You fellas are great. I bought the Haynes manual and search the threads on this site so I should be able to cut down on the dumb questions some but sometimes answered questions lead to more questions.


It seems there is a cam sensor and a crank sensor and from these two data points ignition timing is established? If over time the timing chain stretches/wears and allows a couple of degrees/minutes of slop, does the PCM recognize this and adjust accordingly. Does the PCM "think", if you will?


From reading here it seems there two ways to "tune":
1) Go to a dealership mechanic or other competent shop
2) Buy the hardware/softwear and do it yourself


If that is the case


1) will they allow custom tunes or will they only work to an industry standard.
2) I guess you must really have to know what you're doing.


Thanks again, I really do appreciate your time and willingness to share your knowledge and experience.

 

Hi Bdorrman & Welcome to our Monte Carlo Family.

What year Monte Carlo do you have ? How many miles ? Do you have any modifications ?

Please check back to see what our expert tech's post on your questions. Yes, your auto computer can be reprogramed or re-flashed.

What are your goals ?

Wish you safe & happy miles in your Monte > EnJoy

 

on your timing set there is a slack adjuster that keeps slack out of the timing set so slop doesnt happen.

the dealership can not custom tune a vehicle they work with factory specs only. if you want a custom tune you need to either buy the tuner (hp tuners or dhp) or buy a mail order tune from overkill, intense, zzp etc.

 

Thanks `John for your post & sharing your knowledge with member's

 

With the Diablo tuners you can save off the factory tune so when you take your car to the dealer you can restore it back

Diablew offers a performance tune and can be done over you computer just a file transfer

 

Thanks Tadcaster, this looks like my next area of research. Not because I'm planning to put a tune on my MC, I don't know what I want to do with it yet but because I don't have the slightest idea what you are talking about in that 2nd paragraph. Off to Google!
