easy power mod

i saw this mod on a toyota truck performance site (cause i used to have one before my MX) and they have you take off the MAF cover, rotate the gear inside about 3-5 teeth counter-cloclwise and reseal it, i did it 4 teeth and my car runs richer and has more power (92 SOHC I-4), try it out and tell me how it goes for you

Sounds pretty interesting. Just a warning for anyone that wants to try it. You will lose gas mileage, and a new MAF sensor is not cheap! I am curious though.

how does it power ur car up?

yea, i forgot to say that, make sure you are really carful about taking the cover off, pull up on the flat side, i did it because i have an extra MAF so its no big deal for me, your car will also stink at idle, like unburnt gas, just incase you dont like stink, also make sure you mark where the stock position is so you can change it back if you need to, this shouls work on any MX V6 or I-4it makes more power by making the injectors put more fuel into the engine making it put out more power[ July 08, 2003: Message edited by: papa roached ][ July 08, 2003: Message edited by: papa roached ]

Making your car run "richer" doesn't increase performance. Too much fuel is not good, you will just spit the fuel out the tail pipe or wash the oil off the cylinder walls. Not to mention it will hurt you O2 sensor. You want to tune the car to run leaner as Mazda has tuned the car to run rich from the factory to prevent detonation. A butt dyno is no replacement for a real dyno.

Yeah leaner will make more power.. heat is good.. i know it can sound like i am sarcastic but its a long story but its true.. i could get my brother to explain the thermaldynamics behind it.. but hey he lives a hour from here =]
Really you might feel it in your pants cause a rich low end lends more tq.

To answer the how question, all your doing is fooling the ECU into dumping more fuel into the engine coz it thinks the butterfly is open further than it really is.The downside is that the ECU will get readings off the o2 sensor that wont jive & it will try to compensate for the change. Sounds like a good way to eat some high dollar parts.Running rich is bad, esp if you can really smell the gas. As previously mentioned, you're washing the fuel off of the cyclender walls causing premature wear & eventual loss of compression. You'll eat O2 sensors at a hight rate, and you'll run the risk of fouling plugs and of course depositing tons of carbon in the exaust system, valves, & cat.
You might feel you have more power in the low range but you may find your top end will suffer.Bottom line, it sounds neat, but it's not smart. But hey, your cars, do as you will.

Ok, so it was said that running lean is better than running rich. And it was also said that the cars were set fairly rich from the factory, so my question is, could you do what this guy said, except instead of turning the gear to make it more rich, turn it to make it more lean? Would this give you some more power?

RX-7 air flow meter adjustmentsThe page is from within the vast knowledge found on Solomiata. The instructions are based on the M1 Miata (uses same meter as we do) and the conversion to the RX-7 meter. Same instructions apply to our car.

i didnt know they were tuned from the factory rich, well, either way, i have never heard of this mod on here before, i plan to drop a 1.8 DOHC in it soon anyway, so the wear on the motor does not bother me but i will give the lean a try

Many people with certain MAF sensors adjust the sensor output as is described here. I have heard of it with a Mazda B-series before and I have heard of it on the Mazda F-series used in 4-cyl Probes.
