Megasquirt 1 No spark after "Joesparkmod"
Hi guys.
I have a 1990 Jap Roadster, megasquirt 1 v2.2, LC-1 wideband sensor, T3/T4 turbo, and BMW TPS. I had the car running on the old spark mod, but only with the spark inverted = yes. This caused the ignitor module to get too hot to touch and burn out, so I did the Joe spark mod and fit a new ignitor module, now I have no spark. I've ordered another ignitor module just in case, and I recently fitted a new coil pack. I've trawled through the other posts in this section and found one that related to my problem, but his was sorted with swapping Spark inverted = No. Can anyone shine a light on this for me? Cheers |
Did you change to inverted=yes after the mod?
|
Yeah I did make sure inverted=yes
|
So it's worked opposite of how everyone else's has worked?
We usually go from No to Yes with this mod, but you're saying you've gone from Yes to Yes after a mod? Definitely something fishy. Post pictures of the two sides of the board. |
Yep, would only work with inverted=yes when I had done the old mod, and now with the improved mod it wont spark.
I'll get a picture and upload it after work when I get home. I had the help of an Mx5Nutz forum member (MrSlow) when I started out with the megasquirt. |
Just thought I'd post this while I remember to -
I have the 2N3904' wired as Earth to Q9 Base to "-" side of D17 Collector to 1/4w resistor connected to pre R23 (1/4w resistor then goes to X12) The other is wired the same but on Q11, D19 and R27 (1/4w resistor then goes to X11) |

Okay, sorry for the delay in posting the pics. I've had no internet over the weekend.
Here are the pics of the top and bottom of the board. https://www.miataturbo.net/attachmen...ine=1379320918 https://www.miataturbo.net/attachmen...ine=1379320918 |
Went back to the old spark mod and I have spark again with inverted = No, it just wont catch and idle (had it running as Inverted = yes previously).
So confused......not anymore, it's a timing/trigger angle issue now. |
