OK, I searched on this and there is a lot of information but i don't see any straight answers. If somebody can direct me to an existing thread that I missed thanks (and sorry). BUT...

I have had idle issues. I did a boost leak test, checked ICS, checked plugs, checked connections, and set the BISS the correct way and reset the ECU. A few years ago I removed all the honeycomb from my mas (I didn't know it was looked down upon at the time). Just for the heck of it (I read it somewhere), I unplugged the connector from the mas while the car was idling and I have NEVER seen it idle so well. Bad mas? Missing honeycomb? :laser:

Thanks in advance!

I have all but the large center honeycomb removed from my MAS and it idles a little rough at times. If you removed the large center honeycomb then you need to put it back.

I also found that backing out the tps a little helped with the rough idle.

If it's to annoying then just get a GM MAF and translator for better flow.

okie dokie...so this would explain why i have been getting 27.2 mpg for over a year and nobody else gets that? LOL. So theoretically:laser: if I were to get a MAS with everything intact, this would solve my problem (assuming its the honeycomb)?

Also, if I were to switch to a gm maf...do I need any supporting mods or can I just stick it on? I don't know anything about those except what i see in some threads.

FULL THROTTLE SPEED - Item Description Page

I'm runing 510cc injectors and GM MAF. Works beautifully. Idles wonderfully. You can additionally get S-AFC or something similar to fine-tune (people making lots of power do that usually). You'll need a cone filter that fits on the ohter end of MAF. I'm using only MAFT, no AFC.

Please don't buy a used MAF. You can get a brand new one under $100. I don't remember where I bought mine. I may have gotten it here: Parts.com - For every part of your life

There's a list of GM cars floating around here which have the compatible MAF (list is huge, varies from family sedans to Impala SS). Seems many people are using used MAF from salvage yards and have no problems. I personally would use a brand new one, with warranty.

Get the part number and go shopping or go to a salavage yard, get dirty and save some money.

Ok it's fixed:

I found another MAS and stuck it on (with lower and upper honeycomb) and no more problems.

Now I need to go get a gm maft:thumb:

thanks for all the help.

I have a GM MAFT setup, but do not recommend it if you have a small turbo, it's IMO a waste of time and money.


Now anything over say 48lb/min yea start looking at a GM MAFT setup, but keep in mind since theres no temp sensor the ECU assums the temp is hmmm i forget if it's 70 or 80* without checking. anyway it assumes it's X temp and thats it. So to keep your tune in check you have to adjust it with the seasons... That being said it's not all THAT bad, some people make it sound like it's horrible. I don't think so but whatever maybe some had worse experiences than me, I do live in the south. IMO a 2G MAF is the way to go. I myself am "down grading" if you want to call it that to a 2G MAF when I get back state side. Less calibrating to do and I dont have to change my tune 4+ times a year.

79*

You can just get a GM IAT sensor and read your temps. Pretty cheap and easy to install and log through DSMlink, if you have it.



Does the ECU see the temp then and make adjustments automatically? Or are you saying it just makes it easy to adjust yourself then. Cause I did a little reading on adding a MAP sensor a long time ago and thats all people were using it for was to make adjustments easier.

If it's just to make it easier to change the tune then... I still really dont care. I don't want to HAVE to change it all the time. BUT if the ECU can then see that and make the corrections then #### it, i'll keep the MAFT! :sneaky: Thing is a bi*** to get calibrated though. Never hardly got started on mine before I had to leave for Iraq...again! That is another story though.




*EDIT* Never mind, I just found a thread on the link site about it. They said the IAT sensor could not be used for ECU calculations... so poo. :( I really like the MAFT setup, I am just already sick of trying to get it calibrated right, and I haven't even really got far into it! :/ damn it, oh well.

Both the IAT and MAP sensors are just for the user - the ECU doesn't do anything with them. A MAP sensor would be more useful over an IAT sensor.

If you go with a 3.75" GM MAF, it has a built-in IAT sensor. I'm not exactly sure how it works, but I'm willing to bet it will automatically make adjustments, just as a stock MAS would.

Really......Must investigate this. As that WOULD be a solution, however i'm not holding my breath. My luck it just lets you know the IAT and doesn't use it to make adjustments.













Thank you!
