stock ecu remap for 2.0 8v

[jayjay]

so.... in the final incarnation of my motor, i'm running with EFI from a seat ibiza 2.0 gti.

except i cant seem to find anyone who does custom maps flash loaded onto the stock ecu. I'm not really after a generic piggy back chip because i have a couple of custom specifcations I want.

any body have any leads as to where and who?

I'm quite willing to ship an ecu overseas..

cheers

The ECU needs to have chip put in it. They are socketed so you can do it yourself.
I bought a 'tuned' chip off ebay. The car goes a bit better, certainly revs at the top end more.

Not sure you'll find one custom written but you may get lucky?

I was under the impression from when i talked to techtonics that maps could be flash loaded through the obd port, or a chip could be installed... i should read more into it..

[evorobin]

Dude same as digi just repace the chip for MUCH wider powerband rather than big midrange and no top end.

Ive been discussing this with Seb in relation to my VR6 . He isnt happy with the ignition timing around 1500-3000rpm . Too much advance .

There is a windows based tuning program thats available . You can write the software onto an encrypter then solder in a socket and swap chips over when you modify them . There are writeable chips available but they arent cheap . Your also gonna need a dyno do to it properly . Sebs looking at doing this soon cause no one else does custom tuning on older cars here . Whats your ecu number I can pass this info on and give you some options .

Thanks courtney, I've read a bit into this also about the downloadable windows program.

I'd need someone who knew the mapping interface... ( might know someone ) and maybe a dyno... hehe. i know exactly how you feel, all the money here is in new chip tuning and stock ecu mod art is dying out.

i know sofarasmuch as the chip in my ecu isn't soldered in but socketed. i'd also need things like a micro soldering iron. this 6500rpm limiter is soooo annoying.

btw for your vr6, try techtonics tuning. i've been talking with collin there, and he's an absolute nutter ( in a good way ). they do stock chip tuning pretty cheap and they can all be custom tuned to motor specification.

any body heard of a place who does this in South Australia?

why not just go standalone ecu>>??? then you can atleast tune it when ever???

the odd 3k for the ECU + tuning I'm guessing...

[Jarred]

microtech will set you back half of that, tuned as well.

(although depends how much you tune yourself, & get tuned etc, but still roughly half of the 3K)

[jayjay]

well standalone has its pros and cons. whilst i'd roughly know how to set it up, tuning is continously required. I have a friend with a 20vt on autronic who had a dyno tune and it was horrible. it's lumpy and the afr is rubbish and the motor is stock....

also, for my application, all of the parts are easily servicable and attainable. i'd do megasquirt if i had the inclination but i like vw reliability.

oh jar-rad, if you can find me someone who wants to supply, fit and tune my car to its current state of reliability, i'd probably do it tomorrow. ( dont mean to be a cocck )

[Golf Loon]

I had microtech on the VR6 Ibiza and it was never right, rubbish cold start and limited mapping. I had it on the dyno 3 times and it was always far from perfect.

its a far cry from VW reliability and smoothness.

I reckon buy a 20quid chip jay jay and see if that helps.

[DUB 12V]

guess you have never had a good tuner then i know you guys dont like him lol but dub 20v mk4 gti on full haltech ecu is like driving a std car,, tuned by hitman injection tuning,

jay if you get a chip and its still not correct for you car you are still up the creek with no paddle....

haltech for the alot of cars now is like 1500.00 fitted,

its only a mk2 non turbo not hard to get it to run right, not like it will over boost like a turbo and and shut the ecu off..


just my 2c but i dont know ****.....

[jayjay]

there's actually an extremely large problem with not getting it running right... that being lots of bent valves.

being a mk2 and non turbo has nothing to do with it....

if i had been convinced of the merits of standalone for this car, it would already be installed... the motor's only been out what like? 6 months...



i appreciate the ideas guys but i'm still curious as to whether someone in our neck of the woods does this.. useful for future reference too

how will that change if you tune is crap with the std ecu??? still can have bent valves if that tune is wrong...????

maybe you should have just gone 16v still prob be faster than the old 8v,

my mate had a 8v all worked ported/polished big cam 1.9l brian gti imports bottom end, on micro tech, kept up with a vr6 no probs, but still not a fast car.

hope you work it out soon should be a ruff rig. good luck...

Well I' hope this doesn't p#$% anyone off as I somehow managed to do on the 'other' forum but we are doing some older stuff, depending on what hardware is available of course. You need an eprom programmer, proper soldering gear, an eraser (depending), spare eprom and if its not already fitted an IC socket to allow future changes. You then need software to edit the various maps within the binary file so your editing software needs to be able to do that for that specific ECU. Some of the older stuff seems to fall of the radar a bit.
Depending on the vintage of the vehicles ECU the software also has to have the ability to calculate checksums which are then included in the new modified binary file.
Alternatively you may already have a tuned file from a rom provider ready to go in any case you then 'burn' this data to a new chip (hopefully you can find one) and insert it into the socket
...And then you get to the dyno. Its even easier of course if you have the whole chip ready to go

I'm doing a 98 volvo of all things shortly

ps if the Car with the Autronic is not running well the guys that did it really had no idea.
