what happens if i decide to use water/meth injection. How can I compensate for the octane boost/decreased intake temps. The speed density wont be able to pick that up, will it???

[Jeremy C]

The T-Pro has an auxillary switch you can wire to the meth controller. When it activates the T-Pro will switch to a different map that you create.

NICE!!!! Do you have that set up? Is there any hesitation as it is changing maps?

[Rustang Cobra]

i have that setup

it works perfectly!

if my water/meth doesnt turn on for some reason, my car will not boost over 15psi and it'll stay at an 11.7 ratio

if my water/meth does turn on then it raises boost to 18psi and leans out my a/f ration to a 12.1

Bob- you said something a few pages back about the ecu "giving up" and going into closed loop mode at idle. MY stock 02's don't cycle at idle, they stick around .88-.91 and the WBO2 is around 14.7-15.9, it varies. What could be causing this? Also, I used to have a problem where the car would idle with A/F in the 12's no matter what I did on the safc and wouldn't cycle.

Got a few questions, appreciate the help up front:

1) Can someone take a pic of the boost control harness plug so I can see what wires go where? The unit I bought had them disconnected to pass thru the firewall, but didnt reconnect them to the plug. This is a Purple and Pink wire and they are supposed to terminate Somewhere in the 8 pin connection to the right of the serial port (opposite side to the 10 and 6 pin port).

2) On the 10 pin plug there is a Purple and Orange wire, lower right two pins.... the Orange says its for O2 sensor to terminate to the White wire on pin 55 or 56 of the ECU and the Purple says its for sensor ground pin 72 of the ECU. Question is are we supposed to be connecting the orange to the WBO2 signal out rather than the ECU Narrow band sensor? Then, do we want to ground that purple wire to the ECU still or to the WBO2 ground (I would assume ECU due to the other sensor references we are taking, and that using the WBO2 is less important??).


3) Does full throttle offer a open ended Speed density harness (IAT and MAP), I bought the one for the 3s but it was designed to plug into the stock air meter and I really wanted to wire it directly into the ECU but need longer wires to do so.

4) As for the IAT connections, in AFC mode is this just to log the OE IAT sensor temps at the MAS or does the Maft Pro use it for something else? Is this even required for AFC mode?

5) Where are most people getting the +5V/Ground for the Map Sensor, I was thinking of just running it to Pin 61 (+5v for miscellaneous sensors IE. TPS/Baro/IAT) and Pin 72 (Ground for same sensors).


Rustang, it would be really helpful to sketch out the 10 pin and 6 pin connectors on the first page, and show the wires and their respective colors for those installing. Maybe its too difficult to illustrate though....?


Thanks,
Rob

i'm at my gf's place so i cant help too much with pics and illustrations....

1. i'll take the pic and post it later today, if noone else does

2. im personally using a wideband so i have orange and purple wired up to that, but i believe that if you want NB, 55 is probably the front 02, 56 is probably the rear 02, it shouldnt matter whether you ground the purple wire at the ecu, frame or the w/b ground, but id personally ground it at the ECU because thats where the factory 02s end up being grounded to also

3. bob can answer this one, however you can remove the wires from the plugs using a small flatblade screwdriver and then just extend them if you like. why is it that you want the speed density harness if you dont plan to use it?

4. afc mode does not require an IAT and its pretty useless to log it on its own...

5. people are getting 5v/ground for the map at the actual 3bar map sensor, again i dont think its necessary for you to connect these if you plan to run in afc mode

all you need to do is intercept the mass airflow in signal, just leave the factory ecu to deal with IAT and baro as it was designed to

rob, i didnt deem this as necessary like in mellons emanage post because the maftpro harnesses come prebuilt and every wire is listed by color/function in the manual, so it just seemed kind of redundant

i'll take a pic of each of the harnesses and label them in MS paint for you later today

Ya, thats what i was thinking but the wb02 isnt grounded there so its 6 of one half dozen of another??

I am going with AFC initially, then moving over to speed density. Just trying to get it all worked out now, then do a smalll couple things to convert. I paid $40 for this harness but it maybe cheaper/neater to get 2 other harnesses with out excess soldering/etc. If nothing is available I will do that though.

Thats what I thought. But if connected the Maft pro will just send the signal straight thru to the ECU un tampered?

I want to log boost, plus I am going to speed density mode at a later date. This answer doesnt make sense though, I am trying to get power TO the 3 bar map sensor... question is where are people getting the power FROM? Is there connections on the Maft Pro for +5v/ground? If not I will just run it to those ECU leads... unless there is something better.

Right, I am just trying to get it all ready for speed density... but before I hooked up everything I just wanted to make sure the IAT passes directly thru it. The baro I realize is now fixed.

I can respect that.....

1: Pink = 7 Purple=8. 8 is closest to the serial connector, "top" row (closest to 'front' of the unit.


2: Orange is a voltage sensing wire. Purple is a ground sensing wire..... connect the purple to the Wideband unit ground, as close to the wideband unit as practical.

3: Get a "Speed Density Plug-and-Play harness." it runs from the MAP and IAT to the 6 pin plug on the Translator Pro. Then just make a connection from the green wire in this harness to the EGRT input on the ECU if you want boost in your ECU logger. This will allow you to leave your stock MAF plugged in...

4: If you run a separate IAT with the pnp harness you can monitor what your charge temps do.... and you will be ready for Speed Density when the time comes. IAT sensors are cheap.....


5: See #3 above.

As always, Rustang's help has been excellent and is much appreciated.

Ok and 7 (pink) is on the top row too, next to 8?

Cool. I will hook these up to the WBO2 signal AND GRound.

I ordered a PNP harness already, but I guess I got the wrong one as it is designed for the MAS plug. What part # am I looking for, so I can be sure to get the right one tomorrow? Are the leads long enough to make it from the engine bay to the cabin? I probably will be leaving my EGR working, so no using that signal wire. I figure I can just log boost on the Maft Pro correct?

Ok, this confuses me. Does this mean I should order ANOTHER IAT harness, and get a 2nd IAT sensor? Right now I already have a single IAT, and the speed density harness for the MAS plug (which I am going to return for the other PNP harness).

Ok, so the leads from the new PNP harness I get will terminate both the 6 pin on the Maft Pro, that is cool but I dont know where they would connect (dont see it in my directions). 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.....
