I have posted this on another sub forum but have not received any responses so thought I would try here.

2015 M2351 RWD Auto

JB4 Map2
Circuit Werks ***-less DP
Muffler Delete
VRSF HD Intercooler
BMS Intake
VRSF Charge Pipe

Do not have EWG cable
Stock plugs and coils

I was running map2 right after putting the on DP and the BMS Intake. I experienced some slight hesitation in part throttle cruise and did not reach boost targets. So, I tried adding e85. 2 gallons with 11 gallons of 91. The 91 is around 10% ethanol so I imagine it is about e23. Once I did this I still had the slight hesitation in part throttle cruise and did not hit boost target. I noticed the AFR looked a little leaner, trim was higher, and average ignition want to 2.7 vs 0 previously. Log ending in 0811 corresponds to this.

Then I did some searching and saw it recommended to change the user adjustment for FOL to 60. So, I did that. At this point it began to run a little rougher at part throttle cruise and kicked me to map 4 with safety code 2 which I believe is a lean condition. But, the trims looked better. I also noticed that the timing on IGN6 looks super wonky. Log ending in 0617 corresponds to this.

Can you take a look and let me know what you think?

Do you have a means to flash the car?
