which 3S MAP Sensor, rev 2 or rev 3 Options

[FunkySR]

hey all.
I am just about to boost my 7a, as many of you know.

Anyway, I have managed to source sensors from the 3S, but what would work or does it not matter. He has both rev 2 and rev 3.


Only posting here because i need to make a quick decision.

Cheers
Jason.

idk but ppl say we need a 3sgte map sensor on are 7afte or your engine will blow, i tuned my emanage with my stock map sensor and the car runs great, but when i put my 3sgte map sensor the car just chokes on air when your giving it throtle.... any one no why?

[rjbibeau]

different signals you have to retune to use the 3s map

rev 3 doesn't have a map i don't think

[FunkySR]

ah ok thanks. I am running a SAFC2, but will use emanage at some point. So I guess I'll go for the rev 2. Also, will it just plug in or do I need the plug as well?

Many thanks.

jus use check valves for the map

[laff09]

This isnt 1991. Check valves should not be on your damn vehicle

[FunkySR]

lol. true that LAFF. I decided to go for the rev 2 sensor. Will it just plug into my harness?

check valves are for fish tanks, not turbo setups.

use the 2 bar map from a rev 2 3s funky, (yes, it is plug and play.) you'll be just fine if you set it up and tune it properly.

ohh i see, then i guess i gota go pick one up too... whats rev 2 , u mean generation 2 3sgte? so from like a 90-93 all-trac or 90-94 mr2 turbo? is that right?

yes.

thanks guys. I will keep yo updated. I'm using a JSGTools manifold kit and T25. Lets see how it goes.

I havent got a wideband in the car, but the workshop does have a rolling road which i used to set up several SAFC2's and Neos. I will later change to emanage. This is just the beginning.

im running 8psi on my stock map sensor, i tune my emanage with it and the car running great. but im a put th 3sgte map sensor to get the most power i can from my engine, but im a have to retune it.i think if you get a good tune you can run with your stock map sensor.

[mikecelica]

i thoguht stock couldnt read boost? it reads -15 to 0. right?

[FunkySR]

correct Mike. It reads vacuum. I think the emanage can manipulate this, though not 100% sure. I'm just gonna do the right thing by fitting a proer MAP sensor.
