LOL glad you guys took my idea and ran with it.

LOL glad you guys took my idea and ran with it.
So all the coding is way over my head, and I am sorry I didn't contribute much past opening up some cases, but I do have a decent running engine that I can test on, and it sees high RPM all the time....
Hey guys, I am back after a super long time, things have been super busy, and it looks like I have some reading to do!
The leading edges of the low res circle are 45 degs from each other. We are assuming that the leading edges trigger a counter for the high res signal that is stopped by the trailing edge of the low...
I've been too busy trying to get my car back together to look at the delteq too much. Hopefully this week I can spend some time with it. Your theory sounds pretty good since it is easy to just...
I dont think we'll use an lt1 coil, i think the idea was to use the ls1 coil
Here's the coil schematic. Looks like it just needs a 5v signal

I forgot that you had found the transistor already...
More relavent reading. LT1 equipped boats used the Northstar ignition system

Found this pic of the LTCC that uses the LS coils

So does that mean we need to figure out what is on that eprom? I would almost rather use the LT1 ignition module and then use LS coils. I believe that is what your original plan was, right?
Soic chip says HCF4050 31A317
I took the delteq apart and heres some pictures

VF, I know those hall effect sensors might be more durable than the optical sensor, but Im not sure. It was hard to find one that had high enough frequency. I think a well sealed opti with no HV...
Summit and Jegs do have shortblocks and longblocks for sale
Awesome, thanks Tom, I'll let you know what I find out
I will definitely check this out, thanks for the continued work on $EE
It would be easy to do the 0411 PCM conversion, but I guess I am being cheap and trying to keep the LT1 PCM
More rambling, but could you basically make a trigger wheel with 360 slots and one with 8 slots for the LS sensors to pick up? would whatever crank sensor is used in the LS engines work? Im gonna...
So my Opti officially died on me today, I did more research and there are some guys that have attempted to take normal hall effect signals like 58X and convert to the signals to the square wave that...
Tom once I get the Delteq I will pull it apart and see if I can make a schematic so we can compare to Vilefly's work. I wonder if a better cooled and sealed Delteq unit would be the ticket. I would...
if you want, the diagram would be great as well
I know Steveos $EE XDF has that flag, but unfortunately that only works for 94-95
50 degrees?? that seems insane. we really need to see what is inside the converter. Do you at least have a wiring diagram or remember how the converter is hooked up into the system?
http://www.goldsswagon.com/PCMFlash/HowtofixthePCMFlashMemory.htm Have you seen this before?
getting back on topic, assuming we decode the opti signals successfully, what other true/false...
