I wanted to put all of this in one place for reference.

PRIMARY INJECTORS
RED 290cc

6-PORT SECONDARY INJECTORS & PRIMARY 2 INJECTORS
YELLOW 380cc

4-PORT SECONDARY INJECTORS
BLUE 480cc

Injectors are Bosh disc-type, high impedance (13 ohm) with a Denso connector.

not really..

same answer in the long run..

less ports = less injectors..

6-port = 6 injectors (2100cc total)
4-port = 4 injectors (1540cc total)

less ports, less rpm..

So I have a new engine in my car thanks to some water that hyrdolocked my old one... dont ask. Anyway, the fuel trim is off according to the mechanics. Well I asked someone at Mazsport, they said maybe the injectors were backwards. Any ideas? Im kind of confused seeing as it's two and four not three and three or something like that...

Try looking at the first post of the thread.
If that doesn't answer your question, nothing will.

BTW - you can't "hydrolock" a rotary motor.

rotarygod

I can verify that. Flood waters couldn't do it!

Well then the techs at Mazda are idiots. They tried to turn it with a breaker bar and it didn't turn, with the spark plugs removed. Any ideas?

the_duke313

yup i agree mazda techs are idiots. i wont be taking my car there unless absolutley necessary

swoope

iTrader: (5)

If it were "hydrolocked", pulling the plugs would "un-hydrolock" it.
What led to the motor being in this condition?

carbon lock?

Possibly. Though, you seldom hear of a car stopping in its tracks from carbon lock.

Well lets see. Here in Iowa, about a month back, we had a lot of rain coming down. Well one night my car and I went through this puddle of water. The AEM CAI decided that it would suck up the water instead of air, causing it to stall. Pushed it out of said puddle and let tried it. Nothing. Left it alone for a day to dry out and tried to turn it over. Nothing. Towed it to the only Mazda dealership in town, thinking they should know what they are doing. They said they took the plugs out and tried to turn the engine with a breaker bar and still couldn't get it to budge. So they replaced it. Then after I had it for a few days, the CEL comes on. I take it back, they say ignition coils. They pop new ones in and find that the fuel trim is off. Excessive as they say. A week later and I'm still car-less. Worse yet, they gave me a damn minivan. So please help in anyway possible. I asked a tech at Mazsport, they said maybe they got the injectors backwards, primary and secondary. From what I read, it might have been the MAF or O2 sensor. According to the techs though, they said they can test the MAF and found it to be OK. Now they want to replace my AEM CAI with the stock airbox. No thanks. Any ideas on how to keep my CAI and fix this fuel trim issue? Take it to a tuning place and reflash the ECU? I have no freaking idea...

Strike one.


Awfully nice of them. I presume this was under warranty?


Strike two.


He winds up for the pitch....


Strike three!

They left your snorkel in the car, but gave you a free engine?
How, exactly, did they "test" the MAF?
What code did you throw?

Hey guys, I would like to announce that I am running my car with mazsport injectors with a stock ecu
