To upgrade ECU or Not...

[GenesisCoupe]

Off-Topic; There is an ECU Tune available for my car. It is not so much power increase but the following;

*New Fuel Maps
*New Ignition Maps
*New Cam Timing Map
*New Throttle Changes
*Increased Rev Limiter to 7200 (Manual Transmission)
*Top Speed Governor Increased
*Absolutely more power throughout the WHOLE POWERBAND

This Tune will work with STOCK and most bolt on's by adjusting the AFR through a target lambda system.

The tune costs $500 to tune the stock ECU, or $850 to get a brand new tuned ECU.

I am also planning on getting an intake, whether short ram or cold air, but my question is...Is it worth it for a naturally aspirated car? The power increase is about 10hp/10tq

Thanks for any input!

Go for it. I had a PCM tune about 4 years ago and love it. Much more fun to drive. And better mileage is a nice byproduct.

Just having the improved throttle response is worth it to me. My friend put a tune in a 07 mustang GT and he can chirp third gear with exhaust and intake.

With the Genesis having an 8 speed it sometimes struggles to find the right gear, takes about 2-3 seconds so hopefully that fixes it! At 43 mph it is in 8th already!!

Here are a couple of things to consider:

- Is your ride still under warranty? Loading or changing the stock tune may void mfg.'s warranty.

- How is the tune flashed to the ECU? Handheld tuner or done by a shop (added expense)

- If adding/changing to cold air intake, in most cases tune will need to be changed to allow for more air (free updates of tune?)


This is what I use to load custom tunes onto to my mustang:

Bama SCT SF3/X3 Power Flash Mustang Custom Tuner w/ 3 Free Custom Tunes - 3rd Generation SCT XCalibrator 38018 (96-14 All) - Free Shipping

From my tuner, I receive free updates as long as I own the car - except for a supercharger as thats a whole different animal.

Is it worth, for me it was! I didn't care about gas mileage as thats all dependent upon my right foot.

Hope this helps...

Thanks James!

Yes the car is under warranty, however the shop states that the tune will not be detected by the dealer as the tune keeps all stock scanable parameters untouched.

I would get the intake before the tune, and the shop can pre-tune the ECU to the intake before sending it out to me. They specialize on the Genesis so they have everything they need.

Kinda sucks you have to change out the ecu for a tune...having the SCT handheld allows me to flash the ecu anytime I want. There's no handheld option available? With a CAI you should get at least 20-25 hp increases. How easy is it to change out the ecu?

Well I don't know about Hyundais, but on Fords the dealer can tell if it has been tuned even if it's been reset to stock.

I have an SCT Xcal3 with custom tunes for my truck. The biggest positives for me were instant throttle response and improved shift strategies. Can't even tell my truck has bigger heavy tires anymore and it will chirp them in 2nd.

If you're concerned about your warranty the slightest bit, I wouldn't do it. Yes, technically the dealer would have to prove the tune caused the issue under the moss magnuson warranty act, but lawyers aren't cheap.

I'd find a Hyundai or Genesis forum and see what you can figure out.

You will not gain 10hp from an intake. Don't fall for the marketing bs.

Actually it`s been proven that intakes provide great gains on N/A engines. It`s really not worth it for turbo`d cars unless there are quite a lot of other upgrades that go along with it.

OP, I say do it. Send them your ECU to be tuned.
