5sfte map sensor issue, tech help Options

[94silverbullet]

I'm trying to get my car on the road again. I have already installed the turbo, exhaust, A/F ratio and boost gauge, helicore ignition wires, oil line, FM inthercoolerand piping, and new plugs gapped to .030.
Things to do:
7mge injector-will arrive tomorrow
MSD 6 BTM- tach harnes adjuster is on the way
2 Bar Map Sensor!
I have been trying to get a 2 bar map sensor installed, but the PN in the sticky is invalid according to the dealership I asked; "2 bar MAP sensor(part# 84420-17030)". I asked about the MAP Sensor for the turbo 93 celicas and he said he cannot look them up without a VIN. I called back a couple of times and had no luck gettin it from the dealership.
So I was on another forum that told me the GM 2 bar map sensor would work.
It doesnt. My car will go to idle but if you touch the gas at all the car trys to stall.
The car ran to the point were I could rev and was only an issue at high rpms or WOT before I had the GM 2 bar MAP sensor.

How can I get the correct 2 bar map sensor that my ecu can understand?

Sooooo tell me that the sticky has the F****ing part number posted as 84420-17030 and is supposed to be 89420-17030... that just made my life so difficulft. can anyone confirm that part number for me thanks guys

its very easy to find one, if you follow the sticky i wrote, and go to alltrac.net or mr2oc.com and look for one in the for sale section.

you dont wanna buy one new, they are ~300$ new iirc.

okay thanks.
since you seem like the go to guy, I was wondering if you have the msd 6 btm, and what you used for your ecu? e-manage or the A'pexi S-AFC 1 or 2?
and does the greddy e-mange need obd II cuz I have a 94 which is obd I.
What should I do computer wise in your opinion?

[Smaay]

thats an itiot parts guy you have. just tell them you want a MAP sensor for a 91 MR2 turbo. if he/she has any competience they can find the part

[presure2]

okay thanks.

i am using stock ignition components.

i started with an SAFCII, learned on that for a long time, then upgraded to the emanage ultimate. it does work with 94-95 cars.

totally agree, the parts guy was mentally handicapped. Thanks for the computer help bro

"It doesnt. My car will go to idle but if you touch the gas at all the car trys to stall."

sounds like you need it tuned right

[94silverbullet]

so you think that when the toyota 2 bar map sensor, and the injectors (7mge) are in, it wont run with out a tune? that would mean that the burein toyota kits also required a tune, so I don't think you're correct
or are you saying it won't need the tune after the new 2 bar and injectors, but would if I don't install them and run the gm 2 bar without injectors

[Batman722]

haha

if you put in a turbo, bigger injectors, a 2 bar map sensor, ect YOU WILL NEED TO TUNE IT ! even the buren kit requires some sore of tuning to make it run correctly.

will it run ? yes, but it will run BAD without tuning it some way.

also, there are 2 part #s for the MAP sensor, one is from an all-trac and the other is from an MR2. They both work the same.

I have to ask, why in the name of Dustin would you think that you wouldn't need to tune it ?

[Theshanon]

dude i donno bout in new york but i would recommend searching for a used one from if not here, then from www.mr2oc.com, i found my 3 bar there with no problem for 180$ as opposed to the dealer qouting me 1,400$ for a brand new 2 bar map sensor. And yes that is correct 1,400$ and for a new 2ndgen 3s motor its 24,000$ WTF?!?!?!?! hahah its messed up

[94silverbullet]

I have read just about every post I can find and I cant find how you guys wired the emanage ultimate. I have the 440cc from the supra and Obviously it runs worse than the 315's b/c its not tuned. I need to install the emanageultimate and have it in drivable conitoins on the sunday after thanks giving which leaves me almost no time.
I need to buy the emanage ultimate (I have a site to buy that)
Buy the harness (cant find that because the link in one of the posts doesnt work anymore)
Wire it up (diagram help? I already have the A/F ratio gauge installed)
bring it to a shop to tune it for me (because I have no clue hoe to do it)
Do you guys think if for some reason I cant get it the emanage in and the car tuned that I would still be able to drive it on the highway? Its a 200 mile trip???
I know we have alot of differences with the timing around 4450, and I cant find any places that have race gas so I just get 93 pump and put an octane booster in
what do you think???

(PS I did injectors, but I didnt get the 255lph walbro yet)

please respond asap guys

Thanks again

Basically I need it to run well enough to live for a year. I know the safc 2 is crude but my car needs to be on the road as soon as I can get it there. Is the safc 2 right under these circumstances?

yes but boosting on the stock fuel pump will get you a blown motor in a hurry

[94silverbullet]

okay, I'll make sure the 255lph walbro GSS-342 is in before I hit the road.
Before you switched to the emanage ultimate did you by chance have any rough setting (A/F ratio setting wise) that I could use to get a good start?
It seems like all safc stuff was on n/a cars but you had yours in before you upgraded to the ultimate right? I just want to get it to survive until Christmas when I can actually have time to play with it and optimize settings for performance.
I definitely rushed into this, big mistake

i used it for 2+ yrs and shannons car makes 285whp with it.

as for settings no,i dont remember what mine were, but i can tell you if you use the 460 rx7 injectors, like you should be, you will be pulling lots of fuel out.

[94silverbullet]

I'm using the 440cc supra injectors. those should be fine..? thanks manny

[94silverbullet]

so trying to find the safc for cheap... Is this what i'm looking for? would I need any thing else parts wise or instruction wise?
safc 2 on ebay (click here pressure? please)
