Power Loss On Downshifts, Bouncing Idle And Slight Hesitation At Specific Rev Point -R34Gtt

Wow is that you? Lol

Adjusted my cas to 20degs base timing with TPS connected- see how it drives tomorrow.

And now the bolts in the centre of the slider holes as it was before

I can't believe you haven't specified in that sentence s what timing the power fc was displaying! (Actually I can believe it)

[wolverine]

I strongly doubt Unigroup set your base timing at 20 deg.

[rondofj]

Me too. But thats where the cas was before, and also when I did the belt early this year thats where I set it at 15 but had Nistune. Remember this is 20degs now with TPS connected as suggested by some of you this morning (since power fc). TPS disconnected reads 25ish.

Funny thing when I disconnected TPS then reconnected with engine running it went to 15 instead of 20. Then turn engine off, tighten nuts, then engine on and it went back to 20. Very sensitive to even slight taps of rotation.

Isn't this why some tuners turn the CAS all the way advanced or retarded and then compensate for it in the ECU? So people can't just spin it willy-nilly and adjust the timing?

[Ben C34]

Seriously? Do you not get it yet?

What the power fc says it is putting out at idle is what the cas should be set at. You need to check that.

No way slightly tapping the cas or doing up the bolts moves it by 5 degrees. Unless you are totally ham fisted. It's the power fc putting out different timing. Not the cas moving. Unless ofcourse you are completely undoing all the cas bolts while adjusting them which is just bad practice .

This thread us unreal. Just the recap you aren't bothered with the one initial problem in the the thread only because you caused another more serious issue.....

Who knows. But the amount of guys doing random shit with the hand controllers is surely concerning to them. Now I know why tuners lock their tunes.

FFS Ronald a month later and 18 pages of nonsense! Give up and get the car to some kent who knows what he's doing!

I know/understand you're a tight kent & can also understand that you are trying to learn/troubleshoot on your ride but the money you have lost in bad fuel economy probably could have paid to have had your car sorted by now!

thats what i'd call lazy tuning.... 'edit' took the wrong quote....meant to respond to this one. Isn't this why some tuners turn the CAS all the way advanced or retarded and then compensate for it in the ECU? So people can't just spin it willy-nilly and adjust the timing?

You seriously sound like your on your monthly periods sometimes..while other times you can be helpful,...I have seen your posts on other threads..and seen others give you a bit of a rub-down...

Lol....and life goes on. Let me play with my car and you play with yours right? If you can help then you can be sure its appreciated, if you start having your periods then I might just ignore ;-

I think he is trying to be helpful by stopping you from blowing up your engine.

Mick I dont really care about the bad economy as long as I'm learning stuff and am able to fix it myself sometime, that is highly satisfactory to me. Even if it goes backwards n costs more in the long run. Part of the fun is learning, DIYs, fixing, enjoying, for me that is. Does that still make me a tight kent??

Calm down champ. Read back over what I have written, if you have the time.

This thread is really interesting and gets funnier as it goes on. Any moment now you are likely to pop your engine..

You say you want to learn about your car and buy tools etc, but won't buy a wideband and datalog it which is mandatory if you want to actually achieve anything rather than just taking wild guesses.

Remember the part where I said if your afm is dodgy your car is tuned for it? Do you get what I mean by that? If you did actually try someone else's afm you could very well kill your engine if not monitoring afr's.

Anyway man, keep this thread alive. Its interesting to See how long untill you either fix the actual issue or kill the engine.

Well I hope persistence pays off for ya son before you pull the pin and throw the grenade on that 25

This is exactly why I do not have a hand controller for my PFC

[rondofj]

Im glad I do have the controller- learnt a lot of stuff- if it blows then it blows, its not a Porsche, another 3-5k will have an RB25/30 sitting under the hood with a whole lot of lifetime knowledge n experience : win
