It's not your fault...

There is no LV support for old NA and JDM cars I have mentioned.

I use to use Learningview which is very convenient, but now I bought a new EDM 2011 STi, and learningview cannot read this ECU. Somebody working on that currently ?

Merchgod,

I have been having some issues with my tune and my tuner has given me a couple of things to look at as far as possiblities as to why I keep seeing FLKC after about 3 to 4 hundred miles on the tune. So my question to you is Do my A/F's look off? and why does thearning View show 0.00 FLKC but my logs are showing some? My tuner belives that I am gettin an after MAF pre turbo leak.

I will dire some more and post more logs and another Learning View snap shot after 2 hundred miles or so.
Thanks!

Your AFR's are a tad off in the 50+ range, but since its a negative number, that means that your original maf scaling is causing the car to run a little rich, so the ecu is leaning it out. Try to find the rich spot and correct it and it wont lean out so much over time. How much flkc are you seeing in your logs?

After the reset none while in boost/OL. But when in closed loop below 1.0 load and below 2500 RPM I see anywhere from -.5 to -1.5. Strange thing is that after a couple hundred mile I will begin to see FLKC in OL between 4800-6800 RPM and will see anywhere from a -.5 to -1.05.

Well the low load/low rpm flkc is pretty common. Our cars dont like WOT in upper gears at low rpm. The high rpm flkc could be from what i stated in the previous post, your car is leaning out over time due to richness caused by imporper maf scaling values. I like to keep the 50+ section learning within +/- 1.0. +/- .5 is possible with enough maf work.

So do you reccomend re-scaling the MAF? WHat are the best values to see for the MAF all positive?

before trying to tune the MAF, I would make sure it is not leaking aka pressure test the system for leaks.

test pre turbo only or pre and post turbo?

Agreed, if you have a leak you will be chasing your tail trying to fix it via your maf scaling.

I am going to do a pressure test this weekend. I just have to go to Home Depot and get a PVC cap

Will LV work with 2011 WRX yet?

Doesn't work with my 2010 STI, so I'd guess not.

Hopefully Merchgod gets to release the update after the holidays. Good reason not to visit (some) favorite relatives. :-p

I've started working on it again here and there. I don't really have an ETA at this point, though.
