There is no way to set injection timing on a 94/95 electronic IP other than the scan tools mentioned above.

If you own a 94/95 6.5 you really should invest in the software/cable that goes with GMTD ScanTech pro version.

$160 for GMTD ScanTech
$60 for the cable

There is a way to make the cable for about $10 also but is a little crude.

Since the vendor is not a site sponsor I can't post the link but PM me if you want the info.

The ECM has to learn where the IP physically is situated at to control timing and to even report the timing to a scan tool.

The problem arises when the IP is moved or replaced-there will be a timing value in the computer that it thinks is correct and no matter where the IP's actual location is in relation to the crank the ECM won't know a change has been made unless it is commanded to relearn the new IP location-ONLY the above mentioned scan tools have the ability to force that relearn on a 94/95 6.5 electronic IP engine.
