Well I got the Wideband/Boost Failsafe gauge installed today... I did not do the FP yet just to keep the results the same even though the weather has warmed up quite a bit(45* to 65*)

Well anyway on to the interesting info that everybody wants to hear.. The final AFR seems to float at 10.7-10.8 which is exactly where it is set to BUT on the other hand it has a massive dip to about 9.9-10.0 that has to be fixed! I am trying to figure out how to use the software to get datalogs and all that good fun stuff!

I will keep updating as I figure this out and smooth out the AFR!

Also to Ron. I had to downloaded the needed version of Microsoft.net and everything seem to go smoothly. Still trying to understand how the AEM program works but other then that it was a pretty straight forward install as far as install, open, update, restart, and have fun!

For some reason the .net framework just wont install correctly on my laptop.

I wouldnt worry about using the software for logging....its much easier to look at the data when its just in the romraider log....otherwise you're trying to match up rpm and MAFv from Romraider to the AEM log.

Im quite surprised at that AFR, with the IDC only at 96-97% at redline i would have exected the afr's to be well above 11 up there. Even 07+ STi's are at 100% IDC up there at 10.5-10.8 AFr's and they have the bigger 565cc injectors.

Heres a stage2 07

Just a little update on this... I've been fighting fuel trims and believe the front 02 is bad so I'm replacing that tomm! Hopefully will only take a few days to dial everything in and then make sure OL is good to go.

So far so good! Installed the new front o2 sensor and cleaned the MAF. WB now reads just about right and fuel trims are close from what I can tell in the short period of driving I've done(within 5%).

I will have some new data logs tonight of the new OL scaling to see how that looks. Hopefully I am close if not right on to match the OL table within .1-.2 across the board. I am waiting on my MBC to show up and then to install the Wally 255 so she can be happy for a while!!

You do realize that you don't have to have the fuel map match the exact afr your running. It isn't intended from Subaru to be exact match, it's just easier for people to read AFR instead of pulse width. If making it match throws off your maf scaling so that it isn't linear, that isn't really a good thing. Just my .02.

I scaled it within .2(actual AFR being .2 richer) and the MAF still looks really good. It is just a personal preference of mine to have it match... Now to install the MBC, Wally 255 and all my wrap/turbo blanket/Heatshield!

I will post an updated log/graph once everything is in...
