Throttle Position Adjuster

So I was having a chat to a mate who is an electronics guru.

I told him how the ecu is programmed to control the throttle of the car, dependant on load and throttle position (the pedal) and explained how i want the throttle open MORE than the ECU is telling it to, by a percentage.

He seems quite interested in doing this and this may improve engine response for us all.

I guess my car will be the guinea pig (lucky i have a spare TB for him to muck around with - and break if needs be) once he has something. I just want to see who else might be interested, and also work out and scenarios this would be bad.

I think during cruise (so an imput while cruise is on to not affect the throttle position), but have nothing else.

Im hoping to make it adjustable, as a percentage of the throttles actual position. ie, 10% more, 20%more. The difference between this and the other kits out there now, is that they affect the TPS (throttle pedal) and not the actual throttle position of the engine like this kit will do.

Any ideas or comments??? this would be V35 and Z33 compatible as well i guess..........

Ian....no idea's for you but I will tell you one thing.

After I put in the Haltech it is even more noticeable how much the fly by wire takes control.....I have way(WAY MORE) more response at 25% to 60% of the throttle than 100%. I am slowly learning to drive it....but its a F$%KING pain in the arse.....bring back cable I say.....bloody engineers :)

I agree, there is so much lag in the throttle, the stepper motor is too slow and wont snap open. +1 Bring back the cable.

I dont know if changing the resistance will do anything but its worth a try.

The throttle is too touchy also I find, its hard to stay on 100 as a tiny bit more pedal and im doing 120, cruise control would help but Ive got so many other things to spend $800 on.

    • that is correct to be more precise, this sensor goes to a loom which contains only the flat blade single terminal (to connected to this sensor) and then the connector shown in my first post. This loom is tied up to one of engine hairness
    • This is really sad news to hear and it has taken me a few days to come to grips with the loss of Neil.  Neil was very straight forward and I have always respected his honesty and how he called it how it was.  He was a very knowledgeable man and was always available to provide advice when you needed help to solve a problem because he would have encountered the same issue in the past and could explain how he solved it.  Neil will be missed by many members of the Skyline family.
    • Dropped the car down to my mates shop on the 19th to get it on the dyno. Ran the motor in and dropped the running in oil and filter and filled it up with some engine oil.  Monday arvo I went down and we got a tune in her. Had a fun time trying to get it to hook up on the rollers. We end up having to roll into the throttle, reaching full throttle at around 6k. Made 23psi on gate then tapered off to 20psi up the top and spat out a healthy 700rwhp.  We had a slight voltage issue which was dropping ecu volts to around 11.8v so we called it quits and on Tuesday I went down and ran a couple of new power feeds to the ECU and DBW relays. Have yet to test it as we were trying to get things sent into the ECU from the TCU over CAN. We've now got oil temp, programme switch and gear position. Still working on gearbox speed, but have been told what to do so hopefully that will sort it. Once we've got speed working, we can start setting up the gear shift cuts and do some clutch adaptations in the TCU.  Should have the majority of it setup this week and go over the tune to see how it is now with the new power wire.  Was slack this time, didnt get any full runs as I was watching the TCU data on the laptop.

    • Not until I googled it, now I remember lol. Seems like it's just to clean it up. But it doesn't stop the leak, I have a leak issue though? Thinking whether I need a new bottle, surely not lol.
