Anyone running one of the LMAFs

[colz89gt]

Just wondering if anyone on here has ran the Lighting mass air flow meter? I am thinking bout gettin one and gettin a chip tuned for it, and was just wodnering whether anyone had had any luck with them.

I run one but I did have to add a mophia when I got up in horse I think it was 5?? rwh before I need it.

[colz89gt]

i've heard they help out quite a bit.. i was thinking about gettin one and gettin my SCT flip chip tuned for it. I heard the same bout 5rwh too.. what is the mophia??

[kennebellcobra]

The mophia is a extender. If you plan on making 500+ I would just buy a sct meter.

I'm gonna be running one soon on my 347. I'm still looking for the adapter wiring harness so I can use it with the standard 4 wire fox body harness.

If your combo doesnt have a huffer on it (blower) i wouldnt put a 90MM on there.Its to big.I would use at the biggest,an 80.My opinion.
One word: Resolution. The higher the metering capability of a MAF, the less resolution the meter has.

Resolution - basically, it has to do with airflow vs. MAF voltage. Two factors affect it: Physical size of the MAF, and injector size it's calibrated for. For example:



(all numbers are hypothetical and just to describe resolution)



Meter "A" - Can flow up to 800 cfm. Calibrated for 19# injectors

Meter "B" - Can flow up to 1000 cfm, calibrated for 42# injectors



Typical MAF airflow during normal driving will range from 50-200 cfm. This is the same no matter what MAF you are using.



Now, Meter "A" flows 800 cfm at 5v. Meter "B" flows 1000 cfm at 5v. 200 cfm difference, big whoop, right? Wrong.



Now, at 1.25v, Meter A flows 200 cfm. At the same 1.25v, Meter B flows 250 cfm. Do you see the trend here? When you start getting into lower voltages/airflow levels, the bigger MAF has a harder time covering the bigger spread of airflow with the set amount of voltage available.



Kinda like fooling with the "mouse" speed on your computer. Set it up to as fast as it goes, and you can easily move from side to side on the screen with a flick of the wrist. Try to select a single letter in a text document at the high speed, though, and it's a whole new ball game. The amount of distance the pointer covers vs the amount the mouse actually moves makes it very difficult to define exactly where you want to be when it is a very small area. Set the mouse speed to slow, and you can easily select what you want.

well i decided not to get the LMAF rite now i went with a PMAS 75mm unit.. i am going to try this and see how it works, i am planning on adding edlebrock heads and about 125 horse shot of nitrous in the next few months. whats ur alls opinions

what trans are you running? Also is the bottom end stock?

[colz89gt]

yea, stock 94 bottom end.. i'm running a WC T5... i am the one that bought the A9L and SCT off of you,if your on the corral too. after looking over what a few people said on the forums i decdied i dont need that big of a unit yet, maybe in a year or so i can upgrade to it.

[fst 5pto]

Yes you did buy my A9L and SCT chip. I would highly recommend looking into a better transmission, but some people will tell you a T5 will work, I personally found them to be junk and was quick to invest in a good transmission. Also, I am not sure but I think the pistons in the 94's are hyperjunk? Someone let me know If I am wrong, but if so I would just make sure you get a good tune on that chip. As I told you in the PM's it comes with a switch as well so you can have several tunes, one for N/A and one if you decide to run nitrous.

[colz89gt]

yea i have a guy lined up to tune it as soon as i get it hes in georgia...

I think Mr.KenB has those harnesses in stock. And I have a meter for sale :D
