When I get some time ill try and get a sound clip. You will love the sound of the catless dp. And my car sounds different than the other 207s in here cause the 32 bit. You can actually hear my avcs kicking on decel.

Does it really make that much of a difference? I have a v9 but with v7 ecu.

not really^ only a few changes and its got newer maps for the newer intake setup. it can all be tuned or copied over if you want certain things from the stock rom maps provided on romraider forums. just got to search. if you search hard enough you can find the S cars stock roms. some nice changes to avcs and timing! but then again i use my own timing curve that is smoother than a babies bottom!
i agree about all the problems that are so simple and painful to have to read. most of it should be in the basic part of the ej20 section since its not engine specific but rather a easy problem and search function in there could clear up. kinda why i flipped out last week w/ something so stupid. 80 pages of crap since i put my engine in feb. which btw only took me 4 days to do myself. engine arrived monday after. had it in thursday up and running w/ avcs wiring harness i make installed as well. 3 hours a day after class.. plus a few hours on the lap top tuning. really should not be as hard as ppl make it but then again some ppl have never turned a wrench this far into a car...... if anyone in the Wisconsin area wants a tune i can hook you up on a wrx ecu or jdm ecu. im pretty cheap too. just no real dyno numbers. then again there is always the virtual dyno numbers. |

Honestly im one of those people putting too much into this thread. I'm just so annoyed with where I am with my car and this is the best place to put it. Sorry. This thread describes where I am so hopefully I'll add something to someones research but most of my posts are coming me being annoyed with where I am with things. My b.

It Does make a difference when you are running a factory usdm forester 32 bit ecu on a v9 engine that was meant for a 16 bit. I have more random tables and emissions **** built into my ecu. So I get the weird rolling idle issue when I down shift or let off. I am also on a Dbw ecu so I get some odd noises hear and there. but all in all it is amazing and a blast to drive |

Yea I was thinking about that after I posted. Somebody else needs to get his swap done to see if his car does it too!

I just extracted the stock AVCS harness that came with my swap, but won't be needing it (already bought one before hand). If any of you are interested in a factory uncut AVCS harness... I listed it here in the classifieds

I am currently trying to get my v8 into the car. Its an 02 and im using the stock 5 spd transmission.
I can't get the turbo to clear one of the ribs on the transmission when trying to get the two to mate. Do I need to take the turbo off or is there something I am missing on getting the engine to attach to to the car? |

I thought the same thing at first but was able to just wiggle and finagle it.

Hmm. I guess I need to get down there and try again. I did have one of the long studs get bent, so I replaced it with one from the old motor and I hoped that would give me clearance, but it didn't quite give me enough.
I also have one dowel stuck in the old motor. hopefully I don't need it that much. |

The turbo to 5spd tranny clearance is a tight fit. I am able to leave the turbo bolted up during my installs.
I do not have the studs installed in the motor. I installed them after the motor is mated. Just make sure you have the angle correct on the tranny and with the motor on your hoist. With the correct angle it becomes real easy by yourself to get them close to mated, then a little wiggle and the turbo clears the tranny. |

i know its the wrong place but a lot of you guys want this option for your cars.
got a blouch dom2.5xtr w/ only 10 min of idle time running. never drove it down the road. off a friends car that couldnt not afford to keep the parts so i bought the parts off him. its single scroll. basically a brand new turbo! 10cm hotside Also have a blouch dom1.5xtr single scroll. has 10k miles. very clean as well. shaft play on it is the same as the dom2.5 i have above w/ no miles so its good to go! if you want twinscroll on this you can get the TS exh housing from blouch for future use! both flow 49lb/min so good for around 400whp. dual BB center sections. liquid cooler w/ sti oil feed lines! have a 2011 sti tmic to go with either of them and brand new in box ID1000 topfeeds w/ the same 10 min of idling time. i just dont want to do the build before winter any more and one of the turbo's has got to go. preferably the 2.5xtr. |

I have a pipe for my intercooler with a place for a maf sensor that would make for an easy relocation of the IAT sensor, putting it right before the throttle body. I originally bought it to do a blow through maf setup, but with all the advancements on the SD front, I have considered going that route. I saw a post a year or two ago that you were not thrilled with the open source 16 bit speed density tuning yet. Has this opinion changed at all? Do you see a benefit to running SD with a MY03 EJ207 w/vf37. I may end up picking up a larger twin scroll turbo in the future if that makes a difference. I'm wondering if SD tuning would possibly improve any of the "cons" of runing E85 in colder climates, like extremely poor cold start idle, and idle hunting during warm up. |

I have been running the SD rom on my car for 8 months as a daily driver on the 207(and a year before that on the 205), no startup issues with e85 or idle hunting on warmup. As it gets colder I will have to tweak the cranking tables but it is fine now in AZ. Fueling is spot on and car makes great power while being very smooth on or off boost. It solves several little drivability issues I find really irritating on MAF cars, not to mention it gives you all the other fun features.
I have found most of the startup issues with e85, particularly the idle hunting on warmup, either on MAF or SD is due to bad latency settings, basically bad interpolation of manufacturer data or plain wrong absolute values. Last edited by lukeskywrx; 10-22-2012 at 07:53 PM. |

I'm talking coolant temps under 30 or 40. the ARF trims swing back and forth back and forth till the coolant gets up around 100-120 and it smooths out. I've had the same idle hunting on warmup with very cold coolant through 3 different tuners over the last 3 or 4 years, so I'd like to think they dont all have the same wrong latency settings. I'm using DW850s, so it's not like they are some obscure injectors or anything. I'm not saying thats not it, I would actually be thrilled if you were right about that. Which injectors are you using? |

E85 gets even trickier because of the poor low temperature volatility of ethanol below about 70F. When you design your startup routine you have to provide enough gas to do all the starting and initial warmup till the engine gets hot enough to vaporize ethanol right around the 100F range you noted. Winter blend e70 helps the startup problem but now you have to know what your fuel is and what map you are running. I run ID 1000s, running the manufacturer latency I get horrible warmup idle hunting, increase them by 5% and it all goes away and the car is much smoother to drive. Some day I will build my own injector test bench and really get to the bottom of this. |

I gave them a call and no luck Jspecauto/JDMracingmotors said they don't have one for me either. Checked Ebay and made a few calls, but am coming up empty handed. Short of someone on the forums having one, not sure where to go from here |

I think I've been looking in the wrong place all along. I kept thinking something was happening inside the maps warmup routine around 100 that changed and smoothed things out. When really maybe it's just the fuel itself naturally vaporizing properly around those temps. Wow. Thanks for the insight. So to start testing your theory how would you recommend I proceed? Try bumping up the latency like 2% across the board each morning and see if it improves? |

i have tuned one car thus far on SD. its a ej257 w/ a BW 600whp turbo. did it on pump, then race, and now e85. i only have problems w/ ****ty idle because the injectors are 1600's from five o motorsports. i fixed it by choosing the section in the primary OL tables to a arf slightly lower than 14.7 and then set min OL arf to 14.7 so its always in OL while idling. I just then took some fuel out of the SD table in that section to get the afr back up around 15.0. also have fuel learning values set to zero so it cant do what it wants in closed look. its basically a race car around 550whp right now so fuel mileage is not the best but i have ran my maf based ej207 around 15.3 afr crusing/idle and it runs very smooth. why burn fuel that isnt needed. i relocated a iat to my throttle body in a tricky location between the map and iacv flat part and round part meet. its tight in there so when it idles the iat sensor has air flowing right by it and into the controler and then when the throttle opens the butterfly swings away from it and air goes zipping by it. its the stock iat sensor from a old maf i had and it seems to work pretty good. i would do the blow through trick and use just the iat if i didnt love my process west tmic so much. got it a month ago for a steal w/ splitter so wont be making a v mount kit anymore. spring my car will be full time SD. right now its only SD on the weekend a few times when i tinkered with the fueling tables and timing compared to manifold pressure rather than engine load. for someone who has a turbo that does not taper the lines on the 3D timing map need to be redone because it doesnt follow the loop like it does with engine load increase and then decrease on load based maf roms. still fun stuff! |

So im looking at getting an oil press gauge and have the JDM sandwich adapter on there already. i searched and only had one person say they thought it was 1/8npt. can anyone verify so i dont have to wait on the correct one if it doesnt fit?

The first engine I got had one in it. I no longer have it but.....Its definitely bigger than 1/8 npt
Try going to a local hardware store or even auto zone and get a brass 1/4" npt/hose barb fitting. They're like $2 and will give you piece of mind Or try threading some 6mm/8mm bolts in |
