Bob is there a Scanmaster for a...

[WS6]

1992 vette with the LT1?

One of my racing buddies has a 92 vette with the LT1 and a procharger and he would desperately like a way to see any KR or have some sort of knock gauge.

Do you have a scanmaster for that year LT1??

Or any suggestions?

that ECM has a chip, and is speed density, right?

So, there is a 2bar chip for it? Or are they handling the fueling with a FMU or something?

Anyway, I think the datastream is different for that ECM. The regular LT1 Scanmaster is set up for the later PCM.

You're thinking the 92 is an OBD II style as compared to our CCC3/OBD I systems? You maybe right and it may share that with the 90-92 F body speed density ECM.

Is there anything for those speed density data streams?

..EDIT...I believe this is the ECM

The 92 vette and 93 Camaro /Firebird use a unique ecu /datastream that the scan master will not talk to tried to make it work but no go. They are chip based like the older ECU's but a different datastream than the TPI or later LT1 flashed based ECU
