Storm 1UZ

[Victorgaragesmg]

Anyone have work with this ? 

1st gen 1UZFE 

No vvti

But i will make it to individual coil.

Using K24 coils

Can i still use the stock trigger pattern and home ? Which os 12 + 1 i think

Thanks

[koracing]

The stock triggers should work I believe.  Most Toyota from mid 80s to about 1996 used 12 tooth crank and a single tooth cam sync, so I imagine yours would work with that as well depending on year.

Thanks. Anyone here with more info please. 

As we know.. if running traditional.  I gonna need base injection

Anyone here have the base setuo cak for stock 1uz pleaze share.

Tdc offset, trigger arm, and home arm voltages. 

Injector size.

Basic set up from the help file below.  From memory they have a cam sensor on each side of the engine and the trigger offset is 360deg different depending which side you use.  So trigger offset may be around -4 as below or 356 for the other cam (I dont know which cam our data was based on).  

There is a 1UZ Atom base map in G4X PC Link.  It is only a basic start up map and not from a tuned engine.  If using traditional fuel equation you dont really need to know injector size, just adjust the master fuel value until it starts/runs.  I would expect if using the stock 251cc injectors the master fuel setting will need to be up around 20-30ms.

Email me, in the process of tuning one now.  Have a good start.  It's a stormx though, just have to change to wasted spark and paired injection after connecting to ecu.  Email me at [email protected]

Hey thanks 

I usually use tuner stuido ms to determine the base inj value 

So triggwr and home arm voltage are the same ?

Done sir thanks

Most likely, the waveform amplitude and the noise floor are effected by many things that the ecu has no control over, but usually the values above will be a good starting point that will work for most.  The ECU has a trigger scope built in that you can use to confirm arming thresholds are accptable later if you have any doubts.

Adam, should I pair injectors same as ignition as i use semi seq mode

and wasted spark 

36-1 trigger

Can i ask the same question to adam. 

Should i wire the injectors like the ignition. Or by banked ?

Run semi seq

[Adamw]

If you only have a crank trigger and no cam sensor then you cant run semi-sequential, you will need to use multipoint group (injectors will fire in two groups alternatively).  If using multipoint then wire 2 injectors of 1 bank to inj 1 and the other 2 injectors on the same bank to inj 2.  Then on bank 2, 2 injectors to Inj 3, 2 injectors to Inj 4.

ok so INJ1 is 1 and 3 , INJ2 is 5 and 7 , INJ3 is 2 and 4, INJ 4 is 6 and 8 ? 

is this correct?

[Adamw]

Yep that will be good.

Thanks adam.. its worked fine. And run. 

So injection mode is always banked when no home is present ? 

Semi seq need home ? 

If i use the home signal. How should i wire the injectors then ? 

Like firing order pair ?

The ECU will still allow you to set the injection mode to sequential, but without a cam signal the ecu doesnt know whether it is on intake stroke or power stroke so the injection event will sometimes be correct and will sometimes be 360deg out.

Yes, sequential or semi-sequential means the injection event is synchronous to the engine cycle, the fuel will be injected at the same point in regards to engine cycle every time.  You need a cam sensor to determine position in a cycle that is 720 degrees.

The 1UZ doesnt have a great firing order for true semi-sequential, but it still gives an improvement over multipoint group.  Explained in the help file with an example for a 1UZ:

ok got it as long as its 1uz i will pair as the factory

other v8 pair as firing order?

this all happesn when we use 4 drivers injector right ?

how if i use 8 drivers from storm? will i just wired it according to cyl number ? 

say if i want to use multipoint or semi seq.

Yes some will allow true semi-sequntial, other may not.  I dont personally know which ones off the top of my head without doing a bit of research.  You can often make one work that doesnt have a suitable firing order by fudging a combination of the firing order in the software and the wiring to coils and injectors, but I dont like to do that as it gets really confusing to the tuner when cylinder numbers dont match etc.

  If you had a Storm and a trigger that was capable of semi-sequential then you would be best to use proper sequential, no need for semi-sequential if you have enough drives.  

For sequential you wire Inj1 drive to cyl 1, Inj2 drive to cyl 2 etc.

I understand that. I just want to learn how the link work. This is my forst time using wasted spark and semi seq or multipoint. 

I need to really understand how the ecu work. 

I am getting used to haltech, motec, fueltech  maxxecu. Now i need to be able to work with link. And if i cant have trigger support. 

The 36-1 trigger also full custom made by myself. So i can aply it to other engine in the future if i dont have the trigger supoorted. 

 

Thanks adam. I will back asking u again of i got some other questions. 

You have been very helpful

[Adamw]

It would be pretty rare to need a custom trigger with Link.  Usually we can add it pretty quickly if something new comes along that we dont currently support.  

Usually it is only older engines that didnt originally have efi that you would need to make a custom trigger for.

Yes indeed sir. Or like bmw m52 that hall in crank but frequency on home. 

Sometimes like that.
