5SFE Ignition Timing help please Options

[Projek_01]

So 2 weeks after I installed my 98spec 5S, i discovered that my timing is at 5degrees (obd scanner) vs 10degrees in the manual. I tried turning the distributor but it wouldn't budge much. Does this mean I did the timing belt wrong and installed the belt 1 tooth over? Thanks!

thats not how you check timing.

i scanned it with a old fashioned light and a OBDII reader. I am sure the OBD way works because they both say 5degrees.

thats now how you read base timing, search.

Not sure on what the cause of the problem is however I believe on the 96 and up 5sfe you can't turn the distributor to change the timing, the ECU controls it. On the 94-95 you can turn it, difference is on the 96 and up the distributor can only go in one way.

thanks for your reply! it is confirmed that my timing belt is on right so that means that i need to find a 94-95 distributor then. Would 5degrees vs 10degree base timing effect my fuel economy and or power? I am assuming the ECU would just make up the difference?

http://www.toyotacelicaonline.com/timing.htm check your timing CORRECTLY before wasting money. while you can't advance timing at all on your 96, the procedure to check it is the same as the 91.
