Are you running it as a full standalone or in parallel with the stock ecu? I have a map ecu for mine but I am considering running my other megasquirt 3 instead.

Everything on engine is controlled by maxxecu but stock sensors and gauges are still on oem ecu.
Engine light on maxxecu

Ok cool, that is what I was leaning towards doing as well. I prefer the megasquirt tuning method to how the mapecu does it.

Exhaust sound clip and second gear launch for those who have asked.
Taking a break while I'm in US for two months.
Thinking of bumping up to bigger Supercharger and selling this one early next year.

Seems Piston change in shape, increased compression. With Valve length the same, and believe only the VVT is a true interference engine. Would also indicate piston dome higher. No mention of change to heads' combustion chamber or length of rods..
So I suppose it depends on if your new pistons, if they match stock dome.
I dug-up, valve length spec, which are the same in VVT and non. Also history of 2UZ. Which happens to be 2005 Tundra VVT, USA made engine. Which was the Million mile 2UZ.
Valve length the same. Compress increased to 10.0:1 from 9.6:1, Piston shape change, Piston According to the compression ratio change, the piston shape is changed.

Check the valve overall length.
Standard overall length:
Intake: 95.05 mm (3.7421 in.)
Exhaust: 95.10 mm (3.7441 in.)
Minimum overall length:
Intake:
94.55 mm (3.7224 in.)
Exhaust:
94.60 mm (3.7244 in.)

2. Major Difference
The major difference between the new 2UZ-FE engine on the ’05 Toyota Tundra and the 2UZ-FE engine on the ’04 Toyota Tundra are the following: System Features Engine Specification According to various changes, the following specifications are changed.• Valve Mechanism• Compression Ratio• Intake Valve Timing• Max. Output and Torque• Engine Service Mass Cylinder Head• A lead-free valve seat is used.• The passage for the air injection is added. Engine Proper Cylinder Block• A lead-free crankshaft bearing is used. Engine Proper • Oil jet for piston is added. Piston Piston shape is changed. Connecting Rod A lead-free connecting rod bearing is used. Valve Mechanism Intake camshaft for the VVT-i (Variable Valve Timing-intelligent) is used. Lubrication System Oil passage for the VVT-i and oil jet for the piston are added. Intake and Exhaust System• The throttle body shape is changed.• The material of the intake manifold is changed from aluminum to plastic.• The air injection pipe is provided on the exhaust manifold.• The capacity of the TWC (Three-Way Catalytic Converter) has been
Piston According to the compression ratio change, the piston shape is changed.

Thanks for the info! Guess I know have 10:1. I went with stock CR listed as 10:1 Manley pistons.
Will see how that works at 15-16 psi
WOW, nice test of your new rods.

New supercharger ordered. ETA February for next phase of boost. 20 psi?
Goal : 500whp daily driver that looks, sounds and feels like stock until you need the power.
Then import it back to US in July 24 and likely sell it to buy a truck. Sucks but need a truck in US.
Will keep everyone who is still following posted lots of perfmance parts going in from vendors like Elate Mfg.
New Crank damper from ATI/ XAT

XAT for the engine parts if you want a lot of boost.
Up to 300whp I would keep engine stock.

I just need a bit more power with the weight and keep it reliable.
Nice work you are doing!!!

Easy to do with just an Elate supercharger kit.
Is the damper stock od?
Tundra motor swap?

Motor is 2uz that came in the Land Cruiser. Heads are stock. Rods and pistons upgraded during rebuild.
Damper in pic is stock OD. I need an Overdrive to match what I use currently to try and make 500whp. Currently at 420whp.
I would keep stock damper in place but needed the ability to get a little more rpm out of supercharger. UZ engines have crazy small crank pulley and it makes spinning 1900 Supercharger to get anything over 10 psi. With new supercharger I will try to go 16-18 psi
Currently i have an ASP custom overdrive pulley but it's just a welded pieced together stock damper and shop I am using for engine won't warranty the engine with welded together damper.
Switched to ATI super damper and Elate mfg will machine a pulley for me to match Overdrive size.
Sorry for the long explanation. Hopefully it makes since.
Stock 5.5"
ASP is 5.9" but welded together stock damper
ATI is 5.6" but bolted on to race certified damper
ATI will be 5.9" with a bolted on custom Elate pulley
It does, I am running the stock rr pulley and an asp underdrive crank. We will see if it works. Math wise it sounds like it will for what I need.
Edit: you said you needed a truck, I was suggesting putting it in a gen1 Tundra so you could keep the motor and get a truck.

Will probably go with f250. Have an offshore boat and may go to little bigger boat so will need heavier truck.
Someone is going to get an offroad monster LC from me haha. Right now it's just a bad ass daily mall crawler . Was going to do suspension and tires once back in US. Everything underneath is basically new OEM. Has stock rear locker, tjm front locker, manual trans, part time kit, etc. Hasn't been offroad since I started on performance mods. I did consider it but no way I can hack it up even if I sell for half what's in it (Alot $$). haha
Let me know how the ASP works for you. It has been great for me as an Overdrive pulley. Worth a few extra psi using TRD SC and then Harrop 1.9. Just need to upgrade for engine builder to be happy after balancing crank etc. They don't want a welded pulley on it and asked I buy an ATI damper or keep stock.
