FC boost problem
hello everyone.
I have a problem with my FC TII
my set: FC3S S5 turbo II of 1991
- 3 inch exhaust
- admission
- FCD
- ACV out
- Walbro fuel pump
- Fuel pump rewire
I've tested with the parts of a friend:
- Ignition coils (trailing / leading)
- Airflow meter
- Pressure sensor
- intercooler
my problem:
by being in 3 rd gear (same in 4 and 5) was 2000 rpm I put WOT and the boost pressure take 0.8 / 0.9 b and around 3500/4000 rpm, violent backfire arrive
but if I release a little the backfire stop, and I can take all the rpm
sorry for my bad english

hi ...
good, in the end I solved my problem !
I solved by redoing all my ground at the top engine (for injection), simplifying the circuit with all the air pressure switches
