summit and jegs have $100 off $1000 right now

Holley has a fixed price so everyone is required to sell at that price. That doesn't mean you can't find a better price somewhere. I use Tick Performance's "Team Tick Program" You'll probably have to call them to see what they offer.
I also use summit racing when I come across the 10% off coupons or one of their specials.

Yes, you can configure staging control. You'll need a Holley SSR and wire it appropriately.

Has anyone installed the Terminator Max system for LS1/4L60E, 4L80E combination and are driving the vehicle without problems?
Thanks

I want to give a friendly reminder t folks, given my recent experience.

A friend reached out to me looking for help with one of his friend's tunes. Engine is 370ci, healthy cam, flowed injectors, DBW. As far as he could tell it wasn't slapped together with gum and duct tape.

The issue was it wouldn't idle for ****. I looked at his tune...some logs...no smoking gun anywhere, except for odd IAC behavior and a high RPM flare at start-up. Given the symptoms, I immediately think vacuum leak. Sure enough, he had his valve cover vent hooked to the large port in the rear where vacuum brakes would go.

Lesson: before blaming the tune or the ECU or whatever, make sure everything is correct with respect to the hardware. Double check for vacuum leaks...and also exhaust leaks. Both of those things will wreck havoc with the tune and have you chasing your *** in circles.

Excellent advice... thank you

Price isn’t everything, service after the sale is important for an efi system IMO. We can usually match any deal or make a package deal with tuning. Most companies including Holley have map pricing so you should see it advertised for the same price everywhere.

What's wrong with summit's customer service? Holley has great customer service too, I've called before with questions . Price isn't everything but there's nothing wrong with saving money either.

Summit has great customer service, there is nothing wrong buying from them. We have a commercial account with them even. But does summit do installs or tuning, can they help with a base tune or wiring advice from doing installs or are they just reading from a tech card? We offer the same price and like to think we have more offer for tech support and customer service on Holley products over just a distributor. We are a distributor but also holley certified. That’s just something to consider.

^ just buy it from Lorenz. because while it is user friendly you will run into some simple problems that are just not widely covered. I've been messing with efi systems for a decade and I've had to unlearn some stuff basically, the holley takes a much more direct approach.

also +1 on the 4 port boost control strategy demonstrated by mister Mott Hoople I set mine up *exactly" like his---same proportional, integral and derivative control figure--- and targeted to leave on spring and ramp to 15psi and it worked like MAGIC I am super impressed.


also adding a FF sensor is highly recommended ! well worth burning an input for that!


and whoever asked about 60E/80e control yes it works very good. You will want to order a 0-300 psi 0-5v pressure sensor and build an input to finely tune your line pressure since the holley only displays the commanded % of duty cycle (as that's all it can read with the stock sensors)

I'm interested in this kit but I'm not sure which part number to get. I'm running an engine based of an ls2 out of an 06 gto. It is a gen 4 motor but has it has a 24x crank sensor.

edit, nevermind I found the answer to my own question. Looks like I need the 58x box and all I need to do is change out the crank sensor connector.

Or break off the alignment tab in the 24 tooth crank sensor so that the plug fits.

Who here is having good results with the TermX on a 4l60E trans ? The programming straightforward ?

LLLosingit

iTrader: (4)

You may already know this but I'm pretty sure the actual ecu is the same no matter if you use it for 58x or 24x sensor The ecu will run either or a custom configuration if needed. I believe the only difference is in the harness itself. Just pick the harness that matches your combination the closest so you'll keep changes to a minimum.
I want to try one just to see how much different it is compared to the Dominators and HP's that I have.

LLLosingit

From a software stand point, The Terminator X software control for the trans looks identical to the Dominator and HP software with one exception, The X software does not have an advanced tab in the software for Torque Management.
I haven't used the Terminator X/Max yet but have setup a Dominator ecu to control a 4l80e and it's pretty straight forward and easy to do. It will likely come preconfigured in the software and will not need setup other than gear and tire size unless you want to make changes to the base setup, The base setup worked great with only minor changes needed.

lemming104

Yeah, the only ECU difference between any of the kits is whether they come with the Terminator X or X Max ECU. The harnesses all interchange, and are all the same stuff that Holley sells for use with their HP and Dominator ECUs.

The way Holley does things, the following harnesses are all separate:
1. Main engine harness (plugs into ECU)--includes provisions for cam and crank sensor, coils, MAP, coolant, knock, and IAT sensor
2. Fuel injector sub-harness (plugs into main harness)
3. Drive by wire harness (plugs into ECU)
4. Transmission harness (plugs into ECU)

So, it's totally feasible to buy a kit that doesn't exactly match what you want, and then buy individual harnesses to make up the difference. For example, I'm using a 24x main harness and valley-mounted knock sensors, but I'm using a newer-style DBW throttle and EV6/USCAR injectors. It all just plugs in and works once you've got the appropriate stuff set in the ECU config.

I've got mine pretty good. Like was said above, put in your tire size and gear ratio and you are up and running. Then its a matter of tweaking the upshift/downshift curves to meat your liking, as well as your torque converter lock up speeds.

I haven't connected a pressure sensor and tuned anything with the line pressure.

Mine is a 2005 4L65e, from a Hummer H2, with a Corvette servo, and a Yank 3200.

Terminator Xmax has a couple configurations A) Drive by wire B) no DW but trans control both at $1300. C) both DW and trans control $ 1500.

lemming104

Yes, but those configurations are differences in included harnesses, not differences in the ECU itself. You could take a kit that originally had no transmission harness and add one later if you change configuration, or you could take one that had trans controls only and no drive-by-wire, and add drive-by wire later. Or you could use one that had the early-style drive by wire throttle plug, and switch it to one with the later style. My point was that, if Holley does not sell a kit with a combination of harnesses that is exactly what you need, you can order the relevant harnesses/sub-harnesses a la carte and get it to work by loading the appropriate ICFs when you build your tune.

Haggar

Yep, the ECU is the same for all 3.

Its really this:

A) XMaxx ECU + 1 harness ($1300)
B) XMaxx ECU + 1 harness ($1300)
C) XMaxx ECU + 2 harnesses ($1500)
