ok you might recall that I installed a bigger MAF claimed gains and most of you said no way. Well I replaced my injectors today with 30lb ford injectors, because my factory ones were having trouble with the increased pressure necessary because of the bigger MAF. So I, without thinking, decided that I could remove the rest of the restriction in the bigger MAF since the bigger injectors would make up for the air not being measured. Well they helped but I should have calibrated the fuel pressure with the new injectors before I modified the MAF any, thats the without thinking part. So now the car would only run lean so I figured I could extend the wires holding the MAF sensor resistors so that the resistors where in the middle of the MAF therefor measuring more airflow. Well I found out that the wires supporting the resistors won't solder. So I put the car back together with the resistors removed from the MAF and started it up. It idled at 2k rpm then went to 1k rpm after it warmed up a little. Heres the wierd part, it now pulls much stronger even till redline, I even had my bro in law ride along and he noticed the change as well. So basically I have no MAF but it is definately faster and doesn't go lean, in fact the O2 gauge reacts instantly where before there was a slight delay between flooring it and it going rich. Yes I know the O2 sensors aren't very accurate so get over it already. Anyway why the gain?



So get over it?

Why'd you post this crap anyway? I haven't decided whether you posted it because you are proud of yourself, unsure and want advice, or what?

So let me assume you put it on to seek reassurance...
Then let me say that was very foolish to cut apart your maf and try to move the resistors. They are welded on, not soldered. They are calibrated at a certain distance with those special metal posts and there isn't a damn thing anyone can do to change that. EVEN PRO-M won't move the resistors because the MAF is useless afterwards.

So as to it pulling stronger: It is probably running leaner, that will make your car pull stronger. It is very possible that you are running close to detonation but you could be lucky and the car is injecting a precalculated amount of fuel when you have a non-functional MAF.

You should put a new MAF in. Don't worry about the restriction of the center post because it isn't a restriction! It won't hurt one bit.
Then buy an SAFC or eManage and tune in your Air Fuel. That way you have reprogramability.
Break down and do the $75-$150 for 2-3 dyno runs with some A/F data and tune the car in.




Not to start anything big here but that is even if he is telling the truth.

For example he says he did ATX-MTX swap but didnt swap the engines, which is impossible because MTX engines have a pilot bearing on the end of the crankshaft for the clutch.
So he couldnt have swapped the trans. and not the engine as well.

So who really knows with this guy.
