Other ( non boosted Renault ) XR25 PC DIAG on AC DELCO Injection : Clio / R19 / Express

Hi all,

I've recently installel XR25PC software and had very hard times to get the cable working.
I'm working on two cars :
1 - Clio 1 phase 2 , engine 1.4L E7J-710, Bosch Injection (sheet 28 / 62500 bps)
2 - Clio 1 phase 2 , engine 1.4L E7J-716, AC DELCO Injection (sheet 22 / 10400 bps)

The problem was that I've fisrt tried on the AC DELCO equiped car (had something to check about the idle rpm) and believed it was a cable problem because it never worked. Till the day I decided to try on the other car and it woked at first time !!
So I've managed to correctly connect to the Bosch Injection but not to the AC DELCO. This one has special behaviour :
First, when I select the sheet n° 22 and switch igition on, it reads one frame and goes automatically to sheet n°3 wich is 62500bps !!!

When I try to check the "unlock" checkbox to force sheet 22, it gives an error when receiving the 26th byte of the frame that looks like this (see attached file) :

ACDELCO.webp

Does anyone have experience on this type of frame ? I mean the AC DELCO one / sheet number 22 ?
If anyone has informations about the frame I can try to read it myself on the serial port and code some software that does the job for this type of injection.

I've also sent this message to the master (@Chet T16) but thought it would be better than anyone has acces to the discussion.

Best regards and happy new year !
