A taste of whats coming...

Correct. Do you think its running rich or lean?

Make sure the FMU is hooked up properly.

Ill check that out tomorrow when daylight gets back. Getting cold out there too haha!

Other than that, I'm almost wondering if the SAFC-II is screwing something up. If it's easy to do, disconnect the power wire to the unit. Then do disconnect the MAP interruption, before reconnecting it to it's original configuration. Perhaps it may fix things until you can configure the SAFC better.

Worth a try. Thanks!

By the sound of it, it almost sounds like your experiencing something similar to fuel cut (if not fuel cut itself) - so I'd say you're running lean.

Get that manifold flange fixed asap. With that hot exhaust getting by that gasket will eventually burn it up and even a flat non-warped flange will be pointeless since those runners won't be sealed off, allowing more and more to burn.

This will cause you to have..I guess you could call it turbo lag...I learned the hard way. 6 psi and 6k rpms Lol

Will do. I wont be doing much boosting till I take this thing down to the local turbo shop and get a wideband dyno tune put on it next Saturday or so.

This is an odd question, but what would occur if I had somehow managed to hook the fmu lines up backwards?

[Livid]

The bottom line of the fmu is the return line to the tank and the side is to the fuel rail. Just trace them back it's not to hard. Also you might want to check your idle fuel pressure.

[VelocitàPaola]

Just to help you visualize the set up...

[selmerguy]

if you want a easy filter for yout ml lift up your back seat and steal some foam. i have been using it for awhile and no problems.

hooking your fmu up backwards would cause you to run rich and idle/run bad. lots of black smoke.

Im doing the good ol' work-n-lurk right now.

Anyways, while browsing/searching about, I ran across this in another thread:

The reason I say this is because if your planning on tuning with an SAFC, you might have to scrap the missing link idea because reports say "they don't work together" But some people say they do.

Im running a SAFCII and an ML. How can I get rid of the ML, and just use the SAFC to keep the map sensor from seeing positive pressure?

you cant. i ran the ml and the safc2 with no problems. and the safc is worthless for our cars. the safc just changes the map voltage to adjust fuel. it wont stop it from seeing boost. your problem is the filter not being in your ml. you should hear it as soon as you open the hood.

That fuel setup diagram is wrong. First off you dont use the stock fpr with the sfmu, you remove it. Secondly the reture line is not on the same side as the feed on the fuel rail. Here is a diagram I made a few months back when I was doing my fuel system. It also includes all part numbers and where to buy the parts.

He has an FMU, he needs the stock FPR...

It's a schematic, sue me.

[Randomrage]

Yeah, missing link is fixed, as far as I can tell. Doesnt bog as easily at stoplights, but it still does it occasionally. And Im still getting mad hesitation at -10 on the gauge, if Im easing into it.

Im taking it down to the TurboTune in G-boro next Wednesday and let them do their wideband tune thing. Then Im getting a real a/f gauge, and a fuel pressure gauge.

Thanks a million for the help guys. Ill post an update next Wednesday, if not before, and hopefully a dyno sheet soon after that.

Edit: Yo, is it always like this? You know, the first time?

The diagram for the 95-96 early fuel system looks just right to me. I've got one, and I think it's possible that my stock fpr is on one side, with the return/supply lines coming off the other. The FMU setup looks right as well considering the SFMU was not even mentioned as previously stated. Good luck with that dyno tune, let us know how it goes.

Thanks dude, I appreciate it. Im at my wits end (and possibly mechanical skills end) on this. I cant wait to get her running right.

[DSMcrazy3]

Did you get the flange fixed yet? I wouldn't dyno-tune until everything that you can fix is fixed...Seriously...

Agreed good job Velocità.

I too have a 95, and on mine, the feed and return line both attatch on one, with the FPR on the other

Im going to let TurboTune do what they need to do to it. Im still not sure if the gasket is bad, or if one of the flanges are warped. But they have replacement gaskets, and they can plane the flange if need be.

Im taking it down next Wednesday to let them look it over really good. Then, after I finish breaking it in, and everything is ok like you said, then dyno time.

I know you're getting it fixed, but it doesn't matter if you would be boosting. When you turn the car on, that gas will be passing that gasket, burning it. The higher the RPM you drive, NOT boost, the more gas goes by it, the hotter it gets, the quicker it goes.

Glad to see you're getting it fixed

[Randomrage]

Oh great, my coolant reservoir is full of oil. I guess my head gasket is blown? Now I dont know what the heck to do.

[DSMcrazy3]

Really? Man...Did you boost heavy or anything like that at any time? There COULD be more problems than that, with the other symptoms you were describing..Lets hope not though. Run a compression test and tell us what you get..

Sorry to hear about that man...
