What is different about the 95 n/a MAP sensor, to make it where I didn't need Missing link or anything of the sort?

Gah! Don't test me this late at night! I should be doing homework!

I believe it has something to do with the 95s having their own FPR on the end of the fuel rail. Not 100% sure, but I bet it's related. I've got a 97 and the 2GNTs we've boosted here in az2gnt are 96, 96, 98, and 99. I don't even know what/why there was that secondary pulsed injection crap from the header to the intake on some cars. 95 was the year I graduated from high school.

To better understand the pre-96 fuel system requirements, you might do some searching and see what you come up with. Please share it so the rest of us can go, "Oh yeah. I guess that makes sense after all!"

All 2G's are OBD2.

Not true. Early made 95's were obd1.

 

[DSMcrazy3]

I thought none were OBD1?(not calling you a liar) but I read somewhere that all 2gs had more sensors and what not than OBD1 normally required, while still having less that OBD2?

Yeah but the whole reasons the 95's and the early 96's have so many things diferent when it comes to wiring is because those early 2g's were still using obd1.

 

[SnoopySLR]

are you sure about the 96's? Cause I've seen 95's that have OBD2, I forgot what the manufacture date was for those, but they were built late.

Electrical - Not as common, but there is something called a "voltage clamp" that you connect to the signal line of the MAP sensor which prevents it from sending any signals to the ECU which are above/below that which tells the ECU there is positive manifold pressure. Does the same thing as the missing link, but the ML is much more common due to it's no brainer plug and play configuration. </quote>


Don't you use a 5 volt Zener Diode on the map wire to the ecu to limit the voltage to 5 so the Ecu won't read over 5.


I know its that way on my 00 subaru I need to get one to turbo my car cuz its MAP as well...

So you're telling me MY 1995 RS that came off the production line in 94 is OBD2 huh...that's news to me

 

[DSMcrazy3]

Just check under your driver side dash, on the right if there is a OBD2 scan tool connector, you are a version of OBD2, if you do not have that connector, you must be OBD1

Also, the OBD1 computer looks totally different under the hood. I think there is 2 actually... but not possitive

I think they are one and the same. I've not had a great deal of experience actually using the voltage clamp method (none, actually), but I'm pretty sure the diode "clamps" the voltage down at a set value, thus a voltage clamp. :shrug

Missing link is what I'd use if I needed one.

incorrecto. All 2G DSM's are obd2.

I have an early 95, fwiw.

Also of note is that 95 Neons were OBDII...and you N/T guys have their engine.

so you're trying to tell us that actually own and drive OBD1 models, that they didn't make them You do know that there's more than one model neon too...and no we dont' have the same engine as all of them WTF Please help me out here, I may just be out of the loop or something, cuz I know I'm not always right. I believe we have some OBD2 materials/equipment or what not, but are not fully OBD2 compliant.

EDIT: I'm not the bad guy here...it's just crazy that you're telling us this, yet you don't have the same model, and it's news to all of us

Please note which forum you are in. So far every guy who said all 2g's are OBD2 have been 4g63 guys. I'm not sure about the 4G63 enigine cars, but early made 95 N/T cars had OBD1.

Technically, all 2GNTs are OBD2, but officially, some of the 95s were ODB1. (See below.)

It is all OBD2. It just does not test 100% of the OBD2 parameters.

Before I answer this - here is some background material.

Ok. The 95 isn't really ODB2, it's said to be ODB1. But the important part to remember is that it is ODB2 for all intensive purposes. It uses an ODB2 port, and an ODB2 protocol. You can use any ODB2 compatible datalogger to access it. You can access all of the variables and you can clear the codes with an ODB2 datalogger, just like it was an ODB2 car. The only difference is that it is not fully ODB2 compliant.

Here's an example of the kind of differences. The EGR flow monitor is REQUIRED by the ODB2 standards. It is a test that purposefully removes EGR flow while checking the short term fuel trim for a reaction. The a/f ratio should go lean if the EGR system was actually flowing exhaust gas while it was on(right before the start of this test). If it doesn't then the PCM throws a code. This is why ODB2 people get a CEL when they block of the EGR system. From what I gather - the 95 models don't perform this particular test, so we never get this particular CEL.

It seems like the 95 "ODB1" computer does perform most of the other emission related tests.

So basically it looks and feels like ODB2 but "officially" it is not.

I'm 95 w/ 420a motor and I have an ODBII connector under my dash that hooks up to all ODBII equipment ....
