IC17 Bypass for Honda OBD1 ECU
Replaces TA8903SN
This component can fail on original or chipped ECUs and cause the following symptoms:
- Fuel pump no longer primes
- Fuel pump primes randomly / after a delay
This improved version allows compatibility with all OBD1 emulator systems without causing reset issues, a known problem with Moates Demon/ Snake EMU/ ECU Tamer when using low-end products marked as "IC17 emulators" on the market.
Note : this component causes the loss of LTFTs every time the ignition is switched off when installed on an original ECU, which is insignificant on an ECU chipped with an open-loop map.

If the ECU has a solid CEL (code 0), the issue may come from somewhere else. Contact mirobuilds for repairs
