OE ECU reverse eng and upgrade pt1

Hi Martin,
PM me at tommy.decock@telenet.be
I got lots of items for you as I did in the past (some 5years ago) what you are doing now.
Also some info you published is wrong.
i.e. The R25T ph2 has two maps (fuel and ignition) of 9 by 13.
I got also some prototype ecu's with the the real ic numbers on them instead of the S100.... numbers.
So PM me. I can help you. Then you can (re)write the info of it on this forum.
Gtrz,
Tommy

This has already been done.

I have used later 25 2.8 and Espace 2.8 V6 ecus on the V6 turbo, using a Fastchip replacement re programmable Fenix chip. This comes with software and programming lead which plugs into the diagnostic port and allows you to reprogram (as many times as you like) the fuel and ignition tables in an easy to read format, not in hex form.

You can also use the internal lambda system from the ecu and a 5v throttle pot instead of the switched type.

It can change the rev limit, remove boost limit and use any map sensor etc.

I tested this on my own car, but it was crap and cumbersome, hence the swap to standalone management.

MAN ALIVE!!

:lol: MAN ALIVE!!

Good News then

What are you actually trying to do?. The problem with the PH1 ecus and why GTA's never make good power is due to the way the air temp sensors cut retard the ignition over quite a low inlet temp, and the coolant temp circuits are very tempermental (ive had numourous ecus that never read the correct sensor voltage), and the knock sensing is also over sensitive.

You might be able to change the maps, but not these external trims.

The PH2 ecu plugs straight into a GTA loom and runs the car fine, also there are a few Rolling Roads in the UK that can remap these ecus fine as they use the same architecture as the Clios, R19's etc..
