ECMlink Ignition breakup? WOT

[bryanzomg]

Mods are up to date
-Base Fuel Pressure 42.5 PSI
-e85
-NEW BR7es gapped @.019
Injectors cleaned and flow tested last month (new seals installed)
I did a BLT up to 30psi no leaks. I seem to have ignition breakup at around 6k rpm. I even lowered boost down to 19psi and still did the same thing. I have ACCELS thundersport plug wires I installed new last July but they did sit with the car outside over winter, could they have gone bad already? I can't figure out if it's tune related, I ran the same tune last year and pulled cleanly to 8k RPM labeled "clean pull 2022" and I also have a current log labeled "2023 pull" where I start breaking up around 6k and up. I am at a loss if someone can take a look at the logs and have any suggestions?

It's too rich for e85. Both pulls are, although the newer one is quite a bit more so. I wouldn't THINK that it's rich enough to cause a misfire, but, it's possible. I would also pull and inspect/clean the plugs if you haven't already.

The newest tune is locked in open loop too, if you didn't know.

I figured it shows richer since it’s not sparking the fuel. Should I make adjustment through global?

I ran a set of the 10mm thunderbolt wires for a short time and found my car was having random misfire issues. I swapped them for the NGK wires and it went away. Something to try if you have a regular set laying around.

I second swapping the plug wires if you have extras laying around. And no I wouldn’t change it through global, I would change the target afr from 11.5 to 12.1 and then go from there, tuning the sd map as needed

You could always add split loom to each wire and fill the caps with dielectric grease in order to determine if it's leakage and arcing you're dealing with.

add grease where. I added it on the porcelain part of these fresh plugs

I was under the impression not to get it any on the inlet tip

Where the plug boots come into contact with the valve cover. If you have minor cracks in the rubber, the grease can help to fill it and prevent arcing. Basically, I'm shooting out ideas to completely isolate the wires from anything else metal that they come into contact with.

Can u also apply some to the coil pack on the outside where the rubber on boot sits on coil pack

 

[curt-s]

You can apply some there to help keep out the elements but you should be able to see a crack in the plastic on the coil pack. At least, a lot better than rubber, but go for it. Dielectric does not hinder metal-to-metal contact, such as the plug wire ends inserted into the coil pack. It's actually recommended in many cases.

Hey guys I ended up pulling plugs and gapping them down to about .017
I then proceeded to swap in NGK plug wires and I wire loomed them.
She now pulls up to 8k clean thanks all
