Default 4eat+ej207+vf30 tuners?

Hi all,

Iv'e been messing around with my ecu (carefully) and have pulled my rom (a/f gauge has just chort circuited ) and have been comparing it to to the 4eat us roms,

Iv'e noticed that my timimg is ALOT lower for example even under engine load .22 i'm only @ 18.32,.. where as the usdm is at 23.95 at 800rpm

btw a bit about my car...

4EAT (tip tronic/sport shift transmission, gears don't change untill I say so!)
stock V7 EJ207 +AVCS+STI TIMIC
VF30 (currenlty set as 18.5psi)
Straight through pipe +genome exhaust (no cats)
Apexi Power Intake
Walbro 255 pump.
Stock 565 injectors + NGK7 plugs.
Runs daily on BP Ultimate 98RON

Basically what I'm asking for is if anyone is interested or has some free time, are they willing to check out my map and see any areas where there could be improvements made?

Or reccomendations for a a reputable tuner? theres a large evo/skyline/rota user base over here and a alot of the tuners arn't too dearing with my 4eat lol...

I assume from your profile, your vehicle is a 2001?

I just checked the stock 2002 WRX AT rom and at .22 g/s timing is only 10.94 at 800 rpm.

Feel free to PM me your email and rom.

A stock 2008 WRX (2.5 motor) AT rom has timing at idle 20.08.

Do you know why I might have a 'base timing A' & a 'base timing B' map? other roms all have just the one timing map?

Is your WRX Europe, Japan, Australia?

I just took a peek at a 2001 Europe WRX rom and it only has one base timing table. I also see that base timing is different for Europe; idle is 19.02.

I have the 03 JDM V8 STI motor with AVCS and the twin scroll VF37, i have heard that the JDM motors are tuned to run on US gas (93 oct) and that they will knock and could cause catastrophic failure eventually. I did a couple runs and logged them, and as soon as i start boosting in 3rd, it is definitely knocking. Are you aware of anywhere i can find a basic tune for this motor on US gas, or do i need to just pull my timing?

anyone who says these motors run well on US 93 deserves some good spanking, get it tuned before it goes kaboom


to the OP, you are comparing a table to a tomato.
US 4EAT came only with 205 motors that are much more simple and have less power, I don't want to get into that now. They run smaller turbos, so it gives room for more timing with less knock. However I don't understand those numbers at load you are reffering to

now, I assume you have some JDM wagon with a sportshift, because if you have a stock 4EAT and you swapped in that motor - your tranny will go boom.

state your location, I might be able to guide you one way or another

I know this post is quite old, but just curious as to why you said the tranny with go boom? Just because of the extra rpm to redline or...? Not attacking or anything, I'm curious to know for my own set-up.

the 4eat will hold the tq just fine on the vf30. If the OP plans to do high stall launches, then it will die.

Since when? The major issue with the 4eat IME is they shift around 6500 rpm. Kinda useless having a motor that can rev to 8200 and a tranny that shifts at 6500.

On the tach, eyeballing it, it shifts at around 6800 for me, but the logs consistently show 6500-6600.

The more power you have the higher it will shift too. Commanded shift rpm is probably close to 6100 rpm. The faster your rpms climb the higher the rpm when it actually shifts. This is not a huge number but can be shown in higher hp cars vs stock.

Is that leaving it in 3 or D or manually shifting it?

3 or D, they have the same shift point on my car. Manually there is a solid couple second lag that is kind of hand to match correctly.

Can you explain what you mean by this? I am doing an 04/05 ej207 v8 swap into my 4eat 04wrx now. We cannot get the car to shift properly (hi rev between each). Doing the process the tranny did die actually. Is the 4eat not capable of handling the power of the ej207 or is there something else to know?

How can we get the 4eat to play nice with the ej207?

ive tuned many automatics, I actually have owned many what exactly happened? If your tuner uses improper. Scaling it can reak havoc on the pressure ramp up with the transmission. If you would like you can Pm me the rom or ask any questions - I'd be more than happy to answer.

IME the transmissions will not shift much above 7000 even on the 05 WRXs, which many times are slightly adjustable.
