Hi, this is my first time posting here as I just finally got my car together and first time with speed density. A little background: I started tuning with SAFC2 and buying EPROM chips from dsmchips back in the day. I got out of the dsm world for about 3 years and got back in after coming across a stock 97 GST for a great price. Mods are as follows:
3inch downpipe, megan catback
MHI s16g stock wastegate
rebuilt 7 bolt (stock)
injen CAI
ebay FMIC short route
ecmlink V3
LC2 WB simulating narrowband no gauge
850cc injectors
walbro190 w/ stock regulator
BSE kit installed
ngk bpres6 gapped .28
stock base fuel pressure
93 octane fuel
I followed the guide to get started. I adjusted the airflowperevsd to .25 +/- .1 by tracking corresponding cell in VE table. Adjusted combinedFT to within 0 +/- 3 and STFT hovering around +/- 4 from 0. from there I drove around for about 40 mins and logging data. I then copied the bold numbers to the ecu and saved. I've done a couple of 3rd gear pulls and it seems like it takes about 1000 rpms to switch over to open loop, but during the transition, boost is already around 6-7 psi, afr at around 13.x, some knock building and disappearing once it switches to open loop. during the transition, afr begins to settle around 12.4ish attributing this to the evo8 map iv'e downloaded as base from ecmlink. I am posting some logs to see what ya'll think, what am I missing, mistakes im doing, etc. I am a newbie at ecmlink and I am willing to learn, I just would like some guidance so I don't mess this newly rebuilt engine. I've been trying to add to the corresponding VE table to richen up the afr but no change. Im thinking i'm adjusting the wrong table. Appreciate the help.
first two pulls are 3rd gear pulls, map sensor indicating 21 psi boost. last log is a cruise log.
