Power Fc Dyno Tuning
Just ironing out my engine problems. I got a dyno tune and the car runs mint. I didn't have time to leave it at the shop for cold start tuning and its unavailable where i live.
Mar 09, 2010 Op I'm sure intec or Stefan at advance street performance could tune your power fc. Both of them are in Kent just call them up if your interested. Intec might even be able to dyno tune. If asp will even do it, it would be a street tune.

So I might give it a go.It's also got a slight miss on idle and at low revs. It's real hard to hear but it's sometimes there.Ive got power fc, hand controller, datalogit and wide band.The issue I'm having is the car wouldn't start first pop when it's dead cold. My engine temp never gets colder than 30 cause of my location.
It sometimes took 3 goes.So I had a read up and first things first I took the atmo bov off and smashed it with a hammer! I've blocked the vacume line. The car starts first time now.The issue I have is for the first minit of warming up it has a real flat spot after that it's fineThe engine doesn't want to rev.
Not that I want to bash the limiter or anything.Let's just say my girlfriend wanted to shift my car first thing in the morning, turns the key, lets the clutch go, gives it some gas and it will stall or coughf. Ok for thoes listening, I've got the fueling sorted. Just adjusted the water correction tables.
Was way too rich. Got em 13.5 at 30^deg. It's punchier.I've got this stupid miss fire I can't get rid of.Here's the symptoms.Idle sounds lumpy/smoothAnd when I hold it at 1500 2000 2500 3000 it sounds like a fully sick lumpy cam gtr! (Not the sound I want)Seems to rev ok. Las time I drove it had the miss but boosted 18psi sideways at the track just fine all day!I chucked a new set of plugs in, changed the gap from.8 to 9.3 didn't make a difference.Changed afm to a spare one. Made no difference.Removed bov still nothing.
Starts better tho.I've got a feeling it's the cas but don't want to throw 500 bux at it. I'm over it.What else can I check?02 is newishGot spitfires there newishBand new injectors/pump.

I'll be sure to set the base timing again I'll do that next. Yes I had the cas out because I heard knocking from the cam cover. One of the bearings has collapsed, I some oil in it and put it back in and the knock has gone.Here's the thing about the tune.In had the car on the trailer, drove 2200kms broome to Perth.
Dropped it at the tuners, picked it up. Drove to the race track the next day unloaded it.
Done a drift session.A passenger in the car said to me 'this thing has a miss fire'. I ignored it and continued to drift as it performed well.The next day I drove 2200kms home. (Yes 2200kms). I have never driven the car since.That piss want tuner should have picked up the miss. Does anyone want the shops name?

I just set it to 15 just then. Yeh it was out was on about 18. It seems to get better when it's running at 80degreese. I can only hear it defiantly when I hold it at 3000 in neutral.
There's somthing defiantly there or there abouts. So frustrating.Do you have your tuners contact number for after hours always make sure you have mobile contact so you can text them or what ever - ask him what he set it on when he tuned the car. Remember this base setting will coincide with your ignition map right through the rev range. So if it was 14 below and your tuner has that mapping at 14 and you have it at 15 then the mapping will be out by 1deg which in turn would affect AFR as the fuel mixture has been tuned with the ignition map and fuel map - TPS and MAFAlso did the tuner change the position of the TPS and mark it when he had it set to the correct position - some tuners will just move them into place an extensive tuner will tick all boxes. You could see if it has moved or wasnt done up tight - or check the Closed Throttle and WOT voltage - even just turning the screws on the TPS can cause it to moveAs for your plugs I wouldn't go more than 0.8mmTo save yourself from pulling your hair out and getting frustrated with the car - I would definitely contact this guy and query him on the issue like XGTRX said - ask him what he had it set on - contact this guy and bug the hell out of him until he fixes the issue. Yeh I'll give it a go tommoro although it's tight under there.
I cleaned it 2 years ago only done 500kms should be clean. Dunno about function tho. Gonna clean the spitfires and put dialectiric grease around the boots and clips.
Got rid of the knocking in the front as it came bak. Cambelt was too loose. Gonna put a resister and eliminate the knock sensors aswell. My wiring might have been poor when I put the freddy manifold 2 years ago although it seems to read ok. Gonna check fault codes and also tps volts.

Gonna check fault codes and also tps voltsYeah its the worst place to work on under the manifold and ya have to love those factory hose clamps sometimes.Excellent hope it goes well and we can see some posts when you get the problem sorted.Enjoy your new year. Stupid knocking is back. It's noisy on idle. And up to 2000 revs. Comming from the right hand cam on cylinder 1. It's not the cambelt. What noise does lifters make?
I thought they were more tap tap tap. Mines knock knock knock.Anyways cleaned coils and used dialectic grease to try sort my miss. Dunno if it done anything. Looked like number 4 was a little unburnt so hoping I've cleaned that up.Tps volts were good.When I hold it at 3000 rpm now it fluctuates from 2800-3100 wtf is that? Somthing air related I bet. I just set it to 15 just then.

Now you've just lost some power as your entire map has 3 degrees less timing.still safer than those guys advancing their cas to 15 when it was much lower.Also that fluctuation at 3k rpm could be from a lean spot on the tune that was never tuned on the dyno as the tuner didn't hit that load point or didn't tune cells around certain load points.
