I just sent you back my analysis and revised mapping.

Soon my friend. Things are still under development PS I just sent some stuff back to you. Very interesting, I think we are on the right track.

Oh. I was just making sure that crystal knew he had an e-mail waiting for him that addressed everything he said plus added more info. I haven't flashed anything yet, etc. I'll be sure to post something - anything - as soon as I have anymore info on this.

I didn't get anything yet. Off to bed with me I'll check tomorrow morning.

Well you guys had better give me good info soon, or else. I'm just working up a bracket to keep my IWG closed, then I'll be pretty much ready for those magic map values to work into my new tune. Don't let me down. I know you won't. I'm counting on you guys. You can do it. Rah, rah, rah.

You should be receiving two emails. One in response and some fun things to check out and blow your mind (not in regards to the FMIC issue) and the other is something to take a look at just for comparison sakes into how I got my setup to run pretty much right at this point. I suppose you will be able to tell I sorta cheated the system into doing so, but hopefully what we are working with will do it right. Well hopefully is the key word.

You guys should get some solid conclusions by weeks end into what modifications we are trying to work and whether they will actually do anything or just stay mysterious in regards to what they were put there to do to begin with. Basically going through what all tables we are able to access and trying to pick through the logical ones that have random values which seem to really have no reason to be there in the first place unless they were designed with an intend to be run on more modified cars which they run elsewhere with the same ecu but different calibrations. I too am exhausted and seeing numbers at this point. Ill be looking for some mail tomorrow hopefully.

J <- Ha I'm copying you now

FWIW, I recently started doing WOT tuning on my '05 (AP Street Tuner, Perrin modified injectors w/ typical rotated GT30R and Perrin FMIC setup, Custom Perrin GT30R install w/ 3"GT housing. Pics.) and I am having the same issues. Pressure checked FMIC prior to installation. It appears to be independent of the MAF voltage and load. Related to when the turbo gets up to speed. Varies with gear that is selected....

Whew. Thank goodness we have somebody else here with the same issue. Nice. Well, NOT nice, ... but nice to know we have friends

Crystal and I were working on delaying the closed loop to open loop transition to see if this helped. We successfully delayed the transition However, as I pointed out (and as you are seeing), it seems to be dependent on MAF, Load, or MAP. This is independent of the CL-OL transition.

We leaned out my fuel curves a bit ... but I still get high 9's in AFR on spool.

BTW - I missed your initial post about your car before. I just reviewed your main post. WOW. VERY nice setup and nice car. You definitely need a bigger air filter though. I would be surprised if that air filter isn't limiting you.

Yes on the filter. On intial start up of the car with all of the new components, I used a 70mm APEXI MAF/filter kit because this is what I had in the garage (from a buddy for free) and I was pressed on time. The intention was to use it just to get the car back to "commuter mode". Since then I have added a larger K&N (not much larger though due to lack of room in the inner fender )

I am very interested to find out what what you guys discover....

In the meantime, I may put together some tubes that will allow me to experiment with blow though.

Wow very nice setup. Good luck with that tuning. Its driven me to the point of trying to decipher some of the ecu code and unknown maps in ecuedit to try and find a delay. I just glad I got most of my spikes worked out, and when I get back to my car on Friday I can begin testing some more random things to see if they have any effects. I would like to get my afr's at a solid 11 before I am satisfied. 10.9 just wont cut it

Oh yea JDM Fogs Drooling...

I may try some runs using s blow-through setup next week. Since I have an extra MAF housing lying around with the pipe size close enough to 2.5" I may try and just clamp it in between some pipes. Only problem I see in testing this is extending the MAF sensor to reach that far

[04stiguy]

Another thing to think about that is closely related to "MAF delay" is the fact that there is now a long column of air that is 12+ feet long (CAC tubes and FMIC) that was not there with the TMIC. Not only is there a greater delay from the time the air goes from the MAF to the combustion chamber, but the column of air requires a bit of time to be pressurized, similar to inflating a ballon or filling an air compressor tank. Start with 0 psi in the pipes and take it to 18-20. There may be no safe way (tuning wise) to get around it other than reduce the charge passage length (go back to TMIC or change to air/water) or incorporate a blow through.

It seems odd to me though, that this is not a known issue with all of the FMIC cars on this board. Can Christian, Clark, Scott Siegel or anyone else who has been tuning FMIC Subaru's over the years chime in on this?

What are the big tuning issues with the blow through? Idle and part throttle I would guess?

Thanks all.

I'll try to reply more tomorrow but for the moment I wanted to mention here that I REALLY like the Deatschwerks injectors. They're $399, but they give you back $160 for yours, so they're really $240... They do more testing than the factory...
