Random trigger errors at full tilt

[88a5tq]

I have been seeing this very randomly and rarely in my logs during WOT pulls. The trigger indicator boxes go red above 5500 rpm and stay read until rpms drop more off throttle or I shift and pull again. It's sort of rare and very intermittently.

I have new bellhousing sensors but they are eBay ones on the cheaper end. As far as I know the machinist DID NOT balance the new rods lol. He says "oh it's so minute it doesn't matter and also carbon buildup throws it off eventually anyway" and this is the guy who's crew destroyed my oil check valve and left me no pressure reading after the engine refresh!

Anyone think it's the poopy sensors?
Thanks for reading

Don't worry I've already made adjustments to my fueling. This is the hottest the cars been out in so far. Doing some ironing



It's the primary trigger.

If it's any consolation, I have the same thing in my AEB when flooring it.

Thanks Chris. We can both hold out for advice now lol. It has mostly stopped unless I'm not logging when it happens. I'm not sure the cause yet..

Ign noise can cause this. Make sure your shielding on the trigger wires is good and away from the plug wires. Also run resistor plugs if you are not. Most factory are but the NGK 8 and 9 heat range plugs are not.

Oh dang good point! I'll see what my plugs are thanks Jim

I found some causes of my trigger errors. My DIY PnP adapter.
The VR signal wire and cylinder 1 ignition trigger had a bad solder. Fixed.

However, still have a secondary trigger error at times when dropping below 600rpm or so.

Well dang. I'll have to see if I have any similar issues... However, I have an inspection coming up too lol
