I wonder if you can help. My Westfield AJP uses the Omex ecu to operate the cooling fan and is currently set to turn the fan on at 90 and off at 85. Am i right the TVR uses the radiator fan switch to control this operation and turns it on at 95, but what temp does it turn it off again ?
i want to update my ecu to match the hotter running as my cooling fan seems to burning out my relays as it is probably either running too much or turning on and off too much ?
Thoughts appreciated.
apart from this it drives wonderfully smile
Thanks

When you say burning out the relays, what do you mean exactly? The relays should be up to the task regardless of what temp you try to hold the engine to and should cope years. If you think they're not up to it I'd upgrade them, not change the fan cut in/out temps.

Yes thanks Steve, further investigations means no longer focussed on temps but on a higher capacity relay and current dissipation as its the high initial current on switch on to protect from. thanks for coming back.
