Looks like Holley just got some competition. Too early for pricing but an interesting option coming out. Their new app is looking interesting too.

Yeah I just ordered a R3 a few days ago. Weird timing haha

I can't see it being cheaper than the elite 2500 with harness (2,800$), or R3 with harness ~ (3,200$~3,800)

So likely not a terminator X competitor but may force everyone to step up their game. I know MSD/Holley has some products upcoming that can do tune by app via blue tooth connection to phone


My buddy is at SEMA and I asked him to ask some questions for me. If anyone has any questions I can pass the word along to him to harass em

 

I’m hoping it’s less than $2000 all in, but wouldn’t be surprised to see $1600ish based on the way they are marketing it as ls specific. I think at that price point it won’t be a huge jump for people considering a terminator x max. I think I saw they aren’t including the advanced traction control stuff but if they include most of the rest of the nsp software capabilities it will be a serious unit.

 

They seem to be harping the fact that it'll be competitively priced and LS guys will want in so I guess we'll see. I am seeing a lot of people getting tired of Holley and wanting another option.

 

I was planning on picking up a Holley Term X this winter.

What are people getting tired with Holley about?

Do you think it'd be worth waiting on the Nexus Rebel LS?

 

More and more threads with problems have been popping up lately. It’s a very basic ecu arguably designed specifically to leave you wanting more.

the haltech will absolutely be a better ecu. Whether or not it’s price point makes it a valid comparison is yet to be seen.

 

Unless you're itching to get something installed and fired up, I would at least wait until they announce the pricing on this new system. The new Haltech Connect App looks interesting as well.

 

Then this just apparently was released.......

I’m amazed at how vast the hpt product lineup already is. Reverse engineering every domestic ecu is a monumental task and now they’re adding a standalone.

 

In certain instances they only have 1 person assigned to a given platform so they must have a serious staff overall. I assume that there must be some decent reuse between some platforms and they may have an in with some OEMs or it would have taken forever to get everything they have.

 

Define "better." I am not being a dick here, just trying to get a perspective.

I tune Terminator X and X Max ECUs everyday. Do they have their issues, of course, but I promise you that every manufacturer has their skeletons that occasionally fall out of the closet. LOL

Did anyone else find it odd that is lists having 2 labda sensors but nowhere did it say whether they are wideband or narrow band. That's a really important point. They are either concealing the fact that it uses narrow band O2 sensors, or someone in their marketing department missed a really important selling point.

I have an elite 2500 and its been a damn chore finding a tuner in FL that will even touch it. It looks like ill have to rent a dyno and have it remote tuned which is definitely not fun to deal with. Holley has much more support

 

It specifies ability to set a target A/F ratio, so they would have to be wideband. I am more interested in the part that says you can control individual cylinder fueling.

 

a stock ECU can set an AFR target as well as move the stoich point. It doesn't guarantee that they're widebands, but it seems like they must be and just didnt say it explicitly like PG said.

 

ive tuned both. the terminator is a very simple ecu and as a tradeoff lacks control of many things, by design. one example, the new haltech has solid state power output for coils/injectors, fuel pump and fan to eliminate relays and give software configuration of current limit (e-fuse). likely they will leave in the pwm control of those lines as well since the other ecus have it.
by better i mean its just a higher end piece and the price will certainly reflect that, its just up in the air what that price difference will be and how easy it will be for people to jump that gap. can you argue that a HP is not 'better' than a terminator x ? i dont mean to say the terminator x is total trash, it has its place and has probably done more for the ls swap community since it came out than just about anything.

 

im by the space coast and will be receiving my dyno in december and begin dyno tuning early next year and haltech is my ecu of choice.

 

their comparison spreadsheet says it has two LSU4.9 controllers

You may have a lot of business if the rebel hits a good price point
