as far as the car running, the map does nothing. Its not a primary sensor on fuel delivery

Unplug it and see how well your car runs, the map is still quite important to your engine, just because its not used for fuel delivery doesnt mean it does nothing. its there for a reason.

The following tables use the map sensor

Main Spark Advance vs rpm vs map
Extended spark advance vs rpm vs map
Spark Correction vs map vs coolant temp
max knock retard vs map (not in pe)
Low octane knock retard multiplier vs map
Open loop AFR vs coolant temp vs MAP
BLM Cell MAP boundaries

And this list is nowhere near complete
not to mention the EGR stuff, DFCO stuff several WOT related things (can only go WOT over a certain map value).
Just because you don't understand why its there doesnt mean its there for nothing

Lmao. I should have went by my gut feeling from your first post and realized it was written out of pure ignorance.

Enjoy your 13 second godly 96, I'll be waving from my 93

Mine is stock cubes/batchfire/SD...wanna run?? Bring your wallet, my gas mileage is garbage and I wouldnt want to waste my time - but that must just be from that outdated batch fire, huh?



Back on topic, once again - if anything his car is strong for its mods. The M6 guys insulting can enjoy their dyno numbers while he enjoys his timeslips, and then we can all be happy old LT1 guys

you guys are ******* retarded. Im just saying sequential injection and MAF has better more efficent readings than SD.

pull your head out of your ***.

my 88 f150 is SD. thing runs fine.

nice 1/8th of a mile... whoop-deee dooo. I guess it really runs shitty so it wouldnt make it down the whole drag. lawl

If sequential and MAF is so much "better", and a godsend over us poor 93 guys, then why do many of the big power guys switch to old school MAFless SD tunes, and why is batch fire is used at WOT? Maybe because, powerwise, they dont mean dick? You have already shown your knowledge of LT1s - almost none. At least you managed to install your Strut Bar without blowing up your engine. Paired with that Sequential Injection you must be 10s now .

thats right, i know nothing about LT1s, thats why ive helped plenty of people fix their cars.

You just come in randomly and start ****. Did i say sequential made like 30000 more HP? no, i just said overall its better.

once again,

btw, im sure his car made it down the quarter, but no one gives a **** about the 1/8th of a mile time.

93 was speed density (ew), bank injection (double ew), i believe a non-electronic controlled a4 as well.. and higher gearing in the rear?

93s are like the redheaded stepchild of the 4th gens IMO.

notice IMO means OPINION. i THINK the 93s were the redheaded stepchild cause they had no vented opti, believe they had the airpump in a diff spot as well, id have to look at my dads 93 t/a.

Like i said, this thread was fine till you started ****. so just leave the thread kthnx.

and hence, SARCASM on the mustang dyno. (the face unless youre too ******* dense)

People go to speed density because they outflow the maf above 4000 rpm. the map can only read so much air. maf is more efficient that is why its better. no power advantage. why spend 300-400 hundred dollars on a new maf when you can tune speed density. I would onlu go sd if you were over 500 whp. other than that the maf rules....

Oh I also would never own a 93, just like I would never own a 97 gtp/regal. The first production model year of any vehicle is never the best. They always have oddball **** that is addressed/fixed in later years.. My opinion is based on a daily driver/ mild street car. If its for drag purpose then who gives a **** your just beating the **** out of it anyways.
