Problems/Symptoms: on the stim test board, everything except the RPMs worked as they should. says "Not RPM synced" in the boxes below the gauges on tunerstudio.
in the truck, pretty much the same thing on tunerstudio. when I try and start it, it just cranks. RPMs don't move. no puslewidth. no power at the injector wires. we do have spark. but no start. doesn't even attempt to.
alright, assembled my ms 2 ecu kit w/ PCB3.0 as instructed from the manual (after doing a lot of reading, this might have been from the outdate manual)
then I followed the "required steps" from this link - https://www.diyautotune.com/support/tec ... your-22re/
a few things from this site were wrong/very misleading (afm delete wiring) but where I messed up I think was in this step here,
now how I have it ran is one wire from "5v" with a 22.3 ohm (just checked the wire now and found out its the wrong resistor 22.3 and not the 200-250 ohms) runs to the "IGN" holeRequired changes to Megasquirt:
The stock Toyota ECU uses a system called VAST to control ignition. This system allows the ECU to do complete timing control. It also means that there is a “black box” (igniter) between the distributor and the coil. As such, we have to make some very minor changes to the megasquirt system. I’m not going to go into the theory of WHY we need to make these changes (such as expected signal amplitude), but suffice to say that these changes need to be done, otherwise we can’t integrate with VAST.
Required changes:
For the ignition input:
Install a 1k resistor between the right side (non-band) end of D1 and the left leg (banded end) of D9. This is for a 12V pull-up. Note: the “side” is critical here.
For the ignition output on LED14/Pin36:
Bring the ignition output from LED 14 (D14) to a pin on the DB37 connector.
Use a small piece of wire from LED D14’s leg that’s closest to the DB9, over to the hole labeled IGN at the opposing side of the board. This results in the ignition signal OUTPUT on pin 36.
A 5v pull up is required for this connection. Use a 250 ohm (200-250 ohm will work) resistor from either one of the two 5v sources on the board (they’re labeled +5v). Just above the proto area. Run the resistor into one of these +5v holes to the wire itself – or directly to the hole labeled IGN.
and the LED d14 wire with no resistor also runs to that "IGN" hole.
is that correct? should they both go into the "IGN" hole?
