akeizm Posted April 29, 2005 Share Posted April 29, 2005 Hey all, I fired the Z up for the 1st time today for about 10 secs and I'm so damn happy! But I have a quick question. When setting up my timing using moby's newest map I could only get my timing to 35 - 38 btdc with the dizzy fully advanced. Would this cause too much of an issue? For basic engine specs look below. L28e converted to Turbo (n42 block with dished pistons, p90 head) New Bearings all round New gaskets all round New rings t04e/t3 hybrid turbo 440cc supra injectors walbro 255 fuel pump Optospark Ignition (damn thing saved me alot of money) Only run 98 Octane Unleaded Petrol (Thought I'd add it) But yea, is it bad to run the thing @ 35 - 38 btdc? Heh my car wants to live and not turn off. I turned the key into the off position but it kept running smooth hahahah but how can it if the relay that provides power is off. Anyway, thanks Marc.

mobythevan Posted April 29, 2005 Share Posted April 29, 2005 Phasing the distributor and rotor can be a little tricky, but if you are using an (edit 82-83) optical distributor it should be straight forward. Following the directions given with the MSnS code. One thing is to get you trigger angle to match when the tach signal triggers from the distributor. THe other is to make sure your rotor lines up close enough to the post on the cap for all timing (~5-40 degrees). Their recommendation is to get it centered on the post at about 20 degrees.

midnightzxt Posted April 29, 2005 Share Posted April 29, 2005 my trigger angle is like 50.. it'll be different for all cars. Quote Link to comment Share on other sites More sharing options...
Tony D Posted April 29, 2005 Share Posted April 29, 2005 Optical CAS 82-83 81 is, as you know, tirggered differently... Quote Link to comment Share on other sites More sharing options...
mobythevan Posted April 29, 2005 Share Posted April 29, 2005 That was a typo, I meant 82-83. my trigger angle is like 50.. it'll be different for all cars. It doesn't have to be different. Everyone that is using an 82-83 distributor can set their trigger angle the same (like 50) and then adjust the distributor until timing is correct and then we would all have the same setup.

akeizm Posted April 29, 2005 Author Share Posted April 29, 2005 I've got the car @ 50btdc but I can't find a tigger point, or even @ 40 for that matter. Is it possible to open up the dizzy and rotate the optical disk? I should have added its an 83 Dizzy heh. But the main question is, is it safe to run with the car set @ that timing?

mario_82_ZXT Posted April 30, 2005 Share Posted April 30, 2005 First, Congrats. You should have a trigger point almost anywhere you put it,since it fires realitively frequently. also, I found it best to set the timing using the fixed angle at about 10 BTDC (easiest to see) and matching it up by moving the distributor. Maybe I'm not answering your question cuz I don't really get it, Mario Quote Link to comment Share on other sites More sharing options...
midnightzxt Posted April 30, 2005 Share Posted April 30, 2005 i agree with mario.. there were three times that the led lit up for the trigger in the ecu.. i just picked the center one. have you checked the 12v wire to the ecu and the tach signal? etc?
