Tuning a C8 Corvette Global B E99 ECM - HP Tuners (Part 1)

[phone] | [e-mail]
Steven Fereday of Late Model Racecraft goes over the process to utilize the HP Tuners process to tune the Global B E99 ECM. This will be a multi-part series documenting our experience that has been 3 years in the making.
As many know the GM vehicles on the Global B network with E99 ECMs are locked and limit nearly all abilities to tune the vehicles. Now that HP Tuners has finally accomplished accessing the code, we are now granted access under the HP Tuners network to calibrate tunes just as we were able to in previous models.
Late Model Racecraft is now accepting C8 Stingray Corvettes, CT4, CT5, Blackwing and Esclade V

With this new tuning, how far do you think the hp can go without boost

[@rrace002]

It can go further without boost, but with boost it will get you to the destination quicker.....

[@Bamabrute85]

Heads, Cam, Holley Hi-Ram, E85. I'd say 600 whp will be pretty easy to do. I wanna see a 427 LT2 with higher compression.

[@boboso7238]

Not a tuning question directly. Now that the HP ceiling potential has been raised with this ecu unlock accomplished, how far behind is the clutch game in order to keep up?

[@HennyTRX3773]

Do they make a roots style blower for this platform yet

[@cali2468]

Oh man just wait until they unlock the ECU in the C8 Z06. With boost the power is going to be incredible.

[@deanfrancis6474]

Well done. I am curious as to what GM thinks

[@every56days]

Whoever your barber is deserves a shout out. That’s a world class cut, sir!

[@jayjones3458]

Voids warranty??

[@BC-qm1mb]

Towards the end of your review, you mentioned this new setup it will make these types of tunning/upgrades a lot easier. Will that translate to some additional cost savings to future customers?

[@cedricedemps]

It would be great to see the results of a tuned NA build with Exhaust intake Something basic

[@AJUSA1]

What does a tuned e85 N/A c8 dyno at and run the 1/4 in.?

[@BrakinBank]

Can not wait until im able to drop off with yall ❤

[@thegreatgatzke1]

I would like to know the difference between stock ecm and a tuned one with no bolt ons then crank it up with turbos. Can't wait, finally.

[@eugenec4957]

If possible, when you guys tune the first C8, can you do video just with the car being tuned with no bolt ons or anything so that way people can see the gains that it can get, then maybe do one with headers tuned because we know the gains that the headers make off of your previous videos without it being tuned but now, with the two maybe more people can see what the car can actually do with the tune and headers.. Besides the new mpvi 3 was there any other hiccups to prevent the download of the tune?

[@thiosemicarbizidebenzoylal2921]

Trifecta has a webpage stating little to no gains on a stock engine with GMs state of tune vs a modded car.

[@ParagonPerformance]

@@thiosemicarbizidebenzoylal2921 There's also someone claiming 20hp on a stock car so who really knows.

[@cali2468]

@@ParagonPerformance 20hp bump with no mods?? I doubt it.

Now the C8 DEMON'S can come out 😈😈😈😈

[@joepisciottajr]

Means all these channels will put out lots of C8 content.

[@patrickciarcia4100]

Great informational videos… 👍🏻😎🇺🇸

[@stephenturley1189]

What is the fee to unlock? How many credits to access it afterwards??

[@avon2alpha676]

Question is what is the total turnaround time?

[@LateModelRacecraft]

Depending on what we're doing. Hp Tuners was a 2 day turn around + shipping to and from.

[@MrMaverickz28]

Yes yes yes yes (one more time) YES!!!!!!!!

[@boywonderrr71]

YES!! Tuned C8s will rip now!!

[@ronp5746]

desparate for your help.... my 2021 z51 HTC was done at a competitor and I got it back April 20th ... it keeps throwing codes and going lnto limp mode. There is a Maggie on it etc...

[@matthewrandall915]

U would think that Chevy would offer for a fee to unlock it. Get their lil piece of the aftermarket world 🤷‍♂️

[@Bamabrute85]

How well does a big cam and a DCT get along with one another? Probably a dumb question but I've never really thought about it until now.

[@John.Manners]

Here for a big choppy cammed C8. Let’s hear it boys!

[@NoMatter78]

Thank you for the great informative video.

[@Goczku]

It will be something epic soon with tuning new cars

[@Steven_C63s]

Hay man hope all is well. I just have a question I have a 22 c8 HTC I already have a Paragon Tour Exhaust. I’m thinking about putting either a attack blue filter, or a intake. Will this HP tuner gain any horsepower on NA cars? or is this tuner pacifically for boost? So basically, my question is can you gain anything with basic Boltons? Lmk thx

[@rrace002]

Is it possible for you to make a base-tune calibration for the c8, so it doesn't need to be dyno tuned?

[@kirkcunningham6146]

I doubt it was cracked. I would bet HP Tuners now has a license deal with GM. Also, they may be giving us only what they want us to have. 🤟

[@ClickbaitMotorsports]

This. 💯

[@ARXDMOS]

Is the dct tunable or are we going to have another dud like gt500 with untubale transmission

[@mrjayare81]

Can I get my car to pop and bang more and shoot flames with a straight pipe exhaust and tune and gain more horse power as well?

[@larrynewberry3500]

I know it's early, but do you have any idea how long before ZO6 will be cracked. 1 to 2 yrs maybe.

[@chrisbriggs9418]

Hell yeah!!!

[@breakupgoogle]

Finally cracked!!!

[@bmaxmod85]

Does the e99 have a flex fuel port?

[@LateModelRacecraft]

It’s already being used, but give it time and we will have Flex setups for these in the near future.

[@chriscrowell6678]

Just curious if the MPVI 3 is a " MUST " for tuning the C8 E99 or is the MPVI 2 and 2+ still capable

[@LateModelRacecraft]

MPVI3 is a must

[@RobertMacCready]

So, am I understanding that if I bring my "stock" C8 in and just want a "tune only", it's between 3 and 5 thousand dollars? AND I can tear up my warranty!!

[@cali2468]

Why would you tune a bone-stock car? 🤔

[@2020matrix8]

Hell yes 💪🏼💯

[@betonblack3621]

So ready for cammed C8s lol

[@crodrc51able]

Would be cool to see a Stingray with a full top end and properly tuned. But it will be expensive. Unfortunately that means no more new performance cars for me. The Vette and the Mustang are pulling the same crap, if I buy a car it is mine I’m not renting the ECU from the manufacturer. Plenty of good C5’s, C6’s, and C7’s as well as Camaros, Stangs out there for decent coin. I don’t have to have the newest and latest thing. For those out there with the coin to spend, we will have fun watching the builds and seeing what can be done. I knew good ol fashioned American ingenuity would crack the computers. 👍💪🇺🇸🦅

[@thiosemicarbizidebenzoylal2921]

Hold up, didn't TRIFECTA have their unlocked ECU first?

[@kurtthomas4746]

Hi, I believe you are correct, I have a ProCharger on my C8 , in stage 1 form it didn’t work that good, then stage 2 came along which consisted of pulling out the ECM , and sending it to Trifecta, I believe they installed the tune that ProCharger developed for it with them. The shop took out all that stupid piggy back stuff for stage 1 , replaced the ECM, and it’s a totally different car, picked up almost another 100 rwhp, stock was 436, stage 1 was 520s and now stage 2 is 615 rwhp, car works great, transmission works better, extremely happy now.

[@longrider50]

I believe locking the ECM's hurt GM's sales since many folks who buy these cars enjoy getting more power out of them. Looking forward to upcoming videos.

[@shadyshinichi2JZ]

Hurt their sales? There's a wait list for purchasing the C8s, and they stopped accepting Z06s orders lol. GM wanted to get through the cars release before people went crazy with tuning them.
