TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

Its marked as "old" as the previous owner swapped to new oem ECU.

 

I got some custom made carb sticker if you need them. They look exactly like TRD factory. I gotta find where I stored them. I had some made because Toyota wouldn't sell me the dam sticker unless it was installed by them.

 

My mistake! But it looked as stated initially. I’ll take it.

 

I actually had someone else pm me about it beforehand already. Pending payment.

 

I didn’t have any trouble getting a sticker and didn’t have to pay anything, Did you get denied at dealer or after calling corporate? I think I posted the phone number somewhere a few years back.

 

Got some interesting data for you boys that I feel like the domestic boys don't deserve due to their general "know it all" and "matter of fact" closed minded attitude when it comes to generally new tech and mods implemented in vehicles.

I swapped over to a lithium automotive exclusively made battery for my Z recently and really only wanted it because my AGM was acting really fucky recently. Being that it is made for automotive applications I figured why not. My initial impressions:
- Checked resting battery voltage and found 13.3v at rest prior to install
- The usual 11.8v to PCM at key on engine off (this is PCM regulated and normal)
- cranked up INSANELY hard and fast in comparison to the old AGM battery
- start up idle flare was non existent now
- 12.3- 12.6v at key on engine on to PCM (again, PCM regulated and normal for this platform)
- 14.6- 14.7v while engine running across the general system outside of the PCM

After my initial fears of running a lithium on a vehicle with an alternator and running my car for a bit at idle in the garage, I grabbed the fire extinguisher just in case and went out for a ride. I found an increased fuel economy (E85 economy) while cruising of at least 2 MPG, if not 3-4 MPG. I currently do not have enough logged mileage to be able to say for sure how much exactly my average gain is but I am seeing much more city and highway economy numbers out of my dash then I ever used to see on average. I was not expecting this at all and is a huge gain for my setup considering E85 loses a considerable amount of economy in comparison to 91-93 octane fuel.

The real story, however, is in the increased pep and power that I found it gave me. I hooked up HP Tuners and went for an intentional ride to do some logging. What I found shocked me. After performing a WOT run I did a before and after comparison of the setup with virtually nothing outside of the battery itself being altered otherwise including the current tune in it. I found a new overall HP/ TQ output on the vehicle and the gains were substantial:

Before battery- 709 HP/ 772 TQ
After battery- 737 HP/ 779 TQ

These gains were substantiated as DA was very close when comparing to the previous logged run. Injector PW's were higher, MAF frequency was higher and riding the bleeding edge of the current table it typically maxes out at (10,101 Hz previous max compared to new 10,230 Hz max) and IAT's were a 10 degree difference from log to log. The wideband error from actual EQ commanded previous was -1.3 before, and is now -1.8. Just in case anyone wants to know the MAF has not been rescaled so the numbers displayed on my logger setup are accurate indeed. Cylinder airmass was .3 grams higher than previous meaning yes the engine is breathing more to further substantiate the claim that more power is being made now.

My case in point being that wow, I didn't think there would be so many side effect benefits out of this thing but because this vehicle is so electronics heavy and dependent (including the low pressure fuel pump which is driven by a control module) a 28 HP/ 7 TQ gain on the vehicle was able to be realized.

Not the same platform obviously, but it was a surprise way unexpected to me which made me much happier than I thought I'd be.

 

p..

am i correct to understand battery performance reaches much farther than previously known? i dont need a new rabbit hole. but knowledge is great! im interested. cant wait for you to tell more.

 

Wait, you have a Z now? Where’re the pics!?!?

 

That is exactly what I'm stating here.

I really didn't expect much as far as a performance improvement went because voltage is voltage after all and the alternator only works within it's designed constraints, but apparently if the battery voltage is capable of maintaining and matching voltage stability closer to the output of that of which the alternator demands, the system is less strained under any particular voltage/ amp draw situation because lithium batteries have more of a linear drop in voltage vs dips like lead acid wet flooded/ AGM tech and the system can work with less stress on it.

I was just as surprised and what started out as wanting better capability to start and just being able to use electronics without fearing the battery going dead wound up giving me improvements across all fronts of performance and functionality. I'm not easily surprised these days when it comes to performance stuff and usually know what to expect, but this one threw me for a huge loop.

 

I've had it since last April! 40,000 miles and I already had to do a build on it (not because I wanted to, but because I had to).

 

Been running the antigravity battery for a some time, the real benefit is the weight reduction.

 

I have been running a lithium battery for a while, I have seen no increase in mpg's. The start up is fantastic and quick, like you have noticed. The significant drop in weight is very nice.
You the numbers you are seeing, now this is just my 2 cents on it, I would contribute that increase to the cooler temps now and probably less work by the alternator charging the battery die to the higher energy density of the lithium battery.
But, I an glad to you have that big of gain. Congrats!
Side note. My lithium battery was installed about 2018.

 

We can run lithium in our 2nd gens?

 

Yes. That battery electrics for charging and sell balancing is built in to the battery. Just make sure it has it built in. I think some for the solar or R.V. applications may not have the battery electronics built in.
Edit: over charging or over discharging a lithium battery is bad and dangerous. That is why there is lithium battery fires. Well, one reason.

 

So would it be better in a dual battery setup? So it's always accessory?

 

Not quite sure I understand what you are trying to ask. Can you explain with a little more detail?

 

Oh sorry, um because you said it's always not going to be over or dis charging so if it was an additional battery then you wouldn't have to worry about it charging too much?

 

Yes. I would look more into auxiliary battery applications to make sure. And to don't charger them above 14.0-14.2. I think that is what my manufacturer state.

 

Sweet ride. Looks fast!

 

Indeed! It is a lot nicer putting in the lighter battery instead of heaving in a big gaping heavy AGM.

I'm a little taken back by what I saw. I don't see a 10 degree difference, however, giving me THAT much of a power gain though, because what I saw was substantially different from previous logged efforts.

Now we can, yes! You do have to make sure that you find an automotive application specifically built lithium battery because they have tech built into them to be able to handle the charging demands that alternators put out.
