What have you done to your MSP today?

[livelyjay]

Just curious for some opinions on relocating the MAF. I get stumbling at idle when coming off of acceleration with the upgraded SMIC. I installed the SSAFC but it didn't seem to do any good at idle.

I would think relocating the MAF would be beneficial because it would then be reading the exact air volume right before it enters the TB. Who's running this setup and what are your opinions on it?

Pretty sure most people with aftermarket intercoolers are running relocated maf. 6" from throttle body and 6" more to bov/bypass.

Im not.

Here's mine.

Not me either. Everything is on the stock location still and runs great.

I had stalling before I relocated after doing my FMIC.

It's not so bad when the weather gets warmer, but this winter has been bad. If I accelerate and get into boost, then let off the gas the car will stumble and sometimes stall. In this scenario, the A/F ratio would get really rich and if the car kept running would lean out then setting in at stoich.

Next week I'm going to be putting in a new radiator and coolant hoses plus new WGA so I'm going to put the factory SMIC back in and see if the stalling continues. If it continues it will point to a different problem. If it goes back to normal I might sell everything or relocate the MAF.

You are venting metered air, yes???

It is expecting to see the same volume of air that passed through the maf to enter the engine... That isn't happening...

Say the MAF reports XXXcfm, it reports back to the ECM, the ECM says, I need to put this much fuel into the engine for this much air...

To make this simple, let's use simple values for representation purposes-

For every, say, 10 units of air, the ECM wants to put 1 part of fuel to those- 10:1

Okay, your MAF sees 10 units of air, reports back to the ECM, ECM says, okay, let's put in 1 unit of fuel. It's all fine and dandy.

The car is at WOT, see's 100 units of air, the ECM puts in 10 units of fuel... Well, 100 units of air come through the MAF, is compressed, put through the piping and core, to the BOV that now vents, say 20 units of air to the atmosphere, 80 units of air to the throttle body, now you've still got 10 units of fuel being put into the combustion chamber but only 80 units of air... see the problem here? You have more fuel than air in the chamber.. it's now a rich mixture.. Well, now you've got your lambda sensor seeing rich exhaust gasses and it begins leaning it out to compensate for it...

I'm not venting, I'm recircing using OEM pipes and valve. Only aftermarket part is the SMIC.

boost leak, bad plugs, plugs not gaped properly, this list could go on of things you should check

 

[Preferio]

Sorry, thought you were VTA

With a FMIC

170 miles out of half a tank of fuel. Of course I was using the car simply as a means of transportation of the weekend with the girls in the car so I wasn't WOT the entire time. Interesting to see what I can get out of it when I'm not on it all the time, though I suspect the next half of the tank won't last as long.

Have you upgraded 5th gear? Made a big difference with cursing.

 

[rally2003]

The most I have got out if a tank of gas was 456 miles. No boost or fun involved.

A loooooooong time ago. And now I am using a '97 Probe transmission with .717 (I believe) 5th gear.

Yeah, other than a body kit-equipped 95-99 Neon with fresh temporary tags thinking he's rocking the most ballin' SRT4, I had to do one quick WOT pull while in 5th on the interstate to show him he's retarded, I pretty much grannied the car this weekend. Plus that oil leak doesn't make me feel great about being hard on it.

Also, I'd like to say this: I hate every MSP owner who didn't vote (for me) in the MotM!!!!

Sorry bro, needs more personal style on the appearance in my opinion.

Sorry man. Had to vote for local guy.
