for starters, before i go into any more detail, is it even possible to communicate with the ecu on this model/age of car with a tactrix...iv looked on rom raider etc and it seems to be a bit hit and miss?

anybody have any experience?

cheers

yep

d.kenny

good news then

might do a bit of a project

list of tools at my disposel:-

tactrix 1.3
innovative wideband with exhaust clamp i made
all important laptop
bodywise rough 2001 totally standard wrx

think i need a different version of rom raider or ecu flash as i have the older cable

im sure i will soon find out when i go about plugging it in to the car

any steps i should take to read the flash etc?

i had a mess about with rom raider before using a few maps i was emailed and used the defs from romraider and it all seems a lot more user friendly than win-ols etc that i have spoken about before!

in fact here is the old thread:-

thats where i got upto

As long as the drivers install ok , the current versions sghould work ok I believe, bludgod has a 1.3 and I dont think he had to do anything special though should confirm that with him as Im using an OP 2.0.

Where in the world are you? there may be someone local who can give a few hints or show you.

edit: just realised that I posted in that other link

you can download the latest version of romraider and ECUflash and you'll be good to go even with the 1.3 cable.

My car is the same as yours - use some wire to bridge the flash block and use another bit of wire with a switch on the end for the green test mode connectors.

If you need a hand getting your first few map tweaks done give me a shout happy to answer a few questions if I can

d.kenny

Yh cheers

Do you have any pictures of what pins to bridge

A switch is a good shout on the flash block...might even mount it in the dash for easier access!

d.kenny

bludgod do you have any pictures of what you have bridged and switched?

i thougfht the green test connectors were plugged in together and then a switcv on the flasgh block or do i have it wrong?

got the car the other day but not had time to play yetr

just want to get everything in order first

what is the first port of call?

ecuflash to copy my original file?

bludgod

iTrader: (3)

On mobile at the moment but short answer is the flash block stays jumped all the time and you put a switch on the green connectors effectively joining them when you want to upload or download a file. It doesn't need hooked up just for logging or driving.

Step one is to use romraider logger to grab a learning view image (show ltv button in the logger) then use ecuflash to download the rom from your car and post it up always good to have backups!

i should just stop being so lazy tbf

d.kenny

m sure that will make more sense once im plugged into the car

i takle it i need 3 programmes...which i have but probably need updating...these being

ecuflash...to read and write
romraider...to log
ecuedit...to...er...edit

is that right?

d.kenny

did prodrive do a map/rom that upped power on the wrx as an option?

anybody have or know of a place were i can get a rom to compare to my standard map?

brendy76

iTrader: (6)

Pmed you there matey.

d.kenny

reading through everything on rom raider...way to much info

think i need to sit down in the car and do some practical work instead of theory as im sure it will all make more sense

im thinking that after doing a few logs so i know how the logger works that id rather make tweeks and test and check afr and knock than i would keep checking logs etc etc

or have i got it wrong?

brendy76

iTrader: (6)

Lots of logging, minor changes, lots of logging... slowly slowly catchy monkey matey

Do you have Skype or anything? Easiest way will be a few minutes screen sharing to show you the ropes. It's easier looking at work in progress rather than looking at a blank canvas I think. PM me details if you want

d.kenny

yes i could skype!

prob best i try and do a few logs and get the car hooked up aswell first

from the romraider forum i think its more learning to interpret the logged data as opposed to tuning

then again the majority of the stuff i have read is just tweeking

i want to ramp the boost up and fuelling and advance to see what i can get out of it

i may be trying to run before i can walk here though

what have you managed to achieve with your cars and what mods?

bludgod

iTrader: (3)

no ramping just yet, get used to what you have and read read read

if your house wifi can reach your car parked outside your house then we could be in business. But if not I'm happy to show you the same on my car some time or skype for random questions if you have them.

The thing you can't value enough is the quality of data you have, without quality data to analyse then your already heading in the wrong direction.

If you have some free time give me a shout, I'd be happy to bend your ear on how to get a leg up on the whole thing.

d.kenny

that would be great

the wifi will reach yh

it will prob be over the weekend

il have to send you my details and then we can go from there!

Manford

Is the 2003 pro drive map the same? If so could I have a copy?

Will be following this thread closely as I'm thinking of doing the same.

'01 Bug WRX
VF24 Turbo
STI Pink injectors
3" Cobra turbo back non resonated system
Perrin turbo Intake
Green Panel Filter
Classic uppipe
few other little bits and pieces.
Havent had it on a dyno but my figures come out around the 310-320bhp and similar torque, I could press boost a little more, currently running 1.3bar and could up it to 1.45 or so and raise the taper towards redline. Wont be doing that until a new clutch arrives

bludgod

iTrader: (3)

oh are we playing top trumps

01 bug wrx (running '03 rom for better boost control)
TD05-(big)16g
STI Pinks
2.5" Afterburner Vortex non-resonated
Toyosport Turbo Intake
eBay mushroom filter
custom airbox setup
STI intercooler
3port solenoid
1.5 bar all day long
launch control/antilag/speed density when the mood takes me

Probably the same kind of power output as brendys bus - certainly has no problem passing an STI. I've also helped quite a few members on the Romraider open source forum and a bunch of guys remote mapped from all over the globe so I'm sure we can get your bug kicking some butt for you.

d.kenny

iv seen the hack for speed density and didnt know whether to actually go with this from a learning to tune perspective and its something that can be applied to a broader ranger of vehicles with aftermarket ecus

currently what iv got is completely standard but iv got a fair few bits off some of my classics spare

vf23
td05
air filters
exhausts
front mount etc

i only got the car though really to learn mapping on and see what i can do haha

d.kenny

i have not seen the one for anti lag though haha

d.kenny

how do you know what is safe boost to go to aswell? thats always puzzled me as people say what bnoost you can or cant run?

surely if your injectors can handle it and the boost keeps building you can just keep going for it within reason???

id like to see 1.5 bar of boost

do you have 1.5 bar peak or held lol?

will the td04 handle that?

d.kenny

how doe4s t4he 01 and 03 rom differ?

have you compared them?

sorry for all the posts and quesdtions ui keep picking extra bits up lol

bludgod

iTrader: (3)

see - this is why skype is useful because you can shoot me a question and I can shoot you an answer bak


OK so...
the "hack" for speed density is not a hack, look up "carberry rom" it's coming along rather nicely and now supports MAF mode too but you must remove the TGV valves from the manifold or the car won't run. The carberry rom is based around the groupN stuph hidden away in most of the cars. Also if your gonna play with antilag I would recommend you move the front O2 to the downpipe as they will die off rather quickly. Bonus for moving it to the downpipe is you can get a wide range from it when on boost as well - handy for the DIY tuner.

I would say go for the TD05 and the front mount and see how you get on, the TD series will take a fair amount of abuse before they snuff it compared to the VF's. I would also argue that the VF is a better turbo generally but if your wanting to tinker it will cost you more to replace.

"How much boost can i run" for this you need to read the compressor map for your turbo and look at the CFM and efficiency zone on the compressor map. Run too much boost and you'll be pushing so much hot air it will start to knock and lose power. Not enough air and you won't be making any power. The balance between the two is part science from the compressor map and part experience from looking at lots of cars and turbo configs. This is kinda the difference between a beginner, a hobbyist and a professional tuner the likes of Bob Rawle etc.

1.5 bar sounds great and all, but do you *need* 1.5 bar and is it making you power are different things. You might make just as much power at 1.3 or 1.4 bar if you keep the charge cooler with a massive intercooler, plus some quality fuel maybe a hit of meth and some muchly advanced timing.

as for "will a TD04 handle that" - is it capable of that much boost? quite certainly, will it last forever at that level? No sadly - but it will have a glorious death giving you everything it has for those 10 seconds or less.

If you physically compare the TD04 to a TD05 or a VF turbo you'll see quickly that the turbo is much much smaller. It's small size gives it a quicker spool up than its bigger cousins but the price for that is there is no top end of which to speak of. Past around 5500rpm there just isn't anything really to give. No big deal as you just rev on to 6k and then knock it up a gear landing you back in the (relatively) monstrous torque zone.


Ready for round two of questions when you are

d.kenny

lol

im gonna leave it in standad guise for the time being

i want to get to grips with the lap top side of things before i start bolting different stuff on so i can see what tweeks i have to make with each bolt on mod without getting myself in a pickle

i really need to lesarn how to do the logging and that first though

im gonna be with the car tomorrow i think now in the day so will be taking my laptop with me and tactrix cable and be doing a bit of youtubing and if you are available il do some skype or facetiming lol

bludgod

iTrader: (3)

aye a bit off skype is no bother, you gotta pay extra for the video calls though big boy :P

d.kenny

lol

i do sort of feel rude/lazy getting help but 5 mins on skype is probably like 3 weeks worth of nights solid reading and will probably be lots less complicated than originally thought

and you offered haha so its rude not to

i think its learning the software more than anything as i think i know what i want to tell the engine to do but its just learning how to make it do it

d.kenny

so iv just plugged the car in and read the flash no problem and also managed to open up in romraider editor

according to romraider my ecu definition is A4SE700D

iv got the eml light on on the car to so how can i with the tools i have here identify the cause of the light and reset it?

i could use my scanner but id rather try and use my laptop and do everything in one!
