Well, the car is a DD and an occasionnal track car. But before everything, it's a DD.

Just your feedback on this here... the tuner came last week ( car runs like a champ btw, I think he did a great job ) and scaled down the injector flow rating instead of scaling the MAF for the 70 mm APS intake. First time I heard of that. Besides, it's all chinese to me. ( no offence here lol )

Every done that clark ?

WTF? Get your money back. You just got licked man. Why do you guys mess around with fly by night parking lot tuners?

I took references, don't worry. I've been in the business long enough. When a name comes around ( well, just like yours ) usually it's a good sign. I've seen his work before, and the guy has hundreds ( thousands ? ) done before mine. I trust his competance just like I would trust yours. He's coming back for the 725's. I'll inquire about that.

He did mention two ways of doing things. I guess it's the easier way. There's no point in killing the guy for a result that's there.

Its your car man. But there is not two ways of tuning injectors and a 70mm intake. Only one. Sorry but its not possible to tune every load calculation by changing a monolithic setting.

very true. i just did the bigger intake and larger injectors all at once. by changing the scaling of the injectors you may get it close but the intake will flow much differently through its design than a stock maf housing. air is kinda like a river. its considered a fluid even though its nearly invisible. more can flow around turns on the outside than the inside and the maf needs to be scaled for that intake. the only time i changed injector scaling was to go e85. i just knocked the size of the inject scaling down 28ish% and worked off that. the maf then had to be slightly adjusted again to compensate for the changed in injector flow at that given rate and change of fuel.......

idk if its worth it for you but i think you might want to invest some time in understanding the basic tune to get the car on the road. no need to worry about timing maps. avcs maps, or all that jazz but how the general set of systems work together. then if something goes wrong you have a better idea of what it might be.

so i pulled a learning view this morning and have no codes but my cel is flashing very fast. the only codes i disabled in the ecu were the rear o2 sensor and the evap system which i deleted. its got no memorized or temp codes. no knock. the afr's are like 1-6% off but i need to scale the maf in a bit better today/tomorrow.

the other thing i noticed is the iam is zero.... my initial starting point is 12. after driving 20 miles it down to zero. is that flashing cel knock? wouldnt it show up on the large table somewere and not be zero's everywere?

I thought that a flashing cel was knock...

I once forgot to undo the green connectors once... well.. not exactly. I had a toggle switch connected and flipped it with my foot. I took that toggle switch out that day.

no green connectors were not together.

i did read that iam dropping is from knock as well and the car doesnt have to do fine learning knock correction.... it makes it own decisions i guess

Yep thats it then. Unplug it. The usdm harness is diff and he intake temp isnt supposed to connected. I had the same flashing cell issue. Shld go away then.

Flashing cell without engine running means the ecu is in error state. Did you read my post to you about this?

If the flashing cell is when the engine is running, Then one cyl is not firing.

Unplugged coil pack
Bad or damaged plug.
Low compression
Injector unplugged

With the IAM at 0 you had SEVERE knock so a damaged plug or cyl would be likely.

If he's using an 03 harness in his swap then he should unplug the IAT sensor under the throttle body . There's several posts about this doesn't mean his engine is bad yet , if it continues then you can look into clarks post. The main thing is its doing it while the car is off but in the on position.

I posted this last week. I guess he missed it.

You will get those codes if the maf is unplugged. Make sure its plugged in and seated. Also. If your v7 has an intake temp sensor under the manifold, unplug it. Your 05wrx is not wired for it. The last thing you need to make sure of is that you do not have your Blow by connector installed or shorted out. Some Turbo inlets came with a shorting plug for the blow by connector as there was no place for the sensor. The JDM ecu does not use this sensor.

you want me to unplug the iat sensor only when the car is off but in the on position?

its a 05 wrx. complete v8 long block with harness and inlet and everything

maybe ill take an hour and put in the plugs i used in my last engien for 2k miles. will ngk bkr7eix work?

Those are the plugs clark suggests, I used them they work great. As far as the IAT sensor , I was just saying the flashing check engine light if it keeps flashing even when the car is turned off but in the on position on the ignition is usually a strong sign its the IAT sensor plug under the throttle body causing the cel also the cel has no code when you check it. Usually because the usdm harness uses the IAT in the maf sensor where as the JDM uses the throttle body IAT for temp and automatic intercooler sprayer.

You can run your IAT wires from the sensor near the MAF to the one in the throttle body , much better for readings and tuning I'm told.

All this info I've read from vlad and other posts with similar problems. If the cel continues after the IAT throttle body unplug I would read into clarks post on the flashing cel.

Listen to this guy. The flashing cel was nightmare for me. Impossible to get info. But i found a post from DS1 buried inside a thread and figured it out. Im almost certain this simple thing will fix ur issue

If maf based tuning is used. DO not rewire the intake temp sensor to the intake manifold sensor. Leave it on the MAF sensor itself.
