the B or D series engine before require you to jump a service connector? You might ask around in the civic forum. Good luck man, my 94 lude still does the damn bogging and my timing is within spec.

yea pretty much - anything to create a short or jump... i use a little terminal connector - not the ones with a full loop like =0 but the ones that are open, like =C . I insert the C portion into the service connector and it provides the jump - it's much easier than trying to fandangle a paperclip or small wire into it and have it stay there.

and yea you were right in your initial post - the service connector is jumped so that the ecu does not compensate for the timing changes you make. if the two shops you took your car to, didn't have the service connector jumped - they did not particularly achieve anything, except possibly making your timing worse (:

i've helped out another guy on here, who had a swapped h22a in a civic or accord or something, and he didn't have the service connector seeing as it was a swapped into his civic. - if you search you might be able to find it - as It gives the pins from the ecu you would have to short to achieve the same thing...

best of luck.

It's pretty much blue if it's a honda. (I haven't seen any other color) and it's almost always under the passenger dash panel or right behind the stereo. It's a blue plastic clip that isn't plugged into anything. (The service jumper from honda is what it plugs into when you want to read a code. $6 at honda if you want to order one)

OR...... Check your timing. Turn car off. adjust distributor advanced or retarded, whichever needs to happen, then Start it up and see how far you went. Kinda retarted and time consuming, but it will do more than nothing if you can't find the service conn. but please, just look under the dash for it. - go to a honda dealer, go to the parts department and ask them to pull up the location of the service connector. Shouldn't be a problem.

Hi guys

sorry if this is a dumb question but i have searched. When you say adjust the distributor how is this done. From my searching i gather that you rotate one way to advance and the other to retard. But which way is which and i cant see how it can rotate (just by looking at it)

any help much appreciated

 

I'm not sure if the connector that you pull ECU codes from is the same as the connector that you jump to do the timing. I say this because on a 3rd gen lude, the connector for timing is in the engine bay on the pass side firewall. Of course, you don't need to jump a connector on a 3rd gen to get the ecu codes. The codes are flashed on an LED on the ECU itself.

Here's what it looks like on a 3rd gen lude. I still have this connector on my H22 swapped 3rd gen so I assume where ever this was on your car before the swap is where it should still be at. Does anyone know for sure though?


As for adusting the timing, there should be 3 10mm or 12mm (I can't remember which but I think 12mm) bolts that need to be loosened. If you remove them, the dizzy would be able to be removed. Once loosened, you can rotate the top toward the firewall to advance or the opposite to retard.

yea on a 4th gen prelude with p13 ecu, according to the helm's page 23-93 - it is the service connector that you jump, located in the center console on the interior of the vehicle.

to the fella above looking to advance/retard your timing - if you have a 5th gen I believe the timing is controlled electronically so you can't physically adjust it (someone correct me if i'm wrong) - 4th gen owners have slotted dizzy bolt holes so they can move it back and forth for timing.
