What kind of driving does that represent? I used to get 25mpg on my tuned EJ205 combined highway and city with some full throttle mixed in. I hope the EJ207 isn't much worse.

That was mainly highway with a few spirited pulls mixed in. I drove from NWCT to Queens and back

Ok I'm a little confused... The avcs wiring that was included with my swap has two connectors to the ecu. But the DS1 wiring guide only mentions one if them...




added: This is what was included. It doesn't look like the pins match up at all with the DS1 instructions.. I have no idea what to do with these...






edit again: So I feel pretty damn stupid.
http://forums.nasioc.com/forums/show...5&postcount=28
I was looking at the ecu plug backwards from the diagram! LOL It all makes sense now.

The wires given to me are the ones that need to be added in the DS1 instructions. It appears as though I can splice the wires from my usdm connector to these and then just run this whole harness. I would still have to modify the TGV black harness in the engine bay. But shouldnt be too hard:http://forums.nasioc.com/forums/show...1&postcount=58

Hope that helps clear up anyone else's confusion lol

I was wondering about this too when the supplier sent photos and "instructions" telling me to just use the same pin locations as the "AVCS harness" they send. I'm pretty sure you're still going to have to re-use your TGV wires on the side you simply re-pin. Then use the 4 wires plus ground pin from the provided harness to wire up the other side.

That's what I plan to do anyway. I haven't received my wire harness yet to compare the pin locations to my research.

FYI, you might need to do some additional work to make that 580 ECU run right. I've read something about the possibility of grounding out the #1 pin to make AVCS work. Just what I've read, hopefully someone else can chime in.

Oh geeze. I'm just confused as ever about this wiring crap. Idk what you mean by grounding it out. But I'll look into it.

If anyone can make sense of that, please let me know. I don't want to have to remove pins and replace them, etc, if I can avoid it. I'd rather not destroy anything lol In the mean time, I'm going to lose some sleep trying to figure this crap out.

Sorry, I don't want this to be the blind leading the blind haha but it doesn't make any sense to me how they could suggest you can run AVCS from one engine connector when every wire reference shows 2 engine connectors, one on each side! I just wanted the "AVCS harness" so I could see how hard it's going to be to de-pin the connectors. If I can't do it then ill buy the harness I know works.

PM me and I'd be happy to collaborate on research. I'll be curious how everything goes for you since I'm right behind you.

hahaha yea we don't that. De-pinning seems to be the hard part. I believe the IAPerformance kit is just shielded wire and the pins. You just re-pin and go. I emailed IAP and also my engine distributor about a guide. Hopefully one of them will reply with something positive. Otherwise I'll try to figure this out and will definitely PM you if I make any headway on this.lol

with the talk of fuel mileage, we should be mentioning what transmissions we're on. i typically see between 16-20mpg tank averages with a jdm 6sp and a mix of rural/highway driving. when i switched transmissions from an '02 5sp, i saw a decrease of about 3-4mpg due to the shorter overdrive gear.

Arent 2.5 conversions hella expensive? I've heard its so expensive its almost not worth it. I've heard some say youre better off doing a 2.0/2.5 hybrid

Don't do what? If you have the DS1 instructions you have all the guide you need. If you're distributor is Robert from JDM racing motors he'll tell you to put the supplied wires in the same pin locations on your harness but to my knowledge, this wont work cause you only need to add pins to the one ECU connector, not two like the harness provided and additionally, you still need the other engine connector pinned up too.

Anyway, you've essentially been supplied "shielded wire and pins," you just need to de-pin what you have and follow the DS1 instructions. You might even have enough conductors to add the unsheilded wires from that harness in place of re-pinning the TGV wires.

I'll PM you too.

Would mind picking up a case of 5w30 brad penn,amsoil ect that way I can run that weight in both of my vehicles

Yea my best was a trip down to NC where I averaged ~26mpg on the stock 04 5 speed. Basically every other tank I've had has been ~22mpg. Which do you feel is the bigger hindrance, the stock twinscroll down pipe or the stock intake/intercooler? (I should mention I'm on a UDDM STI top mount)

5w30 10w40 ect..

I am not a fan of the rotella in these engines. This was first made popular probably many years back by Ron At axis. He used that oil on race engines that had very loose tolerances and pistons that slapped around in the bores and ran very rich AFR at high boost. I have seen this oil come out as thin as tap water after use.

I think 5-30 is to thin for the 207. I have seen way to many bearing failures with it. Keep in mind that alot of "special" oils will be at least one step lighter viscosity that advertised. Look up some UOAs of the oil in question. After being in thousands of cars with oil pressure gauges, I would run 10-30 winter and 10-40 summer. OR a good 5-40 is fine like Castrol. The lighter the oil, the less oil pressure you will have at redline on these engines. You CAN, Take the oil pump apart and shim it so it will run higher pressure with the thinner oil.

When you see the oil pressure run 90 to 100 with the heavier oil and then see the pressure 60 to 70 with the light weight oil, Then you will probably agree with me.

What runs the coolest oil temp and what does not burn off is what you should run. If you have to add oil in every tank, then switch brands. The Motul burns off and the Castol does not in my personal engine.

I would say downpipe and optimizing the tune.

Would any of this really make a difference if you keep the car in closed loop? I would think aerodynamics/wind, gearing, and weight would cause the biggest differentiation in mpg. Basically minimizing engine load...


PS - This episode of Mythbusters gives you an idea of just how much aero/wind can affect things:

So I just bought the last Purolator pure one pl14460 from sears. They said they won't be carrying it anymore and they are the only place in town that did. After this can I just use the pl14410 (sti) filter? It's much smaller...
