titan uranus Posted April 28, 2008 Share Posted April 28, 2008 82 zx turbo. Stock cam, t3/t4 turbo. Big injectors(unsure of the size) We are getting good A/F and it idles fine. To me it seems like the timing is not advancing when you rev it up. once it gets above 2k-3k it starts to act like it has antilag, lots of fire and poping out the exhaust and 15lbs in neutral. My guess is that the timing isnt advancing. Its running haltech e8. been struggling with this issue for a while now. it has a vaccum advance distributor on it. Im new to this whole tunning thing, im not the one tunning it, we have to really good tuners trying to figure this thing out. Ford 36-1 trigger wheel and sensor. Timing seems fine and fuel is good other than it being locked at 15 degrees. Does it need a different distributor or somthing weird with the haltech? if anyone has any ideas or a base map any ideas or thoughts are greatly appreciated, willing to try anything at this point.

83ZXER Posted April 28, 2008 Share Posted April 28, 2008 what kind of ignition are you runing? (msd, ect...) and why do you have a vacuum advance, you must have an N/A dizzy Quote Link to comment Share on other sites More sharing options...

83ZXER Posted April 28, 2008 Share Posted April 28, 2008 is ther a reason why you are using a distributor at all? if you have a crank trigger+ignition system, you don't need a distributor at all. Quote Link to comment Share on other sites More sharing options...

If you must run a dizzy, then you should be able to make the n/a one work - lose the vacuum advance and lock down the mechanical advance. You should be controlling the timing exclusively with the Haltec. What does your advance table have in it? Quote Link to comment Share on other sites More sharing options...

But there's no need to use a dizzy with the crank trigger. program your Haltec to get trigger signal and have your ignition system distribute spark.

If he doesn't have a direct ignition setup, then he'll still need something to hook the spark plug wires up to... Quote Link to comment Share on other sites More sharing options...
