050SDPNP They list only 6 foot, but there is a 9 foot version as well....

Not sure where the confusion happened, but they probably assumed 3000GT/Stealth always get the 3S specific harness. If you want to run AFC mode, the universal harness is the easiest way.

You have all the IAT's you need. One in the stock MAF, and one that will plug into the speed density harness....

What pins on that 6 pin would they connect to (Map +5v/Grd and IAT Ground)? Looks like the IAT signal (brown) connects to the lower leftmost pin and the Map signal (green) is to the right of that one.... so there are 4 left.....

The universal PNP harness has 6 wires in it. They are (in order) +5, MAP, IAT, Ground, Ground, and Aux. It plugs into the MAP and IAT sensors, and right into the Pro.

not to hijack but maybe i didnt notice it before or maybe its new but the maft pro website has timing control on the homepage...has it been released?

[DriveFast99]

i dont believe so, cuz i am still waiting on it.

also i still have not recieved my password to register. i sent the guy on your website a e-mail and havent recieved anything yet.

[TurboBob]

timing control is is in the works, but not released yet. It will be soon though...

Registrations (the free ones) are a couple step process, Mike collects the info and sends it to the TunerPro software guy (not me). The registration info files are generated and sent back to Mike, then out to the customers......

It'll get there, sorry for the delay.

ok cool thanks bob.

p.s. Cant wait for timing controll

Cool. That universal harness is exactly what I had in mind... 6ft might cut it but I am not going to risk it at this point. I will order the 9ft version in the morning and hope they can credit me for this 3s specific one when they get it back. Its my fault though, I asked for the 3s PNP harness I just didnt really get into if it fit my specific needs or not. It does seem to me that the universal harness can be installed very clean though.

To further clarifty, I am adding colors is this correct? Also are the two Black Ground wires the same reference point, or should one be used for the IAT &/or Map Ground?

1----------[
2----------[MAP sensor
4----------[


3----------[
5----------[IAT sensor


6------------Aux

You have the colors right

The black wires are tied together inside the Pro. They are duplicated for wiring convenience.

Hey Fellas. I need some help Please! I thought my stock maf was bad. purchesed maft pro and still having problems but not nearly as severe. When I WOT the engine acts like its flooding and wideband reads rich up to about 4500 then smooths out and pulls like a raped ape. when it floods, it stutters, loads up but doesn't backfire. If I give it partial throttle it's fine. with stock maf, I could only give it about 20% throttle.Now with maft pro its a lot better but still floods at wot from 0 to 4500. Here's the thing, if I reset the ecm it will pull fine wot,no problems for about the first few minnutes then goes back to flooding, it acts just like the ecm is reseting the fuel maps and it runs in a set mode for a few minnutes before learning and going back bad. I know there is a reset pin for the maf sensor in the ecm. So this being the case I don't see how it could be fuel pressure, could a bad ecm act like this? I'll just list components I think are essential to problem. 97"VR4, I have the walbro fuel pump hotwired, new coil pack, new ngk patinum plugs,new 10mm magnacore wires(ignition system is fine).replaced PTU,TPS sensor.
thanks

do you have a boost gauge?

What do you mean by 'flooding'? Do you mean cutting out?

Do you have a scantool/datalogger to check the O2 sensors and fuel trims?

By flooding I mean gas flooding the cylinders like a carberator that's not adjusted properly. when the suspected flooding occurs, I can smell gas fumes, the wideband o2 runs rich and the car stutters untill it leans out. Too much fuel is like a fire extinguesher. Not a problem usually associated with fuel injection but something is wrong here. Also I can get the car to stable out at 14.5 a/f, but it will not idle or cruise at 14.7 no matter the adjustments. try going leaner than 14.5 it will go from 14-15.2
I do not have a scantool, I do have the PLX R500. I'll try to log it to see if maybe it could be an 02 sensor, although I had checked the voltage on the NB 02's previously and they read normal.
