M3Ali · 02-20-2015, 02:09 AM

Having an issue where when I wot in map1, car goes changes into map 4. And the SES light comes on and turns off. When I do the same in map4 car pulls fine. Had my sparks changed about 5K miles ago. Any ideas?

Coils, log and check codes

How many times does the SES flash? Any logs capturing the event? That will make it much easier to diagnose and I would do that before buying coils. If it is doing it routinely in Map1, just log it.

Remember
1 SES flash switch to Map 4 = Boost > boost failsafe which is default at 18psi
2 SES flash switch to Map 4 = Run lean safety (AFR >14:1 over 4k for more than 1second)
3 SES flash switch to Map 4 = High fuel pressure drops below 800 psi

It flashes once, but I have the gas gauge to boost psi and it never passed 15psi. And yea, just map 1

You might have Menu 10, 11, and/or 12 not set correctly (or high enough).... specifically the open fuel loop... just a thought... but taking a log and posting it up would allow people to better help you.

It's never done this before. I've never messed with those settings. I've never logged, once I figure it out. Will post em
