i thought that was a sign of a **** poor tuner?

anyhow i believe that aint right,
my engine doesnt idle right so the tuner points fingers to anything but
his tune.

is this practice still going around?

he says he is using HP Tuners!

W T F !
Which tuner told you to drill it? There's better ways to fix your idle.

i have a nelson performance tune
and the tuner told me to drill the throttle blade
to help the idle

he said they use hp tuners
and using that program i wouldve thought there isnt anything that
hp tuners cant fix

it shifts fine but hearing of nelson performance reputation on this site
i figured they would be able to walk all over my set up and have one hell
of a tune
2003 lq9
317 heads
216/220 560/560 cam
3200 stall
cai

i was happier than a 3 peckered billy goat but after 4 days of driving the
tuned ecm im dissappointed in the tune
i have already talked to Ray and told him about my issues and theyre gonna send me another ecm. im not convinced Ray is going to take care of my issues and make me feel like a 3 peckered billy goat.
i have high idle, surgeing at cruise speed, and backfire/popping at 4500rpm
at wot, and it died parking at the parking lot at walmart( throttle tapping)

the stock 5.3 ecm had issues but i think a tuned ecm shouldnt
compare to the stock 5.3 ecm

i was bummed when he suggested to drill the throttle blade because i thought that was "cheating" the tune

The factory drilled holes in some throttle blade. I try not to, but have on some big cam cars with ilde issue. Tuning is the place to start and end. I have even plugged the factory hole to fix idling issue

i refused drilling my throttle body for years. after getting HP tuners and reading alot, i realized that i NEEDED to drill my throttle body. with my tps voltage correct, my IAC just couldnt keep up. after drilling the throttle body, the IAC settled into an acceptable range and the idle tune fell into place.

before letting your tuner drill your throttle body, have him check the tps voltage and IAC counts when hot. if the IAC counts are within 50-80 at hot idle there is no need to drill.

Thanks for the post.
TPS and IAC
If the IAC park is not giving enough flow when the IAC park is at max setting you may need to drill

it keeps high idle letting off the throttle from a cruise of around 45
coming to a stop it wont idle down till it is completely stopped.

cold start is around 900rpm
and thw hot idle of 650rpm whether its in park, drive, a/c on or not

theyre gonna lower back down for me to about 550rpm at idle

what would be keeping the idle held so long when i come to a
complete stop

there are no codes coming up

and i cleaned the crap out of the throttle body and intake before the swap
ran the 5.3 ecm for two weeks on the new set up
i had no sensor issues but it wouldnt idle worth a damn

the tuned ecm is better than the stock 5.3 to run the new engine
shifts really good

is my pu?/y bleeding? i am pretty anel about crap

i appreciate you guys
just looking for reassurance i guess. i know its hard for a tuner to
pinpoint without a scan cable.

i did have a guy in a 4 door toyota camry messing with me at the stop light
and yes he actually took the lead and kept it. from light to light
whats wrong with that?

at least it was a v-6 i guess

I won't be much help, because I know hardly anyhing about tuning, but I know I had similar symptoms of the idle hanging up after giving my throttle body a good cleaning.

Your throttle cracker is adjusted too high in your tune. It needs to be set to disengage at whatever speed you want it to drop to idle. Besides that, the throttle cracker airflow needs to be reduced and the decay needs to be increased. The rest is just something that needs to be played with until it is good.

Sux to hear you're not happy with your tune, but if you called the shop and Ray spoke to you and told you everything we'd do to make it right and let you know we're here to fix it, What else do you want us to say!

Your idle issue could be a few things.
You mentioned your idle used to be around 570rpms, now it's 670rpms, that's not unacceptable for your cam. And not unacceptable for me to raise it to 650rpms. We can put it back down to stock, but it's not recommended.
The "cruise control" issue you're experiencing, that shouldn't happen with the little amount of adjustment I've done to the idle section. If it did cause an issue, it's possible your throttle blade is a little more open than normal or your iac is dirty. This can always be put back to where it was.
The power loss ray explained to you could be the rest of TM hindering performance.
All this was explained to you over the phone and if you don't feel comfortable with the solution, I can't do anything about that.
What we can do , is to continue tuning your truck until it's correct.

farm truk
youre getting all butt hurt
and thats not the intention from me

i havent heard of anyone drilling the throttle blade in quit some time
Ray was very nice on the phone. We both agree that its hard to fix
issues with a mail order tune. I do feel the tuned ecm is comparable to the 5.3
stock tune running this set up. wide open throttle versus wide open throttle.

All i am trying to get at is getting this idle issue and maybe some back fire/pop
noise coming from this tuned ecm i installed. going all over the net trying to
read as much as i can. Im replacing the plugs for the hell of it. less than 900 miles on this engine. Im doing all that i can do( mechanical wise ) to get
my drivability they way i like it. I believe with what i have and 216/220 small
cam, a stock like drivability is not too much to ask.
With you coming on here and getting all festered with some drivabilty concern i have is nuts

I am open to Ray fixing what we discussed through nelson performance.
ive read damn good things about nelson performance for years.
