LET C32 2002
Hey c32used:
I am NOT claiming it, Tuners like Code3, and others on this board HAVE claimed it for me. I am AGREEING with them, that there is enough head room left in our ECU's for a simple pulley swap. Did you read the entire thread?
YES, I would have LOVED to have had other tuners chime in, but alas no luck. I will not try and persuade them, as I am sure they have their own reasons. Which I will not get into as this was a simple poll as to what works, and what doesn't.
I am simply stateing that a tune is NOT required by the evidence form this post. Evidence like the A/F ratios that were stated above from REAL data logging.
YES, if you want every last HP, like some do, then get it tuned. For me, I will save the money and sleep VERY well at night.
See yeah

[QUOTE=c32used; So lets keep this open for a while to let others who may not have seen your thread a chance to say something first. Even Code3 on his website has ECU tuning available soon. As long as profits are challenged we will never know.. I am done Take care and God bless.[/QUOTE]
Its all good c32used.
No problem, hopefully more tuners will jump on board, however I am inclined to agree with your post.
See yeah my friend
PS: It's never personnel, its just ALL good fun and info

Your ECU can be re-coded for your VIN with the STAR machine at the dealer, but I think it will need to be re-flashed after that, destroying your "tune" inside.
A competent tuner can recode without destroying data, but it would cost about as much as a tune anyway.
The bargain Crossfire tuners I've seen are simply reselling tunes, not developing them.

This thread should have been titled differently.
What most people are forgetting is that the maps we (tuners) modify are a starting point / guideline for the engine to follow. However, because of the nature of the ECU, it can and will change the parameters as it sees fit.
For example, if your IAT's are 35 °C - 45 °C, the ECU will retard 3.5° of timing at full load. A tuned C32 will have a higher degree of timing at any given level, so when the 35 °C - 45 °C mark is reached, the tuned C32 will be making more power due to the increased timing and fuel. A tuned C32 is also a better performer in hot climates....for obvious reasons.
Now, let's assume the tuned C32 is slightly different due to 89 octane fuel. If the car knocks at the top end, then a calculated amount of timing will be pulled and then the tuned C32 could possibly be drowning in fuel instead of burning it as normal. In this case the stock tuned car might perform better.
You should never throw any "tune" on your car. I would hope that at the very minimum, it would be tuned for the gas in your area.
If you take a custom tuned Stage II C32 with a HE and JP, and compare it with a C32 with the same mods, same day / conditions, minus the tuning....the custom tuned C32 will always outperform the latter.
I have had the pleasure of playing with our files personally and speak from experience...not hearsay.

Pulley, headers, and a heat exchanger. No tune, yet.
Runs okay, but I'm almost certain there is some more power just waiting to be unleashed.
Maybe after the tax man gets paid.

That has been my WHOLE POINT. a tune will get a little more out of her, but it is NOT a requirment. I agree that without a tune, you leave alittle on the table still, but at the prices most tuners want, except LET, its INSANE
Thanks again
See yeah

You are one of the people that I was hoping would chime in.

PS; The title was there for a reason, this was suppose to be a simple poll on pulley installs and the need for a tune. Somehow, it became ALOT more. Thanks again
