phish27134 Posted April 22, 2021 Share Posted April 22, 2021 I'd like to add an innovate WO2 sensor per their instructions, it needs to be post turbo before any cat at a length of 24in from the turbo due to heat? from the turbo, the OEM down has a (pre-cat?, if someone could provide me an understanding of why and what purpose it serves. Irregardless, I've seen many invidia downpipes with an extra bung for the sensor right in the bellow just before the pipe reduces, usually on the high flow catted ones, I could careless about a cat. I've read because of the way subaru routes their piping for the exhaust its cool enough temp wise to place the bung in the bellow. Looking for suggestions, I've seen no name catless down pipes, but heard do not buy, is Megan Racing any good? I know the cat can be hollowed, but read it was unwise. Any suggestions comments or criticism are welcome On the innovate website is the manual, if anyone needs more clarification. This is for tuning purposes so I'm going to post in there as well I apoligze if a copy in in a wrong thread. -Thanks in advance Link to comment Share on other sites More sharing options...
Max Capacity Posted April 23, 2021 Share Posted April 23, 2021 Sorry but IMO, if you can, send that back get your money back. You really don't need that. In the race car we did have the wide band just after the turbo. These cars work great with a Cobb APV3 and a custom tune for y our car. My wagon had been on Cobb AP since Dec 8 2004, The Cobb AP stays in the box it came in. no reason to keep it plugged in or monitor things. I understand you want to keep an eye on things, back in the 1970's I had direct reading oil pressure, water temp and oil temp gauges and a Sun tach in my car. In these cars, you don't need to do that. Keep your life simple, put that money towards a great tune. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...
phish27134 Posted April 26, 2021 Author Share Posted April 26, 2021 When I purchased the car, it came with a V2 Accessport, which I realized I, never looked but some differences between the V2 & V3. I had just had a 07 spec b with 300 @ the wheels, no injectors, no fuel pump, stock exhaust, cobb cold air, vf53 swap with an open source tune. On sport sharp it MOVED.......I have the dyno too and copied the rom. Tried to replace on my 2008. 07 open source was done by a well known tuner and his education of subarus is immense. I asked about certain mods, he could have sold me own, but was completely honest and said u dont need that because. I know tunes are vehicle specific, but with Ecuflash/Romraider they both show the same ecu is used for both, which I thought odd unless maybe it was a alte 07 and early 2008. So I was unimpressed with cobb, I had the option of a few maos, all caused overboost, Im not buying a boost control as I made a lot more HP and didn't need one. I've since added an invidia catback, but the car has the identical ecu map, no missing every para matches up. As far as mods on the 07 all I know, is cobb intake, and vf52, which boost seems to come too early and too fast? Wastegate settings. I've used direct copes of the ROM, rescaled the maf I don't wanna mess with timing, but I noticed in my logs some anomalies. Would you wind taking a look at the rom? I've modified so it has significant changes from the original tuner, any assistance is greatly appreciated Link to comment Share on other sites More sharing options...
Max Capacity Posted April 26, 2021 Share Posted April 26, 2021 (edited) I'm not good with reading the MAP. I suggest you make a post in the 4th Gen forum asking for help in this thread. You can link this thread there. I trust you have done the simple things, clean the MAF sensor, zip tied all vacuum hoses, don't a boost leak test. My wagon doesn't have a boost controller either, but Mike of Tuning Alliance did put one on my 09 Spec B, which still has the vf46 on Cobb AP.
