Hi Everyone,

I have a Suzuki Turbo 660; 6 valve; EFI; manual transmission. I recently replaced my distributor and I think my ignition timing is off because when I try to accelerate from a complete stop, my car seems to shake before it takes off. My idle speed is at 800 rpm and it does not hesitate when my car has already taken off.

I wanted to adjust the ignition timing but I'd like to get some advice from you all first because my distributor does not have a vacuum advance port and the magnet below the rotor is bolted and fixed. I tried googling for some instructions but I can't find any with regards to adjusting a non-vacuum distributor with bolted pick up coil.

Also, can anyone explain how a spark knock or pinging should sound if my ignition timing to far too advanced?

Thanks a lot in advance and more power to us all..

Nick

Suzuki Turbo 660 WHAT?? Suzuki does not market a vehicle named "Turbo 660" so you need to either find the correct name for the vehicle, or, if you know, tell us what it is.

Thanks for responding

I apologize for the confusion. Its a Suzuki Every Van with Turbo 660 engine. My concern is my distributor because it does not have a vacuum advance port and the pick up coil is screwed tight and not movable like other distributors with mechanical advance springs and weights. I would like to know how to set the ignition timing correctly on this type of distributor.. I tried looking for information on the web but I can't find any.. I can only find instructions on how to set the timing for distributors with vacuum advance and mechanical advance that advances when rpm rises...:(

Many EFI systems handle the ignition timing advance in the ECU - the distributor, if there is one, simply provides a "base" timing reference which will tell the ECU how fast the engine is turning and where the engine is in the physical rotation and the ECU then looks up the timing in a preprogrammed advance table.

Setting the timing with such a system is typically done by rotating the distributor after "fixing" the advance, either by inserting a jumper or using the diagnostic tool - you will need to find the instructions for your particular engine.

On a different note - there is no need to adjust the timing unless the engine has been disassembled or tampered with.

I do not have an ignition timing module. My timing seems to be dependent on the distributor position. My car is EFI but it seems to have a mechanical ignition system. But unlike other distributors, mine does not have a vacuum advance nor the mechanical weights and springs inside the distributor that adjusts the timing when you rpm rises.

I tried to set my ignition timing by ear and it runs fine now. But I'm not sure if its too much advanced or just about right. Can anybody tell me what the signs of having too much advanced ignition timing are aside from pinging or knocking?

I do not hear a knock even if I turn it all the way to the advanced rotation. Or maybe I just do not know what knocking sounds like because I can't tell if its a knock or just my valve ticking; my valves tick a little loud. My car starts easily and my idle speed is stable at 1000 rpm. I'm just a little worried.

By the way, I went to an auto repair shop couple days ago and the mechanics did not seem to know what they were doing. After they adjusted my timing, my car run bad and hesitates when accelerating when coming from a full stop. I don't want to pay someone to fix my car who does not know how to fix it. That's why I decided to just fix it on my own. Again. thanks for your response.

Agree, and I am un-sure of a Suzuki EFI having a distributor?? or am I wrong on that one?? :confused:

Suzuki has EFI engines both with & without distributors - on the earlier EFI vehicles, only the fuel injection was controlled by the computer, the ignition was handled by a distributor with both centrifugal & vacuum advance, later production moved the timing advance to the ECU (which is what badman is describing) and the distributor was used only for base timing and to direct the spark to the correct cylinder, from there they moved to distributorless ignition, first with "wasted spark", and in the mid 90's they switched to individual coils, one per cylinder.

Thank you. I was only aware of the DI/EFI and standard ignition with carb systems on Suzuki. I did not know about EFI with standard ignition. So thanks again for clarifying that. The Alto was a 660 cc with turbo..yes??

In the states DI/EFI systems took over the market starting with general motors in the early to mid 80's. All the other makers followed. By the late 80's distributors were all but gone.
