remap 7202 ecu

[Miss_laatjuh]

hello ,
i am looking for somebody that can change my 7202 ecu from m/t to a/t ....and also can remap it for me ,,i have a vr2 ,a upgrated intercooler ,3 inch exhoust ,(soon) 2x2,5 inch to 3 inch downpipe ,2.55lh fuelpump , let me know what you can do for me and what price is it ,

regards peter

hi there,
it will help if you state what country you are in and where in that country you are.
you profile says 'other'

remapping engine perameteres by post is never a good thing.

Although post isn't the best option, there's no one over here (Netherlands) experienced with these ECU's. And driving over to the UK would be an option, (the best option) but if it's a matter of 'educated guessing' based on experience then trying a spare ECU set up via post isn't such a bad idea. If it runs like sh*t, he can change back to the stock ECU. As a matter of fact, there's no need to post anything if it's just the ROM/BIN/XML files itself that would be modified. I'm pretty sure they don't have an Openport 2.0 cable, nor EVOscan / ECUflash software though, although that might be the most ideal combination:

Someone who'd be willing to tweak the 7207 software, email it, flash it, test it, fine tune the software further, etc. All needed would be for them to invest in an OpenPort 2.0 cable (179 USD via http://www.tactrix.com) plus the fee for someone willing to alter the ROM/BIN/XML for the 7207 ECU.

My 2 cents (and interested in this setup too by the way, having a similar VR2, although a manual).

I understand what you saying there mark and it can be done that way, but i would have thought you would be needing the following to make a poper job of it with a 7202 ecu.

open port 2.0 cable £130
evoscan $25US
AFR gauge wideband loggable with evoscan. £140
ecuflash £free
Boost pressure loggable. £25 plus wiring to ecu.

watch/read understand the following infiormation.

http://www.clubvr4.com/forum/showthread.php?67698-Basic-Introduction-to-ECUflash-rom-tuning-and-Evoscan-logging&highlight=basic+ecuflash

you will be 90% of the way there. the rest is playing with it.

then you would have to do an agreed set number/types of logs with evoscan, pass all the logs back to the tuner and then the tuner could attampt to make some small adjustments pass the a modified rom to you you flash it to your ecu, do the agreed set logs again and it all goes round and round.

It is not prefect, but the person wanting the tuning done is prepared to take the risk, and responsibility of potential damage then someone might take up the mantel of remote tuner.
there is enough info in the video to get you started and once you have experimented with you own car as i am doing at the moment then you could offer to help others in you part of the world, it all about gaining the confidence and experience.
well that is how i see it, how does that sound.

i understand , but i dont like playing with my car ,it takes a few years to make it what it is and work very hard for everything and im not gonna play whit that ! i realy apreciate all the info and help but i just dont want to do it by myself ,somebody from here do the same with his 7201 ecu ( the guy with the green vr2 from my country and he like it ) he give nutter john some info about his manegemend and it works perfect , someone gonna help me please ?

personally i think you would be taking more of a risk just getting a map flashed to you ecu with no testing and tweeking on your car.
i think the reason the 7201 would have been upgraded with no testing and tweeking was because when it was done you could not do anything else. you would have had to unsolder the rom chip and solder a new on e in with a new map. so no tweeking possible.
now you can remap the 7201 ecu via software and not by hardware.

i presume you have evoscan for knock monitoring, and AFR gauge and wideband, boost monitor, even if it is a just a boost gauge, so at least you can monitor what is going on with your car. after it gets remapped, if not you are taking a big risk.

but as you say it is completely up to you as it is your car and you have worked hard to get it that way. I hope your remapped rom keeps it that way.

Peter, just to make sure you completely understand: ECU mapping/flashing is basically uploading a new version of the software into the ECU. Compare it with an iPhone that started with iOS4 and by updating it, it now has iOS6 (maybe an Android acronym would have been better, but I don't know anything else but iPhone). Thanks to these updates, you get all kinds of new/changed functions. Same principle for ECU flashing/remapping/whatever it's named. Changing the ECU software-settings/details itself is where the experts are needed, but doing the 'update' is not very complicated if you have the ECU installed in the car plus a laptop, an OpenPort 2.0 cable, flash-software and the changed ECU-software files.

What is said in this thread thusfar is that there are basically 2 options, but for both options it would be best / you should need:

- a wideband lambda sensor with an AFR (air/fuel ratio) gauge for example from MTX (without you have no idea how lean/rich the car runs and at which rpm's, and which is also extremely important after a flash as you need the mix of fuel and air to STAY right otherwise you might get your engine blown up)

- at least a turbo boost gauge (without you have no idea what the current boost is and if the boost is actually changing after a flash)

- EVOscan software that runs on a laptop which logs basically anything that is happening in your engine/intake/exhaust/etc (if you have no idea what is happening now inside the engine, you will have no idea after a flash and if anything is important it is to know what the original 'baseline' figures were).

And then these are the options:

1. you send the ECU to someone who changes the ECU software-settings and flashes them for you on the ECU and send it back. Easy, simple, but if something needs to be changed, you need to send it back again, etcetera.

2. you buy an OpenPort Cable + EVOscan / flashing software and let someone (anywhere in the world) change the software-settings. Then you have the file send to you via email and upload the file via the OpenPort 2.0 cable & flashing software to the ECU. This is faster (no need to send the ECU back and forth) and more flexible (if something needs to be changed, it's again an email away and you're ready to try again. The changed ECU software flashing to the ECU is simple. I did it myself too. There is no way you will damage your car/engine/ECU with the flashing itself. It either works or it doesn't. If it doesn't, something isn't plugged in or set up correctly. These 7202 ECU's will work, I can help you with it if you want and if you have such an OpenPort cable. You can't really do the flashing itself 'wrong'.

But... NEITHER of the 2 options will give you any guarantee that the flashed ECU -->SETTINGS<-- will work perfectly with your car! If something goes 'BANG' it's not something that could have been avoided by sending the ECU to someone / doing the actual flash procedure yourself.

That is the reason why it's best to do such a remap with a specialist. Still, you can take the risk and do one of the 2 options and hope for the best.

that is a much better explanaintion of the posibilities.
