hey guys im thinking of geting my rex remapped but i dont know anything about it. The cars running rich this is the main reason i was thinking it needs a map i stuggle to get it through mots, but its also only running 240 bhp which as far as i know is under powered, i got a 93 fd3 standard engine and its only boosting up to 0.8 this normal? would a remap help?
I think standard fds push out 0.8bar anyway (12psi...ish). Book it in for a dyno tune mate and they will be able to diagnose any problems with it. 240bhp is alright for a standard rex.
A dyno tune? Can any1 do a rx7 and can you tune on the standard ecu
no you cant tune a standard ECU you need to buy a an APexi Power FC ECU
Is the car Jap or UK? Reason I ask is that UK cars were 237bhp standard, so you may be right on the money anyway.
what are the hydrocarbon and co2 readings for mot? maybe ur airpump broke or cat is gone hence fail mot?
if its completely stock i cant imagin a remap would help maybe sth else going on?
Standard boost on a pre 99 rx7 is 0.68bar and 0.74 for the 99-02 models.
You need to spend £500 on a powerFC ecu and give a rotary specific tuner another £300 to map it for you otherwise you will, at best just keep chasing your tail or at worst give it to the wrong person to tune on a dyno and get it blown up.
For your money spent you will get approx another 30-50hp and the knowledge it has been done right.
My 2p anyway
