LOL, alrighty. I'm getting a timing gun this week when I have time (hah)...school is almost over thankfully. Saturday will be the day the motor starts or craps out.

I still can't seem to get the timing straight...is it me or is it tough to use a timing gun and see where the marks are AND line them up with the pointer?



Or maybe I'm retarded.



I can get it to run for 10 seconds or so every now and then, with my foot at about 50% throttle. There is lots of smoke, white in color, and oil dripping out of my downpipe.

With the timing light connected to leading plug 1, it seems like it's flashing WAY too often. I can see the timing marks before they line up with the pointer, and after, that's how fast the timing light is flashing. Is this right? Or is this just a product of cranking where the RPM are not always constant?

Well right before I left to come back to school I got it to idle for 15 second intervals. I think the engine gets flooded, because it takes some time before it will start again. It was idling around 1500rpm.



The problem was, the timing of course. I followed DigitalSynthesis's instructions and lined up the -20atdc marker on my pulley and locked the timing at 10 degrees. She purred like a kitten.



Now to figure out the pesky flooding problem...oh, and I even made 2 psi of boost! I was trying to save it from dying...

Maybe a datalog would help diagnose?



I'm not sure what would be needed in that log though...

if its too rich, lean it out. thats why you bought the ecu... data log might help you figure out where to lean it out (what bars), once you get the hang of it though you dont really need it too much

I'm just a n00b though, that's why I was asking, just to make sure I'm not missing anything. Wouldn't want to do something stupid now and damage something.

if the car sounds like a bridge, brap brap brap, its most likely rich and if it slowly goes up the rpm then down then up then down its lean. so make teh necessary adjustment to make it idle. also check the throttle plate opening to make sure there is a big enouf opening for it to idle. you might want to start big adjust the fuel and then turn it down and adjst the fuel. this should be easier for a noob. or you can just send me your car and i will gladly accept it as a present.

That brings up an interesting point .



Is there a science to adjusting the TB opening? In other words, where should the adjustment process START: the TB or adjusting the amount of fuel?

if you have no idea where the tb opening should be make it large so its open aroudn 1-2 mm and then try to make it idle high with that and work your way down slwoly adjust it smaller and if you see it not runign smoothly play with teh fuel and timing some untill it does, then go lower untill u get to idle aroudn 1k rpm assumign the port is something normal.
