I had a guy build me a diypnp ecu. Everything is communicating with the ecu except that im getting no spark. When I tested the coils in Turner Studio thier was nothing until I got to coil D. Testing coil D wasn't producing any spark but it was turning the cooling fan on. Does that mean that thier is a wiring issue in the ecu itself? Going to look at it more when I get off work but any help to how the board should be wired for the factory coil pack would be very appreciated!

Please post your MSQ.

here is my tune as of now

For testing purposes, unplug the coils and change the spark output to Going Low. DO NOT PLUG THE COILS BACK IN UNTIL YOU'VE CHANGED IT BACK TO GOING HIGH. Check if you have 5 volts on both spark outputs at that time.

Ok I will try that when I get to the car later today. What grounds the coil pack? I plan on tracing my grounds today and making sure tgey are in good shape.

next time have someone that knows what they are doing build you a diypnp.

you only have two coils, so i dunno why you are testing coil D.

sounds like you have the cooling fan on ALD which is why it turned on the fan when testing. I'm going to assuming he loaded regular ms2 firmware and not microsquirt firmware...

skippy008

Yea... I checked the pin-outs from a thread that I believe was the 91 miata no spark. It looks like all my pin-outs are in the correct spots from what thst thread shows. Could it be the firmware? I read somewhere where you might have to download the microsquirt firmware because it uses the correct pin-outs?

skippy008

Ok. What is the download actually called for the correct firmware? Thanks for the help!

its all the same firmware but theres a setting when you flash.

on the ingition settings page, what does it say the ignition output is set to? I cant see the msq here at work (or screen capture)

skippy008

See attached file for the screenshot of my ignition settings. Spark output is Going High.

firmware seems fine.

but youre setup for single coil; you have two. use wasted spark.

skippy008

Well changed the setting to wasted spark and still got nothing. Also unplugged the coils and changed it to going low and tested the volts and was getting 5v on both. So I figured maybe my coil pack was bad so replaced that with one out of LKQ and still nothing. The one from LKQ could be bad as well but, idk.

skippy008

Also plugged the stock ecu in and still got no spark. What could cause this? Im still getting a rmp signal but I did notice that at one point I wasn't getting a rpm signal. I will upload my composite log later tonight along with my msq.

skippy008

I have attached my composite log and my current msq.

if your stock ecu cant spark, the aftermarket one never will.

skippy008

thanks for the input guys. The ignitor was bad, put a new one the car and it fired right up. After I got the base timing for the car and got the idle to run smooth I tried a short little rev and it wants to loss rpms fast and sputter. I did put a vtps from bmw on it can its communicating with the dyipnp perfect. I will post my current MSQ file for you guys that want to help, fill free to look at it! any input will be very helpful.


Thanks

Here is my current tune.....

Matt Cramer

Can you also post a data log of the sputtering?
