Drat. I'm still waiting for a chance to get both sides of my frame on the wagon welded up and aligned. Was a little rough on it inside the roundabout exits in my area. Weak factory welds gave way...

The hard current ceiling is coil protection, not coil optimization.
All one would have to do is to run the v+ supply (or ground) to the coils go through the control box first, so it can be...
:scare:
All this dwell talk can get intimidating. I was wondering....why not adopt the HEI method of dwell control? Set the ignition transistor to shut off @10A peak coil current, using a shunt...
On second thought, it looks like this probably would not be adaptable for a 13.5V system. You would have to run 18.5V to compensate for the voltage drop, and would need 10-15A diodes to get enough...
I'll refer you to page 20, post #288. But this one should be of primary interest to you guys.

Note the stacking of the diodes. 5 diodes @1v voltage drop each = 5V signal. The very...
Hmm. Perhaps it was time for the 30yr old logic pulser to die. One too many abuses over time. Probably kickback voltage along the ground path. I wish I had more time these days. Don't know how...
Looks like base dwell @ 14v ranges from 3.10 mS to 2.41@8000rpm.
Started testing my coils (12559693) to find the best dwell time. Ran into a snag. My radio shack logic pulser got killed triggering the coils. It is rated for 200mA max, and was overloaded by the...
I guess it is time for a project summary, then.
For those who weren't with us when it started, one merely needs to click the "Arduino based coil per cylinder controller for LT1s" link at the...
Do you suspect you are running into a lean-cruise vs cam situation? It would make it harder to jump the gap during a lean condition, for sure. Seen it with other vehicles that had vacuum leaks from...
The dollar bill is for anyone who can touch it ........while you are accelerating. "Go ahead, you touch it, you keep it." VAWMMMP! "Whasamatter? Can't touch it?" VAWMMP! "Stop hitting...
Don't forget to tape a $1 bill to the dash.
These are on sale at speedway motors. Tall, aluminum powdercoated black centerbolt valve covers by holley. ...
Very cool. I just am not sure what SOTP means. All this without the aid of an oscilloscope? Impressive.
I always did wonder if tall valve covers could fit in a vette or not. I bet those shaft...
I cannot remember if the VW tdi has a throttle body or not. I have been known to run a GDI engine without the intake manifold to heat and hammer the carbon off the valves after I hit it with a...
Here's the fun easy way to clean a TDI intake manifold. You will need an air compressor and a propane torch.

Introducing 0W-0 motor oil! It's less fattening and better tasting! Guaranteed to shorten the life of any motor!
Just kidding. I have seen my fair share of crazy mods to get around dropping the...
How did the test drive go for you? Still stumbling?
Well, with the 1x cam output, one could mount or buy a 24x crank reluctor while using a 0411 pcm. As years go by, and 2007-up pcms get hacked, one will probably want to switch to the 58x (60-2)...
Oh, well....I had figured it would have worked in sequential mode, but since the tolerance was never expected of the unit, I agree it is a bust. Rats....foiled again!
Well, I don't know enough about programming the 0411 pcm to know if it won't work. Retroprogramming, if you will. I figure somewhere in the memory, the math for crank velocity can be accessed from...
It requires 1.5 seconds of cranking without a cam signal to set a code p0342 or p0343. If it syncs within this time......no code will be set. Codes can be disabled in the pcm with a proper flash...
Hey spfautsch,
I noticed a youtube post where a guy did an EFI connection conversion, but had problems above 5000rpm with the crank sensor. His pcm read a much lower RPM when he hit 5200 rpm. So...
I finally am a little unfettered, for now. I have these on order for the coil outputs. I have a fondness for BNC connectors and shielded cables that has developed over the years, due to their...
Looks like I won't get much done this week. Parents-in-law dropped off their completely untrained and brainless springer spaniel to watch for a week. This obsessive-compulsive water drinking maniac...
