Any idea why this would occur Hill assist light seems to trigger on fast accelerator liftoff after full throttle and boost. Usual scanner won’t check for error codes with link installed as it wants stock ecu details which it uses to look up which car and then connect to rest of the controllers. New motor does pull more vacuum on deceleration but not excessively more. But no ABS light and brakes are fine so currently discounting vacuum issues.

Is the error when the engine is off or while running? what about if just the water temp dash gauge was used? Scaled for mid point being 85% and 5% per mark so 75-95% overall. that maybe less likely used by systems. for Sti fuel gauge is still resistance driven so can’t reuse that. could put DCCD in test mode while sending fake data since the car wouldn’t be moving.

Is it possible to alter what is sent to the dash cluster via canbus for plugin ecu? Can I trigger the ecu to send ethanol percentage to the rev counter scaled rather than rpm? eg e85 would be 8500rpm. The next step would be to also trigger the fuel pump at the low speed setting and sent fuel temp to the dash water temp. With conditions that engine is not running and the input trigger is true (DI or resistance ladder keypad button held down) as well as it would only be used to mix e100 with 98 already in the tank. This saves wiring up a ethanol or addition canbus gauge. v11 Sti
