Friends' car is running like ****. Prelude on an FMAX Turbo Kit. I'll give you just the details.

Loud hissing while accelerating
A/F gauge constantly RICH
Absolutely NO boost
Lost 1/4 tank of gas driving 20-25 miles highway

We stop and pop the hood... instantly smell of gas eminates. He just went home to grab the CEL code. Any thoughts? Thanks.

 

What fuel system?

What's his A/f ratio?


Sounds like a charge pipe is leaking.

 

sounds like an injector(s) could be stuck open and spraying fuel. check the plugs after a hard run to see if there if it is wet or not.

 

H22 ecu's do not like boost. Try using a different ecu

umm... all honda ecu's don't like boost... and the fmax kit comes with 2 extra injectors and its own controller.

 

I would have to check out that fuel system but I know he's using the FMAX Additional Injector System.

The charge pipe is what I was thinking too but he has a heatshield and it was too damn hot to check at the moment.

And the A/F was read through an autometer gauge, nothing like a widebang O2 or anything.

Thanks for the help guys. Will report in the morning.

 

sounds liek a charge pipe is off. and mf2

 

Yea I'm not a big fan of the MF2 either but he says it works great. Apparently not.

Any A/F gauge like autometer etc is going to be inaccurate. The only good thing about them is when at WOT it'll sorta tell you if you're running rich or not.

I know that's why I said it's nothing like a Wideband O2. Oh well it's something at least.

 

does the mf2 light up red when open?

check for vaccum leaks and if its properly connected...

just some thoughts cause I know for a fact those kits are POSs
did you install a 3 bar map sensor and missing link?

 

i didnt have that same problem and i didnt open my hood to see fuel squirting out of my injector. it turns out i broke a o ring putting in the new injectors and i didnt drive it like that for about 2-3 days...
i think you get the point

Well thankfully there was no fuel spitting out because we checked the injectors. Sh*t I am yet to talk to my friend about how the car's going.

 

Park the car till you get real engine management and a wideband.

 

Yea this kid likes to buy real nice parts for his setup while stinging on important parts. He doesn't even have a V-AFC, let alone real engine management. How is it supposed to be tuned?? Ah well, he's not really taking good care of it since he got his gixxer.

 

what is your exhaust ????? maybe problem there ??? and air/fuel ratio to.....

COUTO

 

HIS exhaust is Apex'i N1 2.5" and a 2.5" downpipe.
