Oh alright. Well after the holidays I should be adding support for that.

Think the SD rom is set up to drop the af when you let off the throttle because of the Anti lag function? Or is this Because peoples SD table is not set up correct? I don't remember seeing the off throttle af deal when I ran the rom, does it only happen in groupn mode maybe?

From some logs I was doing yesterday, the ipw and isvc do definately go up for the antilag function anytime grpn conditions are met and ign falls below 0 degs.

Jerod helped me test some fixes for the CEL issues today. I was able to eliminate all the codes, but the CEL remained on. Which means it is not due to a code being set, but some other issue. It could be something like the check engine light using a different pin on the JDM ECU as compared to the USDM. Or some other unknown logic that causes a constant CEL. I don't have anymore time to mess with it, however.

In the jdm cars i have ran this map on, the cel seems to have a mind of it's own, sometimes on and sometimes off. When on, code retrieval yields no stored codes. Anyone yet gotten a hold of the jdm wiring diagrams??

Thanks for all the great work guys, a Merry Christmas and Happy New Year from Africa....best wishes at Cobb tuning merchgod.

I have the jdm diagrams. It uses the same pin for the cel as usdm.

Cool, any chance of getting pdf copies of those? Looks all through the net to no avail. Thanks.

Hi guys, i had my blow through maf tune pretty perfect for my car, but decided to try the SD2002 rom out that Jerod posted awhile back and, well, WOW, quite a noticeable difference in throttle response and smoothness. I noticed that when mode byte was zero it almost seemed like LC was active b/c the car would hold at about 4000 rpms and build boost at a stop. I also have the brick wall issue at about 4k rpms probably b/c of the TGVs (9:1 AFR) which will be modded this weekend. I think i might give this a go tuning wise. My injectors are scaled up to 825cc from the 760cc flow rate, frommy reading i should start with the 760 scalar? and can i reuse my latencies from the maf tune, they are spot on? if not whats the procedure for this. Most of you are using EJ207s and 257s and mostly E85, guess i wanna give this a shot too on 93 octane, and if needed i have 100 octane available, no E85 yet available

. I uned the coil dwell back to stock values, zeroed out WGDC, turned down ign. adv., changed my scalar to 760cc, latencies, tipin is what i had for the maf tune. Anything else that should be tuned before i start rough tuning this rom? which timing table is used A or B? Thx. I read a lot of the threads and am very excited about the future of potential for this rom.

I cant agree with you more this is really exciting stuff and i cant wait to get it working properly. The idea of a switchable map really does make sense because most of the gp.a and WRC class cars are able to switch to a 'road' mode between stages so why would the gp.n version not have a similar feature to save the engine, fuel and other components.

You should read through the thread on NASIOC in the engine management section called "OS Speed Density - Discuss Here" it will answer all of your questions.

You can find RHD 2004 wiring diagrams here: http://mustakaapu.kyla.fi/~beavis/RHD_2004_subaru_DOCH_Turbo_wiring_diagram.pdf

Can't confirm for sure that they match JDM version 100% but those were ones I used to track differences between JDM vs EDM and so far each pin in RHD 2004 diagram has matched my JDM v7 ecu. Would it be possible that AUDM, UKDM and JDM use same ecu pin outs?

EDM 2005 wiring diagram for reference:
http://mustakaapu.kyla.fi/~beavis/eudm05%20wiring%20diagram.PDF

And differences between JDM and USD ecu pins:
http://mustakaapu.kyla.fi/~beavis/Subaru_02-05_JDM-USDM_WRX_Pinouts.pdf

Seems to be using same pin for CEL in all ecus.

Awesome work guys lets keep it coming please.

Does anyone have this ROM running with the proper ecu AND the IC Autowash switch wired up and functioning?

I have the proper ecu, but wired a switch instead of the button. But can hookup the button pretty quick.

Let me know if I can be of help.

Got three 03 / 04 JDM stis with this roms running here with the OEM IC Autowash all working ok and triggering on the ALS and LC when on. CEL stays on sometimes and other times off.

I am wondering if those of you that have the button could read the CEL that comes on occasionally for me. I am trying to work out a fix for the USDM guys and I'm pretty sure I know what's going on, but my test mule's car seems to be throwing injector codes now so testing is becoming difficult

I only get a CEL after a reset/reflash, which goes away quick.
