626 manifold quetsion....yet another thread

[hotrodf1]

wouldn't a "boost sensor" be a MAP sensor....just another name?

If you were to look up the "boost control solenoid" part # it should just be a vacuum line.

Wonder why it has the EGR in the name. What would EGR have to do with absolute manifold pressure?

in the manual there, the sensor has three wires coming out of it, and the specs to test it are there - I'm pretty certain it IS the MAP sensor with another name like msp35 said.

hmm, could be....i guess the ecu uses this sensor to sense when to open the egr valve so that it isn't open why on open thorttle?

The ECU uses this sensor to adjust timing and fuel needs, because it tells the computer basically how much of a "load" the motor has on it. Vacuum is a great way to see what the load on the engine is like when datalogging and such.

you learn something new every day!

Subbing, very interested in this cold bogging problem you guys are having. Is anyone using a different manifold and doesn't have this problem? I'm probably still going to put my mani on though, I guess we'll see if it gets me too.

like i said i have been expeirencing this problem before i installed my intake mani

 

[Lodivigo]

Then maybe it's something other than the IM causing the problem. Maybe it's the tuning, too many mods for the stock crappy tune? Are you guys running anykind of EMS?


Edit: Nevermind, I just saw that Alejo has an eManage, tune that sucker and see if you still bog then.

 

[Alejo_NIN]

ok, i used to have this even before emanage.
also, i never had this with the stock intake mani
and also, never happened when i removed the VICS or vTCS so those are not to blame...

i'm thinking it has to do with EGR.
before i used to have an egr pipe that was slighty bent so probably air was being restricted, now i don't have an egr pipe at, just a filter that ovbiously allows more air to get in when the eGR is activated, like at idle, when gases recirculate the most.

now, go figure it!

I wonder if I will be able to tap that wire (perhaps by the ECU harness) to use for MAP sensor logging on my LM-1. How would I go about finding out what pin the MAP sensor wire is on the ECU connector?

Find the pin out for the ECU connector
or get the wiring diagram

 

[Alejo_NIN]

i'm sorry, i just don't think that's a real map sensor....

 

[Alejo_NIN]

ok, here's what we are looking at:

 

[Alejo_NIN]

weird enough, i take what i said...
it does look alot like a map sensor...but how many bars?

the part number is this:
E1T10372
and a quick google showed this:

[Alejo_NIN]

you guys are welcome!!!

lol

sorry for so many continued posts

 

[hotrodf1]

Or Junkyard. $15 you pull it.

woohooo!


i guess it would be easy enough for me to try it.

I would think the sensor would be the 1 bar version. No reason for the 3 bar style (is that only Gm anyway??)

 

[Alejo_NIN]

how many bars is hard to tell
guess there should be a way of testing that

i'm gonna try hooking it up to my emanage and see if it likes it.

that will be interesting i bet. might make it more street friendly - or perhaps better fuel mileage?

 

[Alejo_NIN]

to tell you the turht, it would make no difference since they're both map sensors
