Remaps and mystery ecu

[nobananas]

I was a bit bored today, bored as in got loads to do but not having the energy or inclination to do any of it !. Went out and started the still unfinished R so I could plug in a tyre inflator and re-inflate the front tyre that goes flat every week !. The other T5 was just sitting there and I decided to have a play around. The ecu in my T5 was sold to me many years ago as a Rica 304 and despite it being unmarked I've never doubted it as it goes well with it in and boosts higher then the standard ecu. The R has a Rica labelled ecu in it so I popped that out and swapped it into the old T5. Gave her a blat and it feels much the same. Now we come to the 'mystery' ecu found in the boot of the R. The previous owner told me it may be remapped but he wasn't sure, it again is unlabelled apart from having a 'N' or 'Z' scratched into it (depends which way you look at it). I popped it in and gave it a blat expecting nothing but a standard map, I was wrong !. With this ecu in it boosts much higher in every gear. With the other two ecu's I get a peak spike of around 1.1 bar, then it seems to tail off and settle around 0.8, with the mystery ecu it boosts closer to 1.2 bar and just stays there (my boost gauge may not be terribly accurate though I admit !). Anyone know how I can find out what or where the maps come from ?. It may just be that the other two are actually Rica 280's and the mystery one is a 302 or similar, I've taken it out at the moment until I can find out if it's fueling properly with it in.

You can read the chip quite easily these days.....some tuners put their names in the binary

How do I go about it Dave ?

You'll need motronic suite here, a K-Line cable like this, and some info from here and here (bit of a read i'm afraid)

As long as it is a Motronic 4.3 ecu. Motronic 4.4 ecus can't be read fully.

And not sure if yours has the obd port inside the car, if not you'll need to hook it up manually.

Just stumbled upon this thread tonight, thanks for the excellent links, I shall now go forth and expand my ecu knowlege, it will be a long while before I imagine that I will understand it enough the make an improvement, but I'll give it a go

Well if you got any questions just ask away Motronic is quite simple to tune, maps are easy to read.

LOL, Norton is just useless TBH, terrible protection and performance sapping :/
I have scanned it with Avira and Avast and both are fine with it. Here is a link to another server which hosts motronic suite, see if norton likes that one.

The link to motronic suite is on Mercuric's hosted site (he's the guy on Volvospeed who has totally ripped apart Motronic 4.4 and opened it up to some awesome mods (fast data logging, open loop and better boost control, alternative boost/ignition/fuel map selection using the throttle!)) The original server motronic suite was hosted on was shut down as the guy abandoned the project so its down to the die hard fans to keep it going.

I have used Norton products for 15yrs and they have kept me well safe!

As this link may have originated from the USA then that is good enough for me as Norton is cleverer than i am......

Very true.
