Limited came with VF30 Same engine codes and presumably same longblock internals. Based upon my research, the cams in the V7 Spec C=V8 STI, V7 Spec C RA=V8 Spec C. Simply repeating what I have read on here and through various vendors. Would love to get confirmation so I can purchase the correct cams. Then again, will a cam upgrade to V8 Spec C make a significant difference in the powerband? Not looking to win track racer of the year. ![]() However, I'd like to upgraded cams now if they will be a better fit for a GT30R next spring or farther down the road.

It sounds like I have to go UTEC with 272 cams though and I don't know how I feel about that a UTEC without doing research to see if I will pass emissions in NJ. |

![]() I dont see why you would "need" a utec for a cams....can it even control the avcs?

For cams... you need to do some kind of tuning. UTEC is probably the most cost effective and flexible way to go about it. From there just use openecu to flash a new AVCS map if you see fit. For the record, I have left my AVCS map alone... although I know clark has a map that works better than stock both down low and up top. def |

![]() A while back the problem was the stock MAF would be maxed out with a larger sized turbo. I'm not sure if that is still the case any more but I intend to run my UTEC with speed density. I also like the on the fly map switching and additional spare solenoid control ability of the UTEC.

![]() Ah, so it seems that you have to use MAP when MAF is "maxed" out and the stock ECU can't handle MAP so a UTEC is necessary to handle MAP. Would like to hear more about your workaround. I could search for it, but I am curious about your experiences.

![]() Don't most people go to a big maf intake setup when maxed like kstech. Or a groupn rom uses speed density, and you can opensource tune that. Just saying my car was never as smooth as it is now on opensource when I had a utec tuned by Phil .

![]() big maf setups are an option, also blow through maf. I've heard the groupN rom works but supposedly can't past ODB2 inspection which is a concern for daily drivers.

![]() Big MAFs are on the scary edge of any meaningful resolution... speed density is probably the best reason to UTEC it. anything over 30R and up is gonna push a big MAF too close to the edge.

here you go, i had the page bookmarked: http://forums.nasioc.com/forums/show....php?t=1363692 it runs just fine for me. it's true, i'm halving the resolution of my ecu, but i haven't seen any negative effects from it. i'm also running a custom big maf (83mm) intake. |

![]() any advice for a aftermarket ecu to run a V7 207 with avacs? I didn't see much for standalone recomendations.

http://www.linkecu.com/products/engi...ecus/g4-xtreme I've been running mine for about a month now and have no complaints with it. The software is very intuitive and the box has plenty of I/O. Driveability is head and shoulders over what I had with my "Gen 1" (Version 6) EJ207 ECU. I've run a number of standalones over the years, from beta testing the UTEC (Hi Def! :wave: ), to beta-ing the Gen 1 AEM EMS, FIC, MAP-ECU, Motec, Power FC all the way back to Accel's first DFI setup for domestics. The Link is my favorite thus far. It all really boils down to the interface. PC-Link can be downloaded for free if you'd like to play with it. As for the price, I would suggest shopping around. I'm into mine for around $1500 delivered. That was with a 4 bar map and a MAC BCS. I already had an Innovate LC1 in the car and a spare GM IAT in the garage. The rest of the sensors are all OEM. I made my own jumper harness between the Link and my OEM harness as my application/needs were unique. Tuning is a snap, we had the car 90% dialed in in one day, tuning on the street. I live in Japan, paying for dyno time out here is ridiculous. If I had (cheap) access to a set of Dynapaks, it would have cut down tuning time tremendously. If you have any questions, feel free to ask. Ryan |

![]() The link G4 is nice.
Also you can call Phil at element and get a hydra that will plug in and run the AVCS. C |

![]() thanks ryan, I've got a legacy twin turbo 207 in my 02 wrx that was in it when I bought it and as far as I can tell it still has the stock ecu. and the avcs harness isn't there. so i've been dreaming about fixing that for a while now.

![]() Got my v8 Ej207 tuned last week. Now let me prepare you first...... I went into this tune with the goal being to have the car safe to drive/conservative and also to find out any problems/things that need to be addressed. It was also 90+ degrees and humid as hell.
![]() The tuner said that he believes the problem to be the turbo, it was taking forever to spool with 20psi not coming until 5k+ rpms......... which destroyed the torque curve. The engine temps were also a big problem as the MAF was reading around 140+ degrees. The car doesn't have any heat shields on the turbo which is a big problem for under hood temps. So while the numbers were nothing to write home about....... we now have an idea of what needs to be addressed so that next time we can make more power. It was nice to see how it pulled all the way to 7600rpms though. Here is the video of the dyno run. Also, I was talking with the tuner in regards to speed density vs MAF and he told me that speed density is more of a pain because you have to recalibrate it every time the weather changes ![]() ![]() I think I might just go back to a VF36/37 until a better TS option comes out. EDIT: Here are my mods. MRT TMIC Hayward & Scott Downpipe MRT catback, cat in midpipe (need to get rid of that) I also notice the exhaust has a narrow section from when they did exhaust work..... looks like it drops down to a 1.5-2 inch pipe for a 2 inch section. Turbo inlet hose Blitz SUS intake cobb pulley VF37 converted to PE1825 by deadbolt with clipped fin/port polish/heat coating Open source tune ( I have a Utec sitting in the garage) Stock BCS Last edited by LIQUIDSK8S; 09-18-2010 at 12:19 PM. |
