running car with no maf ?s
running car with no maf ?s will it hurt the ride or screw up the ecu? I know the car would just stay in speed density right if i pull the maf? Or do i have to pull the maf an o2's?..i know i could get the car tuned for speed density but im still trying to decide if im just going to swap over to carb or not.
There is no relationship between the MAF and the O2s.
The PCM can't be harmed by pulling the MAF.
But the PCM is tuned for a MAF, so you would want to retune if you wish to remove the MAF.
An easy test is to unplug the MAF and drive it for a while. See what you think.

yeah thats what i thought..will my o2's still give my pc feed back an adj some what? I know running with no o2's would be like running the car in open loop right..my rides a 94..i already know im going to need a tune seeing i got every bolt on..i just want to ditch my maf,k&n cai an run a filter off my throttle body with my air inlet temp sensor about a inche fromt the tb base....i drove the car for a couple miles before my opti went with it unpluged an it just seemed to run a tad richer..but i wanted to make sure i couldnt hurt anything by doing it long term..
yeah i got to find some one with that stuff i can use..i would buy all the stuff an tune the car myself but for the cost of all that stuff i can convert to carb now an plus when i go to my lsx turbo deal none of that stuff i could use seeing if anything i would swap over to big stuff 3 if i wasnt doing a blow threw system for it.

Verdad Gallardo because at the track ill run no filter..meaning no restrictions..no curves or any other restrictions..just open tb with my air sensor ..car will make more power like that vs running a 2ft long 3.5 inche tube with a filter an 2 90 degree bends..
also im not ruuning my stock rad im putting an after market in the car to gain clearance an an after market fan..ill also be pumping ice water threw the motor after i get the oil up to temp and ill be iceing down my intake..this aint my first rodeo..

But alot of stock eliminator cars run open TB's.
yep..look at gizmo's cars..im doing my car in a pro stock,super stock manner..ill be using alot of there tricks also..ill probley even run a vac pump on this bolt on motor..ill also only run enough oil for start up,burn out an then 1/4 run..then ill kill the motor..i feel i can put the record around 11.teens or maybe even 10s in good air..
Wouldnt running the car with no maf throw the pcm into open loop. Thus making your o2's useless. Its my understanding that your pcm doesnt use o2 reading till its in closed loop.
This is correct. He was planning on enabling speed density mode though (or at least I thought he was) which will rely off the VE tables, map sensor, etc rather than the maf, and of course the o2's in closed loop.
good info on that.now im unassure if i even want to pay for a tune,slap my new 02s in it or just do the swap to carb..all i need is carb,intake an th350 trans..
ill probley make the record pass in carb trim though seeing the fuel i want to run will kill my o2's or any o2's now that i think about it.
whats a mail order tune run? im trying to weight my options now..
whats a used maf,intake with tb,fuel rails an injectors sale for on the avg?
