  1. OK, thanks for the info. I'm not sure if I want to rig something up to power it through a spare set of leads, or just wait until it's installed in the car and worry about it then.
  2. I have a V88 that I bought from a guy way back in 2013, and hopefully in the not-too-distant future I'm finally going to put it to use. The guy I got it from said it had never been installed/used, and I've never done anything with it, so as far as I know it's got the original firmware on it. The sticker on the ECU says: PCB Rev 1.2 Serial # 8219 So, first stupid question - I've found the firmware page (https://www.vi-pec.com/software). Do I need to download/install any intermediate firmware versions, or can I just download and install the most recent firmware and be good to go? Next stupid question - I'm still in the process of re-installing the main wiring harness in the car, getting the battery reinstalled, replacing battery and alternator wiring, etc etc. Basically, I can't install the ECU in the car yet because all of the supporting wiring harness work isn't done yet. So can I just plug the ECU into my laptop and update the firmware? Will the USB provide the power the ECU needs? Or does the ECU need to be in the car with 12V applied in order for me to do this? Thanks! Pat
  3. I'm doing an EZ30 H6 swap into my '97 Subaru Legacy, which originally had an EJ25 H4. Can the V88 convert the tach output so the 4cyl tachometer will display the proper RPMs for the 6cyl? Or will I need to set up a separate tach converter to do that? Thanks!
  4. I'm in the "figuring out pin-outs" stage of installing a V88 in a Subaru Legacy to run an EZ30 6-cylinder (as seen here). One thing I'm trying to figure out is the AUX output(s) for the idle speed control. The ISC is mounted on top of the throttle body and has three terminals: Section 9.4.2 of the V88 manual discusses how to set up a 3-terminal ISC. Section 9.4.5 specifically talks about a Subaru ISC, but that's an older style, which was mounted separate from the throttle body. That older style of ISC appears to have worked the same as desribed for other 3-terminal ISCs in Section 9.4.2 (based on both the discussion in Section 9.4.5, and old wiring diagrams for Subies that used that style ISC). The ISC I've got is wired differently, according to the EZ30 wiring diagram - the 3 terminals are: Power Ground ECU That makes me wonder if it behaves like a 2-terminal ISC, but just has its own ground, so I would only have 1 AUX output feeding the ISC (as opposed to a "normal" 3-terminal ISC having both AUX1 and AUX2 wired up to it). Has anyone seen a 3-terminal ISC, Subaru or some other brand, that doesn't operate like the 3-terminal ISC example provided in Section 9.4.2? Should I just wire it up like a 2-terminal ISC per Section 9.4.1? Thanks!
  5. I've been registered here for a while, but as a reflection of my progress on my project , I haven't actually done anything on the site. I have a '97 Subaru Legacy 2.5GT, which has done daily driver / auto-cross / track day duty for me since I bought it in 2000. The late '90s 2.5GTs were non-turbo, with the DOHC 2.5L EJ25D rated at 165/162 hp/tq. Over the years, I did a variety of modifications to the original EJ25D - ported heads, reground cams, header, etc - that resulted in a significant bump in power, to something around what a stock 2.0L WRX puts down. Yes, I realize many would think that was a poor ROI compared to just doing a turbo swap, but I've never had any desire to go the turbo route (note the license plate in the above pic). However, more power is more better, so at some point I started thinking about swapping in the EZ30 6-cylinder from the Outback. Initially I was planning to use the 2nd generation EZ30, commonly called the EZ30R, which was offered starting in '05 in the US. Rated @ ~245bhp, DBW throttle body, variable intake cam timing and lift, blah blah blah. I picked up a very lightly used EZ30R years ago and was intending to swap that in the car. Since the 30R uses a CAN-bus type ECU with an Immobilizer, it's very challenging to use the factory ECU (I've only ever seen discussion of 1 person successfully accomplishing that), so I picked up a Vipec V88 to run the engine. 4 years ago, I was still running an EJ25D, planning to do the 6-cylinder swap "some day". Then I managed to hydro-lock the EJ25D , and suddenly it seemed like it was time to do the H6 swap. Unfortunately, I had run into some issues getting the 30R cylinder heads worked on by a shop, so the first H6 I had purchased wasn't ready to go. I came across a great deal on a used 1st generation EZ30, commonly called the EZ30D, so I bought that and rebuilt it. The 30D doesn't have the fancy variable cams, is drive by cable, and is only rated 212hp. So, I proceeded with the swap, and mechanically pretty much got things done as of 2-1/2 years ago: I had spoken with a Vipec dealer / tuner here in the US about installing & tuning the ECU for me - he was only a few hours away, so it would've been quite convenient. Unfortunately, by the time I finished all of the mechanical stuff, and then had to pack all of my stuff and relocate due to a change in duty station, he was no longer in the Vipec business. Well... damn. Thus began the long, stagnant period, during which I ignored the thing and hoped that the wiring harnesses would magically merge on their own. That has still not happened , so I might actually have to do it myself! I've gone through the Subaru engine harness wiring diagram and created a nice Excel spreadsheet of everything. I had sourced a complete main dash harness from an '01 Outback; I've culled that down to just the connectors that plug into the engine harness, each with long pigtails for merging purposes. Now I just need to figure out matching up the EZ30D pinouts to the V88 pinouts, some of which is pretty obvious, but other stuff I need to do some homework. And then I need to actually merge the harnesses, something I've never undertaken before. At my current pace, I'm reasonably certain I will have the project completed at some point this century, maybe even this decade.
  6. Bumping an ancient thread here... Not sure if Ben is still active on the forum or not. Here in the US, we didn't get the EZ30 until 2001, and had that version from 2001 to 2004. Since our Subaru model years are typically a year behind the Japanese and Aus/NZ markets, it sounds like it's probably your '00-03 "phase 2" EZ30. (No AVCS or AVLS, cast aluminum intake manifold with variable plenun / IRIS valve, single exhaust port on each head - is that what your phase 2 motor has?) In the not-too-distant future I plan to install an '01 EZ30 into my '97 Legacy using a Vipec V88. It would be great to be able to pick the brain of someone who has already done something similar.
