EJ207 Owners?

[D-Rodman]

I filled up both my cars last Sunday in anticipation of the weather. The gas stations near me no longer have fuel to sell or have mile long lines to get fuel. I have 3/8 of a tank left on my saabaru and 3/4 of a tank on the bugeye. Trying to avoid driving the bugeye, got two appointment cancelations from EFI logics and the car runs rough, really needs a tune. I have the wideband working so I can keep it on or close to 14.7 as much as possible but rolling to a stop the idle stumbles to almost stalling before it recovers to normal idle. It struggles for a few seconds, goes lean before if recovers and idles at 14.4 - 14,6. I live in Suffolk county but have a business in Nassau county, Long Island. It's a 20 mile ride each way. I normally get a full week out of a tank on the saabaru, the bugeye use to burn a bit more with the tired old 2.0 before the ej207 swap. No idea what fuel consumption will be with the 207 on stage 2 level tuning. Saabaru is tuned with an accessport, stage 2 and has 140,000 miles. It's been we'll kept since new and 100% reliable.

Sorry, could you remind us again what your setup is? Did you put on a Forge wastegate actuator?

Nevermind... 16g. yea I can search

I had a nice long visit with the guys from Kamak this past week at SEMA. Nice guys and I'll definitely be talking with them more when I grow tired of my VF36.

I couldn't get them to commit to ball bearing though... I'll work on them.

Numbers look good.

a 16G w/ almost 400 whp and 400wtq? or is that brakehp?

[WRXt4cy]

Question for you guys that are running E85 with the EJ207. What kind of fuel economy are you seeing with mixed driving and with highway only driving? How many miles do you get out of a tank?

I'm looking into getting an EJ207 swapped car and want to know what to expect. I run E85 on my 2011 STi so I know there's quite a reduction but I want to know how the 207 does.

If people could chime in about what tranny they are running, that would be helpful as well.

I searched around and couldn't find anything other than a few people that complained that the 207 gets poor fuel economy in general. Not sure if that's simply due to its design or the gearing in the JDM tranny that they were running.

Thanks guys. Hope to be joining the 207 club soon.

I don't want to ignore your question because I'm one of the guys running e85, but to be honest I haven't even kept track of the mileage. My car had one purpose - to be fun and fast. I have 03 WRX as a backup for long trips and the winter. I would be happy to record some data for you if you'd like, but also keep in mind I have a 07 sti trans so the gearing is different than most jdm setups.

I'm very curious as well. I will be swapping my 02 wrx 5MT with a USDM 6MT. I dont want the shorter JDM gears. I'll be curious what type of milage you are getting.

I'm only getting 160-170 miles per tank with E85. I was getting 200-220 before with my ej205 and a slightly larger turbo. I'm really stumped as to why.

Was the ej205 e85 or 93?

This was on was E85. I would hope people are getting more than 200-220 miles on a tank of gasoline.

[amroof]

I get about 180 to a tank on cor but i drive an fxt which has a bigger tank. I get around 12-14 mpg with city and highway driving mixed together. I commute 60 miles a day. lol

My car has a v9 jdm 6speed trans in it, which is the shorter 5 and 6th. makes for a hell of a highway monster :-)

I also run 1200cc injecotrs with an aeromotive 340 pump and an upgrade wastegate spring and 24psi. So gas goes fast.

But I get about 250+ on gas, 91 that is.

Hope that helps a little.

[WhiteBgeye02]

i can get 320 on 93 octane on a tank. 5mt ej207 v9
e85 i got like 240 and it included the tuning miles of 45ish out in the country. tuners dont tune for mpg and it takes a long time to make sure its done right and a egt gauge. you can guess its not getting really hot but until you record egt you never know how hot the exh is slowly getting over time. its not like a wot pull and after 20 sec its all done. 60 min at the same rpm with cruise control takes its toll if running really lean and putting tons of timing into it. thus making the heads really hot and deto will start then and knocking up the wazooo.
my best tank was 350 miles and put 13 gallons in. so about 27mpg. avcs tuning helps a lot too.

there are some ppl that can get on those flat highways at night w/ cruise control and burn a tank w/o touching the gas/brake and get 30/31 mpg out of the ej207 on a 5mt. a friend got 28mpg on his ej205 on a long trip we did in illinoiss. hills kill mpg and so does not using cruisecontrol or you brain when driving. keeping your foot on the gas when you see 1000' ahead it is a red light then engine brake, it wont burn fuel and will slowly bring you down to speed. hopefully not all the way down so you will still be rolling when you approach the intersection and can continue w/o having to go through all the gears up to the speed you choose.

if you want to get good mpg then buy a prius lol. jk but i fyou read up online of those guys getting 100plus mpg read on how they do it. its not fun bu tit all adds up.

my car of coarse goes really aggresive once load increases over 1.15 and its balls to the walls on the edge then!

Alright so finally got around to pulling my DTCs and I have only one, P0390. Now this appears to be the code for the drivers side AVCS solenoid if I'm correct?

I double checked my wiring and all seems good to go. Checked for voltage at the connector with the multimeter, the yellow wire seems to be seeing progressively increasing voltage as the car warms up[is this correct? What is peak voltage it should see?}, while the ground wire seems to have good continuity (1.8Ohm showing). SO I don't THINK it's a wiring issue...unless the voltage I'm seeing is wrong.

Pulled the oil supply line and it looked clear, no filter in the bolt and there was fresh oil in the AVCS unit.

I'm starting to think the Solenoid it's self is bad. Are the two sides interchangeable? If so I'll likely just swap the two solenoids to see if the code changes sides.

Any input would be appreciated.

They can be swapped no problem.

Scratch all that, I'm an idiot. On a 3rd look I noticed I had 1 wire on the ecu connector in the wrong pin. Swapped it and BAM no more DTC. Officially DTC free

[stlnation]

can you tell me which motor this is? its being listed as a v8 but i checked the bonanza but it showed 2 options v9 or v9 spec c

[Vlad]

I'll check the part number later today and I'll post this.
Note the ECU part number from the list, however and ask them to supply you the part number of what ECU they intend to send with this engine.

[25rsti]

Without looking at my sheet it's probably a v8 non spec c.

[mike280]

That oil cooler looks like spec c to me.

No it's not, that is an aftermarket sandwich plate below the stock oil-water cooler. The Spec-C does not have the oil-water cooler at all and its oil cooler goes directly into the filter base, no sandwich plate.

V8 or v9 it does not really matter in a practical sense as they are so similar, it is not a spec-C

Luke's correct. The Spec-C cooler looks like this (the one on the motor, the one on the floor is the RA-R STi unit):

[K1WRC]

Weird, on the list the DW7CR can either be a regular STI or a Spec-C. Get them to send info on the turbo and ecu, then you'll know for sure what car it came out of.

[Computersare8ad]

Intercooler is a V9.. can tell from the split at the top vs a bar all the way across.

[D-Rodman]

Label code is for a MY05 ver 9, with that oil cooler it would be a non spec c, I had that same sandwich on my ver 8 non spec c.
Make sure you don't end up with a ver 9 immobilizer ecu.
