Ok, so I wired in my SAFC into my S1 R33 using this guide:

http://www.skylinesaustralia.com/forums/Sa...3-G-t85232.html

Everything is fine, except the throttle position is all over the place. 99% of time it sits on 0% throttle, and when it does move it is only for a split second, barely long enough to see the numbers change, and it has no relation to me actually touching the throttle. At idle, it will jump around, peak gets to 100% throttle, without me touching anything.

Now, I have triple checked the connection at the ecu, redone it about 6 times now to be sure. I have double checked I have the correct wire according to the guide, except that mine it was blue with a yellow stripe, and the guide says white. Guessing the different colour is due to the guide being for an r32, but the position is still the same.

Does anyone have any ideas on what could be going on? Can anyone with an SAFC in a S1 R33 confirm the colour of the throttle signal wire? Really need to get this sorted ASAP, can imagine with it like this, won't be able to tune because the SAFC won't recognise correct throttle.

Have you touched the settings on the SAFC, because the throttle position was working when i had it.

I think you might have connected the grey wire (Throttle Position) on the wrong wire. I just checked my ecu. It is Red with Black Stripe for Throttle Position. My blue with yellow stripe is Engine Temp Sensor. Which is directly opposite the TPS wire.

Wont have time to check it for a couple of days, but have left the settings as they were. Will check that wire, was going by the guide, will look for that Red/Black wire. Cheers for that, hopefully solves the issue.

    • Oh yeah forgot to also mention need to also unplug the IACV as well. Thanks for the reminder @MBS206 Unplugging the TPS takes it out of closed loop so you're able to screw down the IACV without the ECU trying to add/subtract timing to maintain the idle (not sure PowerFC can even do this, but Nistune and the OEM definitely does)
    • For sale is my 1999 Nissan Skyline R34 GT-T, tuned to 234 kW / 313 hp. I've had the car for a few years as my daily driver. The car is original (as far as Skylines go), with only a few minor upgrades to enhance performance and driving experience, as typical for such a car of its age. Overall, it is in great condition with no body rust, thanks to its earlier import date. It features a top-notch security system (not literally, but it's great!) with remote start and still functional 4-wheel steering via HICAS. It comes with several performance and handling upgrades, including:     Hypergear 450HP Turbocharger running 17 PSI boost, installed mid-2021 by Jaustech     550cc injectors     Nistune ECU     Front-Mount Return-Flow Intercooler     X-Force Stainless Steel Exhaust     Upgraded engine mounts     Bottom end bearings replaced     BC Coilovers     Lenso DR1 rims     Bridgestone Potenza Adrenalin RE003 TL 245/40R18 97W tires, fitted early 2023 The interior is mostly stock, with a few additions:     Viper Satellite Tracking System with remote start     Bluetooth Double-Din Touchscreen Head Unit     Steering wheel cover Cons:     A few paint imperfections here and there     Driver’s seat shows more wear than the others. It's not torn at all, but I've added a seat cover to protect its condition. I also have a CarVX Vehicle History report available for serious buyers, so you don’t need to purchase it yourself. Price: $26,000 ONO.
    • I've had two suzukis in the past have an extremely hard time turning over and not starting after sitting for a few weeks. Ended up the alternator would seize up causing the starter to force. Same issue both times.  Maybe they're sourcing their alternators from the same place...
    • Ah right. Maybe my rb just loves chewing through batteries lol.
    • On the R34 can't you just unplug the IACV? This is the way I've always done it on the R33. Disconnect IACV, get it idling around 650rpm, and then do a power reset on the ECU to get it to relearn idle (factory ECU).   The big reason no one has touched on as to why you'd want to get the base idle right, is that it means the computer needs to make smaller adjustments to get a good idle at 700-750rpm.   Also, cleaning the IACV won't normally make the car suddenly idle lower or higher. The main issue with the IACV gumming up is that the valve sticks. This means the inputs the ECU gives, aren't translating to changes in air flow. This can cause idle choppy ness as the ECU is now needing to give a lot of input to get movement, but then it moves too far, and then has to do the same in reverse, and it can mean the ECU can't catch stalls quickly either.
