Currently trying to tune my M20 turbo, having an issue with it going lean (18:1) under load ect. Accel enrich and ego control are off.
The wastegate also opens around 107KPA. The spring is meant to be a 7PSI, haven't bench tested it though. Boost control was turned off during the log. Not sure if thats related or a separate issue.
I've never tuned before so I'm not sure how to use the log to work out the issue. Could someone have a look for me please? Log was about 30mph max 1st/2nd gear.
M20B25 9.7:1
HX35 16cm
44mm ebay gate
630cc injectors
wasted spark
megasquirt 2
timing verified with light
