Bypassing the MAF

I recently hooked up a ZEX dry shot kit and the shot broke the wires on my MAF. I don't really feel like spending the money on a new MAF right now. So is there a way to bypass the MAF so my motor is running at the best conditions all the time?

LOL No.
This comes up a lot. Its a critical part of the system, you cant just eliminate it.

if you do a search it will show you the reason why you cant do it ,

i think it measures the amounth of air (using a heated wire )coming into you engine and then that info is fed to the ECM which in turn works out the air / fuel mixture. its a sensitive peice of kit that you cant do without

You are supposed to place the nitrous nozzle behind the maf! With the fine wire broke, There is no complete circuit, I belive the ecm will see the maf as maxed out at all times. Have fun driving it.

with no complete circuit wouldn't through the air/ fuel mix be MILES out as the ECM has no accurate reading

Exactly. The ecm is either gonna read 255grams/sec or 0grams/sec constantly, Not sure which, either way, you are fuked.

to be honest Fire if you have not got the money for a new or second hand MAF i would sell the NOS and get one. after all it will be useless without a MAF. good lluck though dude

thanks for the information, but I think I figured that one out. I was just asking if there was a way to bypass the MAF cause I have seen it done. I already got a buddy of mine getting me a new MAF. So I'm fuked here TraviZ cause I'm getting a brand new one and the car ran fine w/out the maf plugged in, but it didn't perform well. Thanks for your help though fin170703. I'm still gonna figure out a way to bypass this thing cause in theory I should be able to make a chip that can be plugged into MAF plug for the computer to read that will always tell the computer the best conditions. Gas will go to shitt, but I only drive the thing on the weekends and at the track.

Why bother with all that nonsense if you dont want it? Convert it to speed density. Done.

1. How can a car RUN FINE, BUT NOT PERFORM WELL.......sounds like a contradiction to me...

2. Research your THEORY a little more.....the only way you can get a "CHIP" to plug in and do that is to actually create just what you eliminated...A MAF SENSOR. Putting in a resistor or two as has been tried before will only give an acurate reading for a small area of the fuel/air curve, and 99% of the time it would be wrong readings. Thus computer has no idea what to do.

Stay with a MAF or to avoid it, Just goto speed density.

let me clarify that for you. I can drive the car around two with out a problem, but when I get on it such as trying to race, I lose power up top. Runs fine, but for performance it sucks.

Only thing I have to chime in is that you can run your car without the MAF, but you will not be able to get by in any situation (i.e. racing, casual driving, grocery getting, ect.) as well as the car should perform. The thing about the MAF is that the heated wire is exactly 75 degrees hotter than the outside air, when that wire is cooled by the air moving past the fine wire it measures the resistance of that wire and it is sent back to the ecm for correct air/fuel management. No aftermarket or "chip" will ever come close to the correct A/F ratio at any given range to replace the MAF. Thats all they are saying. Its vital, and whats the point of NOS if your car is not running at its peak performance? I would just say dont push it until its fixed. It will run, but like crap.

you could definetly run 9's with a properly built T5, i've see guys do it on T56's all the time(again properly built). also he was sarcastic if u didn't notice

On the serious side, Fire, you said that you're going to get a MAF, you made the right decision here. If you got a MAF car and the MAF ECM, you have to run a MAF sensor. There's no other way.

If you dont like the MAF setup, then convert to MAP, there are many articles on this on this 3rdgen site.

Concerning NOS, spray it into the air lid, if you have one. You should not spray near or directly at a MAF sensor, ever! I spray into the air lid and I have a MAF car, never a problem with the MAF. Also, do not spray just ahead of the plenum, you will have uneven distibution of NOS and burn up a piston.

I already got my new MAF tonight and my car runs great and I set up the nitrous properly and it runs great w/ that too. So I learned not to put the nitrous so close to the MAF. So much for getting some nice decent help from everyone. Thanks alot
Dude , chill out.

glad you got ya problem sorted , i think the new MAF was the only option ( and you probably knew that anyway and were just picking peoples brains )

you only have to see peoples combo's and times they are running on this board to realise that these guys do know what they are on about, helped me out LOADS of times,. But whent the same question is asked over and over again it tends to get a bit tedious

again, glad you got ya problem sorted

Hmmm .....

Info you allready had???? Then why start the thread and ask a question that you obviosly could have answered yourself?

Lock the post again? Let's see would you want it locked so that the rest of the world can no longer see and respond as we have?

I have a question for you though.......2 really...
1. Are you the son of the famed Dr. Z over at Chrysler?
2. Have you checked your crome muffler bearing to canuter valve connection? I think your problem might be there.






Just a Note for everyone else: Do you remember when you were 16 and read your second issue of Car Craft and thought you knew all there was to know about engines, cars, and racing?

And if you already knew the answer to your question, why start a thread???

Its like reading the instructions on the wrapper for a corndog when you get them at the fair....AND ITS ALREADY COOKED.

If you wanted another way of finding out, SEARCH.

I say...lets see some pics of this kids car! Probably isnt an LT1 intake. Ill bet its a stock L98 intake manifold. If he cant hook up a nitrous system properly, I seriously doubt he can install an LT1 intake and make it run.

Come on now guys,

Best forum on the best board on the net, and THIS is the best we can do?

It doesn't need to be locked if everyone just lets it be over with.

But since we apparently cannot do that, it gets locked. The original post has already been answered/resolved, and the additional content is only risking making us like one another less and less. So before it's too late, say goodnight, Gracie...
