did some investigating on 90mm tb and titan wire harness for tb

[Toomnymods]

Well i went digging thru online manuals for the titan and chevy and found this intresting bit of info, dunno if it will help anyone or not, but that is what this forum is about sharing info and not hiding it from others.. lets get to the bottom of this and start making pgm's again.. all thatshould be needed are a few POT's or potentiometers to vary the voltage from the gm tb to the nissan wireloom that way the ecu doesnt freak out. we used to work with these in a/c refrigeration but im sure someone out there is a electrician that knows more than i do..


90MM LS2 Throttle body will work with the following information

PIN ID LS2 90mm
A.) ACT2
B.) ACT1
C.) +5v TPS Reference – Common to both TPS’s
D.) TP1 Signal 0-5v
E.) Common Ground
F.) TP2 Signal 5-0v
Pin connector Part number: 88988106

Titan pin colors /functions

Terminal # wire color Item Condition Data DC Voltage
47 Y Sensor power supply [Ignition switch: ON] Approximately 5V
(Throttle position sensor)


50 B Throttle Position Sensor 1 [Ignition switch: ON] More than 0.36V
_ Engine: Stopped
_ Selector lever: D
_ Accelerator pedal: Fully released

[Ignition switch: ON] Less than 4.75V
_ Engine: Stopped
_ Selector lever: D
_ Accelerator pedal: Fully depressed

66 R Sensor Ground [Engine is running] Approximately 0V
(Throttle Position Sensor) _ Warm-up condition
_ Idle speed
69 W Throttle position sensor 2 [Ignition switch: ON] Less than 4.75V
_ Engine: Stopped

Cool Info.

Great Info! I wish i was an electrician!

some guys in a electronics forums asked me for reading with a Oscilloscope, Iddle to WOT scopes an a titan and a chevy vette.

[gweasel77]

Heck yea man! We'll get it figured out one way or the other!

Maybe Jared, the OP from this kicka$$ thread might be of some assistance.

Subscribing for some genius to figure this out so I can buy one Thanks TMNYMODS!

A guy that works for me is an electrical hackjob. Known him since we were little and he was always tinkering with random crap. I emailed him this thread and a few other PGM related ones to see what he thinks. I don't think he would take the project on, but he would be useful for insight. Another long time friend is a developer for espn fantasy sports and knows pretty much every friggin computer language. Maybe he could be of some assistance on the "getting it to talk japanese" part of the PGM. I'm sure everyone has their wheels turning and this is totally doable with the right people.

For the love of godddd would the PGM creators get on here and offer some insight... maybe point ''us'' in the right direction, preferably NOT the route Relentless has gone..?


How bout this, PGM 90mm make the ''wiring loom/driver/box/translator" and sell it. Then we can buy relentless' 90mm to 70mm adapter, and everyone can buy the Hitachi GM throttle body (part #12602800) that is around $150 bucks.


That way not one company/person has to make a complete 90mm kit, its more of piece it all together and it will work. Instead of a $1000 paperweight that works half the time.

whatever.... i'm talkin out my azz, not that any of the above i said makes sense, let alone will get thru to anyone lol....

how bout lets all agree that the 90mm LS2 TB for the titan is Phucked (aside from PGM owners).

I have tried 3 times to buy the RLRPM TB adapter and have gotten no where with Rich, Each time says he has to get a price from the parts manager and will call back, still have not heard from him.

I can understand being proud of what you've created, but keep it going it or get out of the way progress & let someone else take over. Your holding everybody up from being able to mod! Goodness Graciousness... LOL

[gweasel77]

Maybe Up/Rev told them to keep it to themselves & not to open up another can of worms??? ...or maybe their just too busy to be worried about it???

Who knows, but it doesn't make sense...

If you find someone who can do it I will supply a an ls2 tb for testing : )

UPREV knows how to make this work, they even stated what harness to buy and what Hitachi GM 90mm throttle body to get, they encounted idle surge issues and I think figured it out, they even made VK and VQ adapter plates for like $25 . ALthough this was a few years back.
