stand by what I said. Unfortunately t2te50 you've opened your mouth about engines and components that you aren't familiar with. I'd suggest reading a few technical articles, and also perhaps checking out the 'POWERBUILDING' range of DVD's you can get from Rockets. They cover all aspects of engine design, especially relating to performance applications.

Thanks for the belittleing, but I'm already a qualified mechanic rebuilt many motors + gearboxes and really don't need your STREET MACHINE BULL DUST.

Out in the 'REAL WORLD' things are a whole lot different! By the way running an idle around 1000-1200 rpm is crap! If you fellas call that driveability well god help you!

I may have skimmed over it, but what is the arguing for?
Car makes good power, owner is happy, beef is what exactly?
Let it sliiiiiide.

Congrats on the good result Jeff, I look forward to seeing where it peaks as well.
Have some fun with it!!

Cheers,
Jared

Yep, I think I will lose the 2031 when I stroke it.
The convertor is also playing havoc on the dyno but the 347 should have enough torque to punch through.

You're amusing.

OK to make you happy your absolutely right. I'm a street machine mechanic... I love pretty pictures of engines and love dreaming up combos for people that I have no idea how to build.

Who's got an idle that high? Mine idles at 790rpm quite comfortably, you must have the wrong thread mate.

I have no idea what all the beef is about mate, cant control what someone else does in your thread unfortunately.

Cheers for that mate, im thinking it will peak somewhere around 5500 and hopefully pull another 10hp. Will be looking at modifying the air intake aswell, still running std snorkle, box and piping.

And dont worry i have been having fun with it, such a pleasure to drive.

Yeah terry mentioned something about the morestall you are running playing up.
Look forward to seeing the 347 up n running, personally i'm pretty happy with mine at the moment, but you always get used to the power.
You must be pretty happy with it now yeah? Performance wise.

Results of dyno runs.
Idle is still an issue with 2031 cam.

Very nice results mate, always bit harder to get the power through the auto box. Popped in to BPT yesterday and Terry advised of your results.
Funny that the idle is still an issue with your cam, i thought mine would have been abit worse with my 110 LSA compared to the 112 on yours.


I had a chat to Leon about this as well, his opinion is its due to the speed (or lack thereof) of the EEC-IV ecu, literally it can't see and adjust to what the engine is doing fast enough.


Nope this is not correct, the EECIV is actually quite fast due to it's unique method of calculation. This car just needs to have it's t-body airflow and idle air functions recalibrated. BTW my cleveland ran a massive cam by comparison; 230 @ .050" and .612" lift 110LSA and I had no trouble dialing the idle in with the tweecer.

Thanks for the clarification there Pete. :)

Is the tweecer software difficult to use xr9ute? Can any 'joe blow' learn to adjust fuel trim/ignition maps etc? Thinking of purchasing a laptop and suitable USB....... but like most scared of the unknown.

Seeing that your the resident gun in this field your opinion would be valuable to many wanting to take the next step.

Well Ive sold many tweecers to people who admit they haven't a clue and they appear to be able to get good results. It is quite complex but powerful OEM controls are. EB-ED for example have around 20 3D maps and about 70 2D maps and hundreds of Scalars(switch functions) and while that may sound scary you can get away with touching only about ten of these maps and similar amounts of scalars.
The funniest question I get is "who can tune it in my state?". I say funny because the people who say they can't or won't tune it also have SCT software. So the answer is; forget about what's attached to the EEC...all your doing is unlocking the EEC. The question should be "do you or are you willing to understand Ford code?"

Pete.

Hey Pete,
Not sure if Terry has already gotten onto you regarding this. But about the speed limiter, Terry couldnt seem to find this function on the TwEECer. Is it possible to bump up the speed limiter using the TwEECer, as i take you have read previous pages here telling why it was cuttin out at 5000rpm on the dyno preventing us from reaching peak power.

Jeff

if you remove the speed limiter, you know you run the risk of the tailshaft coming to grief...

Yeah mate, well aware of that. Will carefully increase it if we can in 5-10km/h incriments untll we reach peak power. Hopefully wont have to take it much past 190km/h.
