Bridgeported FC won't idle
I recently bought an FC that was bridgeported and it won't idle. I knew this going into the purchase, I was just wondering if anyone knew how to fix that before I decided to take it to a performance shop. Also, this FC is my first foray into modded vehicles and rotaries. Halp please!

The increased airflow due to the bridge will make the fuel mixture too lean to idle. The configuration of the intake port on the bridge may preclude it from ever idling below say 1500 rpm. More fuel will help. easiest way to accomplish, increase fuek pressure. Walboro hp fuel pump. the biggest one they have. I think its 255 gph, or lph, or whatever.

Wow...umm ok. NA with stock intake. What does standalone mean? The car starts and revs no problem, but when it's cold and you let go of the throttle the car stalls out. I will look into the fuel pump, I'm also looking into an intake. I'm a rx7 noob and from what I understand the person who modded the engine isn't very reputable at making them run well once in the car. I keep asking for a step by step list of what was modded on the car and he keeps telling me he'll get it to me, but he already has my money so I'm not sure if I'm ever getting that.

if you're attempting to get it to run semi properly with a bridge on a stock ECU it's going to take more technical messing around than i am sure you are capable of. a standalone is an aftermarket reprogrammable ECU.
even people who know these cars like the back of their hand would have to spend days swapping parts to attempt to even get it drivable dicking with the stock ECU in combination with a bridgeport.

Yeah look into the megasquirt or maybe a haltech, those come up on here pretty cheap sometimes and they work great. BUT if the port job wasn't done right you probably have more issues than just a tune problem. Also when a rotary is bridgeported it typically won't be able to idle lower than 1500rpm, it's similar to putting a huge cam into a piston engine.
