Tuning Chips?
Another question for the day since I'm in a Corvette mood. I see tuning chips all over the place on Eckler's, Amazon, Zip. Do they actually make any noticeable difference? If you recommend them (which for some reason I doubt) which would you recommend. I am trying to keep my corvette as stock and original as possible while milking it for some fun performance.

I have an extra ECU for my car. Can I send it in to get tuned for lower fan temps and maybe a little more timing or is that all contained on that prom chip?

all within the actual prom carrier. The factory uses UV to update the Eproms. The upgrade mod would be installing a ZIF socket pressure less install.. along with a EEprom. To flash using a pocket programmer or similar.

Generic off the shelf chips are a waste of your money. A custom chip is what is needed for serious mods, but if you don't have any then you won't get anything from it.
If you only want the fan settings changed, they can do that in the chip.

I got the fan temp changed, vats turned off and some other mods from a guy on thirdgen.org with a new chip, so I can swap back to my stock. Cheaper than any off the shelf chip.

I just posted this up, came back from Dyno with a car I only know to be stock, except someone set the computer to turn the fans on at 185-195 deg, car always runs cool.
Anyways, cats, stock manifolds, glass packs in place of mufflers, no lump in the engine (no cam that I can tell), everything seems stock. 94, LT1, ZF6, pulled 290.1hp and 330torque at the tires! So 15% drive-train loss, thats 340hp and 390t.
If that's what you get custom tune with NO mods, color me impressed. BUT I assume some work had to be done, just not sure what.

I'm not sure the mail order stuff is good. Better than off shelf? Yes. Worth the money? Not for me. Not unless it is datalogged and they tweak it till there is nothing left to give. Other than that, I am going off your guessing. If I am going to do that, I'd rather learn to DIY and make my own guesses.

There are many corrections that can be made to mathmatically correct Open & closed loop AFR. Turn on the fans for better heat protection. Un- restrict a few more RPM's. Cylinder volume injector flow is also mathmatical. But for maximum performance. Not using manditory DataLogs. The results will be minimal or worthless. There are way to many variables. Example a mail order tune. Would never be able to individually adjust my injectors. Balancing via exhaust temp. I'M amazed All of the tables i have corrected with the small amount of simple upgrades on my current stock motor. The results have been very impressive.

I guess your right. 200+ pounds heavier.

Too bad that car burned to the ground in a garage fire. Bad wiring from an outlet to the garage door opener motor. :/

OK, your telling rexracer he should be 110+ MPH in a stock LT1 with 180K very few add-on's with 340BHP car weight approx. 3330 we all know air & temp will create deviations.
you were in a 90 ZR1 with underrated 375HP car weight approx. 3503 that pulled 111MPH VS 108MPH from a review.
spec wise 93 ZR1 is the slowest. There is only one way to prove this. 90 VS 93 stock ZR1 battle. A very unfortunate ZR1 loss. Hopefully compensated.
