Had ITR dyno tuned. Too lean?!
I have the standard I/H/E for my ITR and I had it dynotuned. At one point of VTEC, I noticed it is leaned out by 16% by adding the "vtec unmatched" and actual setting in wide throttle. Isn't 16% a little too lean? Am I calculating something wrong?

^^ You can't just pick an arbitrary value to lean it out. You need a wideband to see what the A/F ratio is. Generally, you can lean it out at WOT, but you still need a wideband to be accurate

^^ Thats fine then. I am sure that you tuner used an appropriated A/F ratio at that point. Normally, you can get the printout that will include the graph of A/F. I would assume that its high in the RPM at WOT that your tuner leaned out so much.

what did you use to "tune" it........if it was 16% too lean then why didnt you richen it up?

i dont understand what your saying..........how was it 16% to lean? 16% of what?
what was the air/fuel ratio while doing the dyno pulls? was the air/fuel graph smooth or did it dip up and down? |

Did u get the updated install instructions off of the website? The ones that come with the older models are wrongly wired.

The one thing you need to keep in mind for neetronics, is that the hp/torque numbers you will get will be lower than the ones you received at Dynapower. This is because he is using a Mustang dyno instead of Dynojet.

I trust Jeff, he tuned my previous car with the VAFC. and he did a great job.
As for neetronics, its basically the same ----..... rather then using a vafc he using his laptop. You can compare tuners as one is a master "Paul".. but I would'nt worry man.. Jeff is good. I |

Sure it give a you a reading but its like 25 horses off .. that why you only go to see Paul for safe tunning "making sure your car is running mint as far as a/f is concerned" and for power, you pay Paul a little bit more money and he will go with you to Jeff or any Dyno shops and he will fine tune "Set vtec. adjust timing "ignition/cams" ect.." Unless you have serious work done to you car,.., VAFC is more then enough.. with I/H/E, there no need to spend big bucks on Paul. |

As for his other bussiness its not for me to disclose. but he fully trained with everything he does. and the dyno is always kept up to date "calibration". |
I didn't know that his was 'home made'.

Does Jeff know his way around a Hondata?

What I am saying is that it was set -16 from factory setting on the VAFC. i would say thats normal......all honda's tend to run rich from factory anyway and a ITR would probably be more richer than any other.......... i guess it would be fine to use the VAFC if you just plan to stick with I/H/E mods. once you get into other more serious stuff the VAFC wont help you much......thats when you should pay a little extra to have the ECU professionally tuned. |

I'm sure there are others that play around, but Neetronics and another shop in ottawa are the only ones fully authorised. This is only refering to Ontario. |

I've seen him work on 500 hp subys, ITR's, miata's, the whole gaumet. This was when his shop was right down the street from Home Depot in Etobicoke. I wouldn't be too scared of the dyno. He's a stand up guy.

Your everyday dyno has auto load built in and its the same for every turn, as for Paul he controls it like the car is on the road. theres is nothing to be afraid of.. the only difference is that his is not accurate as far as HP/Torque and you wont get the pretty graph. Paul always tunes the cars on the safe side "A/f" , you have nothing to worry about bud. You have no idea the cars he deals with ... He does charge quite a bit but thats why earlier in my posts I mentioned if you dont have serious work then dont bother. |

I will go to Paul, I figure that since the mods are mild, it should not take too long to tune... |

similar to you, just boltons. when're you going? i've a few contacts so might be able to hook something up pretty good :)
i'll see when i can find time to do my i/h/e install and let you know |

call and talk to his assistant Andy.
He will help you . Getting a hold of Paul is next to impossible. |
^^^ ya, my friend informs me they're booked solid 'til end of may. talk to andy, 416-877-8831
