Rev D Reflash - who has done it?

Glen coz its close. Dtech would be first choice but cant afford the risk of breaking it down there and trailering down and leaving it for week etc logistics just dont work.

Just leave it at my place, it'll be sweet bowl

[Marky]

Work in progress, and ignore the numbers - I have no idea if the ratios / weights etc are right and it is a virtual dyno afterall, I could have drawn these in Paint haha (it should be right +/- a few HP to be fair based on airflow and other cars)

Before - stock ECU tune

Now - this is a quick log on the way to and from work, backed off early on the blue one for one of those pesky roundabouts hence the early peak and fall. Red run was car up to temp in the morning but having seen no boost - genuinely do feel it perk up after getting woken up once or twice. Blue run shows this as it was just after the motorway.

Suffice to say that other than the change in exhaust note and mild bump of torque, you can't pick it as being a sequential twin anymore

[McDoof]

Nice work. Now I really feel I want a TT again. When are you in AKL again? I think a joy ride is in order

[Marky]

Got the graph to show boost plot now too, neat. Also figured out how to input my cars' weight and gear ratios so it *should* be more or less accurate, ish, as much as a virtual one can be

On the lower graph the dotty line is manifold pressure, the solid line is the output from the differential sensor

What's a VOD?

[McDoof]

That's bloody impressive.

[lachlan]

How do u read that differential pressure line ?/how do u interpret it ?and what way do u have it displayed .

Shoyld we read it as a 5v scale on the y axis ?

[Marky]

Oh, yes, exactly that. Well, 0-2v

Bascially it goes big difference - then switchover - then no difference (equal pressures). It reads between 0.6 and 2.0v but for whatever reason shows up with rando numbers on the graph

Does show how quick it jumps from single to twin. Power curve however doesn't notice it and boost dips maybe 3psi tops? Can't feel it on the road

@Andy_Mac @Marky So i have a Tactrix and had a play around last night, can datalog with Romraider ok but cant get Ecuflash to open ECU to backup the existing Rom before having a play. i notice you had trouble with locating the correct definitions and at some point managed to get in but you never mentioned how haha. any insight is appreciated

 

I have connected the green connectors together which puts it into test mode but should i not do that and bridge the white one like below?

@kwi_fozze

Was it green and black connectors?

[telemekas]

Green connectors and the 4 plug White block which requires 2 bridges.

Shouldn't have any issues pulling the stock ROM even without the correct def file. See if kwi_fozze can give you a hand.

 

Marky got the correct def from @GorGasmSpecB from memory, as his wasn't in the standard def release.

 

Post up what the ECUID and CALID come up in romraider

[A_J_T]

@Andy_Mac  CAL ID: A4SD900B ECU ID: 1B04490605

 

 

this is the error i get in EcuFlash, I have it in test mode and the 4 pin plug jumpered.

 

 

i've tried all relevant Subaru definitions listed, that being said i updated the subaru definitions into the metadata folder as it suggest but it doesnt list them in the vehicles.

 

I'm aware its probably me missing something basic so no panic i'll keep readying away at all the stuff i should know before actually getting my fingers on editable junk

[Andy_Mac]

You tried changing the vehicle/ecu type?

 

You don't need a def file to pull the original ROM but you do need to have the vehicle type selected correctly or it won't understand jack all and probably give the error you're getting. That was the big trip up I had when first trying to flash ROM's

[A_J_T]

yea i have tried each one. only the 2001-2005 wrx one seems remotely close

[Andy_Mac]

Have you swapped ECU's or still using the stock one?

Romraider seems to think that ECU should be in an 01/02 STI

 

[A_J_T]

Yea makes sense, stock ECU but its single turbo conversion tuned by DTech. It is possible its locked but will look into it further when i get the time

[Andy_Mac]

DTech wouldn't lock a stock ECU. Would have thought one of the vehicle types should work regardless. Dunno how they do it but you'd typically just get a stock STI ROM thats from the same generation and flash that to the ECU. Maybe ask Tony to check whether Dave still knows if they used ECUFlash or ECUEdit to tune it. 

 

Hard to say without seeing it. Try reinstalling and/or running in admin mode aswell

Dont be a tight arse buy a link @A_J_T

I will when i have a setup that requires it haha, currently just trying to have a play with increasing launch control rev limit as its a little low to hop off the line and a little data logging 

[Kiwi_Fozze]

Non usdm (wrx02) definition.

 

Green plugs together. Jumper in place.

 

Make sure you are plugged in to a usb2.0 port, it doesnt work,in a 3.0

[Kiwi_Fozze]

A4sd900b is a common definition as well, i've tjnkered with those roms a bit.

 

So that helps narrow it down

 

Its a connection issue, either laptop to car or within the car itself. Process of elimination, double check jumper connection, green plug connection and then a different usb2.0 port

Yea thats basically the conclusion i came to. Logging works fine so pretty sure i didn't buy a dud Tactrix. have tried a couple USB cables but have not double checked my jumpers and connectors under the dash. Also apparently there is a knack to getting into these. There is a very narrow window between the ECU booting and then going into Test mode that ECUFlash needs to jump into. Will have another play tonight. Cheers guys for all the help.

[Kiwi_Fozze]

Bootload

Bootload

Bootload (flick key on)

Bootload

Then it should connect.

 

But, yeah check the connections under the dash to make 100% sure its right.

 

And triple check that you arent plugged into a usb3.0 port (that one screwed me up for a while)

[A_J_T]

Ok im in. Was just me being a muppet as i suspected, in my rush last night i didnt join the 4 pin flash connectors properly. got under the dash again and realized the wire id used to jumper the 4 pin flash block were not seated properly.

Mean, its nearly always something small
