Finally got my Evo

[goodhart]

Tune just got moved up a few days. Was scheduled to go in on the 22nd, I'm now going in on the 18th. :D

Apparently some über rich dude is flying a tuner in for the day and renting DB's dyno for the whole day to get his BMW tuned. Shane, Danny, and the crew have been awesome to me over the years, so I gladly moved up the appt. for them. This way I can get some E85 action 4 days earlier anyways woot!

Yea, there was a short while where I wanted to give up, then the $376.70 price of a new front o2 sensor crossed my mind O_o
$50 Bosch universal 4-wire works perfectly. Otherwise OxygenGeeks has a direct-fit for ~$60.

Another thing I forgot to mention was the Synapse BOV. When I installed it, I was having some pretty bad surge around 4k rpm and up. I followed the directions I found from other people running it and Tee'd in the C port to the Compressor housing/MBC line, and the A&B ports in a Y connector and ran that to the stock BOV vacuum connection that runs along side the valve cover. This morning I decided to experiment a little with different ways to route the A & B ports. Some people were having better results only using either the A or B port with the other open to atmosphere.

First I tried running only port A. it felt good, there seemed to be a little 'leak off' of boost(for lack of a better term I guess) in partial throttle acceleration, but almost no surge.

Second I tried port B. There wasn't as much boost 'leak off', almost none actually, but the surge was back just like when I had A&B hooked together.

I decided to run port A to the stock BOV vacuum location and feels good. MUCH less surge than with the stock BOV in high gear (5th and 6th mainly) while at low speeds. Overall, for $80 spent on the thing I am happy with it so far.

$50 Bosch universal 4-wire works perfectly. Otherwise OxygenGeeks has a direct-fit for ~$60.

Thanks! I'll keep that in mind if mine goes out

Ok, when I click on the above link which I have labeled "patch" it brings me to the thread, I click the link, do the download using WinRAR, open the xml file and it gives me like a half of a webpage with an error. The only code I see is:

<table name="Rear O2 Heater Patch ROM Addr" category="Front/Rear_O2" address="2dc50" type="3D" level="1" scaling="H...

Is there more to the code I would assume? It looks like it was cut off with the "..." at the end. Does anyone have the whole code they can just copy and paste for me? Hughes, scheides either of you guys still have any of your old roms? Shane? Anyone? lol

If I can't figure it out, I'll just say screw it and do the 10kohm/.25 amp resistor all old skool like. ;)

Can't you just turn on the rear O2 simulator in Tephra?

[goodhart]

Yes, but you still have to deal with the O2 heater CEL as well

[scheides]

Open the XML files with notepad or a basic XML editer, not a webbrowser.

If you have any current version of tephra, it will have the rear o2 sim patch (and be an option under tephra options). Then for an IX the rear o2 heater bypass is just a simple bit change....look for a thread by mrfred titled something like 'looking for an Evo ix owner to test...' and look for some confirmation posts by me for it working on Hughes or rosey's car. Lmk if you can't find it.

Edit, posting from phone sorry, looks like above link is right!
