whats up guys? im about to buy an 86 mustang and i am having a difficult time figuring this out?.....i looked under the hood and i noticed that the mass air senser is missing and it looks like the intake shouldnt have one. do the 86 mustangs come with the mass air meter.

 

No mass air meter on 86 and 87 Mustangs, 85-92 trucks and other cars in the F/L/M lineup.
Your engine is Speed Density control.
The main fuel control is the MAP sensor's reaction to intake manifold vacuum versus engine load as opposed to using an air meter to measure load demand.
Otherwise it uses all the same sensors the mass air engine uses.
The SD engine is sensitive to intake vacuum levels making a performance cam change limited but not impossible.
I run a supercharged SD engine with special control functions to get around the MAP sensor function, when in a boosted condition. The MAP doesnot like positive pressure applied to it.
Hope this helps a little in understanding your system.

 

Right on the money. You can add MAF to your speed density car, its relatively easy to do. The kits are on ebay all the time. On a side note, I just sold an 86 mustang with 60K original miles on it. !986 was the weakest 5.0 mustang produced due to the limited breathing capablilities of the heads. In 1987 they reverted to the E7TE type heads and that gave the ol pony another 25HP

 

Hey guys thanks so much for the responses, that solved a lot of my problems...thanks everyone
