Interesting, I haven't been tuning a lot lately due to building a house (and a really really nice garage). But I may have a new STI on order by the winter.

Interesting about the target boost value. That being said, I don't think Bill has ever written anything like that in his ECU analysis area in RR. Although I do learn new things everyday. FWIW everytime I have seen FLKC go up, it was evidence by an increase in knock sum. Also, if you raise the load value for IAM evaluation, you don't stop the ECU from reacting, you just stop it from using IAM as a way to react, it can still use FBKC or FLKC.

Then change the IAM load parameters, can't remember what it is called off hand, but it is the part that says what loads the ECU can make changes to the IAM. On my old LGT with my clutch I had to have it not change IAM unless the load was above about 2.0 or so.

Doesn't affect me right now, but thanks for doing this research. Helps the community a lot, can save a lot of people a lot of troubleshooting time.

I am interested in your theories, cause that launch makes no sense, unless lots of cars there get launches in that ball-park.

I was thinking about this the other day. The 9 second Subarus are pulling 1.4-1.6 60 foot times, the 11 sec ones are doing mostly 1.7-1.8 with the odd 1.6. I really don't think you did a 1.384 60 foot time.

You got a 1.38 60 foot time? I am working on a tune right now for an AutoX guy (using ATR) and we are making the fans come on at a lower temp, I don't think we have that with OS for the 05 LGT, but it is an interesting idea.

yea, high IAT are a problem, had it in my car too, 186F IAT and when I airboy'd the run I was at 250 whp, even though 20 mins earlier I was at 300+ (this was 3 years ago). You need to tune for high IAT. Look at your target boost, real low. You likely have target boost reducing based off of IAT.

True statements, but may I add the required 4th gear high load scenario. None of these will spool anywhere close to that in 2nd gear, which is used a whole lot for many DDs in the city.

That is not normal. Properly tuned that will not happen. (unless you had a bad tank of gas or something)

Knock sum results in one of 4 things: -nothing -FBKC (usually seen when load is quickly changing) -FLKC (usually seen when load is stable) -IAM change (usually seen after FLKC has already retarded things a bit)
