what possible reasons would there be for not seeing a RPM signal. I know there is a rpm signal going through the wire because i can see it on the tach. I know that the solder connection is good as well because i checked it.

I am running fuel only. 415cc injectors.
What gives, I have emptied a 1/4 tank of gas and still no luck. Still no RPM signal. Could there be something wrong with the MS board and how would i test it?
Once I saw a correct RPM signal when i was playing with settings, then it went away. I could not get it back. I am using 024s9 firmware.

A few things, dont know if it will help or not though..For your afterstart enrichment, the numbers should be over 100%, meaning 100% adds NO fuel. I think my settings for that start at like 160%, then work down to 100% from there. So under 100% will cut fuel, and over 100% adds fuel.. For your cranking settings, the pulsewidth temps value should be set to coolant, not MAT.
Try those few things and see what happens. You should see a RPM in your display, and also a pulse width on the gauge in milliseconds while cranking. Is the engine at least trying to fire? It should do something at least..even if the fuel is not set right even. You sure your getting a spark?

Are you sure.....my afterstart settings are in the 30% range. Cranking is in ms from 12ms down to 5ms. the warmup is in 100% and up. I have the 022i6 code.
Going back to the RPM issue....are you running off the crank signal or cam or tach? Take a volt reading from the bottom of R10 (Resistor is removed, jumper is now in bottom of R10 per the board mods) when cranking......should be in the range of 2v and moving around.
Make sure your board mods are correct. Make sure your setting are perfectly like the setting need to be in Sourceforge.
DO NOT try to measure the resistance of a resistor while it is connected to the board. You can damage other components.

I don't see a pulse width while cranking, only it when the fuel pump primes. Also, while priming I see a tach signal of 2 rpms
I will check that resistance.
I wonder if there could be a ground problem because very often I would get this error message: "Voltage too low for reliable flash burning" when ever I send to ecu. I have a 14 gauge good ground wire going to pin 19 and that is joined to 7,8,9,10. Is that okay or should i use two ground wires?
When soldering the connector, the whole top row is ground right? so i could solder together as many on the top row as I wanted?

Check voltage NOT resistance. IF your getting that error while trying to reflach the ECU then it sounds like you have a building problem.
When you built the MS did you use the Stimulator to test it? If not i suggest you remove the board mods, return the unti to stock rpm input and test the MS with a stimulator to determine which circuits are faulted.

verify you have a good 12v source and ground to the MS and contact rodney so he can warrenty the unit. a low voltage error is most likely going to be a problem with the MS if you have a good 12v source and ground.
You can also check the output of the 5v regulator to verify good voltage as well.

It runs!!!
Okay, so i figured out the problem with the tach signal. I turns out this MS neeed to be wired to the crank sensor. I was sent the wrong diagram from rodney. That fixed it, the car started up and ran but was pouring fuel out of the exhaust (I have a dump tube) so i turned it off. My req fuel is 8.0 and my VE map looks like ner947's.
btw the right diagram for the www.rs-autosport.com MS neon configured units is at:
