Rx7 FD - Elite1500 troubleshooting
Hi Folks,
I have searched but have been unsuccessful at finding any help for two issue which my new build is experiencing.
Spec:
13B REW half bridge
T04R turbo
FFE 36-1 Mag trigger wheel
IGN1A coils
ID750cc - Primary injectors
Bosch 1650cc - Secondaries
1. The manifold runners are glowing red on idle after 2-3 minutes.
I have verified that the base timing angle is correct having zeroed both the leading and trailing and checked with a timing light. Adjust to 92* with a FFE trigger wheel to get the red mark aligned. Have also checked trailing and leading is correct for the front and verified for the leading on the rear (added a mark at 180* to confirm).
Car is idling erratically varying from 1400rpm to 2400rpm depending on how I play with the ignition.
2. IGN4 - Rear Trailing coil is not firing
Identified when trying to trouble shoot the red manifold but the IGN4 is not firing. Have put in a new coil which fires if I hook it up to another plug. I have verified continuity for the grounds and between the ECU and trigger wiring. Confirmed the coil is getting 12V.
Help would be massively appreciated.
Regards,
Mike

Keeping this up to date in the hope that someone can guide me in stopping the manifold glowing.
I got the zero demand table disabled and the manifold still got red.
On a positive, I fixed the trailing plug not firing. The shielded cable shielding was shorting to the pin, meaning the signal was grounded. Pulled back the shielding and insulated and all coils are now firing.
