K I'll give it a look today. There is a guy in town who tunes cars for $200.00. So next week hopefully IM going to have him tune it for me. Any other suggestions on keeping everything cool under the hood? I can drive to work which is about 10 minutes away and it gets pretty hot.

The closest (big) city from me is like an hour and a half away but not sure if heat would be an issue not to drive so far.

How do you plan on tuning it? You don't have any fuel management.

Engines get hot. That turbo gets up to couple hundred degrees on the outside. Boosting or not. They make turbo blankets that wrap around the exhaust side which is supposed to help, but I've never used one.

You really shouldn't have to worry about the temps in the bay. Just keep your eye on the coolant temp and make sure it doesn't start raising up. With the FMIC and the A/C, you're blocking air from going to the radiator, so really just keep on eye on it. You have both fans in there as well or no?

Yea there is no way to tune your car at all. You have absolutely no adjustment in that fuel system. Thats why I said buy a wb02 and just make sure your putting enough fuel in the motor and you will be ok. The trans are good for ungodly amounts of power somehow. People are putting down 500+whp on the stock tranny. I guess its bc its fwd and it just spins the tires instead of really loading it up. Your not pushing that much power so the clutch shouldn't be slipping but I guess it is possible. Like dave said if the rpms go up and the speed doesn't the clutch is slipping

Wait IM confused. I have an FMU. Or is it a different thing? Been meaning to say I have an MSD, just never got around to hooking it up. Would that help make the car run better in some ways?

SilvrEclipse · #**155** 04-10-2010, 05:15 PM

You have an FMU. All it does it raise your fuel pressure 12psi for every pound of boost to force fuel into the motor. There is no adjustment on it to tune.

You mean like an MSD coil pack? It may help some by giving the motor better spark. Also did you change your plugs when you turboed it? You should be running brk7e or bpr7e plugs. one heat range colder than stock.

An MSD ignition system. Sorry should of said that. I have 10mm plug wires by Magnecor running now. What is the difference between brk7e and bpr7e? Which is better for stock? And where is the best place to purchase them?

Which MSD ignition? the DIS 2? You really dont need that right now. The stock timing maps are fine for low boost. Both plugs are basically the same. Some places only carry one or the other tho. Any parts store should have them. If they say they dont then just tell them you want a plug 1 heat range colder than stock

Advanced Auto carries NGK BPR7ES plugs for $1.99 a piece. my .02 cents

Ya dis 2. But why is my idle at 2rpm? I adjusted it and it will not go down at all.

SilvrEclipse · #**160** 04-13-2010, 09:57 PM

2k rpms? A motor can only idle high for one reason. Its pulling in to much air at idle. This can be caused by a few reasons, vac leak, IAC is bad, throttle cable adjusted wrong, etc

And you dont need the DIS 2 either. Stock ignition timing is fine for low boost. You need it above 15psi which you wont be able to do unless you build the motor, but even then you will need to upgrade fuel and most of us run megasquirt which does ignition timing also so if that was mine I would sell it for a couple hundred.

The only reason you should keep it is if you are planning on building the motor and running portfueler to tune the fuel with.

Cavalier9696 · #**161** 04-14-2010, 01:46 PM

Ya I thought about selling it. I Have a brand new IAC just never put it in. I'll try that first and see if that fixes it.

How bad would it be to run W/O my FMU? Just fuel line from firewall to rail? Cause my FMU leaks bad on the part from the fmu to the rail. Is it ok just just run w/o it until I can find a hose barb to put on my fmu?

LandoAWD · #**163** 04-29-2010, 10:20 AM

Uhh, doesn't an FMU account for boost (rising rate)?

Stop half-assing stuff.

david-b · #**164** 04-29-2010, 10:41 AM

No it's not fine at all. For every pound of boost you hit, the FMU raises fuel pressure by 12psi. Obviously if you NEED the FMU when going turbo, taking it off is not going to work. You'll run lean, hit fuel cut, and blow up your motor.

Don't drive it and get the proper fitting or whatever is leaking.

I picked up some barb fittings from lowes that worked fine. On another note how did you install this FMU. You didn't put it on the fuel rail feed line did you?
