Did you call up the magnets to see if the trigger magnets as well as the sync magnet is seen? If you put the sync magnet in backwards, it won't crank. If you put any of the magnets in backwards, have fun sourcing another pulley.

As Dee said, are you seeing all 3 magnets on the SDS? Have you checked the physical timing against the programmed timing and adjusted the magnet position?

If you have fuel and spark, and the spark is happening when it's supposed to, the only reason the car wouldn't run would be improper cam timing.

Did you put the sync magnet on the correct side of the #1 magnet? It's easy to put it on the wrong side, and then everything fires 180Â° opposite of what it should.

the cam timing is correct(spot on). when i turn the crank manually both trigger magnets are seen as well as the sync magnet. i also get a backfire through the exhaust after cranking.the magnets are in the correct position as far asi can tell. i have to try again this evening to see what's happening.

tried and tried with no luck. put the magnet position as far out as possible at 100 i think and the car gave a little 'umf' more so that's a little encouraging. i was told that by increasing the number u retard the spark. was also told that the car may be too rich and thus outing the spark and hence when i increased the number hence retarding the spark then it caught slight. i had the 500-1000 rpm number 60 from the sds supplied chart. was told by the same guy that he has starting numbers in the 30 something range and his car is a peugeot 1900gti turbo with 550 injectors. so he suggested that i clean the plugs and start my base fuel at 30 and go from there. what do u guys think.

What injectors are you using?

And definitely "no" to starting your rpm fuel at 30. That's waaay too lean for those 550s your friend is using.

i'm using 560cc from mitsubishi evo 5. i've tried everything else

Does the actual the ignition timing not match the programmed ignition timing? That is the only reason to mess with the magnet position.

Also, as Dee said, 30 is WAY too low for those 550's. Try starting more like 80.

I'm going to say this and if you chose not to listen, that's your choice. A MAGNET OR TWO IS IN BACKWARDS "POINT BLANK". The symptoms you've explained to us are symptoms of magnets that are installed wrong. Keyword "BACKFIRING" as the SDS doesn't create a backfire unless you've installed those magnets incorrectly.

i'll check again but i'm pretty sure i installed them correctly. blue side facing the sensor for the trigger magnets and blue side facing away for the sync. thanks for the input guys. i'll let u kno the outcome.

I'm very sure that installation of the magnet illustration from SDS got you all turned around. That illustration is actually the back of the pulley, but facing you for a better example. If you thought it was the front, you're in trouble.

no i got all that covered i knew it was the back of the pulley. got an email from race tech last night said i should start my fuel rpm around 50. i'll try that since they made the sds. was also told the rich mixure at 80 may be outing the spark and when i retarded the timing position to 100 and it caught life slightly that that would explain it since the spark was long after the gas was intoduced to the cylinder.

quetion to float_6969, did u experience any trouble installing ur sds?

Post by **float_6969** » Sun Apr 26, 2009 3:50 pm

Nope. I had never installed any kind of standalone before and it fired up first try for me. I've installed 4 more since then and they've all fired up first try as well.

ok thanks alot guys. the car has started and idled yesterday.found out 2 things.firstly the car was way too rich. 500 to1500 rpm is set at 38.second thing is the richness fouled the plugs so with new plugs it started in one.i'll keep u updated as i try to tune it to my goals of 400hp.

Post by **float_6969** » Mon May 04, 2009 2:54 am

Congrats as well! Thank god it wasn't incorrectly installed magnets or you could've kissed that pulley goodbye. Good luck with your goals and keep us posted.
