[slimdigits]

Damn sweet dude!!! On be half of everyone.. THANKS!

[Eko Ramadan]

thats write is as simple as it gets, its not any harder then hooking up a safc or vpc. Now i just have to order mine...errr where is my tax return????? MAKE THIS A STICKY!

[born2drv]

awesome write up! only critique is that 2 of the pictures are the same. but thank you again for taking the time to put it all together in one neat little thread.

i'll be getting a maft-pro eventually, need a reliable engine first ... :bigthumb:

[pimptrizkit]

dope.


i didn;t know you had to cut the ks wire, i'll go ahead and do that.

maybe splice the yellow one in.. i dunno..

but the grey wire that comes off the 10 pin does that go any where?

i htink i spliced it into my hac wire... did i do bad? btw ..88

[simann]

Friggen awsome!

Thanks so much!

[89jdmsupra]

sorry guyz but which is the KS wire

and thanks for the write-up

[pimptrizkit]

it's the one in the diagram where the green wire is going and blocking some of the letter's.... im not sure where it's from...

[NJsupraA70]

I just updated the pre 89 diagram to include the hac wire. unplug the HAC sensor behind the glovebox

also I added the 89+ hac wiring for 89+






only critique is that 2 of the pictures are the same.


Which pics are the same?

This is just in time! I got mine yesterday and going to install it soon. Thanks!

[BoostFreak]

awsome man +1..wait their is somthing sticky about this thread,.... def will help when I get mine in a few months.

[BoostAddctn]

I'm going give this thread a day or 2 before I move it to the FAQ... aight peace :chicken:

You might want to consider mounting your MAP sensor so the nipple points down. Moisture buildup will ruin the sensor over time.

Yup, I got mine mounted like the 1jz's have theirs mounted :) aight peace :chicken:

[pimptrizkit]

good lil tip, i'll remember that when i mount mine, i figured i would put it on the fire wall

[NJsupraA70]

one last bump

Thanks for the tip! ;)

[slimdigits]

I can't really tell where the sensors are placed.

MAP near the intake mani?
AIT same?
What abuot the boost options?

my maftpro is in the mail and i was wondering how you guys have found the base settings in this write up run on your cars? how much tuning have you done with it since initial install and have any suprises come up at all? Thanks guys, great write up NJsupraA70!

[pimptrizkit]

since i have gotten mine wired up and in the car, for awhile i couldn't tell if the unit was working. but i was having problems keepig the car running (cold) and it was due to improper cps and tps, after fixing those and installing throttle linkage, i had left the maftpro unit plugged in once it finaly was running (on the base set up settings they have you programe in for car, displacement, sensor types, and so on,

i actualy forgot how important that lil unit is to making my car run smooth,

on the 3rd day of testing and driving my car, it occured i wasn't sure how incontroll it was, so i unpluged the ecu side with power off, and started her back up, she ran great again but you step on the gas and it acted like it hit fuel cut , just cuttin and choking about 1krpm shut down and plugged the unit back in, and she ran and reved great, and vented to atomospher with out a problem or hickup.

[rpk2012]

I still do not get the HAC wiring on the 89+.......... I do not see on the diagram where the output and input is for is.......

[rpk2012]

I guess no one knows or?

[BoostAddctn]

You have to send the ECU in to get it modded for the output and input wire, that or open it up and do it yourself... aight peace :chicken:

Hmmm, I ordered my package and everything...

But I didnt order the Wideband Controller...

I just ordered the sensor and lambda cable... is this going to work?

[NJsupraA70]

nope.

[Phyrx]

I bought this:

The LC-1 is a complete wideband controller built in to a sealed cable. It features the same award-winning patented digital measurement principal found in the LM-1, and includes digital input, output, and 2 programmable analog outputs.

Will it not work how I am wanting it too? I STILL need a WB Controller?? Somebody told me to get the one for 199.99 and that is what I got... Ughh

Yes that will work.

[Phyrx]

Well, will I use the MAFT PRO unit to CONTROLL my Wideband? Or how do I do it?? Any idea how to wire it either??

The lump in the middle of the cable is the controller.

Yes, thanks alot!

Now I just have to get around to getting it all done!

:) I cant wait!

[adjuster]

Appears this seems to work well when tuned right.

Where does fuel cut come in, and how well do you guys think it is working? Anyone had some lean conditions when the FC is defeated?

I like the AF closed loop option, and the ability to go MAP/Speed Density v/s using a airflow meter of some kind would be nice too.

Might be time to sell my complete Greddy Eman/E01 setup and change over to the Maft Pro.

.

I have not experienced fuel cut yet(but only done 15 psi), I know Mike Malloy has done about 25 psi and has not hit fuel cut.

As far as lean conditions go I have not experienced any, but that may be due to the fact that I am using the afr tracking. With the 15psi I have been running my a/f's stay between 11.5-12.0 under wot depending what gear I am in. So yes so far so good...

[spoolint78]

is it compatible with the fjo wideband?

[Boostedmkiii]

wow, i dont even have an MAFTPro, but i can tell you right now that helped me better understand the ecu harness/wires

great write up man!

[ATLPD3147]

i installed the maftpro into my vehicle today and it started right up but started stumbling. i got a code 24 and 32 which are air temp and air flow meter signal issues.. anyone had something simular and found the problem and fixed it? i checked to wiring and it looks solid..

[ATLPD3147]

on the #6 wire in the install instructions whenit says splice the brown wire into the ecu side of the stock harness what are u telling us to do exactly.. i read it means cutting the THA wire in half and attaching the brown wire to the end that is going to the ecu.. is that correct? someone anyone please tell me something.. thanks :)

[ATLPD3147]

anyone?

[NJsupraA70]

correct

[ATLPD3147]

Correct what?

[NJsupraA70]

Correct what?



cut the THA wire in half and attach the brown wire to the end that is going to the ecu.. is that correct?

:doh: :chairshot I give up! LOL..

[ATLPD3147]

Ok .. Thanks..

[pimptrizkit]

did those codes go away?

i forgot to clip mine aswell and i had those codes..

any other wires i need to clip?

i think i remember cutting the wire for the hvac that sound right?

[ATLPD3147]

I was chatting with supralover for the past few days and he suggested that I place a 2.2k ohm resistor between the THA point and the brown wire off the main harness of the maftpro and it seemed to make the car run so much better. I was able to get rid of code 24 which was the intake air sensor signal. Im still getting code 32 which is the hac signal. I will need to look into that code in the next few days. Seems like the maftpro is leaning toward another satisfied user.. I will keep all yall up to speed on my progress. Thanks again supralover and the rest of yall that help thus far.

[prsrcokr]

Would the purple wire from the secondary harness need to be connected to VF even for AFC mode?
Should F-in mode be on 1 for AFC mode? (this write up was for speed density so I'm wondering what the differences would be for AFC mode and referencing a Map sensor. (Without IAT initially)

[prsrcokr]

She won't run, I followed the wiring with the exception of the purple on the secondary harness to Vf (just using as AFC at first)

Is there a different setup for running AFC only, I've followed the manual and have the settings per the "quick setup for mk3."
I ran Green from KS to ecu and yellow from KS to MAFT. I have the THA wire tapped (not cut) wouldn't you need a wire to each end of the THA lead?
Gray is to HAC (tapped) and HAC is unplugged.

[ATLPD3147]

1st off check for codes

[prsrcokr]

Ok, yeah. 24, 32, 51 is what I'm seeing.

[prsrcokr]

Ok, looks like the setting has to be 0 and not 4 for AFC mode, it runs now.

The 2.2k resistor mod was a temporary fix that I did way back when it was originally installed. That little trick was originally suggested to me by Bob. Whether you run the resistor or not will not change how the car runs. Last time I talked to Bob he said that the new software update should get rid of that problem, but regardless having the code WILL NOT effect how the car runs, so the comment that the "car runs so much better with the resistor" is not possible.

[ATLPD3147]

hmm not possible? u being where u are now and telling me that my car cant be running better after that 2.2k resistor, not thats "not possible.." lol but seriously thats a very strange and unlogical statement there bro. im only telling the community what worked for me and what supralover2000 suggested so yes my friend it "is possible" ;)and for all the guys that might get that code its just something for them to try. you know something just to help the others that might have that code nothing else nothing more. so i dont know where u were going with that last post bro, but just to keep the record straight it worked for me and yes the car is running better for me. no where in my post did i say it was something that every mofo in the community should do. just for the ones that might have that code 24.. so if u wish please clarify why u made it your buisness to say that my comment "car runs so much better with the resistor" is not possble. seems like youre taking that quote and using out of context. i was talking about my car not yours... thank you! :)

[ATLPD3147]

yea its "possible" that the new update to the maftpro might address future issues and thats fine but just to make it clear cause i know how some of you guys on the forums can be i have a unit that after the install gave me a code. and while im on this soapbox i talked to mike the owner of fullthrottle and i pointed out a small issue with the install directions where it concerns the #6 wire. in the instructions it says "splice" where it should say "tap" according to him it was something that they did before some system upgrade which is all good but if youre gonna say tap for the other wires and then cut the KS wires then want the installer to tap #6 theres not reason to use "splice" when the word "tap" was being used for the other "tapped" wires. in other words just keep the instructions clear. thats my only gripe. i think its a great unit and a great addition to the already few additions mkiii owners have. and i will tell all my buddies about the maftpro and how i like it.

[ATLPD3147]

Ok, yeah. 24, 32, 51 is what I'm seeing.
o ok.

[ATLPD3147]

kool

[prsrcokr]

So if one were to switch to speed density, the Karman reading would no longer be used and therefore modifying fuel signal would no longer cause subsequent ignition changes, right? The map would then be seperate or will TCCS still see this as a frequency change and modify timing accordingly?

I read that to monitor timing the yellow wire must be hooked to G2? Does this mean using AFC mode you can not monitor ignition advance? (Since the yellow wire receives input from the KS sensor in AFC mode)

FIRST OF ALL - Please stop post whoring this install thread. You have made a total of 11 replies on this thread that you could of combined into 1. You need to fix that, and stoping adding extra pages to this thread for nothing...Jesus, why not make your own thread instead of ruining this one. This thread was not designed for you to add to your post count. Please read the rules next time.

SECOND - Like I said the resistor mod old OLD news, and is NOT necessary for the install, and based on the fact that the code problem is being addressed in software updates, I dont see the point. If you immediately saw a difference when using the resistor I can tell you that it was either coincidental, due to other wiring issues, or other issues related to your car.. Supralover2000 has a name btw and its Wellington. He happens to be a friend of mine, and is a great asset. He suggested to you to try the resistor because a few months back I TOLD HIM directly that it clears the code 24, BUT there is not difference in how the car ran(and this is based on MY experiments running the car with and without the resistor.)



Im done arguing with you, so save your reply.

[ATLPD3147]

Post whoring ha that's a good one. I was done days ago with my posting and I only started back up cause your ignorant and off the wall comment about you thinking it wasn't "possible". And who cares if I don't know supralover personnally. What he's letting you suck his balls at nite so u feel like u can call him by his 1st name like the fag u are. Ok, good for u. Just don't swallow ;) or he'll never call u back.:) Anyways I was just putting the resistor information for those out there that might come across the code 24 "mr smart ass". For the others that are goona be reading these last few post its a shame that this sort of behind the computer screen bashing has to happen. Like I was saying before, all I wanted to do was share my experience with the other members. Oh well I guess theres always one asshole out there in every community.

[ATLPD3147]

Now im done so "you" can save your reply supralover lover :)

Yep, back to SM for another couple months I go.
If anyone has the timing monitoring info and doesn't mind sharing, please add it to this thread.

Its kind of difficult to have a decent thread when you have incompetent people flooding it with meaningless post after post resorting to 2nd grade behavior. On top of that the moderators do little to correct it.

My information in the first post has been removed from this thread, so If you want the writeup go to SM. Im sure this thread will be closed and removed from "faq" status shortly

As much as I appreciated what you have done to for this writeup, but since the information is gone, i'm going have to close this thread and remove it... thanks anyways... aight peace :chicken:
