The Tuning Thread- EJ Motor

[Lance]

Check the compatibility. It is based of the Group N map so it's usually only workable on JDM EJ205/7 16 bit ECU's. There is an extensive thread on romraider.com

Pretty sure it would have more details on compatibility there.

Whats your rom ID?

It's a bit tricky finding info because my Wrx is an 04 sdm, which means it doesn't have avcs but not sure if it flashes with the 02 method or the 03 method, I believe it's similar in mechanical parts to the 02 Wrx but the ecu is 03-04. But then again I can be wrong and I'm not sure. Any sdm owners can lend some info here ?

[castortroy]

02 WRX is the flash method for the carberry rom. If you can read the rom ID using this flash method you are in luck, dont worry about the heads at this point in time

It's been a while since I posted.

I just finished some small changes to my setup. I haven't had the time to dial in the tune yet though.

My tuner was able to finish idle and cruising conditions but we haven't touched the WOT yet. It's running wastegate boost with dialled back timing until I get around to it.

Looking real good bro.

[nervewrecker]

If you hear how it sounding.

[A.W.O.L]

Still lil new to this ej20
But i running lean at WOT
Last yr i dyno to get a base run an got 186whp an 189tq
Last week i did 168whp an 172tq
Any particular areas to pay attention to get bk the lost horses.?
The car stock btw..07 legacy

[Lance]

How lean are you running at wot?

If all of a sudden you're running lean then you need to check for mechanical issues.

E.g. A post MAF-pre turbo leak could be causing that type of lean WOT condition.

Either way, you should back off the throttle until you get back your AFR in a safe-er range.

[A.W.O.L]

I dont really run hard jus on a lil clear street i open up...

[racedriverpro]

Hmmm... what kinda work u had done?

[A.W.O.L]

None...i jus installed a grimmspeed aos kit
A meth kit jus installed not turned on or tuned yet
Spoke wit the tuner he said strt wit cleaning the MAF check in tank filter then regulator

Yea man I hear it a while now....lol

Hmmm u should start with a learning view. If u like I can take a look for u. Learning view and we can start from there....free of course.

[racedriverpro]

Btw I have a like new filter.

I had the car tuned an serviced an it runs great so far
Thanks for offering to help...

Np. Glad u got through. Keep an eye on it tho. Always good to check back when the ecu settles wrt to learned values.

[A.W.O.L]

Yea it was lil jumpy at 1st but it settled on 14.9 on idle an 10.8/10.9 at WOT

How fuel trims looking?

[boosted_wrx]

Oh great Subaru gurus I stand before you, I would like some help, so I just finished up my Wrx, now everything is put together, using injector decaps I was a bit skeptical about it starting but it just so happened it did start before it got a tube, it started it and as expected it idled rough but it jus so happened as I was pulling out of the yard I realized my gearbox died along with my exedy clutch, long story short fixed that and new clutch and box in, going to start the car, to take it up to the tuner, just so happens the car cranks, turns over and sounds like it's igniting on only 2 cylinders, called the tuner, he flashed a base map for the injectors, still no start less gassy smell, flashed a speed density map on still no start, before this plugs were wet so I know I'm getting fuel. When the car started the first time with broken box and clutch, car idled and started most importantly, won't pass 4K rpm tho. Gonna swap back injectors next week, see if it would start, but stuck between cam and crank sensor or coilpacks. Considering the car started before, I don't think the injectors are the major keep back from starting, but between the sensors and the coilpacks or any other suggestions why it would not start, any help would be appreciated.

reset ecu and try again. Coolant temp sensor probable. I think it's over fuelling.

Checked coolant temp sensor before, tuner flashed a map to work with the injectors to see if it would start, nothing ...... Pulled my map and scaled the injectors, still didn't start, leaned it out a bit still didn't start only cranking, it started before on the injectors without the tune. Could an injector be dribbling ?

[racedriverpro]

^ possible. But should still start. Checked all fuses? Fuel Pump especially unless u can hear the pump running. Iacv could be responsible too.

[air wick]

Get a compression test done, over fueling and no spark could have caused bore wash.

Getting fuel pressure, reading on fpr gauge..... Will have to do a compression test

[boosted_wrx]

Changed crank sensor and went back to stock Wrx 440cc injectors, car still won't start ........ Plugs wet still

[Aaron 2NR]

i had a similar problem over a year ago...

[Ted_v2]

Wet plugs won't fire. Let them air out before trying to restart

[racedriverpro]

Injector seals or faulty injector(s)

Did you do a compression test?
