Ok first off Ive recently purchased a GM maft setup and I am trying to set it up on my car.
I am not trying to tune with the maft, I have a eprom chip controlling everything so the maf will be zero'd out. I am coming from the 2g mas.
The maf translator that I have is a hack job, because the guy who had it before me was trying to do the cheapo wiring extension to allow it to sit in the glove box but the wiring was so F'ed up with different colors spliced on and no harness plug for the stock maf plug to plug into that I decied not to try to confuse myself with his mess and I just ordered the 2g Maf harness extension from machV http://us.st12.yimg.com/us.st.yimg.com/I/machv_2001_148642152 also so I can sit it in the glove box the right way.
Ok well the black plug in that picture in the link is the side I plugged into my 2g plug harness. ( I have the 2g plug spliced into my 1g harness since I used to run 2g mas.)
Now, I cut off the white plug in the links picture and the 5 wires left hanging from it were identical with the colors of the wires coming out of the maf translator, so i was thinking MachV would just make the wires the same color for simplicity, I just spliced the wires from the cut end of the extension harness onto the Maf-T wires color for color.
The three remaining wires coming out of the translator were attached to the small plug that goes into the GM maf itself. ( A black, a yellow, and pink. ) I didnt do anything with the white wire ( rpm) or purple. I dont believe i will need them even though later on Ill hook up the rpm wire anyways.
Well when I tried to start the car with everything plugged in and setup, the car immediately began idleing funny, hunting up and down from 1k to 3k ( idle suppose to be 900rpms.) and then I smelled fuel, and my check engine light came on seconds later.
My CEL is never on when I just have the 2g mas on there.
My friend Aaron runs a maf in his built 1g and he knows how to tune with them and set it up and everything with the translators dials. The red light flashed when he was trying to set it, and the green light blinked like once when we first tryed to turn it on and then turned off and stayed off ( Not right ?)
The conclusions Ive came up with is-
1.) I completely wired it wrong,
2.) I completely wired it wrong and/or the translator or maf is crap.
So for today I just put the intake pipe and 2g maf back on and just left the gm maf were it was on the UICP and drove it like that to work since I cant have the car down....
So could anyone help me with the wiring, Ive searched thru a few threads and what not on how the wiring is suppose to be and what each color is for, but since my wires were so fudged with no plugs to begin with I dont know which goes to what plug, especially since there are two blacks, and two pinks. I may end up just going thru the process of elimination. I need to keep the MachV extension harness as a bridge as I dont want to cut into my stock mas harness wiring or chop off the plug, so I can make this gm maf setup reversable like I have done in case I dont want to continue with it.
Thanks....
