help interpreting data
hello,
I have some records out of my car, they were recorded with tts datamaster 4.0.0

application specific file http://www.fileshare.ro/4172137204.5
or excel file http://www.fileshare.ro/4175636528.05

I didn't look at your data but if this is for a '91.
Their is nothing too special about the injector circuit for this year model all the injectors on each bank should fire at the same time because they are essentually wired in parallel. If 5 & 7 are not firing and 1 & 3 are then you need to look at the wire harness where the 4 wires break out for the 5 & 7 injector plugs or you have an issue with the injectors at those locations.
I'd unplug the injector connectors for 5 & 7 and test them to see if the injector pulse voltage is measurable at the connector.
