EVO 9 Beginner Mod from Ground Up Questions ECU EVOSCAN Wideband
Just spent a few hours searching through forums on doing the first mods on my EVO, had questions:
Tuning:
1) Can EVO scan flash or do I need ECU flash?
2) For an EVO 9, should I get 1.3u or 2.0?
3) Any updated guides on tuning?
4) <deleted due typo>
5) Thoughts on mitsulogger vs evoscan?
Wideband -
1) Why need to weld a bung? Cant I just replace the narrowband with a wideband and call it a day?
2) Do most people just take their exhaust to an exhaust shop to get a bung welded in?
3) What do most people use for exhausts? Sounds like Turbo back exhaust was popular, but can get annoying. Do most people use downpipe cut outs from QTP?
4) Any recommendations on best wide band? (Yes lots of topics on this, but most of them were pre 2011 and there are new combos now).
5) Does PLX work with evoscan? How do most people have their configurations?
Wiring
1) Anyone know of any guides that still have pictures on locations of firewall grommets?
Any other suggestions for configurations?

1. Evoscan is only for logging. ECUFlash is for flashing ROMs.
2. Doesn't really matter. I've been using 1.3s since 2008.
3. Not that I've seen. Tuning methods and ROMs have changed so much... impossible to really keep up. Tuning is still tuning, but the terminology in the ROMs keep changing, which really makes it confusing. I gave up and go through BoostTuning or BainsTuned
4. You need a wideband to log AFRs in EvoScan.
5. EvoScan. Nobody uses MitsuLogger. I haven't heard that name in yeeeeeeeears.
1. No. The car needs a narrow band to run in closed loop.
2. Or take the individual part in. I.E. I took my downpipe down and had someone weld the bung in.
3. Usually a downpipe, test pipe, then a catback of your choice. 3" for turbo cars. Cutouts are great for making lots of noise, though.
4. Innovate, AEM, or PLX all seem to work best. Dealer's choice.
5. Here is the list of WBs EvoScan 2.9 supports. PLX used to supported, but maybe not any more??

Omg thank you so much that explained so much to me. I am a little bit unclear on just the exhaust portion.
1) When you say downpipe, test pipe, and catback, does that mean you basically replaced the whole area from turboback to the end as clear piping?
2) Does that mean when you want to pass inspection you just swap back to stock or is there a way to pass inspection with an aftermarket configuration that still decreases backpressure for the turbo?
3) What is the purpose of replacing the whole piping if the idea is to decrease flow restriction for your turbo? Why not just take everything off from the turbo back if you're going to fail inspections anyways? More piping to decrease sound?

No worries!
"Yes" to all those questions. You would also be swapping the O2 housing portion of the exhaust, as the stock piece is horrible. As for noise, in my town ,if you are too loud, you get a ref ticket. Not fun. Plus, most people aren't into annoyingly loud cars, though you definitely can ,if you want.
Since some of the questions were unanswered or an incorrect response was given.

Tuning:
1) Can EVO scan flash or do I need ECU flash? Yes both applications can flash your Evo 9 ECU. EvoScan is a paid application that can both datalog, read, and flash your ECU. I dont think it can be used to configure ECU settings. Ecuflash is a free application that's used to reconfigure ECU settings. It can both read and flash.
2) For an EVO 9, should I get 1.3u or 2.0? It comes down to personal preference. If all you want to do is flash and read get a 1.3R cable. If you want to use ECUflash to flash and read get a 1.3U cable. 2.0 will work as well and has extra features for data logging.
3) Any updated guides on tuning? Merlin's guide : https://evoscan.com/ecuflash/Merlins...UIDE-V1.7a.pdf
4) <deleted due typo>
5) Thoughts on mitsulogger vs evoscan? EvoScan works fine. Mitsulogger was created by someone that no longer supports it. Wideband -
1) Why need to weld a bung? Cant I just replace the narrowband with a wideband and call it a day? No, you need both a narrowband and a wideband. This article has a good overview : http://www.enginebasics.com/EFI%20Tu...%20Basics.html
2) Do most people just take their exhaust to an exhaust shop to get a bung welded in? Yes,it's much easier to remove and mark where the wideband bung should be located for the welder to drill into the exhaust and weld in the bung.
If you look at the instructions for wideband installation that comes with most kits they specify where the wideband should be located.
On anEvo, the most optimal location is at close to the end of the downpipe. The wire pointed to the passenger side grommet, so it can pass through the grommet into the interior.
3) What do most people use for exhausts? Sounds like Turbo back exhaust was popular, but can get annoying. Do most people use downpipe cut outs from QTP? A full Turbo-back exhaust is the norm. That means a downpipe, test-pipe, and cat-back exhaust.
4) Any recommendations on best wide band? (Yes lots of topics on this, but most of them were pre 2011 and there are new combos now). AEM, Innovate, or Zeitronix are quality gauges that I have installed both on my personal Evo and other people's Evos and I would recommend using those brands.
5) Does PLX work with evoscan? How do most people have their configurations? No Idea Wiring
1) Anyone know of any guides that still have pictures on locations of firewall grommets? Nope but if you jack up the car and look behind the drive-shaft close to the downpipe you should see the passenger footwell grommet. That's the best place to pass a wire through into the interior.
Any other suggestions for configurations? That depends on what you are trying to do with the Evo. Are you trying to reach a specific power goal or just want to run it as is?
Its just semantics at this point. I should have said you started to answer the questions and then I added some more relevant information.
As always help me help you. Teamwork makes the Dream Work.
Meh. No worries! I was trying to keep it simple and less confusing by listing the common ways things are done. Plus I was typing on my phone ,so lengthy replies are a pain in the ***.
Nothing wrong with mow details!
Deylag:
1) You mentioned evoscan can both datalog, read, and flash, but it cannot configure ECU settings? Isn't flashing the same as configuring?
2) 2.0 has extra features??? Damn I bought the 1.3u since on tephra's website it says 1.3u is the preferred over 2.0
3) Tuning guide - thanks so much! this is awesome!
Wideband
1) Thanks for the guide
2) Thanks ! I'll look into it
3) I might just do a cut out for on the fly adjustments
4) Thanks for the recs on widebands, I'll do some reasearch
Wiring
1) Thanks for that info. I was also looking at wiring other things like the boost controller, and also how to remove the panels and carpeting. Unfortunately all the guides I've seen have broken links for the pictures. I think my best bet will be to go on youtube with some of the vloggers and see how they remove the panels to the things
I'm not looking for a specific power goal in particular. I think basically to get as much power out of it without compromising too much of the reliability on the streets as I need this car to last at least for 2 more years as a daily driver. If you have thoughts let me know! Thanks so much for the more detailed response!
Deylag:
1) You mentioned evoscan can both datalog, read, and flash, but it cannot configure ECU settings? Isn't flashing the same as configuring? You configure the files, then flash them. There is no good reason to read and flash with EvoScan but have to make adjustments in ECUFlash, which is why I said EvoScan is for logging and EcuFlash was for reading/tuning/flashing. I was trying to keep things simple for ya and let you how how things are usually done.
2) 2.0 has extra features??? Damn I bought the 1.3u since on tephra's website it says 1.3u is the preferred over 2.0 It is, according to all I've read. There are advantages to the 1.3, but it's been so long I forget what was said. Hopefully someone can chime in. I haven't found any particular reason to use a 2.0 over a 1.3u.
3) Tuning guide - thanks so much! this is awesome!
Wideband
1) Thanks for the guide
2) Thanks ! I'll look into it
3) I might just do a cut out for on the fly adjustments keep in mind you will need to tune the car differently for the cutout.
Deylag:
1) You mentioned evoscan can both datalog, read, and flash, but it cannot configure ECU settings? Isn't flashing the same as configuring? Technically yes, Ecuflash can configure ECU settings like Injector Scaling and Latency while EvoScan can't. You can use Ecuflash to change settings and then flash with EvoScan. When you start reading and flashing your ECU you will see why it's useful to switch between both rather than just use one.
2) 2.0 has extra features??? Damn I bought the 1.3u since on tephra's website it says 1.3u is the preferred over 2.0 That's great. 1.3u doesn't have any problems flashing and will work well.

If you have thoughts let me know! Thanks so much for the more detailed response! You can get decent power with just a few mods. Usually boltons like intercooler pipes, intercooler, injectors, ebcs, air intake, turboback exhaust, o2 housing, and E-85 will be good enough to get you beyond 370hp.
