ok on the corvette os the difference between man/auto is H0162. auto is serial data, man = pulse.

I know there's a bunch more parameters defined in hpt, which i could easily bring across, but there is also a holden commodore manual tune file that im wondering would be a better base file since it doesnt use a trans-axle setup. let me know if u want me to post the file. u could just try a segment swap on the corvette os from the holden 1.

Does the holden commodore have the same gmlan as the gm truck?

How does one do a segment swap? I know of calibration flash, and full flash, never heard of a segment swap

i would bet that the commodore would be more compatible then the corvette changes since they used a lot of older serial comms gear for the dash clusters. where as commodore gear was all high & low speed can to modules.

You are a God send.

Worked like a charm. The rpm on the dash works and the speedo is at zero when at a stand still. So its a win win.

I will let the designer for the gateway know there is an OS that will work

Thank you again

what else does the gateway module do?

[Naf]

It converts the GMLan so the Defender TDCI 2.4 gets RPM, engine light, oil light, batt light, coolant temp, and that is all.

The defender cluster/dash is semi canbus, the speedo functions from the sensor and the Transfer case diff lock also functions directly from the sensor.

Its a complicated simple device.

All I know is now I should have cruise control, and a manual transmission. Lets see how it all pans out next week,
