My name has appeared in a few magazines but not as "Delcoman"
No the Delcoman your thinking of came from SA.
 
Thanks for your encouragement.

How did you overcome the distributors vr signals?

What sort of problems are you having with your distributor vr signals?  What's your application?  What are you trying to achieve?

Hey thanks for replying, I haven't actually started a conversion yet, I have started looking at a hondata conversion but the biggest issue is the Toyota distributor output is not compatible with the Honda ECU, everyone suggests to replace the distributor with a Honda one meaning that my stock toyota ECU will no longer be plug n play.(I havnt researched enough yet to see what the Honda ECU is expecting to see if I could make a circuit to allow it to work, my guess the teeth count is the show stopper though)

I notice that in your first post you mentioned that you had to overcome a distributor vr issue? I'm not familiar with GM Delco ECU yet, can you program a Delco to be able to understand the Toyota distributor? Or did you have to fit an inline "conditioner" to allow the delco to understand Toyotas distributor outputs?

Cheers.

Sorry I have not posted this earlier.  Have been very busy driving my nephew from England around to see what Australia looks like.
 
Yes I agree keeping it plug and play was my first priority also, unfortunately taking this approach makes it far more difficult to overcome new modifications that won’t suit both ecus.   The biggest problem with the Toyota 3SGTE distributor is the common ground VR signals.  I have read where some people have modified the distributor wiring and separated the signals buy removing the common ground.  I did not want  to remove my distributer so decided on modifying a module I had previously made to run a Lexus 1UZ engine on a Delco ecu which ran flawlessly for years.
 
The 1UZ also used three VR signals, two for the left and right cams and one for the crank.  Just had to modify this module to suit a four cylinder engine.  With this accomplished I tested it with the Delco in my AW11.  Engine started and just had to change the reference spark angle within the Delco program to get the timing back to 10 degrees BTDC with link in.  Although the engine would start and run well in the lower RPMs up high 6000, 7000 the engine would miss due to false triggering caused by the common ground VR signals form the standard distributor.  I had to find a different approach.
 
Came across this, Dual VR Conditioner Board V2.1  http://jbperf.com/dual_VR/v2_1.html

This certainly looked like it would work with the standard 3SGTE distributer but after several months trying to get this to work, I realised that this little device was far too sensitive to work with cross talk VR signals caused by the common ground wiring in the distributer.
 
New approach.  Why try and invent the wheel.  Toyota had overcome this problem, so decided to see what filter network was used in the standard Toyota ecu.  After retracing the VR input circuit and finding a very elaborate filtering network which uses separate paths for each VR signal it was obvious that I had to use the same circuitry for the Delco ecu.  Engine now runs cleanly to 8000 rpm.

Did the 3SGE motors ever use the Toyota VAST ignition systems that were applied to 4AGE's of the late 80's?
The VAST igniter dealt with both driving the coil and filtering the VR signals from the distributor. It filtered the tach signal into a simple 12V square wave signal which was sent to ECU. The VAST ignitor runs a standard 10 degrees of timing unless provided a 5V square wave signal on the IGT wire, which then gives it the advance amounts.

The VAST unit is so simple, you can run the car with the ECU removed and just spraying starter spray in the intake :)
 

 

I am sure many distributors could be used/modified to run the Delco ecu but as soon as you do it no longer becomes PNP
 
This 4AGE distributor (TVIS)     http://embeddeddesign.co.nz/install-guides/toyota/16v-4age/
has only 2 VR Sensors.  Whereas  the 3SGTE uses three.

Good to know my Delco conversion will be PNP with the 3SGE
 
I know the path I am taking is a hard one but the results I am getting with the Delco ecu is very pleasing and besides that I love a challenge.
