mass air

[90blackbox]

was wondering if i could take the sensor out of my 90 crown vic and put it in a different housing so that i could keep the 14 pound injectors but get more flow out of it. it has the original california small housing.

I am planning a full HO conversion but would like to do it in two stages first the upper intake throttle body egr plate and heads and after i get injectors the rest of the electronics.

Unless you have also installed a GT upper intake and throttle body, there isn't any point in it.

Doesn't work that way anyway. You'd just make it run like crap. You cannot swap sensors like that.

and like pirate mentioned without supporting mods and a much better flowing intake/exhaust and a better intake tube and air filter housing it's all a waste.

I'd think swapping a non-ca lopo sd ecu and removing the mass air would be more helpful.

The sensor is calibrated to the sensor housing, so switching it to another housing wouldn't work.

got the upper and lower intake already just was wondering about the sensor housing. I work at napa so i sit there on the weekends and try and figure out what kind of parts i can use from other vehicles. I saw one of a 97 exlplorer that looked like it flowed way better but i havent picked up a new set of injectors yet so i have to wait I was just looking for a way around it

You can't just go swapping mass air meters around. You have to get the ECU tuned with the proper MAF tansfer function.

Going full HO/MAF conversion and a stock HO MAF would be fine, other than that, your best bet is an SD conversion.

[gadget73]

What he said. Unless you can find the actual transfer function of that particular meter to match with something else, you're sort of stuck with it. You've got a fairly rare car, so there isn't a lot of information on that mass air system.

yeah the damn thing is made in canada and is a p72 vin, like a taxi i believe anyway my old mustang was speed density and i spent the whole time i had it wishing it was a mass air system it was an 87 gt convertable. its strange that you guys feel that the older system is better.

The 90-91 California only cars got mass air. They used some funky tune and a special ECM. The mass air meter I think is from an Escort or something really miserably small. SD has no restriction in the intake and probably will give you a bit more fuel.

Honestly SD isn't a downgrade, though it does lack flexibility. On a stock or nearly stock engine, it runs spectacular.

Its more that Mass Air isnt realy needed until a certn level of mods is reached.

yeah that makes more sense i already got the e7's and the upper and lower mustang stuff it came with a throttle body, egr plate and shorty headers so it seems all i need is a mass air sensor injectors and a ecu out of a mark vi my last post had a typo its a p71 vin

[90blackbox]

so i guess the question is what mass air sensor can i use once ive done a full ho conversion just a mustang one or can i use an explorer

You will need a Mass air ECU and its matching Mass Air meter. A9Ls are popular. Mark 7s except possibly HO ones in calli didnt have mass air. You will also need 19# injectors

have you ever looked at the tiny pee hole in the mass air housing?? speed density is every bit as good as maf and some people actually prefer SD.. I myself think it wouldn't be worth it unless you bored the housing out.

when you do the full conversion you would use the stock HO maf housing or similar.

Use a mustang HO one, Since the HO ECU has the proper transfer for that meter.
