Review: HTE Tuning

I made some changes this winter that necessitated a new tune (higher flow injectors, colder plugs). I decided to take the opportunity to wipe years of continual tune changes and start from a fresh (CSL) stock tune.

Hassan (HTE) tuned my best friend's car 2-3 years ago, and I was always impressed how much it felt like a stock car (only with more power). His car, far and away, felt the most “stock” feeling (in the good way) of any tuned car I've driven. So, I decided to go that route, as well.

My full hardware setup:
CSL Engine management, with MAP
OEM CSL Airbox, no flap
Higher flow injectors (Bosch 0280156063)
One step colder plugs (Denso ixu27)
Schrick 280/272 cams
SS V1 stepped headers (with a bosch wideband installed in an extra bung for data logging)
SS HJS catted section 1
SS Twin tube resonated Section 2
SS Street muffler

The injectors really threw everything for a loop compared to a “normal” tune, but Hassan was great. He had a general idea of where they would be from previous cars, but we played it safe—exactly what I want.

First, fired it up and monitored AFRs at idle. All good.
Next, fire it up and monitor AFRs while holding it at 2000 rpm. Also good.

Then, the part that I think really has set this tune apart from every previous tune I've had—road tuning! Every previous tune I've had has been WOT runs on the dyno. He spent way longer with me than I would have expected, working over and refining the tune as I drove around. Full throttle, all sorts of partial throttle, all RPM. The car feels freaking great—never stumbles, pulls from all RPM, blips readily/enthusiastically, etc. I still intend to try the drivability spreadsheet for fun (and because it'll haunt me forever if I don't), but I am dubious there's room for improvement at this point.

I also have no doubt this tune is safe. Knock sensors are left at stock values, and we have a nice, safe 12.5 AFR from ~5500rpm to redline to keep it cool and knock free on track.

Haven't had it in on a dyno, because I frankly don't care so long as it drives correctly, but the car feels STRONG.

10/10, would buy again.

Because posts need pictures:

Ian you did this all on the road? How many pulls did you do?

I’m considering an LX570 for daily driving to replace my Odyssey minivan. The Lx is much higher off the ground - does it wallow or are the body motions well controlled? There will be no aggressive driving with this truck.

Well, my “shocks” are currently 197,000 miles old, so
not sure I’m in a please to judge. However, certainly currently it wallows.

This fall I’ll be replacing them (the AHC Accumulators). I expect it to still wallow, but in a more controlled fashion 🤪

At the end of the day, it’s a body on frame SUV,
with a hydraulic suspension. Body control is not going to be its forte.

Noooooo! Don't do it!

I have a list of common wear items to replace, to get this this back to as reliable as new... and it's kind of comically identical to my general e46 list.

Interested in hearing your opinion on the build quality and ease of work (especially compared to the e46). I’m not much of a wrench and have never worked on our LC, however our family mechanic always commented on how overbuilt and logical everything is on the LC.

[S14]

LX470's are excellent, and that one looks fantastic. M5 is a beauty too.

[Obioban]

Congrats on the LC, my parents still have their 01 they bought new. They’re definitely tanks but will require some maintenance over time.

Updates:
bought the Land Cruiser.
CORE One built and printing.

everything is as good or better than I expected.

I like his videos too! Didn't knew about the different axle on 250 vs Gx550 before watching this vid.

Thing is, most people buying a new 250 won't do offroad/rock crawling with it for the first 3-5 years! Most people overlanding is going to remote camp site with moderate offroad difficulty.

To take the LC250 off-road (due to low ground clearence), I think it needs 34-35'', skid plates for engine/transmission/transfer case/fuel tank/diff and also rock rails. No need for lift kit or suspension upgrades.

I love mine as a daily so far. The things I hate are the small fuel tank & stupid Toyota safety 3.0 electronics.


Ineos Grenadier would be really nice but will wait to see if they are still around in 2030... Love the B58 engine tho!

Agreed on all counts-- were I/we DDing it, I think 250 is where we would have ended up.

And, yeah-- possibly temporary companies are scary to buy from.

80s have airbags and ABS. They are quite agricultural coming from the cars in your sig though.

Later 80s do.

I think we have a reasonable compromise at the moment-- 100 as the practical car and she'll be okay with me getting a 70 to go with it down the road (speaking of agricultural).

Really, I unnecessarily threw her under the bus-- for the purposes we're going to be using this, I think the 100 is the best match. This is going to be more practical car than fun car-- the extent of the "fun" will be family overlanding trips. They're not going to be that hard core, with family coming along, and this should be more than enough for that-- and way more comfortable/easy than a 70/80 for the street portions.

I've been researching and test driving the gamut during this decision process. Contenders were...
70 troop carrier
80
100 (and LX470)
200
250
GX460 (J150 prado)
5th gen 4 runner (kind of J150 Prado)

In my estimation, the 100 is kind of bang in the middle of all the contenders. And the LX version adds xenons and a nicer stereo :P

The 250 almost happened because it's cool looking and... it would be nice to have a new car. But, in the end I don't really want to own a car with that level of complexity.

Plus, the more I learn about the 250, the most comprised it seems to secretly be:

Side note for anyone thinking about getting into this at all-- the above YouTube channel is bar none THE best engineering driven off roading YouTube channel I've found. He's semi local to me, so hoping to chat with him at some point.

His videos are consistently great. And, like modded sports cars.... SOOOOOO many people ruin their SUV with "upgrades".

[fattycharged]

Honestly, I really want an 80 series… but my wife insisted on airbags and abs.

I was looking into importing a manual/diesel 100 series, but it's 2-3x the price and finding a not trashed LHD manual diesel is borderline impossible.

200 series isn't for me.

Get the 80, its the right choice 😉
